Hello, the 1.25mm is pretty close. The problem I found was that DJI specifications are slightly different causing a problem with the the fit. I was using DJI donor connectors for the best results. In my opinion this enabled DJI more control over their products. Best of luck to you

@@RichJ53 thanks a lot for your quick response. I do not think these are proprietary. Even with the numbers of batteries DJI makes, that would not be worth it. I was in charge of industrial design at a very large global electronics maker, I think these are standard JST board-to-wire connectors, I just do not know which ones. There are so many. But still thanks a lot for taking the time to respond, I really appreciate it!

@@rogiervdheide you’re welcome.. you are probably right about proprietary items or special connectors. I just didn’t have much luck buying them in small quantities or that fit into the DJI socket. They also control the end of life of their products by making it difficult to get aftermarket parts to work. Hope you have success with your project. Rich

Yes, that’s my experience as well. I setup a negative 9% down elevator mix to full flap for the first flight… wow it dropped quickly Zero mix was perfect on the second flight! Thanks for commenting.. Rich

Thank you.. yes, the JP test stand makes a very stable work area. I didn’t set the scale on the second run. The intention was to familiarize myself with Jetsmunt turbine operations .. noise cancellation on the camera definitely makes the true sound cut out

Hi David, thank you. The weight is 25.25lbs and wingspan is 2.2M or 86.6”. Take a look in the description for more details or I can try to answer here. Rich

@@RichJ53 Thank you. I am getting a Wind R/C MB339 and putting a 140 in it. A bit high on the power, but i don’t fly at full throttle much. It will be good for the vertical!

@@Davidjones-sk4vf Hi David, That will be a very nice flying jet! Chief Aircraft is importing them (awesome) I had one (HSD/JMP) had a SW120 which was very over powered. 140 will be crazy power in this light weight jet. Check out my other video of the MB339. all the best Rich

Hello, yes I have photos of the control decks inside the jet. I did not have a build thread, sorry. What questions do you have? Not sure how to post photos here thanks for watching Rich

@@RichJ53 I got the same plane. Even though I put the batteries and the UAT in the nose of the plane, the tail was still too heavy and I need to put about 500gr in the front for the CG point to be 175mm. Have you encountered a similar problem?

@@tyfugr1976 Hello Yes, my Jet was tail heavy. I added 8oz of lead shot in the tip of the nose. I had to remove the nose retract to pour the weight up inside the tip of the nose with epoxy. I would recommend using 168mm CG for your first flights. 175 will give you some unexpected wing stalls. What turbine are you using? Did you get it as far forward as possible keeping the pipe alignment?

@@RichJ53 thanks

Yes, because the RC jets outnumber the real ones! It’s to bad the Viperjet company couldn’t compete with the L39’s Great aircraft Thanks for watching Rich

Hi Scott thank you for watching. . Rogue Eagles RC club Agate skyways

Hello Marco, factory recommends 160-177 mm from the wing root my CG is 175mm the flaps are at zero mix to elevator on my jet. My first flight a had -9% elevator mix and the jet dove badly so no mix needed and worked beautifully.

Thank you Rich🙂

@@colibripr. your welcome If you can put the flap to elevator on a flight mode and this way you can trim the elevator on the fly if required. All planes fly differently :) Let me know how it goes!

@@colibripr. Aileron: 20mm, Rudder: 25mm, Elevator: 20mm. Flap: 35mm for take off and 65mm for landing.

Hi Rich that was a beautiful, flight & landing, I havlooks to be the same other than color I have a wind rc jet 2.0 mm viper yellow & black going with king tech 102 G4 I read that your CG is 175mm from wing root you heading says yours is 2.0mm but the guy that asked said he had a 2.2 or maybe I misunderstood thanks

Thank you Lars!! Hope you are doing well. Always nice to hear from you. All the best

Oh man… what fun those are.. thanks for watching

Und jetzt ??? 😉😂😂😂

Hi Drew, sorry I no longer have the special DJI sockets to make the custom harnesses. The 7 pin jst connectors are hard to come by. Most of the ones I had were made from bad TB47-48 packs. Wish I could do more. Sad seeing the end of life for the inspire 1 drones. They are still an awesome platform. Rich

@@RichJ53 Thanks Rich. I will hunt one down, I will take a trip up to Seattle and talk to Progressive RC to find that plug.

@@DJteamster the guys at progressive are awesome. The real problem is getting the socket and pins with ability to crimp these tiny wires. You might make some jumpers and just clip on to the cell that’s high and discharge it by hand. It’s harder but doable.

@@RichJ53 Are you located in Seattle or you just order from Progressive?

@@DJteamster no not in Seattle, but have done business with the progressive boys. Chad can be very helpful. Say hi for me when you drop in.

Thank you for watching! So much fun to fly Rich

I can make one more. Unfortunately, they will not be available after this last one Thanks for your interest. As these drones reach this age, and without OEM support parts will hard to get. If anyone has a bad battery they can use the socket plug to make the adapter harness. Use a multimeter to verify polarity and soldering will be required. I responded to your email Thanks Rich

I can make one more. I responded to you thanks Rich

Hi Steve, yes the turbine ready version comes with pilot branded lights. They can run on a 8.4v Lipo or LiIon power source. Thank you for watching Rich

@@RichJ53 thanks! Left you a message on rcg. Do you have to turn the plane over to access the wing bolts or can you attach the wings and secure from the top? Thanks

@@stevecharrison you can install the screws from the top inside the canopy. I would be a hassle to flip the jet over for this process. I replied back to you in groups thanks Rich

@@RichJ53 makes sense I thought it would be unusual. Thanks Rich!

Yes, I had this trouble too. Did you buy the turbine ready version? I ended up removing the gear and filling up the holes with Hysol. Aligned the gear with the wings on the fuselage, then redrilled the mounts. You might need to trim some of the main gear door frame too. if you need more help; give me your email .....I can send you some photos Rich

@@RichJ53 I just got the 2.2 Viper and noticed the the turbine is mounted from the bottom can you email me a photo of your setup and bottom engine cover, what screws were used to mount the cover.

@@eddiejames8739 Hi Eddie, Sure what is your email? yes the turbine access is from the bottom. It requires drilling 4 holes in the cover, locating one in each corner. They are 1.5mm self tapping screws. I backed up the fiberglass with some plywood triangles to give the screws better purchase. Also, remember orientation of the turbine with the top facing up. This will keep the glow plug in the correct position. Check with your turbine manufacturer recommendation.

@@RichJ53We have several club members from San Diego that fly at our field and you’re welcome to come anytime if you still live in San Diego. Hemet Ca is where I fly, so come up before it’s too hot.

@@eddiejames8739 thank you for the invite it would be awesome, I will do this sometime :) it’s a long drive down I5. I’m not in your area … but hey you never know

Thanks for watching... You never know who's out there 😁 I saw your flameout video, yikes good job saving your jet. What turbine are you running? Rich

@@RichJ53 Yes sir Kingtech 210 great power good performance. Right now I'm doing a completely disassemble for a bearing front and rear replacement. That video coming soon 😇

@@basimpsn wow thats lots of power! You must have a bunch of time on the turbine to be having bearing issues. I have been using Bad Boyz RC turbine oil and really like it. I used Kingtech oil before I switched over. Look forward to you're video. Rich

Hello I am using 12 ch which includes lights of the Powerbox Pioneer with 14 available channels. I would not recommend using Y leads because you will not be able to fine tune the control throws and mixes. If you don't want to control lights the minimum is 11 channels Hope this helps

What about the CG? I am almost get ready

@@GreatXu Thats great to hear. Pilot RC recommends 160- 177mm from the wing root. I started at 177mm then moved it to 170mm. If you are a very experienced pilot, then you can use the 177mm position. or more. I found the jet to start giving me a highspeed stalls at 177-179mm. Hope this helps you ... please let me know when you fly your new jet. Rich

@@RichJ53 Sure , will let you know. Very appreciate to your advice

@@RichJ53 By the way, here is my new Viper ua-cam.com/video/_Q1zCmYhEVA/v-deo.html

@@RichJ53 thank you.

Hi, yes this was the turbine ready version, but was older stock when Pilot RC closed their warehouse in CA. I really think this is a beautiful kit with lots of extras. I had some issues with my jet but this is probably not the standard. The AMG decals were not all applied and Pilot sent them for me to install. The landing gear is very strong however the Pilot gear controller did not want to work correctly for me.. when it was first powered on with the gear doors the sync was off everytime. I decided to upgrade with the Xicoy LGC 15 with gyro. Pilot supplies branded servos PW-20AH (20kg) with aluminum arms. These are made in Taiwan, brushless steel gears by a well known mfg. So far these have been very good for me. The jet flies very well and I can recommend it! The lights are installed at the factory as standard which is a nice touch. This was my second turbine jet and outside of some issues that Pilot RC & Chief Aircraft corrected for me quickly.... it the best one I have owned so far. I hope this helps you, Pilot has made some new improvements on the new viper jet 2M version; 3L fuel tank is one of them. I can highly recommend the SW140 turbine from Bad Boyz RC this turbine is easy to set up and has great power. The Viper can really move out with this turbine but when you want to fly slowly it will do that too. This video doesn't show the slow speed landing but it will do it. I will post another short video showing a slower landing. Let me know if you have any other questions Rich thanks for watching ,,, you can look me up in RCG forum

Hi Yes, I have enough material for a few more harnesses. The socket plugs are removed from bad batteries. I make these custom harness kits to order Provide me your email address for more info

@@RichJ53 Thanks for your prompt reply. I sent you a PM on DJI forum with my email address. I’m also looking for a good but not too expensive balance charger to fix some TB47/48. If you have and any recommendations and instruction I would be most grateful. Everything that uses mains would need to be 230V compatible.

Hi I will check it thanks. Regarding a charger: it needed to have a dedicated balance only circuit. Not a balance charging mode. Only a few chargers have this (icharger-x6)($110) this is the least expensive charger with this feature.

thanks for the feedback buddy

Great Jet!!! 🤙🤙

@@NICHOLASRGLORIOSO Thanks Flyboy. I was so nervous because of some unknown flight settings. So glad to get things sorted out. Rich

@@RichJ53 I KNOW That Feeling for sure!! 😬😬🤣🤣🤣🤣

yes,.... my CG is at factory recommendation. This jet has been very stable in flight. I use 4mm of crow in the ailerons for full flaps. The right wing will drop at the stall no flaps but very softly and recovers well with some speed. Please note, this jets will slow down for landing i.e. full flaps with crow and very solid. hope this helps you

Sorry no links to the DJI socket connector. You might find one on eBay the cones close to fitting. The socket plugs I use on my custom harness are from old DJI dead batteries which fit perfectly. I can make a few more of these custom harness kits. I charge $45 and this includes the custom harness, plus power cables. Add Shipping USPS these are made to order. These are very challenging to make and to get it right. I get a lot of people asking for the cable but apparently they change their minds at the cost. Rich

@@RichJ53 hey you still have the cable for sale

@@mljjones2210 sorry, I no longer have any of the special socket connectors. It would be a lot of work and some battery experience, you could pop off the top and try to discharge the high cell using manual jumpers. It would be difficult but doable. The tiny 7 pin jst connector is very hard to find unfortunately I would have to buy multi thousand of them to place a order from the factory. Not worth it for the occasional requests, plus the inspire 1 is at the end of life because DJI stopped making any parts.

Thank you! !

Yes, provide you email address and I will send you more information

@@dronedays450 email sent... thanks for your interest

Hi, the battery capacity is monitored by the DJI intelligent circuit. I believe this was designed to provide you feedback as the battery is cycled through its normal life. 200 cycles being the end of life. Most people do not get that many but some might get even more. So, the DJI Assistant development software, years ago would let us make some changes to the hardware but it was eventually removed and locked the users out. So based on what I understand, you would not be able to change the capacity in the FW of the battery (locked out) Maybe someone else reading this could inform us more? Rich

Sure I can help. I would need some more info first. Provide email to get more details. Rich

@@RichJ53 sillennium at Gmail

If you get me your email, I would be happy to answer your questions. Please look at the other video on how to get the email to me. Rich thanks for watching

Hi Gbk very happy with the turbine. Easy to start and run. So far no issues and very strong running. I highly recommend Bad Boyz RC for sales and customer service. I own 3 Swiwin turbine motors now.

Hi Stuart, the custom harness is a very nice tool to have to manage your Inspire 1 batteries. But as you know there is no way to guarantee of success in each case. So far most users have been able to fix their batteries, but a few have not. If a cell has been below 3.3v or drained to zero, that's normally a death sentence. I still have enough materials to make the custom kit. provide your email address via DJI forum by PM or here if you want. I will give you more info Rich

@@RichJ53 Thanks for that. You can get me on engineer@lsb.co.nz

@@stuarthayden3381 I responded and hopefully I can help you.

I have not installed the smoke pump into position yet. I have all the plumbing ready and the smoke nozzle in place. The wires will run to my retract battery circuit and aux (ch12) on the receiver. I had the new nav controller but I burned it up :( I am using the Powerbox light box controller (much better) Hope this helps you

My P4P camera was not straight out of the box. I thought the gimbal magnets were messed up from the factory. But after installing the firmware update it was corrected. So, this was a long while ago and certainly other FW updates have happened... It would be hard to say if this will still be the case. You can adjust the camera in the DJI Go 4 app too. Rich

RichJ53 how you can adjust the camera? You can level up the horizon but I don’t think you can straight out that left turn or turn it any direction in DJIGo4 App

@@TAPPChannel .. DJI Go 4 App has the Roll and RAW adjustment but your right the angle is controlled by the hardware and magnets in the gimbal. I was thinking of my Inspire drones... sorry.

@@RichJ53 Not a problem... Maybe firmware update would help something but it didn't helped with the used drone I bought last month... And also I don't want to make those updates because I don't trust them. I want to take it out of the box and fly without any stupid updates. Thats what I've did with my last drone I flew for the 3years

@@TAPPChannel I also have found that firmware updates can work against you. I updated my Mavic Pro 2 and it ruined it for me! I am pretty disappointed with DJI after using many of their Pro drones for 5 years. I hope you get things worked out. Rich

The UAT is 125 which works great. I didn't purge all the air out of it during my test runs and no air was seen in the turbine line. However, I made sure that the UAT had no air before flight. I am using RC Jetwerx batteries two 2200mAh 2 cell and one 3300mAh radio electronics, 3 cell pack for the turbine and 2150mAh for retracts and brakes. Even with everything up front you need to add some nose weight to balance. I would recommend using a 5000mAh 3 cell turbine pack that would help get more weight up front.

RichJ53 awesome that’s good to know I was gonna use 4000mah receiver packs but maybe I’ll use 5000 pack for turbine like you said and I had gotten the 250 UAT tank but will probably order a new 120 one instead and now I’m just waiting on my receiver

thanks for your interest and please report back how your battery repair goes! Everybody can learn from your experiences too Rich

Hi I was wondering if this harness are still available? Have some Batts with unbalanced cells I would like to fix.

You will be very happy with the turbine please post your thoughts after you receive it. what jet are you powering?

RichJ53 the same jet hsd mb339 getting ready to buy the ix20 and the receiver as well

-The IX20 is a awesome radio, I did a review on Horizons website. The MB339 flies great with no bad habits. I am very happy with the jet and power combo. You should be very happy keep us posted on your progress Rich

Hi Randy and thanks... I think the SW120 really makes this jet fun, and you can fly around on reduced power to save fuel if required. I am having some trouble learning the brakes on this thing. They are all on or all off which causes me to over control the nose steering as well. I might buy the Xicoy ABS brake unit to give me a hand but so far, I am still trying to do the braking manually :)

As long as all the cells are over 3v and they haven’t discharged to zero. If they do, it will damage LiPo cells and they can’t be trusted to come back or the internal resistance becomes to high for them to take a charge.

@@RichJ53 Hi Rich Thank you for your answer. So what do you advise me to do ???

DroneXfly DroneXfly Can you provide some screen shots of the batteries connected to your DJI App showing their status? Or provide me your email and send the photos to me for review

@@RichJ53 , ok i write on PM (Private message) on the DJI website

DroneXfly DroneXfly I responded Thanks

Hi Glenn I sent you an email. please share your battery issues for others to see on this post. Its nice to share with everyone and becomes helpful :)

Hi Aaron. Thank you for the kind words. Please keep In mind that LiPo batteries don’t like be under the 3.3v per cell or low charge for long periods of time. This and other factors can damage the battery beyond repair however each case should be considered fully. As the internal resistance increases it becomes less likely to accept a full charge. At that point you need to decide if the battery can be fixed. Send me a PM on the DJI forum and I will try to help. I do not have a wiring diagram available at this time. The balance socket can be soldered to a std balance cable such as my video. You can use a volt meter to find the polarity. Take a lot of care for safety reasons. :)

Yes I can still provide one of these harness kits. There are several chargers that can work fine ISDT T8, iCharger X8 or X6 but all of these require a power supply.

Okay 👍

Hi, I do not believe there are new solutions regarding the T47 / 48 DJI batteries. DJI would you ratter buy new replacements instead of fix the old ones. You do need to have some basic understanding of the LiPo battery chargers and how to use them for safety reasons. This is a good way to fix or manage batteries that still have good cells. This will not really help you with batteries that have been sitting around with zero power or dead cells. Hope this helps youRich

Unfortunately DJI stopped delivering these batteries (no replacement available). So I have a choice: look for a solution or end of my hobby ☺️. The batteries have a low usage, but the cells are not balanced 🥴 I have no idea how to fix the unbalance without your solution... I know the support had ended, but I don’t want to stop flying right now ☺️.

So, if you want to recover your batteries with a little learning. most new LiPo chargers are pretty easy to use. I can still make one of my special harnesses for you and provide all the supporting information to get you going. You need to PM me on the DJI forum group or post your email address. Let me know if you are interested.
