- 3 minutes into the flight I lost all power to the EDF. Thankfully the lipos were good to the receiver giving me the opportunity to carry out a dead stick landing. I decided not to deploy the retracts which would cause drag. The speed looked good down wind but the speed soon bled of on the shallow base leg turn. Just as the viper looked like it would make it through into wind she leveled out and continued on the base leg track narrowly missing a hedge.
Early indications find a crackling sound within the positive spark arresting AS150 connector. The ESC can't be armed and only a crackling sound can be heard in the positive AS150 connector.
Sorry for your loss!
Sorry about you damage. I stalled mine on flight # 2 and they are repairable.
Well that sucks. My HSD Jets are 3 minute flights, period. I have lost power on brand new batteries at 3 minutes. I fly 5000-6000mah. Some 5000's are better then others. My Liperions handle 3 minutes just fine. 12s setups can just empty batteries really fast. I watched this video because i am thinking about purchasing this jet. Thanks for posting.
Maybe I received a faulty model however the feed back I had indicates more to the thrust outlet dimensions than the any other issues. I was achieving 363w/ld on the stock setup on ground tests, so cant imagine it was lipo's or internal electrical issues rather the air not efficiently leaving the EDF/thrust tube.
@@All_things_RC. well…this jet has a lot of successful flights on it, if you are questioning the engineering….. Although you may have a reasonable battery reading on the ground after the flight, you just don’t know what the batteries were putting out under stress. Anyway, enough of that crap. Onward and upward. Just received the HSD ME-262, let’s see how she does……
My on board telematry showed a 10% reduction to the performance figures between static and when she was flying. Good luck with the ME.
So sorry Pete hope it's repairable.
Thanks Keith I have already started to repair, I put some carbon strengthening rods in the air frame and glass cloth over the area? I hope this will be enough because the retract is at the front therefore beyond the break point. I am confident in the repair but I will have to be careful not to add too much weight especial when the model is already under powered.
Sorry for the loss, I wonder if hsd will cover it? Let’s hope so
I am in touch with them now I will inform everyone of the out come on my channel. My best scenario will be to to prevent others having the same issues if the is an inherent fault
Sorry for your crash. FYI for all...in todays RC world there is little reason not to have the battery voltage known to the pilot at all times. One easy way for under $100 and can be moved from plane to plane is to get a FPV camera ($30) mounted on the aircraft (you can just attach it inside the fuselage..doesnt need mounted outside) that shows the main battery voltage. That signal can be received by a cheap pair of goggles or a small 6"-12" monitor mounted on a tripod next to the pilot. There are other ways also. (telemetry(voltage) can be sent to your radio, displayed on a screen and then the value announced every 15, 30, or 45 seconds). I use the camera with voltage display and NEVER need to worry about what voltage i have left.
Thanks for your contact. I fly all my models with on board telemetry giving me constant audible and live Volts, watts, Amps, height, speed, and time flown. All this data only confirmed the lack of thrust from the EDF unit through the thrust tube. At 320W/ld in flight the electrical set up was sufficient. A static thrust test only gave 4kg of thrust for a 5.5kg aircraft?
@RC Pilot Pete Watson wow 4kg of thrust isn't much for a 105mm 12s system. I get that from 90mm on 8s.
LOL TRIPOD?
What I like from Horizon Hobby and MotionRC they review you video and make a determination, and in most cases they replace the airplane.
I agree but in the case of HSD it seems not their way. Having said that I have never had any issues with my Freewing models. maybe some morals lies in this story.
Ohhhh no, désolé pour ton soucis mec :(
Flying it alot of wind there... Even though your flight time on the watch was 3 min which should be within charge, having to fight that wind probably was more like a 4 plus minute flight so no battery left. Maybe your wind conditions are normally high in that area but there's a reason why I won't fly in gusty winds, I ain't that good.
The wind was 15mph so not too much for an EDF of this size? My normal flight time is 4 minutes with 25% left in the lipo. This was not the lipo going flat but an issue with the ESC failing. I no longer have the model as the last crash was terminal through low thrust. My investigations found the outlet pipe in the moulding of the EPO was only 1mm smaller than the diameter of the fan thus not creating enough thrust.
Ok this is manufacture electronics fault and the HSD should be responsible to replace the plane free of charge, because this is not pilot error is manufacture fail, in this time of the game is not excuse to install garbage electronics with the price we pay. sorry my friend.
Thank you. 14 days have passed since I sent the link and complained to the distributor and HSD, still n reply?
This is a high end high value item at least a reply would be nice!
