See if you can remove the dummy missiles as well Dom. That will be causing a lot of drag on the aircraft due to the cartoon dimensions of the ordinance. Great flight, nice recovery.
Agreed terry. That's a good guess of 1/8" I think. The usual Fan Swept Area (FSA) of the intake is the area of the diameter of the inlet, minus the area of the motor's diameter. The exhaust usually gives the best thrust with an area of 85-95% of the inlet's FSA. The thrust tube outlet diameter is always a narrower exhaust diameter than the FSA of the EDF by that difference of 5 to 15% of inlet and outlet FSA.
Good flying! I think a lighter pack would be better for the hand launch too. I added a front skid to my mine to keep the nose up during belly landings and I can keep the TCS Chin pod on the nose. Tried to take off from the grass with the nose skid but can't get enough speed on our lump grass RC field.
Don't know unless I try. Flies OK on 4S2700 as is. It might help a little but it's never going to be that fast. It's very fat and draggy. Watch the next vid (currently available to Members) and see what you think...
Well...pusher is a valid power system although a bit dated. Twin EDF sounds much better. Wait until you see it on a 4S2700 pack. Transformed it. We couldn't believe how slow it would fly.
You might want to consider trying 2 4s 2200 mAh packs and see if that gives additional power. Have it so that way each ESC has its own individual battery. That might just increase the power quite a bit.
Might want to open up the intakes as they’re very narrow. That’ll allow for greater airflow to the ducted fans. Leave the weapons on though. Can’t have an unarmed F-14 flying around. Turn and burn baby!!
I like it much better with the Dual EDF Units. I wish they would increase the Wingspan a bit for better stability. Great job keeping it in the air. I think the TX Sticks get a workout with this one ;-) See you in the Air!
Thanks for sharing! I was watching some other cartoon plane, and the algorithm took me to your channel. It looks like there's plenty of room in there. I wonder if I can 3D print an EDF support to house a 70mm or even a 90mm!!! I noticed that you didn't place the ESCs to where they get cooled by the air flow? I hope they don't over heat on you.
Nice video! Do you have more footage of the planes conversion it's self? I have the conversion kit for NIB Fatty but I am hesitant to start cutting away on a new plane with no knowledge of where to cut. I'm also not sure what to use to make the cuts. Is it a razer blade or a saw? How deep did you cut, etc. etc.?Thanks.
When that thing launched it acted just like a fatty . Took it's time to gain airspeed . LOL So here is my score board . Takeoff 10 , high speed pass 5 to fast of a fatty , Scale turns 7 , landing 10 and nailed it . Total score 32 out of possable 40 . Not bad
@@EssentialRC Got it. It was never clear to me on the proper way to hook up multi-ESC models. I keep hearing conflicting information on forums like RCGroups. But it seems to be working fine for you.
I think the intakes openings need shaving open bigger and/or at least chamfered somewhat, as they currently are quite thick & flat on the edges - although that does provide some model resilience/toughness, and seem to me, too 'small' at lower speeds, without as much ram air into them for the motors/fans potential. Also, your exhaust ducts might be slightly mis-aligned if you have trimming (drift/rolling/skidding yaw) issues higher speeds. But considering the bulbousness. it fliees better than you/I think it should! Well done !! :-P ;-)
to bad the Pilots ejected to late, hope they are ok though. Anyway, yes looks like a 4000mah is to heavy, hope to see another fly soon from you with a lighter pack to see how it will handle then

Will do for next flight !
Great idea
I don't think it will make a very big difference as their shape is fairly streamlined and they're not too terribly large
Also thank you for sharing the build with us. I was considering getting this plane and converting it over to EDF.
Well, it flies like a cup and saucer, but it's very cool.
Looked a little underpowered on the take off and could definitely use a stabilizer. Otherwise it is a tremendous success. Well done.
Great upgrade Dom, love the thrust tubes. I guess the wind got you on the landing. 👍🏻
More the weight of it. Relatively high stall speed. Using a lighter pack yesterday made it very easy to land smoothly.
Good job on the conversion, you may gain some more thrust if you make the end of the thrust tube like 1/8" smaller all the way around.

HI DOM GREAT IDEA SEEMED LITTLE UNDER POWERED.
THANKS FOR POSTING SIR 🇬🇧👍🏼
Yo MIKE!
@@jonoedwards4195 GOOD MORNING JONO 🇦🇺✌🏼
Just too heavy Mike. Flight yesterday on 4S2700 was awesome
@@EssentialRC BRILLIANT 🇬🇧👍🏼

Good tip! Will consider that myself. I fly off grass and don't really want to shave the paint and foam off with each landing.
very cool
Really good
what a fun and funny looking edf... I might have to get one!
And that's why I like it 👌
Always entertaining Dom! So other than a lighter pack do you think it may need cheater holes/louvers for more intake?

NIIIIIIIIIIIICE conversion! 😁👍

Cue the mini turbine install …. 😂
Henke is doing that on rcgroups

It would be way too heavy with combined 4S4400. It was bad enough on this flight with 4S4000. Watch my latest vid with 4S2700. Flies so much better.
@@EssentialRC Maybe two 62mm fans might work. Would be an interesting and fun video.

There are already big holes in the side letting in more air than you can see through that front intake.
Request:
Takeoff test?

It's certainly a challenge to fly...but I like that 😆

This is a very good idea 👍
Glad you think so!
コア・ファイターも飛ぶかもしれないな
Looking at the inlet size I think the EDFs are a little starved for air, maybe a couple of cheat holes would help them breathe better.
Possible. Will see what I can do about that

I'll take that. Thanks 👍
When you Y-harness the two ESCs, it is required to disable one of the BEC?
Didn't even occur to me that I might need to. I just Y leaded the throttle cables together. Worked for me.

@@EssentialRC it probably doesn’t matter since it’s in parallel I think
Looks quite underpowered to me how about making your own conversion 3D prints and put in 2x 64mm edfs? I think that would help alot too!
This was first flight after the conversion. Much better with a lighter flight pack in later videos
Obviously the EDF conversion is
much nicer than the pusher. ^^
Nicer but less powerful

I flew it on 4S2700 yesterday and it was amazing! Jason also got some air to air with his drone. Will upload that later today
@@EssentialRC sounds good, can't wait to see, how was flight time with the 2700?
~3 minutes with very gentle throttle use. I was at 50% for most of the flight. Full throttle on downwind passes didn't really make it go much faster.
