I just bought the jetcat p20 that was listed here, wanted to know if someone has a

HET F-20 tigershark here that can give me the measurements in the back where the 70mm edf unit goes. I want to see if I can put the p20 turbine inside of it. HERE is the link to the JETcat P20 specs. I can point the kero plug toward the rudder area. THIS would be super cool jet as a turbine. I use to have one and use to handlaunch it.

IF it does not pan out with the F-100 I want to try it into this. SO if there are guys out there that own this please tell me the measurements i want to see if i can get this in there.

Yeah, I guess I should say it now, You want to the 90MM F-20 for that instead of the 70MM F-20

I would stay away from the Het F20 unless you want a ball of smoldering splinters. It's made for a very light EDF setup. Mine broke apart in mid-air when I put a larger lipo in.

The air sally version is probably the minimum you will need.

Yep...


Generally, you want a 90mm airframe over a 70mm... just so you have enough wing area to support the weight of the engine, and fuel.

The P20 will fit in any 70mm airframe with more room to spare then a edf set up. You just need to be able to get fuel in near the CG which is the hard part

okay so i put into fly fly F-100 here is some pics

I just have to figure out where to put the tank. I wanted to put where the battery goes but I need part of the tank behind the cg so will have to figure something out. I just did a simple cuts that will be covered with the tail cone and will cut and sand down the tiny wood sticking out after the hysol dries. I flew it with 6s 4400mah 12 blade 1500kv motor it was good but very short flight.
