F-4 Phantom Conversion, HELP!!
I know that there is a lot of great knowledge/experience on this forum. I need help/suggestions for converting my CJM F-4 Phantom from twin d/f to turbine power. The plane is built and was almost ready to fly with 2x91 d/f engines. The previous owner sold the engines and I bought the airframe seperately. I am leaning towards a turbine in the 25-27# class with a Tam bifurcating tailpipe. I have talked to CJM and they have a tailcone upgrade from the ABS ones on the d/f version. However since this is the older, one piece wing, the brackets for the Elevators are made of nylon/plastic. I don't think they will hold up to the stresses that a turbine will put on the control surfaces. I have Hitec high output digital servos for all the control surfaces.
My questons are:
1) Which turbine will give me the best performance and reliability? (I know this question could open a whole can of worms)
2) Any suggestions for the torque brackets on the Elevators? The old ones look like the mounting bracket off of a .60 size nose wheel.
3) The full-size F-4 had its engine mounted with about 10 degrees of down thrust. Is that necessary for the model?
4) I know that I have to change the formers to suit the tailpipe and turbine. Any suggestions with the ease of retrofitting and maintenace in mind?
5) I have seen several threads on the behavior of the BVM F-4. Does anyone have any feed back/experience with the CJM F-4?
6) One of the threads I read pertained to the AoA while on the ground. I have noticed from all the pics of the BVM F-4 that the nose wheel strut is longer than the CJM. The CJM sits with a neutral or slightly negative AoA. Do I need to adjust this or will the plane rotate gently? The F-4 mains are well back of the CG.
Thanks in advance for your feed back.
