Hello,

I have a set of plans for a T-28 Trojan. Upon receiving these plans I realized that they were for a control line version of this plane. Would it be possible to convert this particular plane into a standard R/C aircraft that would fly untethered? Of course there are some reinforcements and control line attachment features that I could dispense with but as far as aerodynamics, would it most likely work? I would really love to see this thing fly on it's own. Thank you for your help.

I have flown several models as RC or CL with a 5 minute conversion from one mode to another. The only difference between the two types of models are the following;

1) CL model has wing tip weight
2) Bellcrank instead of elevator servo

All should have to do is remove the bellcrank and associated structure
Make sure the airplane is balanced side to side (left wing is weighs the same as the right)
Fin should straight, and of course install a servo to move the rudder

C.G. on most CL models tend to be more forward than RC, generally I follow the 25% of the average chord for the CG location, then maybe move it back to the 33% mark if you want more repsonse.

Also look to see what engine offset it has, sometimes they put right engine thrust (outboard for CL), remove that if you don't want that. The real T-28 has down thrust so the plans might show that.

Good luck,

Are those plans free or commercial? If free could you send me a scan or sth like that?

TIA
