RE: Minor kit bashing on a TF Contender.
Agreed; build it as intended.
In the first place, there isn't a whole lot of room in the empennage. In the second, you'd really screw up the balance by putting servos back there. Mine had a 70 Surpass, and it balanced perfectly with the battery under the flap.
You should be more concerned with the wingtips. Built flat, they give the model pitch/roll coupling when rudder is input. The "reverse Horner" (upswept) tip mod shown in the manual eliminates this, and makes a better flying model.
Mine died an early death, through no fault of the model. It was one of the most fun planes to fly I've ever owned; that ventral flap provides another entire dimension to low-speed flight, and I would already have another one if it wasn't such a PITA to build and cover.
I plan to build another after I retire and have more time. I just hope the wood is a bit better in that kit... the last three GP kits I've done had crap wood.
