A/Pnuts, I am going with the trike setup. I am looking around for the right sized nose strut for a more scale look. There are a few available but I don't know if they are worth the bucks. I am not that fanatical about scale when it takes 100 bucks for a fixed strut.
You could convert this to conventional gear. Piper just turned the gear around on a Vagabond/Pacer to get the trike. You would have to add a block or ply sheet the rear to mount a tail wheel. The plans show a tail dragger mod and there may be a tailwheel mount in the kit. I have not looked for it because there was never any question as to gear chioce.

As to a removable Radio Compartment, it could be removable with a little inginuity. The plans show a box that contains the servo tray battery and Rcvr that is glued in. I talked to the factory about it and several suggestions were talked about. It is a neat set up, and with a little thought you can make it pretty nearly "removeable" Down load the manual from Mosquitobite and you will see what I mean.
