Make it a tail-dragger, 90% of your airplane problems will be because of the nose wheel. You want to mount the main gear for the tail-dragger just in front of the bulkhead at the leading edge of the wing. The nose is also MUCH stronger if you put your tank in, make sure everything is good, i.e. no crimped fuel lines, then glue the hatch on. My hatch has been glued on for 3 years now, no problems. To make the tail wheel all you need is an 1/8 inch music wire, fender washer, and a wheel coller. You have to do it before you glue the fin on.

I'm a engine nut so I've had lots of motors on it just for fun, they are:
TT.40
Tower .40
MDS.38
Testers .35
OS.40fp
OS40LA
ASP. 46
TT. 46
Saito .40
Saito .45
Saito .50
VT.49
RCV.58
OS.60

Maybe a few others, I think up to 14 engines. My favorite engine for it was the Saito .50 and Tower .40. Most guys over power the plane and fly it too fast. With modest power at slow speed it's a Great plane, over powered going fast it's a good plane. With the OS.60 & RCV.58 you have to add a lot of lead to the tail, 3~5 oz., but with the .60 takeoff is 10 feet followed by a 80* climb out.
