RE: First Warbird??
TF 60 sized P-47. My first warbird (see my gallery) was this kit with a 1.20 four stroke which is overpowered. A .91-1.00 four stroke would probably be perfect. Use all the extras like flaps and landing gear. Model builds easily and is a blast to fly and really slows down nice for landing using the flaps.
Build it! You'll be glad you did!!
