Thanks for the info.
I am building two planes, just because I always wanted to build a carrier plane. Neither will have a slider. One will have flaps the other one won't. Both will use out of the box r/c engine.
I have several old, but new in the box, Taffinder tanks ( showing my age) one is a 6 oz that I can cut down to size.
Thanks again, that gives me a starting point.
