best second plane
the reason i always go the stick option is they are so versatile, an easy transition from a trainer and easy to build, one of mine (SPAD DPS) is like grandads axe.
it started life as a standard 40 size stick with a flat bottom wing, then i built a fully symetrical wing for better inverted, then i built another symetrical wing with 3" ailerons and 2 wing servos, then i built a new fuzz 3" longer with bigger control surfaces and used the 2 servo wing on it and went from a 40FP to a TS46.
and my next one is going to be a low wing stick probably using the original flat bottom wing, all from the same basic plans.
As i said this was a SPAD but theres no reason you cant do the same with a set of balsa stick plans.
not only that sticks are easy to scratch build from plans.
oh and there CHEAP so its not a big disaster if you bounce it practicing.
