SKY-JIVES:

WHY NOT TRY TO MOVE UP IN PHASES, If your are in the 40īs climb to 90īs and then to 1/4, maybe even jump to 120 4-s with a extra 300 from golberg, what about an ultimate biplane, place an OS 91FX and then a YS 120 or 140 and finally to a 1/4 scale, you even can put the YS 140 on your first one, after that you can try your first gas engine.

just my tip!
