RE: 90 sized engine recommendation
Bigdan: complete agree. The only reason i went for a $280 dollar OS engine was because of the $60 off discount at Tower. Plus I sold some other stuff on craigslist (old engine, my nexstar trainer, etc) to help offset the cost. I haven't made the jump to 2.4 yet. I'm still using my Hitec Focus 6 FM radio with the standard servos that I bought 10 years ago! And you know what? It still works great. I love the radio even though the only features on it are rate adjustments and servo reversing.
