I would look at a Thunder Tiger 46 first, I got a Tower 46 for my brother as a birthday gift and had all the problems but another had one at my club and have had no trouble so it's pot luck getting a good one, TT is a better chance of getting a good engine for the same price and not too many problems and this is comeing from a OS guy but OS 46FX is about $45 more and just noticed the Thunder Tiger is $5 cheaper than the Tower engine. http://www2.towerhobbies.com/cgi-bin...1&I=LXKF97&P=0
