I'm flying a Tower Hobbies .60 Trainer ARF. It's a MkII that I got on clearance sale when they were switching to the MkIII, it was less than the .40 ARF. I powered it with a Magnum 2 stroke .60. This has been a very good engine for me, I just keep the glow plug battery in my back pocket when I'm flying-the engine typically starts within 2 flips by hand. The plane flies well according to all experienced pilots that have flown it in the process of helping me learn, personally I think it flies GREAT but I am just back into the hobby myself. I just picked up a spare landing gear set for about $9 delivered from Tower. Hope this helps.
