wow i thought i was addicted to them i have saitos on 5 of my 8 planes and not a one has ever given me a fit and i know the saito 56 i have on my kadet senior has some serious flying time on it and its still going strong and the easiest starting motor i own lol.....well anyway like i said earlier post you cant really ever go wrong with a sig plane or a saito motor ive flown great planes planes and tower hobbies planes and they just dont perform like sig ive recently bought a couple of kange planes and ive been seriously impressed with them so far id almost put them on the same pedistal as i do sig..........but for a second plane man a 4 star is really hard to beat
