4c
Istarted in this hobby about 18 months ago and I went throught the usual 2C engines then I bought a used Saito 80 and I fell in love.The sound and reliability are awesome. I fly an OS52 in my great planes Cub ARF and it's perfect. It's so realistic on slow fly-bys I sometimes forget I'm flying and just watch it go by. An OS52 in an LT-40 would be perfect. No more 2C for me.
