I can only imagine what the 2.10 must be like. What were you flying it in? I suppose the 61 must be nice and potent for 50-60'' span models?
I had my 2.10 in a great planes patty wagstaff extra 300. i bought it ready to fly but it was a great set up. the engine, once it's wet, starts on 1 -2 backflips. it is the best sounding 2 stroke i've ever heard and is tremendously powerful. it will take a 15 lb plane straight up with authority.
