I have a MVVS .77 and a .49. Have ran the .49 in a Balsa Nova using the optional mini tuned pipe. Pulled the model around really well withgreat vertical using a 12x4 or 12.25x3.75 APC's. The .77 is installed in a TF Corsair. More then adequate power. Using a bisson Pitts muffler and installed two head shims for the 10% nitro that I run in my other two strokes.
Good quality engines. There Quicky .40 has a good reputation on the race curcuit.
