If you plan on having an RC engine converted for CL be very careful on who you send it to. I sent one to a well known engine person over a year ago and I do not know if I will ever see it again.
There never were a great many engine models that performed the "Classic Stunt" type of run, usually referred to as the "4-2-4". There always were a few stunt pilots choosing other engines instead, and doing well enough.
Thus, there ahould be no need to "send away" most engines to have anything done to them. Just buy the right size intake venturi fitting, and a good NVA, install them, and go flying! If you want a 4-2-4, buy the right engine in the first place, otherwise run it just the way it was designed. The classic run is rapidly losing favor the last few years. It's somewhat cyclical, so now that the Brodak 40 is out, maybe it will go the other way for awhile.
