The 20, 25, 35, and 40 FPs all use the same NVA.  It also fits the 25/40/46LA without drilling.  Tower has them, http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXCR49&P=ML

Except that you have to drill out the crankcase and venturi for themm to fit.

A minor inconvenience, while allowing the use of a variety of much better NV Assy's.  I don't like "clickers" and especially don't like OS NV Assy's.  Randy Aero's are my favorite.  He might even have a size that fits without drilling, since he has one to fit Fox .35's.  H^^ Steve
