RE: Airtronics / Sanwa MX3 FM 3 CH Radio Swap Program
Oh man, that sounds like all kinds of fun. Well, I don't have any immediate fix but I do have some info. The part number on the 11t pinion alone (which was actually quite difficult for me to find...and I work here) is FF034. These parts can be ordered online at Toyhaus.com and rcmodels.com but they are not listed on their sites. I am being told that it is possible to call them (I would try toyhaus personally) and let them know what you need and that they can order it for you. I know its an expensive call but you could then order a bunch and be done with it for awhile.
