Re: RE: receiver question 1: powering [TANKS]

Thanks Steve.  The motor is the 18rpm surplus center motor (Frank has the 6rpm 
version and the 2rpm version is up top for the elevate).  Its hooked up to a 4" dia 
wheel 4" away from center so it gets about 8rpm.

What led you away from this type of design?  I'm still in the early stages of 
development and given my build history its very likely that I'll redo it a few times 
- I only need a half decent reason to rebuild :(
