Trebor,
Looks like I can use the alloy plate I'm already using - has twin mount holes, and as the throttle / brake servo position is angled, it also looks like I can get the throw in without problem.
I've got the same 'horn' as you have. I'm using a Savox 1256TG, so force is not a problem.
I'm going to try out Hobbythek's 'direct power' cabling to see if there's any difference, particularly with the twin Rhino set-up.
I like the use of double collets. I've just gone down this avenue with my LST2 Raminator clone. I was fed-up of having more-than enough power, just for the collet to slip. Solved the problem immediately.
Wife's away for another day or so, with our lad (3 year old TOO inquisitive!!) which is permitting me to get some 'jobs' out of the way.
Alan.
