Thought I would share a few mods and results.
I installed low profile servos up fromt,moved the trans and motor assy forward put a rc4wd 4:1 reduction unit ,3 rc4wd driveshafts with a center carrier bearing, rc4wd locker spool in the rear rear diff and left the front open. Moved my 5th wheel a scale foot forward of the tandem center line , cut the axel stops off so the rears articulate better, new tires with on/off road tread... and what a difference it made in the off road.
It steers better with more weight up front and the 5th wheel placement. Climbs over 1-1/2" bumps with ease, and can drag a trailer around with great traction..
Before all these mods this thing would get stuck on a little gap in the ground.not anymore!
Some of these mods were noted from members here just wanted to say thanks and glad I joined this forum...it's been a big help and glad to be back in this hobby...
