Silverback Gorillamaxx Build

[Rivermaxx]

Have you ever seen integy on any of my nitro trucks lito. I learned a long time ago not too touch that stuff. It sounds like the short duh tower wont work too good so UE knucklehead it is. I just thought keeping everything low cog woulnt hurt.
Suspension now: rpm true track(need too buy)@~$80 or UE widetrack (I have allready) or racer x with setbacks if I can find them for ~$350 (need too buy) or UE ext set up(need too buy)~$150 used for 15mm version. What do you guys think ? The only down fall to rpm is I would have to buy 3.3 spec cvds because I dont think the plastic sliders will hold up.But I have a couple sets of UE cvds in my stock.
I almost forgot steering 1 hitech high torque servo or two hitech 645?
