Hi Roel
I've been playing with my mo5 for a while and getting it dialed into our local low traction carpet track.
With my mo5 (m) I run
yellow front, red rear springs,
550cst much more oil all round,
1.1mm 3hole pistons all round
ackerman, rear hole on steering,
zero toe front,
1.5deg rear toe,
zero front camber,
2.5deg rear camber,
lowest ride height you can get away with, mine is 3mm all round
modded rear wishbones to bring wheelbase to 227.5mm (way better than STD)
HPI Saturn 15t motor
MRT mx pro esc
KO servo,
yeah racing lipo, w/70gramms lead under and around the servo
Tamiya S grips with kit inserts
swift shell...
Absolutely dialed....
I cab show any pics of the car as it's been donered for my Xevo converstion. But I'll get some pics of the rear wishbone mod. This was the biggest difference we found, assuming your club allows this it's worth a try,
Hope this helps
Luke
