Help keeping my Super Nitro on the road!

[PerfectTechs]

Hello, I'm working with an HPI Super Nitro RS4, its a 290mm car. Did some upgrading and I can't stay on the street. Heres my setup.

OS .18 Engine
OFNA 2 Speed Transmission
90wt Shock oil
35mm HPI Racing slicks
350 z body with big wing
Slight negative camber on front and rear
Slight tow in on rear

The car shifts into second gear around 65 and flips backwards at around 75 but it still has much more to go, any ideas? Thanks in advance!

What kind of tires? If they are rubber they may be ballooning. Try some foams.

I don't know if it would actually work but we have the same problem with ours. We're planning to carve out a section in the front bumper and but like a one or two ounce weight in the part we carved out. In theory it should help keep the front end down and even improve steering. Also you can add or remove weight depending on if you need more or less. We have the Hpi Super Nitro kit version with Hitec servos and an O.S. 18 Turbo plug. This thing is wickedly fast if you can keep it straight..:LoL:
