I need some help. I’ve driven the mp9 nitro buggies for a while now so I decided to get an MP9e TKI4. The electric version seems to want to nosedive most of the time over jumps with a little size to them. Sometimes it’s incorrectable. The nose won’t pop back up like a nitro buggy. I’ve messed with the shocks some with very little success.

Front shocks: Kit shocks w/ gray springs and 550 Kyosho oil w/ about 1/8 rebound.
Rear shocks: Kit shocks w/ blue springs and 400 Kyosho oil w/ about 1/4-3/8 rebound.

Could it it be the stock body I’m running?

The car is great otherwise!

The stock tki4 I recall comes with a 12 tooth pinion which I feel is way too small for a brushless motor. That low gear would create a good amount of drag off throttle. I’d look at increasing the pinion to 14.

Thanks for the advice. I’m running a 13t now, but will try the 14t. Also, is the stock body very sensitive to where holes are reamed? I need to let my car breathe so the motor can run a little cooler. It’s about 180* after an 8-10 minute run here in north FL.

I’ve got holes in mine at the front and I don’t feel it makes any difference, I think most guys drill holes regardless of make. The Electric body is bigger to fit the batteries. I know tebo slices the battery tray to lower the batteries so he can fit the standard nitro shell - there new LCG batteries coming out which are smaller so you don’t have to do that. I’ve got both shells so will make some closer observations when next out ��

Running the higher pinion may help the temps too. I suspect you’re revving the life out of your motor... I’ve seen pinions as high as 17 on this buggy.

Thanks for the info. I’ve got a race Saturday, so I’ll try a 14t and 15t possibly. I won’t worry about cutting up the body yet. Ordered a couple of Yokomo fans and a mount for them. Will try them if I can’t get the temps lower with gearing. Gotta do some testing after the race. Wanna try 17.5* hubs, emulsion shocks, and flipping the upper hingepin bushing. Just got back into racing after a few years off. My last buggy was a tki3 nitro.
