Default T4 Slower Than Normal

Hi guys, ran my t4 today and noticed that it is running alot slower than normal. I have a mamba 6900 combo and running 4200 intellects which my charger has put 4600mah into. so i dont think it is the battreys. Just wondering why it is doing this, and what could i do to make it run quicker. Gearin is 87/17. also should my t4 wheelie with this sorta of power/gearing as i cant get it to wheelie at all.

cheers

alex

Might be a dumb question but have you checked that the radio throttle is turned up as well?

Check the voltage in the individual cells, check the settings on your radio. Also check that your rear diff is not slipping, and check the tightness of the rear wheels.

The last race I entered the rear nut came loose on one of the wheels, and it was just enough for the rim to get away from the axle pin. The pin spun and stripped out the back of the rim, so when I gave it throttle the axle spun in the rim causing the tire not to turn.

Though the later can be a rare occasion, its worth looking at.

If it's running at a slower top speed and not making any weird crunching or grinding noises it's pretty much going to be the batteries. Can you borrow another pack to check?

That is all good advice, I will add; check your cvd's to make sure none of the axle pins are broke. Also your slipper, however this is probably the least likely of the occurrences. But I would guess that either the t-nut on the diff is wore out and your diff is slipping, or a cvd pin is broke.

I don't know anything about the Mamba setup, but with an 87/17 gearing, I would guess you smoked your motor or overheated the ESC or both. I was helping a guy dial in his T4 yesterday, and in the end we had him at 81/25 with a 13.5T X-11...AND HE WAS FLAT FLYING!!!!! But with that gearing, you have to be getting incredibly hot.

thanks guys, i have checked all of that and i think i may have found the culperate, in my wheel where it bolts onto the rear you have the pin slot in the wheel well they left one has molded over on its self. so that could be it and also the reason it was gettin to hot.
