Hi,

I have one strange problem with my 27Mhz Rc car.

When i pick it up, Its rear wheels turns very fast by making throttle from Tx.

But as i put it on ground it wont run / it goes very very very slowly to move further, Even New Battery is fully charged.

Even I have changed Dc Motor, New Battery.

Also checked gears for slips.

From my side everything is Okey.

But cant understand what to do?

Pls Help!!

Thanks

@ronak,

Looks like rpm too high and torque too low at the wheels.
Like trying to get a real car moving from standstill in fifth gear.
Try giving it a push, may run after getting initial acceleration from push.
What you probably need is a lower gearing or a lower kv motor of same wattage.
Best wishes.
