cAN YOU USE A NEWER 10.5 MOTOR WITH THE SPEED CONTROL THAT CAME WITH THIS ORIGINALLY? LMK Thanks

Yes you can. The new 10.5 is essentially the same motor as the original 4300, it just comes with the upgrades installed.

What was/is this 4300 motor supposed to be like a 19 turn brushed or a fast stock motor? :confused:

Like I said the 4300 and the 10.5 are the same motor, just a different name.

It is a little bit faster than a 19T.

as Pat said, the 10.5(4300) is usually just a tick FASTER than most of the 19t's...on MOST tracks.

We've seen a couple tracks where the 19t's are still faster (Mainly because they guys running it had a GREAT setup...and havnen't found it yet w/ a 10.5 (4300)

The difference between a 13.5 and a 10.5 is pretty small - and I'd have to say a GOOD 19t falls right inbetween the 2. POWER wise. (The RPM's are quite different)

On our flat asphalt tracks down here in Florida 13.5 looks to be about .2 a lap slower than 19t and 10.5 and .1-.2 faster than the best Stock times.
I REALLY like 13.5 4-cell :)
