The arms look the same, but they can't break just by looking at them anymore.lol

They can take a pretty darn good hit!

You're not going to beat Bill Sydor by testing the strength of the arms

the trick to beating bill sydor is to tuck his light weight body and keep going without looking back. you will see his forhead turn red and at that time he will be so man he will blowout every lap trying to run you down after the third or fourth blowout he will have broken his car

No, but with a 13.5 anything is possible.

The problem with that is he knows how to stop on the track and wait for you to come back around. Then he is pretty good at point and shoot.lol

Default dyno numbers

Im sure that this topic has come up before but...I cant find it so here goes

Motor dyno numbers and understanding them

I have 2 motors CO27 and Hellfire RC24

CO27 numbers are listed at 5.0V
RPM 21,926
Power 57W @10.6K
Eff 43.9% @ 14.5K
Torque 89.1Nmm

Hellfire RC24 at 7.2V
RPM 26989
Power Max 114W
Power Avg 75.9W
Eff Max 66.1%
Eff Avg 44.5%

Why the CO27 numbers at 5.0V

How would I compare these 2 motors to determine which one will run best?

My apologies I know that this is not an easy question since dyno numbers dont really equate to track performance but in terms of theoretical performance which motor would be expected to run best for race?

CO27 may have been tuned for 12th scale.
