Much better performance than the old motor. The stator is longer, but the shaft is the same overall length as the old motor's shaft. I like the fan idea, am I correct in thinking it bolts to the can with the fins pointing away from the motor?

I do need to wire up a ubec and make a battery tray, did not have any deans micro connectors for the ubec so I used the rec pack instead. The quark and the lipo barely got warm. The lipo did not have any issues, and I got about 20mins out of it with some left in the pack.

I had the settings as you describe, save for having the cutoff set at Lipoly High. I need to change that as I like a 3.2v cutoff.

I need to experiment more with this setup, I would like to go with larger tires and maybe drop down to 4s as the truck is plenty fast with the current setup and taller tires will just make it faster. The redcat seems to be holding together ok, only the servo saver spring is too weak and causes alot of slop. I may just make it solid at the the bell crank and use a heavy duty servo mounted saver.

Scratch that, I see that the fan blades point inward toward the motor. Does it draw air through the motor like a squirrel cauge (a/c) fan or does it blow air through?

It draws air through the motor, and blows out at the fan. The mounting end is where cool air enters, the fan end is where warm air exits.

The 41xx version moves a good amount of air. I'm sure this one will too.

Woo Hoo! The Mail Lady came today bearing gifts!

Hey! There's something there on the left that you could use Linc.

(Notice: The little smiley is looking right at it! LOL)

Yeah, I have 2 of the ccbec brand new in the packs. I like to attach them to the esc wires by means of a short length of small gauge wire with a micro deans on it. That way I can remove the esc without having to remove the bec. For 20 bucks or so the ccbec is cheap enought to have one on each vehicle. I need some micro connectors so I just used the rec pack.

Metalman: so far the red cat seems to be well made in the diff and suspension department. I am having issues with the steering servo saver that is built into the bellcrank. I will try to find a stronger spring to tighten it up, it is a little sloppy at the moment. I am actually thinking of moving the steering servo and the motor mount so that I can fit an emaxx tray on the battery side of the chassis. Would lower my cg and look neater. I am sure that the off set motor would be ok, as the torque effect would be less pronounced. Moving the motor over would give the chassis more leverage in counteracting the torquing of the motor. I wil lift the steering side tires almost off the ground under hard acceration now!

How hard does it accelerate?

BL_RV0 · 12.07.2007, 08:28 PM

let us know how that fan works.

Very Hard!!!!

If you punch it from a standstill it takes off spinning the tires violently, and then usually torques the chassis and unloads both tires on one side and then spins out, sometimes flipping over. Once the tires warm up the grip much better and that helps. It is not slow at all, must be near 40mph, need to radar it when I charge the battery again.
