the incubus , I have been watching.

All I see is my buddies at the track constantly trying to tune, dial , reset, replace broken parts, replace cooked electronics and so on. None of that seems very interesting to me.

Then the D413 shows up.....

Still watching....

From my statement I'm saying YES you can gear down enough with the stock spur. 11.91-to-1. I'm looking for proof that other cars run gearing lower than that.

I started the whole debate! My car is still on Back Order! I was trying to help other guys that seem to be having problems. I NEVER had heating problems in my previous wheelers
I stated to look at timing, boost and turbo and current limit which all help in motor temps
I have had same system in my cars RS Pro and 6.5 This time I have an RSX esc
I'll post my findings when I get it built

T.Deguzman, do you use X Rings from AE on shocks?

There is plenty of room on the D413. Why NOT put a 550 size motor on it ? I would think a 550 would run cooler.
Then do it...
I know this guy personally and he really doesn't care what ppl think.
He's also the biggest NERD I know!
So to you Matt, get off your arse and buy one already! Can't wait to drag you around the track with my old out dated XB4! Lol
Oh yea, it only has a 540 motor.

Everyone drives different! When I drive my buddies b44 it thermals in less then 5min cause I drive a lot harder then him. But when he drives it it comes off at 140. The way you drive adds a lot of heat. If you use a lot of breaks that adds heat. You don't need add to go into the body. You mostly need air to escape out the back.

I am not sure what the issue is with asking if there is going to be larger spur gears available. Every company, including hot bodies, has different sized spur gears. Every 1/10 and 1/8 cars I have seen have an option to change the spur gear size.
Granted the kit is very new and at this point in time a different size spur gear is not available.
If a spur gear will not be available, then its a matter of going down in motor size to help with heat issues.
So it's either an option later to buy a $10 spur gear or to buy a $150 motor now.

FWIW I run a Tekin Pro 4 in my wheeler. It's not in a D413, but it is a fantastic motor for a 4wd buggy IMO. Temps ~130F after a 7min main driving pretty hard, and only weighs a little more than a 2-pole 540. And in this case, you wouldn't have to worry about gearing down due to the lower kv.

Whats the difference between running the 3dot with 3dot front kick up and 2dot with the 2 dot ? Chart shows both equal 10 degrees

How do you gear for it; do you treat it like a 6.5T for example?

i'd be more apt to try a 5100kv pro-2. i think some of the issue may be the center diff. having another diff to drive probably makes more heat than a conventional 2 diff wheeler.

Roll center, less dots high roll center, more dots low roll center

Mine is geared to an 8.14 final drive (I'm using the equivalent of a 4200kv). I think that's more like 10.5 gearing? Not totally sure though. I gear using the kv, nominal voltage, and 84mm tire dia to achieve ~37-39mph. That puts me in the general area to start. In this case I'd probably start with a 31t pinion using a 4000kv Pro 4.

The local AE Team Organizer runs 16/81 on a 6.5 in a B44.2 on the indoor astro track. I don't know if there are any other tracks like ours in the US, so it is probably a non-issue for everyone.

This is how I mounted my MuchMore fan. I cut down an old Ackermann rack bushing so that I could still tighten the screw down without deforming the fan's plastic. With the way I mounted my ESC, I didn't really have any room to mount it on the chassis like Ty.

If you would've mounted your motor with the wires up top you could place the fan on the outside of the motor using a Spec-R fan mount, though you'd have to drill a small countersunk hole most likely. Or, you could move the Rx up front and place the fan in the rear of the motor which is easier and more ideal. This car has PLENTY of real estate.
