Further, the SC700BL speedo that comes with the RTR RS claims a motor limit of 5500kV. How does this translate to numerical brushless motor specs?

I'm considering this ESC for my XX-4 project, but I surely don't want a melt-down...

That sounds more like an 8.5T

When putting the 3oz of weight in the back do you stack them or lay them flat like 3 in a row?

I cut my battery pad in half, run the battery centered, then cut the rear half in half again. Stack the weight immediately in front of the rear bulkhead. The weight should be in 1/4 oz pieces- you can stack three rows, width wise.

I double stick them to the bottom of my battery foam spacer. Three rows flat. I actually have three foam spacers with one, two and three rows; add more weight as the track dries out. Much easier than peeling them off and on.

Raven, RPM has some pretty durable stuff for bashing.

yeah, I've got their arms on it.

I am going to be racing it but have heard you need to do a lot of little tweaks to get it to run properly. The reason for not going Lipo off the hop is the price and the fact that I want to learn to drive it before making it go faster as that to me is a quick way to break it. From what I have been reading some vents in the rtr body is a must to keep it mostly level in the air. Also the indoor track we have is carpeted so apparently need to look into some heavier oil for the shocks. I want to keep the vehicle as close to stock as possible as it keeps you from getting grief from the local rule jockeys.

Speaking of cutting vents in the hood, does anyone have any pics of this? Like how many, how big, and where has proven to be most effective?

I bought a new-to-me SC10. Great condition. I mostly on-road race at www.RCARIndy.com. But, my son and I also off-road race from time to time.

The truck didn't come with a ESC or motor. If I just put the RTR Reedy Radon 17 turn in it will performance be decent or is it really slow with that?

For as often as we run off-road, I didn't want to invest in a brushless system for it. I've got a NIB speed control, but it will only work with brushed motors, so that was my plan. I just need to by something inexpensive and brushed.

I would suggest a quality 19t motor. The stock 17 turn motor is ok power wise, but will not last very long at all. I'm sure some old checkpoint or orion V2 19t brushed motors are still out there on ebay or something for $20 or less.

Good advice. Thanks. I'll check. I use ebay a lot.

with the cost of some of the speedo's out there nowadays, you probably can pickup a brushless unit really cheap.

That said, you could try tuning the motor like the old school days of brushed. If you really want to run with it, maybe someone local to you has an old comm lathe that will work with the can in there garage.

just check the F/S threads on this site, i bet you can pick up a BL combo real cheap.
