I got it running last night, albeit only for a couple minutes.

Here's the setup, then I have a question or two:

OFNA Hyper 7 TQ Sport kit
Feigao 8L motor (currently using a 15-tooth mod1 pinion and 47-tooth spur (I also have a 16-tooth pinion))
BK Warrior 9918 speed control (4mm gold connectors to the motor, Deans connector to the battery - soon to be replaced with PowerPoles)
Blue Bird 620MG steering servo (Torque: 126 oz.in, Speed: 0.15 sec./60° at 4.8V)
Hitec HFS-03MM 3-channel FM receiver
Airtronics M8 radio

I tested and ran it on one 6-cell unmatched GP3300 stick pack.

Lastly, my normal digital house scale (which measures only by half-pound increments) says the RTR setup with 6 cells weighs about 8 pounds. I'm pretty pleased with that, even though I know the scale may be off by a pound or so.

I didn't give it much more than 3/4 throttle because I didn't have everything secured yet. Even still, it was pretty quick and I'd say that even at 3/4 throttle it looks about as quick as my stock E-Maxx on 12 GP3300 cells in first gear. Unfortunately, I hit a little bump in my back yard and my servo wire got sucked through the pinion gear. It still works, but looks like an accordion now :) I'll probably end up splicing it if it shows any signs of trouble.

My question: I noticed a fair bit of cogging through the first 1/4 of the throttle, but it took off nice and smooth once I got through that "cogging range". Will the UBEC (Mike, do you have any yet?) help solve this, or is it something I should expect to live with? I did not try a receiver pack, but I'm pretty sure I do have the 4 dry cell box I got with a previous radio that I can try.

Second question: How many cells and/or how much voltage should I be able to safely put through this system? From the stats I've seen, I expect 14/15 cells or 18ish volts to be the top - correct me if I'm wrong. I'm just looking ahead for the inevitable urge to do speed runs :)

I expect to secure the components tonight and get a little movie recorded to demonstrate the "cogging range" I mentioned. I'll post a link tonight if I'm able to get it done.
