Very Nice Sikeston... I like, very much...

Sweet!

i look forward to a vid!

sikeston34m, keep it up!

You are doing exactly what I have wanted to do... looks great so far!

[suicideneil]

Ooh, now that is rather interesting, I like.

thats insane

[Mallanaga]

that's awesome! i love how low the engine is... makes me want to do something like it...

imitation is the best form of flattery, right? =P

Made some more progress tonight. I took it all back apart and used blue loctite on everything. Now all I have to do is figure out how I'm going to mount the receiver and the Quark Esc.

I have a Servo Tester. Little box with a dial on it that will control an ESC also. It duplicates the PWM that normally comes from the receiver.

Anyway, I couldn't resist hooking it up to 6S A123's and seeing the tires swell. They really do swell too. LOL These tires are REALLY out of balance.
I think this one is going to get the Phaltline tires with the Blast wheels that I've been saving. I originally bought these for my E maxx, got the aluminum wheel hub adapter kit along with them. Are the Revo and E maxx hubs the same? Will they work?

It's a good torque monster, I think the high gearing just might work without cogging issues.

Does anyone have suggestions on mounting the esc and the receiver? Perhaps some mounts that extent over the shock in the front and rear. I would like to keep these in the center of the truck. This will save battery compartment room for some high voltage setups.

Just make a little plate on to mount the ESC on top of the motor. Receiver can go on top of the ESC, or on top of the steerings servo (or opposite the steering servo).

Looks good - I look forward to seeing a vid.

Excellant Idea BP!!!!

I can use 4 PCB standoff's just tall enough to give me good clearance directly over the motor. Then I can mount an aluminum plate on that. The plate can be up to 2" wide and 6" long! I'll put them both there!

What would really be nice is to find a heat sink of the right size. Use it for a plate. Turn it upside down and let the motor fan blow on it. On the top side, attach the ESC to it with some thermal compound.

During my test run, I let it run at full throttle for about 5 minutes. The Motor was cool as a cucumber.

Hmmmm..........the possibilities.

PS..........let me get it perfected and I'll get some vids. This should be good.

Here's a few pics. The Motor only stick up about 1/2" out of the frame. I think there is enough head room there.

Dang man, that looks soo bad ass. That thing would be SO quiet... but then again, it's kinda nice to have gear noise as well! THere would still be diff noise, and tire noise as well...

[zeropointbug]

Oh, and what voltage, batts, esc are you using? Specs!

[sikeston34m]

At first I'm going to play around with 6S2P A123. Although I'll probably be doing some testing on different Lipo configurations too.

I'm thinking the 6S2P A123 will take me to about 40mph with some insane acceleration. Gonna start the play sessions with the Quark 80B ESC, but this baby needs some HV!!!!

I've been looking at the Kontronik Jazz 55-10-32. Then I could run 2 packs of 5 Series Lipo's. Maybe the 5000mah versions for a 10 Series setup.

On HV, maybe the best thing to do would be to get the RCM buggy diffs. Get both the 4:1 AND the 4.3:1 ratio's. The motor would be spinning so much faster on 10 Series, I could trade some top end for more acceleration.

I'm gonna test it first on the lower voltage. All that HV stuff means shelling out some bucks. I wanna do a little more research on the HV ESC's first. I would love a Car ESC with reverse that will do 10 Series and get along with outrunners.

I think I have alot of power here. Some testing is in order to find the perfect balance of acceleration and top end.

It just about got away from me when I was running it. Now I look like I have a serious rug burn on my arm! LOL

Looks awesome DUDE!!... More voltage.. more more more... :) J/K

Go for the 10S.. it would kick butt..
