Ok guys, I have a feeling you're going to like this one. I've got a MGT on it's way (parcel post... UGH!) So it should be here late next week, probably thursday or friday. It's already been converted to brushless using a KB45 motor. Although, I'll completely be stripping down this MGT and using it for parts. I'm also working out a deal for a complete MGT 4.6 roller. RTR without engine. Here's the plan: I'm going to remove the diffs and put 4 outrunners in their places, all rewound to ~180kv for operation on 3s each. Yeah, that's right... 4 motors, 4 esc's, 4 batts. Here's what i plan on running on each axle:

Here's what I got for the operation:


Differential Ratio: 1
Transmission Ratio: 1
Other Ratio: 1
Spur Tooth Count: 1
Pinion Tooth Count: 1
Total Voltage: 11.1
Motor KV: 180
Tire Diameter (inches): 7
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1 : 1
Total Ratio: 1 : 1
Tire Circumference (inches): 21.99 inches (558.58 mm)
Total Motor Speed: 1998 RPM
Vehicle Speed: 41.61 mph (66.84 km/h)
Estimated Adjusted Speed: 39 mph (63 km/h) - 5% loss
Effective KV Value: 180
KT constant: 7.51 oz-in/A
Motor Torque: Amperage not specified...
Final Torque: Amperage not specified...
Final Power: Amperage not specified...

I think this will be a fun setup, to say the least. Input? Oh let me get to the firepower.
I was thinking one of these because it fires at a decent FPS, and holds a lot of ammo, as well as it looks like there is alot of plastic that can be removed.

Also, going to do a rotating rocket mechanism, mounted to the top of the cab. I'll get some pics when the first MGT gets here. If you have a complete rolling chassis MGT for trade for BL stuff shoot me a PM!!


Get me back into RC!
