setup
2250kv 80 esc
2 7.4v 5000 mah pack
25 pinon 49t spur

looks good..a couple of suggestions

1. some kind of padding around your li-pos to cushion impacts
2. velcro instead of zip-ties to secure batts
3. what steering servo are you running? w/tires that big you will NEED a huge tourque servo....something over 300 oz.
4. the motor wires in the pic look close to the spur...secure them and braid twist them to reduce interference

+1 on the motor wires, plus rotate the motor so they aren't stressed so tight.

Otherwise nicely done.

thanks for the input ...the motor will be rotated and those batteries have changed to hard case pack those were just to see how i would do things.

Looks good, although I'm not a fan of the MGT's transmission (heavy, complicated, lots of rotating mass), I doubt you'll have any problems with it.

A few suggestions for you though.....

- Have you gotten a FOC and locked the transmission in 2nd yet?
According to a post I read over on URC, you can use the AE Forward Only Conversion kit for the transmission to lighten it up and make the internals a bit less complicated, as well as lock it into 2nd gear for a more usable ratio, and with the FOC locked into 2nd gear, you can still have reverse via the motor turning the opposite direction, and it is a win-win situation, the FOC gives you less rotating mass, it eliminates the need for a reverse shifting servo so it lightens up the truck overall, locks it into 2nd gear for a more usable ratio, and makes the internals of the transmission less complicated. Here is a link to page that the post is on, it's post #15, so scroll down a bit - http://www.ultimaterc.com/forums/sho...t=65876&page=2


- Try to remove any excess components from the truck, the lighter you can make it, the better, especially since you are only running 4S and have those massive wheels/tires on it. Trim the radio box up as much as possible, for instance, cut off the battery box part of it, anything else on it that isn't needed really. I don't run a receiver box on my MGT because the back of my motor is just a few inches behind the front shock tower, and not having the receiver box there lets air flow over the motor. In you case it probably wouldn't make much difference, but if you don't mind having your receiver out in the open, I'd suggest cut the receiver box off that whole tray assembly as well.

- I think you made a smart choice with using a separate brake servo instead of motor brakes (will motor brakes even work with the stock transmission since it's got various one way bearings in it? It's been so long since my MGT had a transmission that I don't remember, lol), the mechanical brakes will keep the temps quite a bit lower vs. motor brakes, but if you go with another setup later down the road with more power (like a lower Kv/higher voltage system), I'd suggest getting rid of the mechanical brake setup if you can because it's just extra weight.


Keep us updated!

i done that already so it forward only and lite i will be testing it soon have replace the spur gear

Resize your pictures- 800x600 pixels is plenty; not all of use 32" monitors....

This is what I can see of the second pic on my 15" monitor:




Is it attached to a truck?
