It must be a camera angle, because the motor mount is very strong and large

Yeah, just looks like a bit of 'fish-eye' type distortion from the camera lens.

Awesome build Gone, should be a serious bit of truck when its completed.

Yeah, I thought that too.. Gone have you calculated the speeds on that setup http://scriptasylum.com/rc_speed/?

The top Speed will be about 50 mph (80 km/h) on 1st gear and about on 2nd gear 62 mph (99 km/h)

Wow! I'd expect about 55 max because of the massive amount of drag that truck will have.

I'm sure that thing will go faster than 60MPH... 3330 watts is a lot of power...

Yeah, my XTM is longer and maybe a little heavier and it has no problems breaking 70mph, except for keeping it on the ground.

This is such an awesome project. Great job on the truck gone!! Looking forward to the video(s) and the finished product. :yes:

thanks you :oops:. Now, I need to a new charger, I would like charge my both lipo 6S 4900mah 25c at the same time, I think to a Hyperion EOS0610i DUO or a power peak infinity 3, but what is the best ?

I would get the hyperion, only $60 more, built in balancer, and 360 Watts.. double the charge output..... I love mine... all of them.. :)

I would say the Hyperion too, though both look rather awesome.

One guy gave me a little secrete that is working great. What I did is the following: I disassembled my front shocks and added a piece of silicone tube to the shaft and put it back in and that actually stopped my truck from lifting the front end. I also added silicone tubing to the rear shocks (Doesn't need to be disassembled) shaft to stop it from squatting. Now you will have to decide how much up travel you want in the front and make sure all the tubing is the same length. I chose silicone tubing, because it offers some damping, but you can use any other kind of tube you want. I tought it would work, but it does. My truck doesn't lift it's front anymore.

I have silicone tubing on all 4 shocks already and also a custom wheelie bar. The wind is what is taking the truck....its all of a sudden to. Also its not consistent. Usually around 65-70mph range the truck begins to sway the rear end side to side as lift is created on the rear of the body, then past that it will sometimes just take off....like an airplane with wings. I'm working on reducing frontal area as much as possible and lift. Also I am working on making some bolt on difusers for the rear of the chassis. The MMT is the perfect chassis for high speed runs since its a flat panel. All the other big trucks have an open chassis underneath which creates alot of lift. Also the longer the wheelbase the better I have been with holding the truck down.

Do you have tubing inside the front shocks under the piston? I will start doing speed runs again soon and I have my truck sitting a bit lower on the front and I know it will create much more down force, but I know it will stay on the ground. I also have a wheelie bar, but I think it won't be needed. I sure hope Mike can do my chassis soon. With the design I have done, I can use 44.4v and 74v with those long packs from Kong Power, Flight Power and Thunder Power.

Yes I have the tubing on all of the pistons. Works good. I have also found the other trick is to strap the front suspension with zip ties to not allow the front suspension to unload, essentially making the front end dead weight.
