Hey Guys, here are some pictures of what I did to my TT-01. It's a simple mod that can definitely be improved, since I merely used a sheet of plastic and xacto-knifed the screw holes. It gets the job done though.
What I did was take a sheet of plastic, and cut it to around 3/4 of an inch in height, and 3.5 inches in length. After that, I Xacto knifed holes by sight of where the shocks mount on the supports. Putting another two holes a centimeter down from that one will provide a place for the shocks to mount, and overall your height will be raised. For me, This came to about 7/8 of an inch clearance in the middle of the chassis.
You are going to need to trim certain places though. The skid plate has two sections that keep the lower arm from fully extending
Also, the upper arms will rub with the shaft connecting to the differential, so you need to shave a bit off.
^^ Rubs there
This eliminates all binding that happens in the drivetrain. If it is still clicking when you pull the throttle, hold the chassis, pull the throttle and compress the suspension. If the clicking continues, it is in the gearboxes or spur gear. If it stops, you can shave off more from the arms where I circled. You're going to need to shave some from the front arms too. If you look at the front arms you'll see which arm it rubs with.
In the end, I can almost drive in grass. If I get some larger block tires I think I'll fare rather well anywhere
