Tamiya TB-Evolution IV
#3122
wanna ask a question about the battery holder on evo ms, if using isolated battery rather than stick pack, besides glass tape, what else can be use to hold the battery? cos if i am using the plastic holder come with the car, the battery might be able to move and hit the shaft in the middle or might be able to drop out of the car. thx

A friend of mine recently had this problem, grab 3 ball cups snip off the ball section, and use them as plastic posts screwed to the chassis, 2 on the outside of the battery, and one on the inside rear to keep the last cell away from the shaft drive cup.

When I had my Evo4 ages ago, I used a Yokomo MR4-TC Graphite Battery bar as this uses the same dimensions as the Tamiya one but is extremely rigid and not flexible like the Tamiya one. You could tie a knot with the Tamiya one it was so flexible.
The Yoke bar fits on the existing Battery posts fine and works great. Never had a battery come out EVER.

I sanded and smoothed my chassis and top deck and sealed it, remember if your using tape to really round off the slots where the tape passes through the chassis otherwise it can cut through the tape.

As to sealing the chassis, again I think it's important. You are running a electric car and the carbon fiber chassis conducts electricity. It's just a good idea to seal it. Plus I think a sealed chassis prevents a lot of glitching problems and protect the chassis from splintering during crashes.

Very good points...So do I do all of this filing and then just run CA glue along the chassis and barrery slots? How do I seal is and what should I use...This is not my TB02...I really don't want to mess this car up

Just file the edges of the chassis & top plate to get the sharp edges off. On the battery slots you will want to take your time and test fit a pack quite often to make sure you get the batteries to sit flush with the bottom of the chassis, but not sticking through. Once you get all that done, then use a Q-tip and apply thin CA to all of the areas you just filed. Take you time and it will come out good. I think Calandra has a how to article on their site about chassis prep, but I can't get their site to load right now. Good luck and remember to TAKE YOUR TIME.
