It's possible to make it work with the battery strap. Someone I race with did it, but it was a lot of work with a dremel.

I got rid of all 3 "inside" and the center "outside" battery holder parts. Just left the 2 "outside" corners. Used the "foot" of the original motor mount on the "inside" center hole. Put the flat side of the "foot" towards the battery, concave side towards the belt, screw up through the hole in the bottom. The belt touches the "foot" but it doesn't bind or cause much friction and I haven't noticed any wear on the side of the belt that touches in in the 3 months or so that I've run it that way. Tape does the rest. I double up 2 pieces of battery tape about 14-16" long.

I only take the battery out for a couple of things. To balance charge -- on my battery, the tape covers the balance hole. I've punched a hole in the tape before, but I've always been worried that would weaken the tape too much. Other than that about the only other reason I take the battery out is to change the pinion or mess with the gear mesh. The tape lasts about 6-8 race days for me -- I race about 2x a week, so about a month or so. I do "normal" battery charges with the battery in the car.

The center battery mount is where I replaced mine with a nyloc nut just to keep the battery from shifting. it works great and the belt clears without any issues. You can still use the battery strap.

You can still use it. You just have to Dremel the inside barriers. I took the inside center out, Dremeled the front and back ones. The put the center one on the upperdeck. Sideways, with one screw and a zip tie. Its kinda Old Testament but it works.

You can still use the battery strap with the vertical motor mount. Just upgrade your battery holder.

That looks interesting. What battery holder are you using? Please post what you're using.

I went at the stock battery holders with the Dremel last night and have something that might work. The battery can still move inward a bit too much and I still need to resolve that. If your battery holder is better I may just switch.

Found the battery mount by accident and didn't pay attention to the brand at the time. Too bad I didn't save the packaging. Got it at a local shop but the shop has recently closed down. I'll try to look it up online and let you guys know.

Your setup looks like the cat's meow and I'd be interested in knowing what battery strap/tray you are using for sure.

It looks like a TC6 battery holder to me (strap not included).

While we wait on that battery retainer that ariemus is using, I made some mods to the stock parts and I can now use the battery strap. The lipo can move slightly left to right in the tray and I'll see how I can fix that next. Here are a few pics.

SteveM Your DIY looks good, don't need to upgrade the battery strap at all. To prevent the the battery from sliding, just add the battery stay. See my photo, its the round pink piece thats just under the top deck. Add 2 of these. See the Sakura XI for info how to do it. Although the XI has a battery stay on the motor mount and steering. You can DIY like mine. This piece will make the battery snug against the outer battery retainer and prevent battery from hitting the belt.

Looks like your stay is attached to the upper deck. I'll look into something like that too.

The TC6 parts I need (ASC31318 & ASC31304) aren't expensive so I'll order those anyway as they make for a cleaner install.

ok Sakura Masters,

I got a weird one.

Using this car for VTA Racing with 2S and 25.5 Novak Ballistic Motor.

Geared 4.84 with a 92Spur and a 38 Pinion

19T Center Pulleys

Front Diff 30,000wt
Rear Diff 500

Other than that stock everything else

But on our track I'm getting the motor up to it's Temperature limit.

Now my Other VTA car a Associated TC4 FT (shaft drive) Geared taller at 4.6 comes in no problems after 10 min at 130F


No Timing advance on either car and the same track with the same traction.

Anyone got any Idea's?

Also the Track is very Very tight lots of 180 degree corners and about 40x60'



The current gearing is the smallest I can go in pinion as the motor is tight against the motor mount



With the Pinion off the car rolls free
