You won't fit smaller then a 34 cause you can't move motor over far enough.

You could use a 72 tooth though
Thanks DBL15, I'll play with your gearing combo.

Out of frustrtion I did a bit of googleing and found this website: http://scriptasylum.com/rc_speed/gear_calc.html
It helped me calculating the distance between the motor and the spur gear shafts and then determine what spur/pinion one could use. I'm just sharing it as it seems very useful.

Same thing happened to me and nearly destroyed the whole car, battery came out off the holder moved forward causing the wires to wrap around the spur, lucky it didnt short circuit it would have fried everything. I also run my battery across the far back, definitely investing in the ones Bezerk make pauls work is awesome.

What's the running weight for this car? I know tires/foams will be a variable factor but just looking to see how it compares to a d413 & 44.3 I have a yz-2 and love how light it is and wanna sell my d413 & 44.3 for this car

Default BATTERY ISSUE

what shorty or saddle packs are you guys using?

Whilst some people are having issues with batteries moving all over the place, I cannot fit my turnigy saddles. The clearance between the chassis plate and the top battery plate is 24mm approx. but my saddles are about 25.3 mm thick (I thought 25mm was kind of standard). Can one only use low profile batteries with this buggy? has anybody experienced something similar?

I removed the top battery plate and the saddles fit in well but there is nothing hodling them in place... so this is not an option.

Cheers

No issues fitting Vant Saddles.

I had space between my motor and chassis. There does seem to be a little play side to side in the lay shaft, thus mine has a 1mm to 2mm gap.

Maybe you can shim the topdeck up a few mm.

I use Vampire Racing shorties in mine, but have had the Vampire saddles in as well, just to make sure my wires would let me use them if I wanted to try them.

Both types fit ok with the top plate.

What is it that's stopping you from fitting the top plate with your saddles?

Sorry I only just noticed this post. I run turnigys also, and have had to space the rear posts that hold the carbon battery retainer up by 1.5mm.
All fits in nicely now - Didnt have to do anything with the forward post.
Its just a case of putting a shim between the chassis and the battery posts on both sides.
I run shortys but Id guess saddles will be the same.

Hi John Myall and Glarke,

So I worked out that the space between the chassis plate and the carbon battery retainer is 25.5mm approximately . My saddles go from 25 to 28mm (they are a bit puffed up), so fitting them in the car is very difficult. it is so tight that the battery retainer rips off the battery brand/model sticker every time I try fitting them in.

I tried adding a 1mm shim to the battery posts but then the left arm of the battery retainer plate is in direct contact with one of the bearings from the rear belt tensioner, jamming it. Glarke, does this happen to you after shimming the posts? It really doesn't stop the belt from moving but I don't like the idea of having that bearing static, they were put there to rotate as the belt runs.

I don't have shorties but a friend measured his turnigy ones and they are 27.1mm thick. I didn't really want to buy big brand batteries, I can buy 3 or 2hobbyking packs almost for the price of 1 from a bigger brand...

I'm discussing with Bezerk Rc about making a custom battery plate 2mm or even 1.6 mm thick.

Any thoughts guys? I'll post some pics tomorrow.

Thanks gents

I have the rear battery mount posts shimmed up 2mm, as there was just too much flex in the hold-down with foam under it for my liking (over a 25mm+ shorty pack running off-set and parallel to the chassis). I still have a good 3-4mm between the hold-down and the rear tensioner bearings.

It's sounds like maybe the front post retainer screw is set too low, causing an uneven angle for you. iirc, it has a washer/shim between the screw and the post. Maybe try and increase that height and it should level the hold-down out a bit, allowing for the shimmed rear posts not to cause your current issue. Even just shimming the base of the front post up instead of the rear should solve the tensioner bearing problem.

As mine is now, I'm pretty sure I could shim all the posts up a lot more if I had to, and hold a 27-28+mm thick battery without any issues.

SMC? I just measured my shorties (100C) and one edge (opposite the terminals) came out 25.08mm, anywhere else was 24.8x mm. Not suggesting you should have to go out and buy new packs, but other options exist with a good price-point. Specs say 25mm on the Turnigy packs too, but if they're consistently a couple mm off... On the other hand, puffed packs are a different problem.

As to a thinner hold-down - if you need a little more stiffness but more clearance, you might be able to make it narrower only at the ends (or double up on 1.6mm on top through the middle of the hold-down) if there's clearance. I don't have the car so can only look at the manual, but it seems unlikely it contributes to chassis stiffness significantly.
