What is everyone doing to the chassis to keep the lipo strapping tape from tearing? Round the edges?

Yes! ;-)

But another Question!!!

Iīve builded the car in a few hours, installed everything... No Problems so far... BUT! My pinions doesnīt fit, because they do not rotate in a straight line with the spur gear... About 2mm off... :-(

Has anybody the same problem? Or what pinions do you guys use?

Use two small pieces of double sided tape on the front and rear of the battery then use strapping tape. It will help keep everything in place. Otherwise yes round the edge and apply ca glue.

Did you flip the pinion? or is it just wobbly? Do you have a pic?

I'm sure this i a huge suprise....I run Trinity/Epic pinions.

When i flip the pinion (Xenon) then the screw havenīt enough to clamp...

Iīve tested a tamiya pinion... it works! I think the Xenon ones are to long!

So i have to find something like the tamiya pinions

Yeah with all the new touring cars you need the narrow pinions.

These are the spurs I have been looking at. My 72 tooth are one of these. You can only use two screws to tighten it down but I can get it in. If I run mod I will use 4 screws and the stock spur.

These are the Kyosho ones that look like they would work.

You won't be able to achieve a functional gear ratio with that 72. With a 93 the smallest pinion I could mesh, and even this was pushing it, was a 45 for a FDR of 4.13.

That would mean with a 72 you would need around a 66 tooth pinion to have any hope of achieving a mesh (quick from the hip calculations, feel free to double check). That would give a 2.18 FDR...

Buy some RWs in the 90-96 range (I carry 93 & 96s) and you will be covered.... Preferably V2s which let you use all 4 screws.

I saw that, hence the range suggestion. Out of stock gears must not show up, or it is discontinued. They did have them on 3/9/12!
