Thanks!
I haven't tried other brands on the A700, but maybe other readers can answer.

To respond to Howard on the A700 a lot of spur choice is available. Take note that I am only running 64P gears so your mileage may vary...For 17.5 and USGT I play with a spur size of 78T to 84T but generally run 82T.

It also depends if you are running a spur dampener and/or witch version you run.

With no spur dampener you have a lot of choice but ultra slim spur or offset spur may be a problem with the placement of the locating pins.

I prefer machined spur with a flat surface all around with about 3mm of thickness on the the SD1 (also need to drill two 5mm holes)...PRS is the way to go if you are able to grab some. The SD1 is a good compromise but you are very limited on spur choice...maybe somebody can chime in on that. The ARC spur is flat but too thin and you need to be creative to make it work.

On the SD2 you can run almost any brand of spur gears but overtime the SD2 create some loose/wobble so I prefer a spur gear that have some thickness on the gear area like Robinson or Xenon VSS to limit the chance of stripping the gear.

If you run a higher wind motor class like USGT no real need to add the mass of a dampener

Whatever you run if you are able to find PRS spur gears grab some on carpet I am able to run the same PRS gear for a season!

My small list by preference...

- PRS...no SD OK SD1 OK SD2 OK (durable and perfectly straight)
- Xenon VSS...no SD OK SD1 not OK SD2 OK (durable and straight white so you see when the gear have debris inside)
- Robinson...no SD OK SD1 not OK SD2 OK (medium durable but cheap easy to find and straight)
- Axon...no SD OK SD1 not OK SD2 OK (on hand but never tried it seems durable and straight but on the soft side like the Robinson)
- ARC...no SD OK SD1 maybe OK SD2 OK (medium durable and not straight)

Short awnser go grab a PRS if you can get them or buy a Robinson lol

For 21.5 racing I was using a Robinson 48P 50T pinion, had to add a 0.5mm shim under the ffg brace to clear the pinion as we were geared around FDR 2.7

Had a installation question about the Rear Floating Gear box. When I attached DT03 stepped bushing between AM81 and AM44-1, the gear box does not swivel left and right. Any ideas what I'm doing wrong?

Thanks

Hi jesses
You are not doing any things wrong...the RFG doesn't swivel left and right
it only allow the rear chassis of the car to flex more thus increasing overall rear end grip/traction.

Thanks for the confirmation Frankie!

Sorry another question... instructions shows the use of p11 sleeve between the spur gear holder At20 and bevel gear G03. In doing so, I have tons of slop. If I remove it, everything is nice and perfect with no play at all. So do I not use P11 with the rear floating gearbox?

Thanks for all the help Ova! One last question for now - I just purchased a new gear diff (GD2-S) and the normal din screw that goes in the output shaft were not included with the kit, but rather 2 small blue sponges in their place. Any idea where they are suppose to go?

Thanks in advance!



EDIT: figured it out - location was shown in the A800 manual.

Sorry if I am late for the diff question but for buyers of the latest revision A700 or parts you can follow the Max Mächler Awesomatix A800X Build's Tips & Tricks
Awesomatix A800X - Max Mächler - Build's Tips & Tricks

Yes some parts are different but for the diff just build it like Max said and you should not have any issues
