some notes using the Gear Drive...

I like that the gear drive gives me 40/17T or a 2.35 reduction that allows me to use bigger teeth pinions on my 90T spur. had by default the car setup with a 23T pinion (9.19 FDR) when i first tested it and it was slow... very slow. I changed to a 26T pinion, this gave me an 8.13 FDR and i loved how responsive the car felt immediately, swapped out to a 30T pinion which gave me a 7.05 FDR... gettimg too much wheel spin with 60 to 80% throttle settings on my controller. I need to get me a 25, 27 to 29T... for experimentation. hehehe

additional notes on the Usukani Gear Drive...

Locktite the moving parts... the spur gear holders grub screw unscrewed itself 2x, on the last it flew off. I have never had issues like this on belts or even my pro-d which had an 8.5T motor. The center gear and diff gear... those are locktite from the start, so hopefully i wont get into any issues running it for a while.

Some of the parts came in, the Sakura Ultimate FR+0 mounts and the 3racing pivot balls for it...

I ran into issues installing this piece, if you ran stock or alloy wiper steering then i dont think you would have the problems i experienced, but because I have the curve slide track steerng installed... it hits the front bearing mounts causing binds on the steering... defintitely unmountable. I had to shave off a few milimeters, actually I grineded until you dont see the silver part anymore (not sure how much because i kept test fitting and did not measure anymore).

Here is how it looks having shaved less than half of the way...

these pieces will be deanodized when the silver Usukani lower arms I ordered arrives.... in about a weeks time.

i've decided that I will just get the Yeah Racing adjustable rear lower arm come july and deanodize that too. Does anyone have any experience running that part?
