wide hex. never seen them before so I bidded from crusaderlf in ebay, they are good if u wanna use modern flat dish wheel on optimas.

Apart from the shortcomings Coelacanth mentioned, the optima series suffer from understeer if you're using fast brushless system due to their rear heavy design. the optima pro was suppose to address this issue by placing the battery a little further to the front. The belt system can also slip a litt...

Optima went thru hell and back today, the LMT 4200 motor proved to be too fast for the track, the damage: -bent shock tower -bent motor guard -shock rod end broken -counter gear chip off -broken shell got even more broken The ultima final pinion was worn due to dirt got into the gearbox, but seems s...

Thanks Marc anyway I'll be hitting the track tmr with my optima with the belt chassis and report on the durability of the ultima final pinion, I just hope the weather is good.

wow that is rare stuff, I've never heard of it too,looks like can adjust the shock mounting hole, nice score!

if the roll cage is molded in black, I wonder if they are going to do the same for wild one next time

nice work, keep it up! how's the finishing of the white repro tub? btw I think the CRP wing does look a little oversize for the TS though.

ok decided to give it a quick sand down to give it a little shine, then took this belt optima out for a test run to check for fault,using lehner 4200 motor on 15t pinion, it still wheelie under hard acceleration. it's now ready for the track :) will report back on gear durability in another week or ...

great stuff, seems you've bought a lot from gasanddesigns? Is your turbo Rocky by William?Think I saw it at TC, when I wanted to message him, it's no longer there, you got it first

I'll update on the durability of this mod after some track time, I hope to finish it soon and hit the track. The belt does need some silicon oil to soften it a little.

in the process of doing up my belt optima for bashing at the track, I decided to try ultima's plastic final pinion. here's some pics of it, it works and will need an E clip to secure the shaft. the metal plates are very used n somewhat rusty, but I think I'll just leave it as it is since it's gonna ...

wow this is gonna be a nice build! I'm a sucker for scorpion series myself.Can't wait to see your finished product :D I'm still missing a Turbo Scorpion in my collection :oops: The gearbox is very loud, for some unknown reason my tomahawk's differential gear is a little bend making it even louder :(

nice score! your shadow looks mint!
