For me yes, its the best out of the box, poised,light,balanced .quick , reliable and reasonably strong for the time , a spare rear gearbox housing needed but they are cheap.

OK, yes stock ball diffs, gearing for the 6.5 T was 18 T pinion, stock spur It now runs a 8.5 T , 21 T pinion stock spur, iirc I have regreased the ball diffs but other than a front shock tower and a couple of sets of tyres no dramas with years of running

Egress's are capable of taking huge amounts of power.... My re re started off with a 6.5 T brushless system, it's no slug. I also fitted the 3rd ball diff out of my Avante 2001, it grips, it handles and it's smooth, it's heavy but it's also light years ago of a Super Shot. When i first built my Egress it made about 5 of my runners redundant

Cutting it fine , but the Astute was released in Sept 1989 and would run rings around a Fox, with the Super Astute being re re'd parts are available, but a good Astute is very hard to find......... I have many Super Astutes but only one Astute, it was a real mess when I got it, literally half a car, but with help from people here it lives again

No plans here, I bought the pargue one for mine before the world got weird and postage was reasonable, If you are in Australia I can post you my old broken one, would be perfect to copy

Is the pinion loose? is the motor mount fitted correctly?

It could also be the ESC brakes

Anyone ?

I have converted a Losi JRX2 to mid motor in a similar way, I was able to drill the gearbox housing and flip the spur shaft so the motor wasn't reversing all the time, you could just run brushless with zero timing....

I just measured my vintage and re re Supershots, they are both 100mm

I would drill a second slightly more inward shock mount hole in the rear tower, a bit lower, it should help. Or you could get a RC Channel rear tower too

I think they used a RC Channel rear shock tower , that would be the variance in length

The ESC may be in brushed mode?

Yes the original Evolution parts are frp, no Tamiya didn't make any carbon hop ups, but you can buy carbon replicas from Fibrelyte, I have 3 sets , they are awesome

Thanks much appreciated, I"ll give it a few days and if still no luck I'll be in touch
