Sorted the spur clearance with some judicious shimming, there are now 5 0.2 shims on the layshaft in total and it now clears the obstruction, I'm just worried what thermal expansion will do to it, guess I'll have to suck it and see.
The TA05 battery strap DOESN'T work with a Trakpower cell as regardless of which way round it goes, the strap half covers one of the terminals, so I may have to Dremel it or stick to my Core 3250 lipo
