I have discovered a few issues when building in mid motor config.
Firstly, the turnbuckles need to be mounted to the rear most position on the bulkhead otherwise it fouls the spur gear cover when the suspension is compressed. Aside from giving an odd angle (as shown) it also means you need to extend the length of the turnbuckles to the point where there isn't a whole lot of thread left in the ball cups, which also makes them a bit flexy.



Secondly, & more worrying is the driveshaft fouls on the spur gear cover when the suspension is compressed thus limiting upward travel on that side, as shown below:



This shows the point of contact:



If you remove the spur cover the driveshaft then fouls the teeth of the spur itself
So far I can't think of a solution without changing some parts which would kind of defeat the object of buying a cheap kit !

I've fiddled with some of my Team C stock & it appears using either TM2 gullwing or tc02c straight rear wishbones & driveshafts with the BSR BZ 222 hubs would solve both issues though this mod will extend the wheelbase, & make it wider, though I won't know how much by until I build it up & fit the wheels (only relevant if you want it to be BRCA legal of course) This would be a shame as I feel the BSR wishbones aren't too bad otherwise.

This is a little disappointing regardless of the low cost of the kit, as running it it mid motor doesn't really work. I just wish they'd used a smaller 48dp spur gear, & therefore a smaller spur cover & motor plate which may have meant this issue wouldn't have occured at all.

I'll update when I have more info, hopefully tomorrow.
