I think for phatladz it’s 50 but I could be wrong. I have megastars on right now just cause I didn’t have the right type of bolt for phatladz

Gotcha, I have to rockstars so I am now assuming they are different sizes depending on what wheel.

I appreciate it Paul.
I spent some time with the Dremel and now I have 55mm ish bolts.
so all good.
got the motor shafts cut down as well.
the 50 mm bolts did not stick out much past the nylok nuts.
this is the 55ish
I think I will have to add speed rings to the spacer behind the wheel.
it is a pretty snug fit with the adapter.
so I am moving along.
trying to decide if I get lazy now or keep going tonight…

My adapters for Apex airs were too tight so I’m having to get them machined out wider.

Really? Maybe I got lucky but mine were perfect fit. Must be some variance on one side

my top speed with my previous setup is 4.6 and i only got 55 kph and the calculator give me 61kph loaded
that why i don’t trust this tool
You may need to adjust your efficiency. 90% can be optimistic depending on a lot of factors

did you double check your wheel size with calipers? was your battery not full? were you going up hill? did you set the efficiency depending on what wheels you’re using?

l was so happy to receive my AT drive system but now i am a little mad and i will have to wait fews day or week again, : l tough kevin , forget to send me flat concave screws but is answer was: use the the flat M4 x 10mm Flat head , wtf dude , l will never ever use a flat screw on a concave surface , just to give you a idea , .15 year ago by mistake l lost one of my rear car wheel because i was using flat bolt on a concave mags wheel , l mean this kit is well build but it make no sense use it for now , because without theses concave screws this rotaring parts will definitely become loose soon and the flat screw can’t sit correctly ! , you can ask a mecanic or a electromecanic, or a machinist and the answer will be the same as me ,
