I agree but when I try my older losi wheels even with the smaller serrated locks it wont work. Had to get the Avid axles. I also have a zx5 and the losi wheels wont fit. all the others do though with those nuts.

I had to make a battery strap, b44.2 ones werent long enough, maybe a shorty strap would work. I am going to send mine over to a friend to have it cut out of carbon fiber. Also need to get another back battery brace because previous owner hacked it up with a Dremel pretty good. I'll post pictures later on.

Are you guys running longer axles, serrated nuts and aka/other rims, simply because you can't buy Kyosho's at your lhs? Or performance related? Thanks,

the avids are longer which are better for some rims..they are much stronger too,and guaranteed not to break..you wont break the kyoshos often but they may break

Picture of the battery strap wiring and pt in there. It really does have a ton of rear bite. I will have to check it at the track to know exactly how it feels.

If the aluminum bones are anything like the pucks setup on the cup side that attaches to axle, then prolly not cuz mip uses US fractional size setscrews and such. Prolly need the whole alloy driveshaft kit if my assumptions are correct and use the mip axles. If they are
Like the puck axles, then they are good bc mip added a few extra threads on the axle. Just look up the exploded view and parts list of the alloy driveset in mip's online site to see what misc hardware they are
Using.

That looks sweet. B5m Finnisher? It looks like it fits perfect? Did you have to "make it" fit any where or is it pretty close to right on? I love how it covers all the way to the shock tower

Its not perfect but close to work. Just be careful to trim around spur snd front.

yeah, idk why none the rb6 bodys go to back but i like thid one, still holds with velco on front and back sides. Mid body is too wide for velcro. I used a spot of velcro on top tranny too.

It looks like a small enough gap to deal with but I wonder if it will effect the flight while jumping?
