Maybe you can convince him to swap batteries with you, hee hee....

Sounds to me like you should be good.... except for the pinion issue.

You could try red loctite, if you have been using blue...
Or maybe use some JB weld around the grub screw, as if you were making the pinion thicker. This will give the screw a little extra something to bite, and act kinda like a locknut. Just a little mound of it surrounding the screw...

Maybe this is too obvious, but can you get the screw any tighter without stripping it out?

No all i could do is two turns for tightening the grub screw. anyway wat i was using was blue locktite. What i did last night was put some superglue. will be trying today if it will work.

If you are brave and have some sort of puller. You can put the loctite on the
shaft and slide pinion on to let dry. No grub screw required. Just hard to get off.

crazyjr: so u mean for my MOD1 11T&13T i need a 49-51 spur gear and a strobe slipper? who makes this kinds of spur gears and stobe slippers? m in manila so it will be hard looking for this things. or ill have to wait super long to get them from the states

ill ofna spurs work or kyosho with mod1 pinion? lets say 50tspur/13T pinion will this work for a small track with lots of turns and one straith away?
