the right spur gear for mod 1 11t & 13t ?

Hey guys the natinals is over and i did 2nd in qualifying and 2nd running during the 1st heat and didnt get to finish because my pinion"s grub screw was gone again with super glue holding it already. tried to solder it but last only for 3 min. so ended up not even getting points. anyway getting back to my question right nw m geared with 66/18 and m wanting to change my pinion to mod1 cause it could fit the 5mm shaft of my 9XL. So i need SOME HELP here cause m so frustrated today. would appreciate some suggetions on whats the perfect gearing. i already have the MOD 1 11&13T pinion. also what spur will match with my existing pinion and what brands couls i get.

you can get the 32 pitch gears from Mike as well, look in the transmission and gears section. As for mod 1 you would need a 49 to 51 and a strobe slipper

There is also another source for 5mm 32P pinions as well if Mike doesn't have what you need.

Quick quesion what are my size pinion options for my 7XL (for example mod 1) what pinion fits snug over the end of the motor

[squeeforever]

The size of the teeth have nothing to do with the fitment. The XL however, needs a pinion with a 5mm bore.

squeeforever i looked at my reply and realized i made a mistake i knew that the teeth size does not matter i was tring to say what kind of pinions fit on the inside of the pinion to the motor shaft but you answered that with 5mm thanks

[squeeforever]

No problem.

Why is the grub screw coming out? It's no surprise that solder didn't work as you'd have to heat the pinion and screw up enough to have the solder bond well, and even then it won't be the best. Not to mention the solder won't bond to the grub screw. Have you tried loctite? How much "meat" is there for the grub screw to grab into?

He said he bored out the middle like CF does and tryed super glue

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

will 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?
