Default Gearing questions

Hey guys, I have a question about gearing my car. I just picked it up and I'm about ready to run it for the first time. But I have no 64 pitch gears, so I'm about to order some. I just wanna make sure I buy the correct size pinion gears (and maybe a spur gear) so I'm not wasting money. I headed over to HB's site and seen that Barry Baker used a 64p 108 spur and a 37t pinion for a FDR of 6.33 with a 13.5 brushless motor for the KO Grand Prix 2009.

I will be running 13.5 as well so I am guessing I can just buy this spur and pinion and be good to go? I want to be able to play around with a few different size pinion gears incase my motor gets hot while racing. I don't know if 37t is on the high end or low end or in the middle tooth wise.

Would any of you Cyclone TC regulars help me out? What FDR should I be shooting for and what size gears can I get away with in the stock motor mount?

I'm not sure if this info will help or is needed, but we run on a med to high grip asphalt track that varies from technical to flowing depending on how the track directors feel like laying it out that Sunday. It measures 120' x 80' with a full 120' straight.

To anyone who has a answer for me, I really appreciate you taking the time to help me out.

Tony

On the stock motor mount you can fit 27T - 42T pinions with a 108T spur.

Your gearing is going to be severely affected by your speedo and it's settings. Not to mention, what 13.5 motor you're running. Some like a lot more or a lot less gear than others. Some are geared down in the 5's while others are up in the 8's.

are you sure?
because brushless motor mount is 2mm high, 2+2=4mm for all Diameter of spur gear...108T is 43,3mm, 111T is 44,7mm, but the maximum diameter of spur(43,3 + 4mm) is 47,3mm
or not?

I'm using a 116 and there looks like room for maybe 118.

I've never used the BL mount myself. Just going on what the HB guys have said before about the BL mount and what the HPI site says. It may have something to do with the fact that the largest HB spur is only 110. Another brands 111, 112 or larger may be able to squeeze in there fine.

110-111 spur using the brushless motor mount. 112 sticks thru the bottom of the chassis sli

ghtly. You can go slightly larger but it will stick out of the bottom and the other thing to look for is the spur gear hitting the rear FRP/graphite plate.

My 107 sticks out the bottom on the stock mount. I'm pushing a 9.-- final drive using the 16 tooth pulleys.

It's not a significant amount sticking out, but if you roll something over the chassis cut out, the spur will move.

Just used a header card and no movement. Did you use something with a straight edge?
