Hello everyone,
I'm brand new to this so please bear with me. I just started racing again after 15 years and I'm starting to take things seriously. I have had some terrific help from the local racers but i have some tech questions. First is about gearing I understand the ratio formula but my question is how does spur size effect speed? If I ask about gearing (I'm running LRP Sphere with Novak 13.5 Brushless) at my local track I am told run 4.8 or 5.0 final drive. O.K. but do I do it using a 72 tooth (48 pitch) spur or 87 tooth? I know a larger spur with smaller pinion helps acceleration but lowers top speed and neutral size pinion and spur will effect top end, and I know it depends on track lay out (Our local track is pretty good size with high and medium speed corners) but I'm going to a new track in Marin and I'm told it's smaller and tighter. I just want to get a close baseline so I'm not changing pinions after every heat. Thanks for helping this newbie out!

Whats up Jay!Its John from Norcal.Run your motor at 4.7 ratio and you should be fine.I have not even looked at my kit yet,but however you achieve this gearing which I believe can be done with the stock spur,make sure your around that number for Marin RC.I hope to have my car ready for Marin this weekend.We'll see.

Tech Regular
87 tooth spur is what comes with the kit. 87-37=4.7 or 78-33=4.72

Thanks from newbie~
Thanks everyone for the reply's on gearing. I'm usually stuck to Lex like glue for info but he won't be at Marin on sat he's racing at the San Jose G.P.
Big John thanks for the ratio info! You get that TC5 built and Lex will be looking over his shoulder more often!

i just got my tc5 and just started building it, the first step is to build the four shocks, should the black seal retainer be very tight to go in and just pull the shock rod so it stays at the bottom? should the whole shock assembly be very loose and free while moving it with my fingers or a little tight?? i dont no what to do i need a little help if anyone can give some feedback..
thanks
Mike
