I WOULD USE A 8' BOARD...

IF YOU WANT TO,

JUST ASK THE BUILDER WHO IS LEADING THE

STOCK CLASS, MR. RAILHUGGER. HIM SELF.. ;D ;D

his opinion would be great.

your opinion would come with substantial weight as well !

i dont really have the room for an 8ft board ,so i was hoping do do a little math with my future tuning.

i am no physics guru for sure and this whole rail riding concept goes against what seems to be the right thing in my feeble little brain !

i am building a new pure stocker for june and would like a base line to try.

all opinions would be appreciated.

thanks to all in advance

The toughest part of railriding is finding your cars sweet spot, I've ran cars that were set up to pull 6" in 8 feet and I've built cars that only pull 2" in 8 feet and both were equally fast. center of gravity and center of mass play a major role in rail riding set-up as does track transition type. An aggressively rear weighted car may require a harder turn into the rail to stabilize the car where as a moderately rear weighted car may require less pull to the rail for a smooth run. The aggressively rear weighted car has more potential energy but has to ride the rail harder thus creating more rolling resistance , where as the moderately rear weighted car has less potential energy but requires less rail riding resulting in less rolling resistance. so the trick or "magic" if you will is finding the happy medium. And all of this is based on the assumption that you have good parts and good rear alignment.If you don't have a track to experiment on your best bet would be to build a couple of clone cars and run a different amount of pull on each and send them in to pddr and see what you come up with.I hope this helps more than it confuses and is only my opinion,I'm by no means an expert nor a pro, No college degree just some pipe welding certifications and a burning desire to squeeze every little bit of speed out of these little wood cars that I can.

MAN ! thats good stuff "railhugger " much thanks

can you expand on your statement about a rear weighted car needing to stabilize itself.
would that car be eratic at the curve ? thus needing a harder turn to correct itself.

i wish i had the talent to build a clone car , but every car ends up different in my shop !!

your cars prove that you are indeed a PRO

cant wait till june !
