Brent,

What you have looks good. You have always done well with the shaft drives (CD3, LD3). That layout looks similar to the Walbern chassis, so you may no have to re-invent the wheel on that part. It does look like more rotating mass than the belt drive, but you definitly have the power to pull it with those new mills you just picked up, or that nasty .28.

Hope to get to meet you this race season. I will be putting more time and cash in this year if IMDRA stays around. It will be a lot of fellas after B & E's racing title.

Thanks nitrorevo. The chassis has a little of Walbern layout but NOTHING matches at all from a Walbern chassis since the engine is turned differently and the diff case. The rotating mass of the diff is less than the large 40 tooth rear pulley and long belt plus this is all 1/10th scale parts to save weight anyways. What my thinking/thoughts are is that a big block .21 can pull these gears and they last a good while since the drag chassis is 2.5 lbs. race ready and a CD3 is about 4 lbs.

The engine that you see is one of my brand new Kangaroo's that Rick modded a few weeks ago while my other Kangaroo is on the Walbern chassis Pro-Mod. The new R03 and R07 both JP modded but then Rick did his other mods for drag timing and a secondary set of boost ports and he swears that these engines are stronger than the Kangaroos so we'll see. I'm loaded with engines now. I have 2 Xeonon's, 2 Kangaroo's, 1 JP R03, 1 JP R07 and 2 P3 .28 engines. All are RBmods and Rick says that my .28 will without a doubt compete with the .21's so we'll see this year because I will test it ALOT. I've got alot of neat parts that Rick has made me to test and I can't wait.

Yeah B&E got some things to iron out too. We talk damn near everyday and they too are having Rick to do some new engines for them since they won the '09 Championship using Rick's Kangaroo and Cordoba.

Hope to definately see you out this year too man. It'll be great to meet alot of guys from here at the tracks.

nitrohead, the rear diff has a one-way with a solid shaft that will go thru it and it has reciever grooves for c-clips to keep the axle from going side to side. In the photo, it just isn't installed as I don't have the axle(s) back from being cut down to fit the one-way bearing and also I have to drill a hole all the way thru the one-way and lock the shaft so the brake will work otherwise without locking it the brake won't stop the car = not good.
