Thanks to Juan at UGC for such a great product. And thanks to DickyT for all the setup and driving advice, lord knows i need it.

update- the white spring i was using for tt has been changed to gold, DickyT suggested my new shock positions and it helps alot. Keep the shocks more upright, not laid down. Thanks Richard
Update: 35T JP Warrior

Update: VP DH Procomps w/3 slugs on front
Vp SLW V1 w/ 1.5oz stick on weight on rear

Looks great man, I look forward to your feedback after some of the tuning we discussed and did tonight "thumbsup"

Thanks Richard, for all your help! I put it on the incline board in my garage, the tt is almost gone!!Good call on the shock position.

Damn its like "Pimp My Rig" twice for you lately! Love the blue panels. You gonna show us how you drive on sunday? I think you need the win!

do you know how steep it can go to, on my fastback i got up to 72 degrees before i started to tip back and i had to back back out.

looks awesome! i like that color of blue on the panels it matches the truck.

yeah im diggin the blue also."thumbsup" A win would be nice!

Sorry, i dont have anything to measure the incline. I just put the board up-test-tune-put the board steeper etc etc. you know how it goes? 72 deg sounds like a real good number"thumbsup"

I really like the wheels....Reflection did a great job on those!

Truck looks great, now where's the side by side videos?? I know Richard must have some sort of plan :mrgreen:

Thanks Juan, i really like the wheels too. I get alot of good comments about them. Whenever Richard wants to video, im ready! I know he is a little preoccupied right now with nats coming up. Thanks again for the chassis, im loving the "bodiless" design.

That's a non issue and we will have video done before then"thumbsup" It's the damn work schedule with 1/2 the team out. :evil:

what kind of weight are you running F & R? Why change the skins you got, they look great!

the weight is 12.8 oz fr/ 7.9oz rear. That is tire/wheel/foam complete. Rovers / nova dd foams. When i have to change the panels due to wear, then im getting some skins from Krawler Konceptz. They will still be blue though.Overall weight of the truck is 5.90lbs. (5 lb 14 1/2 oz)

What shocks are you running
 

I am pretty new at this. I have a bta similar to yours. My shocks are all in the way since I upgraded to VP knuckles. I was wondering what shocks you have. They look like they will solve my problem. The arm on the knuckles is much higher than the axial knuckles so I really don't mind having the steering set up on the front. Just feel like it is a waste of money not using it.

My shocks are Losi 4" comp shocks w/ cap mod. Bta is a big advantage, your approach angle opens up a lot of different lines when crawling. Maybe look at DickyT's build, i think he has vp knuckles. also maybe post a picture of your front setup. It makes it easier to give advice.

Looks good

That's the best you can do for your dad? "thumbsup"

Yes, until after you and he come in ahead of ME at the comp on sunday :flipoff:

I get no respect!

If you can get ahead of me this weekend, ill give you all the respect in the world :mrgreen:

had a bent axle, took it apart and found this, i have never broken a rear axle housing.

had a spare in my toolbox"thumbsup"
http://i946.photobucket.com/albums/a...build059-1.jpg

replacing axles with STRC S/S axles, alot beefier!!
http://i946.photobucket.com/albums/a...ckbuild056.jpg

added a bearing at the end of the housing for more support. Has anybody ever done this, or am i just wasting a bearing?
