can u get a replacement wing from the stock b4.2 i really like the wing and like that the front is not cut out for the shocks. i have look some but no luck.

When your shocks are not going up when on the car.....what is that? See video. Front work great but my rear I push down and does not go back up. Posted here since I also have had this issue on my B4.2 but can't remember what I did.

binding most likely. take the shocks off and compress them. also check the arm for binding.

you have hydrolock or binding. rebleed and try again

It's a Proline wing

checkout casper's thread on his, alot of info there about the caged thrust setup.

Washers are not grooved. It is easier to build a diff with the thrust caged and AVID offers 3 different ball hardness levels depending on the experience of the person building and the smoothness desired. While some stuff may be more bling, AVID definitely produces parts that are a very good upgrade to the stock components.

The avid thrusts are grooved just like casper's. I JUST built a diff with the ceramic one.

ah, ok. I know casper used the grooved ones. It was hard to tell from the pics, but I though it was grooved. good to know.

ok, belay that. You installed the avid thrust and it was grooved?

Yes.

Tungsten Carbide ball, this is what we recommend for most racers, the balls are more true than steel balls and slightly harder but still have a few imperfections which allows the ball to grab the the surface of the grooved rings easily

Anyway, after a few weeks of tuning with the centered electronics, I settled on the shelf. The traction and agility seemed to be in a good balance for my local tracks. It was slightly easier to get off balance in the air, but was also easily correctable. I hit a jump bad once and was on my side in the air, and was able to pull it back and land on all 4 wheels. Not something I practice, but was not hard. The bug was definitely mire stable with the standard mounted electronics, but i liked the transition steering with the inline.

Ae ceramic

Never wear out ,smooth ....

So far my ceramics have out lasted 6 sets of outdrives & transmission gears.

Haha, have you tried his balls dude...? I promise you, you womt be disappointed!
