yeah my car wants to bounce when landing in the rear, threw 20 grams of weight in front of the sideways lipo and it seems to have helped, I'm going to try AE white rear springs (2.00), and soften up the oil in the rear, hope I can eliminate the bounce, I know landing better downsiding will help, but I'm not Lee Martin, and sometimes I overshoot a jump, especially when chased. On the positive side, the acceleration with this car is Amazing.

gotcha, we don't have such rules, all of the pros charge with the lipos in their cars all the time, no penalty unless its over default voltage.

I'm new to the yz4 and bought a nice used one. When I removed the rear tranny case 2 1mm shims fell out. Any idea where they go and if so what are they for?

Normally leave the battery in the car. Drive another car while one is on the charger.

I would call amain and ask them. the more people that call and ask the more likely they will order them. I think there's 4 different rear arms that can fit, yz2 arms, s4, bmax4, and L5. I got a yz2 front bumper to fit on my yz4 by making a notch in the rear of the front hanger.... so much nicer when the front bottoms out it hits the back edge of the bumper instead of the back of the arms and hanger

I wish amain would carry the flexdeck Z4-003-MR33 . That thing looks nice !!

Order one from LMR Racing, it's the same part & I dare say Lee will post to the States

Makes the car even easier to drive.

You may also want to check out Berzerk RC from Australia. They have two to deck designs and will ship to the States. I'd also suggest picking up their YZ-4 lipo mounts. Got two decks and lipo mounts shipped to the States for not much. Shipping was $10 AUD which is about $7 USD.

Amain has the b4-011r 5mm hexes. Z4-630 isn't the aluminum pulley, it's the plastic pulley set. Can you recheck that?

I'll look into the other parts. Thanks for the list.

Trying to get a 1.2mm rear sway hooked up. What are you guy using to hold the sway in place?

(2) 3x8mm Flat Head Screw (2) Countersunk Washer . Had to mount mine inboard as the bar is not long enough to reach when installed on the backside .

I was wonder about mounting the swaybar on the back, but if its too short oh well, just kind of a pain to get to it. I doubt I will change much from 1.2 in the rear anyways. Car is a beast.
