The only issue I have had are building shocks consistently with the correct rebound. That seems to be the tricky part. I am sure with some practice they will be as easy as the Tamiya shocks that I have been running on the old car. Any suggestions on getting consistent rebound in the shocks?

Btw, you forgot about that Hodapp guy. Sup' DUMAS!

the only prob that i have had with the shock, is the leaking issue, i used to rebuild them every other day. no matter what i tried, they always leaked from the shaft. Korgae Scales pointed me in the right direction, on how to build the perfect shock everytime. thanx Korgae (can west R/C)

I found it difficult to screw on the shock caps without cross threading. Also, and I'm not sure if the two are related but, my shocks leaked like crazy. Had to rebuild them after every other race. I haven't had leak issues since I bought the aluminum shock bodies but the ones I got weren't smooth. There were high spots inside the bodies that caused the piston to bind slightly as it moved through the shock. The amount of binding varied between the four shocks.

I've never had a performance issue with the stock shocks, but building them with equal rebound has always been an issue for me. I spent the better part of 2 hours building them in preparation for the Novak race this past January before I was satisfied with them. The shocks have always gone together well, and I've not had leakage issues with them (no worse than any other shock I've tried) but I dread rebuilding the ones I've got now.

I printed out Peter Robinson's recomendations for building them so we'll see how that works.

I have said it once, and I will say it again. The Plastic shocks that come with the kit are the best shocks for the XRAY. Super smooth and if built correctly they do not leak.Time and time again I have outperformed metal shock bodies and serpent shock buyers, hands down. Please follow the directions closely you will be pleased, give them a chance.

The metal shock bodies require a little more attention, if you use them you have to make sure you use an xacto knife to get all the nipples off the piston, if not the nipples will rub againt the inside of the bodies and your shocks will be inconsistant, I have found the metal shocks to be a waste of money I could have spent $30 dollars on something else, right along with the serpent shocks. This is my opinion only and nothing against metal or serpent shock buyers. But performance outweights looks in all aspects of RC. Fact: The plastic shocks have put me on the podium every single time.

I cant believe how many post there have been about XRAY shocks. Will this ever end? We will have to wait and see.

Thats the only reason I put Tamiya Shocks on my car. They never feel the same. Believe me the Tamiya shocks definatley work on the xray, but it took me trying a lot of different parts to get them to be the right length and whatnot.

Peeps here is a direct quote from Peter Robinson to me on how to build X-ray shocks, and it works great. Ever since following these instructions I have had no problems at all with my shocks.

Thank you Peter!!

1. put the bladders in the caps.
2. make sure the pistons are 4 holes open.
3. fill shock with oil.
4. pump the piston slowly up and down to get bubbles out.
5. wait a couple minutes.
6. push the pistons half way up so the oil in the body makes a little dome.
7. slowly screw the cap on.
8. wipe the oil and check the rebound, they should fully rebound, but slowly.
9. if you cant push the piston in, or they rebound too quick, crack the seal on the bottom of the shock (while holding the shock upside down) and push the shaft in, twist the cap back on, check the rebound again.
10. repeat step nine until all the shocks are the same. make sure the shocks are all 70.3-4mm, and your dialed

Its on page 148 also

Default shocks?

define good? I have had my JRX-S shocks on my TC4 and now my Xray for over six months. I took them apart for the first time and they were still perfect, no air bubbles, oil was clean and they all still rebound perfectly the same. That is what I call good. Building shocks every two three weeks, no thanks.

Thanks john, I have a 30 Tooth in it now, if thats too hot I'll make adjustments. The Brood race is at Mimi's on Sat and I have 2 new Experss motors and 2 "Extreme" stock packs. I couldnt believe the voltage these things were coming off at. I can't wait for people to ask, "what the hell you got in that thang?"-
