It's an X12 (I think by Ofna). Last night (I think I am in a different time zone from most of you!) I basically rebuilt the rear of the car. I put about 13mm of fuel tubing between the brake pads and put the screws through. This (thanks ziggy) sorted the brake issues ...fantastic!
The servo arm problem was mostly caused by me using the wrong ball ends on the servo link and servo arm. Basically, I used the ones that were intended for the rear shocks which, as you know, are MUCH larger than the correct ones. This obviously restricted the amount of space I had to work with. Now I am, still with a bit of difficulty, able to clip the ball cup into place with the use of long nose pliers (through the hole on the graphite upper).
About the manifold problem - I searched through previous posts from as far back as 2004 and even back then this was a problem! So I have decided to follow your advice and file 1mm off the bottom edge. Thank the rc gods I bought a dremel tool with my car
Anyway, gents, I am now within days of putting her down and breaking that fire-breathing engine in. Soon I will hopefully put down some laps in anger. Can't wait to experience what most you have spoken about on this forum ...a real honour to join the club!!
BTW: Though I intend heat cycling the engine (Novarosi NS12S3) through about 5 tanks, I have heard from the people at the LHS that competition engines will do better if they have a 10 tank break in ...is this true? I have an RTR and I only put that through 4 tanks of heat clycling and the motor is still running strong (after something like 5 galons).
