Hi John,
I have been busy and haven't been on the compute lately. I've had to catch up on the thread and see you got a CRF engine. Good deal! Anyway, what type of glow ignitor are you using? I had the same experience with a variable power glow ignitor and it malfunctioned and started to burn up the element in the glow plug. All of the plugs showed no signs of carbon or other fouling, until further examination, the element in fact melted at the bottom. Good luck with your new engine, and I hope to check back later.

Here is my rebuilt GPX4 Pro with a new JLR Picco motor. This motor is absolutely fast.

The light blue front spring and shiny blue rear springs are from Hobao. Hobao offer their spring set:

Pink - Very Hard
light Blue - hard
Yellow - Medium
Shiny Blue - Soft

I actually run a front one-way and rear diff with 120,000 wt oil. As for the motor, there is plenty of power all the way through the rev band with max RPM emphasized. Since using this motor I've turned faster laps at my track.

Don't lie!!!!!!!!!!!!! You have destroyed the fast lap times....

Guys he went from 27 and 28 laps in 5 minutes to running a 32 laps pace in the main. He only slowed at the end because his fuel guy didn't fill it all the way and he had 2nd place about 10 feet in front of him.

Damn 350 you have that car and motor flying yesterday. I might just stay in retirement after seeing you performance on the track!!!!!

Great job 350!!!!!

Thanks 350 for info. I havent been looking hard enough as my catalogue ony has red spring,yellow and electric bue colour. A few members at the track are convincing me to go for G4S when I upgrade to Pro class but with results like yours im leaning back to GPX4. I currently have RTR version and with good set up last race broke my lap record by 0.8 sec. What were you racing against car wise?
