one way
Hey Blis was good to catch up and have a good look at the car, thanks for the engine mount it saved me a hole in the manifold and allowed me to finish trhat semi and final.
I was the only G4 RS 09 driver at the recent Queensland State Championships and i was very happy with the car. First time at this track with the G4 and i dialed in the chassis straight away. I was only .3-.4 off the fastest guys in the final and i believe without the gear box issues it could have been a lot more consistent and maybe a little faster..
My issues with the car:
1. I had the one way bearing jam in the first qualifier. I had lubed it with Hudy one way oil before the event. The bearing jammed and it looks to have crushed but i wasnt able to get it off the shaft to get a good look at it. Prior to this i was having inconsistent gear changes..started off shifting too late and then would change instantly and back and forth. I checked the play in the shoes after every run and tried both a small gap and a large gap but no change. My engine builders guess from experience is the faulty one way playing up the gear changed.
2. how do we get the jammed one way off?
3. The side belt rubs on the bottom of the manifold (short novarossi manifold and 2652 pipe). I had dremeled the bottom of the manifold off but the belt was still rubbing hard into the manifold. I modified the chassis to give the screw more clearance so the engine would sit further away and this helped. Then thanks to Blis we used the one piece (nots ure of brand) off his g4 which was 1mm taller and this gave some more clearance.
4. Play in the steering ackerman post. the black bushings that come in the kit look to be the wrong size with the inner hole about .5mm too big. Has anyone found any bearings that would fit?
Apart from these issues i think the car is awesome!

Servos
Plenty of servos in the market will work well with the car, it is very important that you get metal gear servos for the steering. here are some good servos you may use in you G4RS 09

Servo Futaba S9452 Digital High Speed/Torque Servo
Z8800T Digital High Torque Servo

When I put a front diff in without changing the rest of the settings the car started oversteering massively. Now I am using the TM blue ones front and turquoise ones in the back and the car feels much more stable

I tend to clean them after every meeting ... firstly with solvent then with 'T Cut' .. this is a slightly abrasive car paint restoring polish... It works wonders with a bit of elbow grease!
If I have a really dirty pipe I 'cook' it in a pan of anti freeze.

anyone run picco based engines in their g4s
Hi, i have a g4js which i picked up last year. I finally obtained everything i need to get the car running when i got my hands on a jl red dot. At the time I wasn't aware that picco's used smaller diameter crankshafts. I picked the engine up used so I do not have the collet which they normally come with. I tried the one for the nt1, the taper seems to match but it is still too big. I can't seem to find a picco one anywhere designed for the g4. Is there anyone that can tell me which collet they use? The one with the engine comes with or is there some aftermarket one that works well? Also would you guys advice against grinding the collet down to make it fit? I know it might be kind of out of place here but i think both models utilize the same collet. Thanks in advance for any help.
