I used to try 38, temperature was around 150-160, changed it down because the straight way is not long enough for the top speed, and I was struggle with low/mid speed acceleration.

I'm using 35 and it's good. Temp is around 130F.

I'm still rookie with electric motors, perhaps our outdoor track isn't grippy enough?

I was running on a very small indoor carpet track last year. I had to go with a 21 or 22 pinion. This year the track is 20 feet longer and I was maxing out halfway down the straight. I'm thinking 26 to 30 is about the right range. With a 25 I was @ 110 or so after 8 minutes and still topping out a little early

McKune came out a week before the Exotek. Sadly Troy stopped making them. The McKune FGX finished second at last years carpet nats.

Our vinyl wing decal kits have gone out to the printer for the FGX, I'll post pictures when they come in! Hopefully shipping no later than Tuesday next week!

Default FGX Project

After racing the fgx on carpet I have found that for the size of the tracks I run on the car is just not fast enough to compete against the DD cars, It handles fine but the straight away speed is lacking, so I am working on a little something. I cobled some spare parts together to make the mock up and I will be having some real parts made. I am currently working on cad drawings for the new design. Here is what I am doing.

A couple of those were done last year, but a kit was never produced. It would be nice if an actual production belt system was available.

TQRCracing described how to put an F104 front end on the F113. I think I saw it here on RC Tech, but you may find it at www.tqrcracing.com as well.

The mod to fit the F103 front end is the same as the F104, shave the chassis inserts and bolt it down. I'm guessing you have a fixed sliding kingpin rule?

None of my mods showed drastic improvement. Re-gearing didn't show enough additional pace. On a long flowing track where this car doesn't have to slow down too much or where open motors are used, this car will be a gem. With 21.5 restricted timing on a twisty carpet track, I'm afraid this car just doesn't have it when geared where it should be. I ran 2 heats with the FGX yesterday. It drove great, perfect traction, ball diff was flawless, but just couldn't hold a candle to the F104 V2 guys on acceleration. So I put down the F1R and ran faster. Same brand Electronics and motor in both cars. Same timing, same gearing @ roughly 3.0 and it was night and day. I am going back to DD for indoors. Sad, but true.
