Sorry guys, but I guess I am a traitor.
I have retired the Tamiya F103GT, and replaced it with the Calandra Gen X 10
I have found with the same motor and electrics I can gear up from the Tamiya's 28/100 gearing to 28/90, so top speed is faster, and first time out I improved my personal best time at my track from 18:304 to 19:306

Nothing wrong with going to World GT; all of those cars are awesome (though personally, I prefer the BMI DB10R).

The F103GT is still a great car. So versatile. Not surprised you could gear the CRC taller - it runs on four cells and is therefore lighter! The 103GT does need low gearing though - probably due to the weight in the right hub (and taller tires).

Our club rules are not World GT rules.
We have our GT3 rules that allow 7.4v LiPo but is restricted to the HPI Saturn 20T motor, #1136
Car weights in at 1106g with an HPI Honda NSX shell

Default F103GT

Hey guys,

I just got a F103GT and was wondering about gearing (spur / pinion) with different motors.

540 Silver Can -
Tamiya Sports Tuned -
27t -
17.5 brushless -

540 start with about 4.4 (72/16) and adjust for track size. The Sports tuned generally likes a tooth less than the silver can but 72/16 isn't overdoing it so you could even start there.

For a CO27 Monster stock 72/14 and go to 72/15 is it isn't hot after five-minutes. Gearing depends on the type of stock motor (more than track size) though. If your cells are up to it, this will go seriously quick down a long (60m) straight.

These are for rubber tires.

17.5 no idea. I'd guess a massive pinion though...

17.5 is like an 88/27 if you run 64p for a real tight high grip carpet. If its real wide open and flowing, Try a 32 or 33 and temp it after each run. I've run an 88/40, but that was overkill for top end.

Default WTB: 0.4 module spur gear 104 tooth.

Does any one want to sell 104T 0.4 spur gear? It is the larger of the two that come in the bag... Anyone?

Default Setup Guide

Hey guys, Ben from Australia here.

Is there a good setup manual or web site for the F103?

I used to have an F103GT with the 3Racing motor cage. I just wanted to warn you, go with a pinion with fewer than 19 teeth. I had a 19t pinion with the stock spur gear and it just barely fit. Great car.
