"Unbalanced situation of the motor mount exists as F103GT inherits the weakness of F103."
"Putting the cooling fan on the left improves the unbalanced and overheated situation."
"With this aluminum motor mount, the center of gravity is low enough for the F103GT to run fast and stable."


That's all I got to say about that!

Default Nice Wheel conversion for F201>F103 usage.

I think of the F103 GT continues to show strength then maybe we wil see another body soon and maybe even a return or upgraded version to create a decent f-1 car again, not that the F-201 was bad it just wasn't a proper scale model being 4WD amongst other things.
Clever conversion for those looking to run the F103GT as an F1 car again:

There is 1 problem of Tamiya bodies (they are the best mold bodies...hands down) All their bodies mounting holes are pre-drilled to fit the specific chassis...like some bodies are for TA05 some are for TB02....etc. I am not 100% those bodies you have mentioned above are all pre-drilled but you have to concern about your F103GT might need to have some special mounting post that will fit those holes or you will have to drill 4 new holes and cover the pre-drilled one.

About the shocks.........get the TRF one.

If you bought the Kit sans Courage Body then many of the Tamniya TC bodies will fit without modification as the original F-103GT kit was designed to be used on a TC body.

I would stay with the TRF Tamiya shock as they jhave proven the be the industry leader in on-road shock design.

If you look in the pits at Reedy their are even several drivers from other makes running Tamiya shocks on their non Tamiya chassis as they are that much better.

The F103GT uses the most standard size motor, which is a 540. The same size 1/10 touring, buggies, etc.. use. I belive the kit comes with a Tamiya Silver Can Motor, which is a run till it dies motor (no maintinance) but if this is your first electric it is a good place to start, I too went from Nitro to Electric, and that is how I started. All of the top motor makers make this size motor i.e. Orion, Checkpoint, Team Brood, and so on. As for the batteries, if you are going to run the stock kit, it calls for a stick pack, you will want to go with a 4200 cell, I would buy an already made pack, instead of having to fool around with trying to build one, but thats me. Your local track or hs should have some in stock.

What is needed to convert the F103GT to F1?
Nevermind, I found my answers!

Ok, what hopups would you recommend / or are needed to be competitive in the TCS races? Also, what tire / insert combo works best on an lightly prepped asphalt track?

Thanks, I'm really digging these cars.

Sorry I just read the rules for that class, I am use to Touring class where there are a ton of different rules for each different motor, looks like the F103gt only allows silvercan motors, any tamiya hop up etc. My opinion upgrade to the trf damper, the aluminum motor mount, some of the carbon chassis parts, it all depends on what you want to spend. But if you want to race in the TCS it all had better be Tamiya parts

Still building the F103GT and I have couple questions...

(1) what # of holes are ppl using on TRF shocks for indoor carpet track..? 2 or 3..? Or 1 hole...?

(2) Resolved......thanks

(3) On the front, manuel said there should be a spacer on the bottom and 1 above on the steering knuckle...however, my ride height ended up only 3.5mm above ground...should I remove the lower spacer and place it ABOVE and raise the front ride height to 4-5mm...? Is that the right way to do..?

(4) I have the optional 64P spur gears from Tamiya, it came with 2 different size, 1 large and 1 smaller....which 1 I should use if I am running the F103GT wtih SILVAR CAN (Johnson) motor...? I am running her on carpet (trackside) and I just want to prep the right spur, and I want to ask you guys first before I have to test both...cause I doubt I have time to TEST both, barely have enough time to build the car, and probably the virgin run of the car will be the 1st qualifier....so I hope I am installing the right spur...
What pinion I should use too...? 24T?

Thanks in advance...

Well, I don't know anything about carpet and your gearing really depends on your track, but in response to #3, yes, you should flip the spacer up to the top of the knuckle and raise the ride height.

Solara,

I race my 103 on a small carpet track with the silver can motor and here is what works for me:
1 hole piston in the shock with 30wt oil.
With the metric 64 pitch gears, start with a 22/94 (small spur gear) and adjust according to your track size.
Because the car has so much steering, we replace the front springs with fuel tubing, essentially locking the front suspension from moving. You can also add washers under the springs to make it stiffer. Whatever you decide to do, the front end needs to be stiff.

Good luck.
