Are you running under any rules?

if not.

1. 540 Motor
Team Powers super lite motors. 140grams standard.
www.team-powers.com

Cheaper option. If you put a EZrun in a lathe and do away the cooling ribs it can go down to 15Xgrams. Don`t do the ends as they are glued.

2. 380 motor

Supports standard pinions but it probably needs a new motor mount. 72grams.
http://v2.teamnovak.com/products/ind...products_id=28

That and a 2s-3s flight pack and your way down in weight.

This might be possible to do on a Tamiya F1 due to the RM-01 chassie parts.

3.
Next then is a 1/12 servo

Thanks for all the tips. Yes, rules that I crafted (as I was the race organizer).

I have done it. Seems to free things up a little. I think I may have picked up a tenth of a second by removing the shields. You will have to stay on top of your bearing cleaning though because they will get dirty fast. I actually prefer to pull one shield off and run the unprotected side where it is less exposed to the dirt and grit. Ex. the outer front wheel bearing is shielded by the tire and unshielded inside the steering knuckle.

Any shorty on the ROAR list is legal. All of mine are and with 21.5 I get a half an hour of run time out of a 3800 60C.

Yesterday during the practice before the race, the right front wheel came off and I thought I had a broken knuckle arm. But it turned out to be a failed wheel bearing. The inner bearing had completely disintegrated. But I had a metal bushing to

But the FGX survived a qualifying heat with no damages yesterday!! The car performed well.

I received the new Exotek chassis yesterday and I am installing it now.

I am in the process of installing the exotek chassis and the rear battery stop doesn't work for me at all.
I have the shorty pack all the way to the front (to give the car more steering) without running into the steering post and where I need to put the back stop, there is no hole. It would be nice to have a slot for forward battery position...

Also the spur gear cover piece's bottom screw hole doesn't line up.

After following the tips from my last question I got my fgx to turn a bit better.
But it's still 1 second slower on every lap compared to f104's on our track.

Would shorty (I have huge 6000mah 2s currently), better traction combound (F104's are using something better than I have) and exotek chassis probably shave that 1 second of my laps?

A shorty mounted forward will help your steering even more, as will the weight reduction.
EFX chassis definitely helps durability IMO. A full second is a LOT to gain though.

You need to look at drivetrain efficiency if you haven't already

Does the Exotec chassi allows the IFS system?

Not out of the box but check out our build of the IFS for the standard chassis and the same kit installed on an Exotek chassis with a few modifications to make it fit. Build info here.

Happy New Year!!

Mike has one coming out mid month next month and will work on his V1 and V2 chassis.

How are you geared? Check your FDR. I try to keep mine between 4.5 and 4.0 or else I run into heat issues. This is much different than the F104s which run around 3.0 to 2.5. They are 200g lighter, so it does make a difference to your motor to not gear like them. I run a shorty mounted forward and have no steering issues (unless I don't clean my front tires) or run time problems. I also run the 35g 1* camber plate to keep the nose down. How much droop front and rear. I try to keep the rear around 2mm and the front at .5mm. Last track was a 90 foot straight and a technical infield. The car was geared wrong, tweaked and too stiff and I was only tenths off the fast lap. Last question, how much drag brake? I run about 20%. I feel it makes the rear rotate better in a tight corner.
