fx5 is not a legal motor... another newbee motor:D
but hey, anything to get advantage right:D
they won't know:D

Yeah.... what ever you called it, I have few boring legal motors like NSR12 S5 , RR12 L5, FX3,5 that are sleeping in tool box and only wake up on race day. The rest of calendar I'm having fun with more fun engines like V12, NS15 mod, and soon MX15 P7. Chasing friends or top speed racing at long straight, and we enjoy this hobby at top speed.

......btw, newbees don't cheat during national race, we use those boring motors above to earn honest lap one by one.

:D :D :D

Hey Scott,

Where might one find a Nova NSR 12 hotmod?

Thanks and great review!

I would call Fusion motorsports and ask jim as he is Mr. Hotmod. Tell him I sent you. He will be able to tell you where to purchase the novarossi hotmods. FYI: Fusion motorsports is the US importer for Novarossi. Jim Hottinger is the owner. He is the Hot part of the hotmod.

hi

i am new...

was wondering what width tires i buy for my mtx3? also is there a offset i have to consider?

thanks:tire:

I am assuming that you are running foam tires. Use 26mm for the front and use 30mm for the rear.

First, you could just purchase Fast Brand of tires on the spoked wheels. The wheels are made by Mugen and work perfectly on the MTX-3. If you purchase another brand, most people will tell you to purchase 2 degree offset. I am going to say use the 0 degree. What I have actually found is that the 2 degrees make the car so wide, that you can't get it to a legal width for racing. The 0 degree wheels you just have to space out the wheels a little.

If using GQ tires, get the zero degree wheels... you can get them from competion rc or winners circle.

Other choice would be to use Fast tires. Get these from Ace Hobbies... right now the price is buy any 3 and get a 4th for free.

Other people will recommend other tires, these are the ones I have tried and would advise for a new guy with an MTX-3.

Another economical choice would be twister tires, but I have not run them. I am sure they would be fine as well. All of these are good quality race tires.

thanks fish.

so is there handling difference between the 0 off set and 2mm offset? i asume 0 would be more twitchy steering.
:tire:

There would be a difference in handling if you do not adjust the width of your car accordingly.

For example:

When I run Fast tires on the mugen wheel (spoked, not dished) and I put my car on the setup board and set it up, I usually set the car width to 198-199 in the front, and 199-200 in the rear.

If I switch to GQ tires with the zero offset, the car gets about 1.5mm narrower, so you unscrew the pillow balls in order to get the car to the proper width. You of course also have to adjust the rear camber links and the front steering as well, which gets to be a pain.

Hope the above part answered your question.
Below is further clarification of my earlier post.
If you were instead to put on the GQ 2 degree offset, the car gets about 3 mm wider. The problem with them is even with the pillow balls all the way in the car is still to wide.

instead of unsrewing the pivot balls when running tires with 0 offset, put a 2mm spacer behing the pin and in front of the hub. also, if you ran 1 degree offset tires, you just need to add a 1mm spacer. hope this helps.

this will work for a quick fix. but i like fisher's idea better. putting spacers will make the wheel and hex contact patch smaller that may make the wheel break easily. just my opinion though

Gears
 

Hello everybody....

Long time since my last post...

I'm having problems with my 52tgear...
1st: I do know how to set gear Mesh

I'm using 58t 1st gear...

When I get the 52t, it doesnt last a single qualifier, last time not even a couple of laps...
But When I use the 54t, no problems at all....

Maybe with a longer gear ratio the gear change punch is higher?
Anybody got any clues?

Re: Gears
 

What pinions do you have in your clutch??

I can see you have a difference of 6 teeth between spurs, and ideally you should have the same difference in teeth between clutch pinions.

AFM

There is a difference in 5 teeth between the pinions...

But this difference is a must... The track I race has a 290~300ft straightway



Just something, beyond that, I don't remember for sure:
The A Ackerman gives me the most steering of all, doesnt it?

on a track like that i run: 20 27 pinions and 60 52 spur
