Sorry but do not understand. Thanks for your help.

Hey guys i'm looking to build an FT kit for the 17.5 "boosted" class. I want to run a MMP since I have another I use in my SC10 4x4 and would like to have a backup for either. What would be a good sensorless motor to use?

Dunno about sensorless but I am running a MMP and just picked up a Trinity D3 17.5. It comes highly rated by most of the guys at my track. If you really wanna go sensorless, perhaps try Revtech???

i read the sonic reedy motors are good, ik that a bud of mine uses rev tech in all cars and he loves it in the sc10 it runs well.

Viper for me has been really great. They run cooler than most but with more power but the power band is soft. Good brakes,

MY NOVAK used to run 150 after main with the same gearing on viper it ran 30 degrees color.=] and it just worked. So basically 17.5 trinity motors, reedy,viper..thats all i can recommend bc ik people are very happy with them.

Thanks. A motor that can run both as sensor & sensorless would be ideal. These are the specs I need to meet:

The magnet length shall be 25.0 +/- 1.00mm not including any nonmagnetic balancing material. The magnet outside diameter shall be a maximum of 12.51 mm, no tolerance, for the entire length of the magnet. The shaft outside diameter, where the magnet is mounted, shall be 7.25 +/- 0.150mm for the entire length of the magnet. This dimension must be measurable without destroying the rotor.

No tire tread cutting, bald tires or custom cut tires allowed.
Body Specifications: Full fender truck body. Body must completely cover tires when viewed from above.
No add on or integrated spoilers/wings allowed.
Tire Mounted: Minimum Diameter of the tire (mounted) is established to limit extremely low profile designs. The target dimension (new tire) is established at 4.30 inches. To compensate for wear, molding tolerances, degradation of foam inserts, the pre- race minimum allowable diameter of a mounted tire is 4.20 inches.
No ribbed front tires are permitted.
Height: Minimum Overall Height is measured with vehicle at Static Stance in ready to race condition. Race vehicles must have front and rear bumpers.

Front Bumper can be no wider than the inner sidewall of the front tire when straight.

Nevermind, I think my hangover caused me to read that as "ROAR Sensorless Motors: :weird:

I'll probably go with the Tekin Redline. I have the pro4 in my 4x4 and it's been great.

Anyone running the LRP vector X12 17.5 spec motor?

This was an old post, does it still hold true? I want to interchange wheels between the SC10 an SC104x4 as I already have a few sets of protrac's for the 4x4

Thanks

Looking for some information on big bore springs. I know this thread is long and i couldnt find a setup for big bore springs. I would like to use the losi springs like i have on 44.1 but wondering what springs, oil, and pistons for the sc10?

Thanks,

They will fit.

Normally if you need a washer on the outside of the rim, either your bearings are worn/going out. the hex is worn on the inside by the bearing(stock AE plastics hec like to do this) or the rim is worn/thin around the hex.

my SC10 4x4 has had no problems fitting on working very well on my 2wd. no spacer on the outside needed.

funny was wondering what you meant LOL.

I got a Revtech 17.5 coming in I am going to try with a MMP. Heard they work well.

well my ball cups seemed to be wore out an want to upgrade to add durabilty wats the best way to do that

RPM ballcups or SC10 4x4 links and ball cups those are 3mm. Or you can go with dubro captured ends.

So who is liking the BB spring upgrade, is it helping to smooth out the ride over bumpy sections and jumps?

Anyone tried these?

[QUOTE=JEFFs SC10;10209979]RPM ballcups or SC10 4x4 links and ball cups those are 3mm. Or you can go with dubro captured ends.

witch one u thnk is the best ive tryed the rpm but they rub the front shock tower an heard bout the 4x4 wat i need to do to fit them on the truck an the dubro is wat i was thinking
