TT Electric vs NF Nitro, insane

I just put a couple of laps on my new NF nitro. WOW! It has a NR .12 in it and I cant believe how fast the damm thing is. Can a brushless set up get up to speed as quick as a nitro bike and hang with it?

The stock brake unit doesn't work very well. The set up up seems to load up the throttle brake servo, isnt that bad as far as excessive current draw on the RX pack. Any suggestions on making this thing stop better?

Brushless won't ever get up to the speed of a nitro, but it will easily out manouvre it around a track (unless the track is an oval)
You need the rear brake aswell to get better stopping power, or as Ron says, get the ultimate setup, Pat's brakes!

I think the only reason a nitro can't hang on track with an electric is the clutch vs direct drive. Or, at least that's the biggest part.
That right John?

As a long time car racer, I would say that you need to look at the clutch. On my T-Maxx, I changed out the composite clutch shoes for aluminum ones (RCBoyz.com) and it made a difference between wheelies and no wheelies.

For my on-road racers, I only use Centax-Type clutches. These clutches are really cool, because you can control the time that it takes for the clutch to engage. On my on-road cars, I like the engine to rev a bit before the clutch engages, but for a motorcycle - since you don't want to spin the rear tire, so you'll set it to engage right away (which makes it "closer" to direct drive).

I am partial to Mugen for the clutch, and you should be able to pick one up for around $50 or so...and if you're gonna do that...well, I'd grab the MTX-3 2-speed assembly as well! It's all about gearing, and you CAN make a nitro vehicle get around a technical track as well or faster than electric if you're willing to play around with the clutch and gear ratios.

BTW-How much money do you have invested in the bike as it is now? (I'm really thinking about getting one - right now I have a new HOR bike, which is fun...but too quiet for a nitro guy..)

Thanks,
Mark

I did experiment with a centax which I borrowed from my Impulse when I tried the 2-speed box and found it to be no advantage. The existing clutch engages at slow speed anyway, all I could do with the centax was see what a later engagement would do and it just makes it more difficult to drive around hairpins. Main track difference I've found between nitro and electric is the weight distribution. It's just that bit harder to keep a line on slow to medium corners. Also powering out of the turn needs more precision and you tend to err on the slow side, too much throttle too early will easily have the bike in a tumble. Maximum lean angle is also less on nitro. Torque from low revs is much less than electric too. All this means an electric bike will outbrake, out corner and out accelerate out of the corner any nitro. Have a look at the Mendip vids on the Skippy site and you'll see what I mean. The nitro was easy handling and fast on the fast parts of the track, but felt like a fish out of water on the slower parts.

Thanks for the replies. My bike (NF) nitro is all stock. The brakes are the only thing I would upgrade. Ive been playing around with my DUC tt for the last 3 months. I love it. I can run the machine without crash bars. I dunno, Ive been flying helicopters the last 13 years, maybe it helps.

The Nitro is so damm fast I cant believe it. So far, the cornering entering and exiting is somewhat similar to the TT. The only thing is is that the power comes on so strong and so quickly. Gearing down would help, either that, or lots more practice.

Hope to see some of you at US race events. Im hooked for good.

What US race events? Other than the California group, there isn't a thing going on race-wise for us US guys.

We need to get organized to get a race going on the East Coast. I don't want to wait another 10 months to go out to Vegas again. Any East Coasters interested in finding a track and setting up a get together/race weekend? Hopefully before winter comes around again.

Why not? Brushless spins over 50,000 rpms. I think the nitros spin somewhere in the 30's. Nitro isn't more speed, just cheaper speed.

I would love to try a Centax clutch on the stroker but can't right now due to the halfmoon key in the crank where the flywheel goes. Makes it hard to custom make a proper flywheel.
I'm stuck with the 2 shoe for a bit so I think I'll try some alum t-max shoes.
For 2 shoe setups does anyone know if lighter or heavier springs are available so they allow shoes to engage a bit sooner later?

Hey Drillah, have you seen the 3 shoe clutch for the NF, what advantage would there be in using a 3 shoe clutch????

(dammit!!! I can't find the pics )

Who makes after market parts for the TT Ducati 999R? Got my first bike yesterday and hope to get a chance to give it a try later today after I finish working on 1/5 scale F1.

Yeah i've seen it. my flywheel is only setup for a 2 shoe config. The flywheel mounts differently than most, it does not use a tapered collet. The shaft does not allow me to use any-old flywheel. I gots ta make one
