Nic Case - first in the 1.3 second range @96.99mph

It happened Saturday August 18th, at the MHRA's points race in San Bernadino Ca. Nic is the first RC drag racer in the 1.3 second range. He has this to say:

Thank You

Sometimes, being lucky pays-off ! LOL

Thanks for all the gracious help from the Jim Schauer ---(RAINMAN-YOU-DA-MAN).

Mark Rollings was in the other lane. And I have to say---- I don't thing I would have squeezed the trigger like that if I wasn't racing against Mark. He had the jump on me, and it felt like I was playing catch-up. When I went though the lights first---I was happy, just to WIN. But the record ET, was a real surprise! Thank You Mark , for making this old guy focus! LOL

The names are obviously wrong on the slip, but ,what the heck,------- it was a rush!
Brushless power & Lipoy's are KING. I'm very happy with my Grand Motor Sports dragster.

A Big Thanks to all the Good People with the MHRA. You guy's made it a --- fun, smooth program ,with a friendly atmosphere.smile

Records are made to Broken--------Who’s Next?

Video: tcolesen's HV Electric Savage Speed Run

Tcolesen posted some pics of his crazy fast electric Savage:

I attended the WFRCCC (I was the guy with the rock crawler, for those who saw it ), but I didn't bring anything. Now, I wish I had started on this project sooner so I could have challenged the guys in the MT class.

I had a Savage laying around for a good 8-10 months, collecting dust. The idea was that I would convert it to electric when I got the chance, so I did. Except this is a high-power electric! Here's what I did to the Savage:

-worked on the diffs, filled them with oil and set the mesh just about perfectly (very smooth, yet very strong), and installed the 4-spider gear setup with the HPI aluminum diff cups
-bought a Castle Creations HV-110 brushless airplane ESC (using a PiStix adapter for car use)
-bought a Feigao 540 12XL, and installed two Boca 5x11x5mm ceramic bearings
-hooked up and mounted 10s2p A123 (33v 4600mah, capable of 5HP peaks)
-made a completely custom center diff and motor mount
-rigged up a custom mechanical brake setup (Hyper 8 dual disks with HPI pads, custom linkages)
-custom mounted the steering and brake servos
-bought HPI Phaltline tires on wheels, belted the front tires with strapping tape, and reglued all of the tires (HPI can't glue worth a ****)
-installed HPI CVDs in the front

And here are the results:

Coolest transmitter mod you will ever see:

Matt Shumaker made these awesome mods for his transmitter. He modified his transmitter to accept a 9db antenna to improve range. He also modded the steering wheel to increase the travel of the steering wheel without minimizing the steering endpoints on the car. This significantly reduces how twitchy an rc car can get at high speeds:

Here are pics of my modified DX3. It is running a 9DB gain antenna and (obviously) a new steering assembly. The reason for the antenna is range. I get 1500 feet uninterupted with the antenna. The big mod, though is the steering assembly. The story behind the assembly is an interesting one. Basically, I have my top speed car setup for normal daily driving, I.E. good handling and neutral steering. However, when setup that way, over 100 mph the steering is far too touchy. I have tried expo and I do not like dual rates. What I really wanted is farther steering wheel throw to give me finer control at speed, but still have full steering lock. This steering assembly a 3 to 1 reduction ratio. That gives me 3 times farther steering wheel travel, though still fully controllable. I love it! Oh, another reason I made the steering wheel assembly is simply because I can. It is nice to have my own CNC machine shop.

The assembly is comprised of carbon fiber, machined aluminum and a ball bearing supported titanium shaft. The steering wheel is a pink compound Jaco L4 rear wheel that is narrowed and trued down.

Anyway, I know this is not exactly a mod that everyone will want. But, I made it from scratch with materials I have on hand from my heli business. So, it cost me nothing and solves an odd top speed issue in an interesting way.

At this point, this transmitter is perfect for my particular needs.

Oh, it is more comfortable with the wheel in its current location. I love it!

Video: Nic Case and his theory on flight

Nic Case's explanation of his takeoff during his run:

Flight Explination

On this video it's kind of hard to see what happened.

******So, what happened---anyway ?*******

Let me describe the track conditions first.....

When we arrived at the track, the first thing we did was check the traction level of the track. At 7am, I would describe it as ~ about as slick as a slightly dirt garage floor. (That’s Slick). But that’s ok because the track manager was right on top of it. He was willing to sweep the track & put down as much "VHT" as RCCA would want. (VHT-[I don’t know what the acronym means] is track preparation fluid sprayed on the track--it is very sticky)

RCCA decided to sweep the track and lay down a 10' wide strip of VHT. A well thought out compromise.
This way if someone did not want to run on the VHT surface, they had that option---Cool---

RCCA set-up there timing equipment in the far lane (this created a lot of foot traffic on the track) Including myself...LOL

There was some wind, but it wasn't terrible......

The glare for the sun on the track, limited how far a driver could see the car--and as a result, quicker acceleration was needed.

+++++It all added up to a big challenge+++++

.......Back to what happed......
I got a fairly decent ramp up to speed. It felt like it just about ready to really launch right about where the timing tent was. I theorize that the tires hit a slick spot(probably created from all the foot traffic)---the tires stated to spin-----grabbed traction on the "other" side---tore the tire into shreds---immediately the car got sideways---caught air -----and, well, you can see the rest,,,LOL

This all happed very fast and is hard to see on this video.(TRCZ, The R/C Zone did a great job of the Live coverage) Perhaps there is another video out there?

Cheers
Nic Case

Info on Novak's 118 mph Xray sedan

This is from Charlie talking about Team Novak's high speed car:

BIG THANKS to the R/C Car Action Crew for putting this whole thing together. Had a great time again, and hope this stays a long time tradition.

If anyone has any specific questions about the stuff the Novak Camp Ran please let me know directly charlie@teamnovak.com, or tech@teamnovak.com.

Here's the basics though:
Xray T2 Sedan
(2) Max Amps 7.4V 4000 mah Packs
(1) Novak HV 4.5 ESC and Motor
Kimbrough 88 Spur
PRS 50 Pinion
This setup was good for a very easy 105 repeatedly.

Anyone could walk into a hobby shop and build themselves one of these and run it all day long with no major problems.

The Following Setup IS NOT RECOMMENDED
Same basic setup as above, simply with different packs. We used 1 2S, and 1 3S pack connected to the HV. This makes for 5S total. This setup was good for 108, 118, 108, 116 in that order. Each time the car could make 2 passes , but something would "happen" on the 3rd pass causing a crash, or airborne car. Again, this is NOT RECOMMENDED.

I had another car with even more "gear" on it, but we crashed that during shake down runs and damaged it beyond repair. This car had a specially modified ESC, but we never got a chance to "up the voltage".

Bob ran a Kyosho 777 buggy with a HV 4.5 pass 60mph, then we did some "not recommended" battery changes and were able to push pass 72 mph.

The Novak website will have a full write up on our setups and how the day went very soon.

Again, thank you Car Action for the great event. Congrats to all the class winners! See all of you next year!
