Quick report from the 2009 ROSSA speed challenge


Written by Tony Lovering:

Hi Guys

Just back from the event so here is a quick review just to keep people updated. More reports, vids and pics will follow.

The weather on Saturday was perfect with bright sunny weather and we were off to flying start right away. Kevin Simms blasted the UK record set by Vassmar last year at 104mph with a run of 111mph with his Losi XXXs.

I was concentrating on the rocket car and manages a decent run with 1/2 NOS at 58mph. The car went straight so we were all set for a flying run. Next run saw a craking 117mph much to Kevins dismay.

Kevin also was putting in flying times with his B4 buggy of 94-97mph.

Jay was putting in some really ast times with his 2 cell stock car and was pushing the record right up to 87mph.

The final run with the rocket car on the Saturday was clocked at 107mph.

Ken turned up and concentrated in getting his jet car preapared for the sunday.

Sunday came and it was dry but a bit windy. The times were a bit lower but lots of good times were posted in the 80s and 90s. Keving plugged away all day with his B4 and manged to finall break the 100mph barrier. Jony Bast from Sweden plugged away with his 4cell 2wd F1 car and got 94mph. Andy managed a decent 51mph with hos revo. Tom pennington couldnt better the 75mph he got with his xray 2 cell on the first day. Jay and Time were setting decent times and Allan Waterfall and John Veal were having their usuall too and fro on their IC bikes. John managed to come out on top this year with 85mph.

Then there was the final run with the rocket...

The previous runs were pretty good and I knew the car had potential for more speed. As this was the last run I opened the NOS injector up from 1.5mm to 2mm and the exit nozzle from 8.5mm to 9.5mm. I filled the accumulator with over 16oz of NOZ and pressureed it up to 1100 psi and set it up about 200m firther back than the previous run.

Tom hit the ignitor and I waited a good 5 seconds for the heat to build before I pulled the throttle and off she went. The rocket started slow and at about 1/3rd of the way into the run really took off. The car went through the speed trap and started to vear so I tried a correction but it went over and skidded about 100m on its room.

The guys ran over to the speed trap and read the numbers...

163.58mph and a new worlds record beating the existing record set by Nic Case of 161.76mph last year.

I'm waiting for the videos but hope to post something really soon

Thanks to everybody who turned up and made the event what it was. I'm sure all of you pus many more will be back again next year.

Also thanks to Jerremy at the drag strip who supports our events and does a fantastic job of preparing reviews for mags and other promo stuff.

Special thanks to Tom for his help again and also for the techincal input of Carolyn Chambers without hwhos help I could not have built the rocket car

A full report will be out soon

Cheers

Video: 100 mph brushless Team Associated RC8




Mike used a Castle Creations 2650kv on 6S a 25T pinion, custom fitted 34t spur gear, ofna foam tires and adjusted the suspension to reach these insane speeds.Mike had a couple comments about the run:
We had no need for the gyro, it go pretty straight the way we setup it.

The wing really have a role to play, run a buggy without wing and i guarantee you will lose control over 50mph, it will spin out. :)

We did changed the wing though, the stock RC8 wing had too much downforce and the buggy was lifting slowly the front end, we had no steering over 75mph lol and sometimes it was lifting slowly, that buggy is very controllable!

Its an ofna hi downforce wing that we have cut a part of the downforce...
just to have the right amount of downforce at 100mph.

We set the rear with a slight toe-in, barely, cant say the degree...i have no idea lol

we try to have the best contact with the road with the camber.
And the most important is to adjust them so its the same left and right, everything need to be very precise... if the car slightly pull left or right it will slow it down.

Video: Mike Peperni's 78mph SC8E

This is what Mike said about the run:

We wanted to see what kind of top speed we could get out of the SC8!
the setup had plenty of power to move the truck, but the way the truck is made it is very light over 70mph, sometimes it was getting airborn! We used a Neu 1515 1.5d, MMM esc, on 6S (2X 3S) ThunderPower 40C 5000mah and ofna rubber tires, didnt had the foam tires available at that time...

New contender in drag racing

There is a new premium drag racing chassis to race against now. Urban Assault Racing has engineered a unique direct drive drag racing chassis. It utilizes a "Torque Tube" design to minimize distortion due to the high torque of today's brushless motors. Could this be the fastest 2wd R/C car available? First production "prototype" will be completed in the next few days with final production to start soon after. Check out Urban Assault Racing for more details.
