I have been collecting data/pics/videos on all the high speed runs. I wanted to have a nice one stop place to see everything from every run. The website is here. I am still working on getting video of Cliff Letts 111mph run and info on Chris Collins drag run. If anyone has more info on these projects or runs I am missing, let me know. I'd like to keep everything on this site for future runs also.
Did you make the airfoil for your wind tunnel testing?
Check with Mike Ogle of Grand Motorsports. He's the guru on all the old speed runs and helped Chris Collins so he may have some additional info. I know at least one of the guys over at HPI USA was really into it as well. You might want to track him down.

Yes, I made the 2 airfoil sections for my testing. They are cut from foam and covered in fiberglass. They were really easy to make. Then I just glued some thin aluminum to the ends. I have a lot more info to post, so the few pics are a start. I have graphs showing the drag and downforce from the different wings I used. I have a whole research paper that I should link to.
I was standing at the end of the track when Chris made his 112 MPH pass and it was very impressive indeed. We were at a IEDA Summer Nationals event hosted by Kent Valshing in Minnesota and I had just made a 101.2 MPH pass with my TF Electric dragster. At that time, it was only the second 100 MPH+ ever recorded & I was a very happy fellow. Needless to say, my time in the "limelight" was short lived! Unfortunately I suffered radio problems & was unable to make another pass.
Chris' pass was made in 300' from a standing start & the first half of the track had been sprayed with sugar water for the IEDA race. This helped acceleration quite a bit & by the time the evening was over 4 or 5 other racers had exceeded 100 MPH also. The track was located in a school parking lot and wasn't real smooth so all these runs were impressive to me.
Now those 134 & 160 MPH runs Nic made at Fontana Raceway........those were REAL impressive, no matter where you were standing.
I would sure enjoy it if MR Ogle could make the next LSR event.....his vast experience would be a true asset in this type of racing. Maybe we can talk him into attending!

Hi Craps, hope to see you there too.
Jim Schauer
Wow that is impressive. Jim, do you have pics or videos from those runs? I have no information at all about those drag runs and would really like more info to put on my site. The information you gave me is great, its a start.
Hi B4.....no video was taken as far as I know. Back then video cameras were huge & uncommon. Additionally, it was 9:00 at night and nearly dark when Chris ran & that may have prevented descent photography. I may have pics of the IEDA race & I'll check soon.
That airfoil looks very nice. You did a good job!.
I forgot to mention earlier, their was an article put out by one of the other mags. I believe it was Extreme RC Cars back in 2002-2003. They did a full two page spread with detailed photos of Collin's dragster. It was that article that sparked my decision to build a speed car.
Jim,
I knew there was a second guy that ran over 100 but I couldn't remember your name. It's a shame because that was a real feat back in those days for any RC car. Most people back then, 70 mph blew their minds and there are cars today that do that out of the box!
That unknown speed car on your website may belong to the owner of www.rcindycars.com you might want to check with him for additional info. It looks like something he would have built.

Those scale indy cars are cool. I wonder how well they would hold up in a speed run.
I've already been down that road. The problem with indy cars that small is the amount of drag the open wheels create. Think of it like this, if the car is moving forward that means the tires are rotating forward as well. As it picks up speed the force of the air moving over the tires will be in the opposite direction. These two opposing forces will create alot of drag. There is however a way around this, simply cover the wheels. Check out the pick below for an example. See how the rear wheels are covered. You would have to do the same to the front as well.
hi guys.
i might as well introduce myself. my name is georg esterer. i used to race all different types of rc cars in the late eighties and early nineties.
i got an email from an old friend and fellow racer the other day. you probably all know him; mike ogle. anyways, he told me about this site and sent me a link to this particular thread.
i had the first car to go over 100mph back in 94. the car still exists and is on display at J & M Hobby House in san carlos CA. i worked there for a few years during high schoold and college. it was the only way i could afford to race.
i can post some more info about the car if you guys are interested. i still have a copy of one of the old rc car mags that the car was featured in and coud scan some of the pages as well.
i don't race rc cars anymore but it's good to see that people are still into the speed runs and other aspects of racing. i always had a good time doing this stuff.

That would be really cool if you can post any info George
Hi George......I was there when you ran 105 (or 106)mph in Sunnyvale. Very impressive, and also the only 100+ run for quite a long time. Wasn't that a Bob Boucher special on about 20 nicads? Those were fun races with Mitch & the gang. Wondered if you still raced. Come to Fontana this summer & give these guys a go!
The batteries are so good now a racer in Florida ran 1.52 at 80+ in 132'.......on 10 cells (4200's)......in a funny car. Not sure, but I believe this may have been an IMDRA event. This year they'll allow LiPo batteries in the Extreme class too. Should be fun.
hey guys.
thanks for the props. yeah, those were fun times. the only cars i have currently are my old but built-to-the-hilt RC10GT for the sand dunes and a bone stock MGT with the big engine. i bring them with me when we go four wheeling and rock crawling. since the rc days i've graduated to that hobby and it's turned into my livelihood in the last year; just opened my own shop doing mostly conversions and fabrication on full size toys.
anyways, i dug up the old mag with the article in it. at the time of that speed run there really was'nt much info out there and the internet was a futuristic dream so i just gave it an educated guess more or less. i sat down with a calculator and tried to figure out how much the tires would expand when exposed to enough rpms to achieve 100mph plus. then i got a hold of bob and discussed the best electric motor choice, found a good chassis and called my batter supplier at the time and hit them up for some of the best cells i could get my hands on. back then, they were 900MAH red cell nicads!
i guess it all worked out in the end although the first run was'nt very successful. about half way down the track the car started smoking and making awful noises. i though i'd blown up the motor (running 24 cells since bob told me it should hold up to that during short runs). turns out i did'nt trim the rear fenders enough and the tires hit the body, creating the smoke and shaving the tires down in the center.
i put a new pair of tires on the tire machine, trued them up, trimmed the body, topped of the batteries on my tekin (RIp) charger and ran the second attempt. that one netted the 105 mph run. i did'nt wanna push my luck so i pretty much bagged the car at that point. my team mate, doug peterson, ran my backup car and got 96mph with it. that got him 2nd place. pretty good day for us since we raced in the regular drags as well and did good there also.
my 5 minutes of fame!
That's cool. Everyone has their 15 minutes in the sun. Also, everyone goes from one hobby to another. I was into BMX freestyle as a kid and car audio SPL a number of years back (had my mug in two feature articles myself). But, RC seems to always call me back.
Thanks for posting the magazine articles.......I have that issue somewhere in the archives. I dont see me in the pictures, but Mike Ogle & Larry Lockmann doen't show either......don't know how we missed out.
I won the 10 cell TA/D class that race & I think it was Rick Yoder that was in the final round with me. As far as the LSR goes, I made one pass in the mid 80's and exploded the commutator in my motor. That resulted in no brakes & my car ended up hitting a curb about a block past the timing lights! That pretty much ended my efforts for the day. I had already headed back to So. Cal. by the time the event ended.
I did race another LSR held by the guys at B.A.D R/C in 1997 just north of San Jose. I managed to win that one at 98+ mph, but the track was very rough and Mike Ogle, Steve Saik and Cliff Lett all suffered car problems as a result. That one was run for 300' from a standing start too. Wish they had continued the tradition, but everyone seemed to lose interest......too bad!
