Just finished doing a little testing with the Falcon. The results were not bad. The little Falcon started off with a .712 et not a terrible time for a 6 ohm. Then I started tweaking the pickups and the traction magnets. That is when the Falcon started to lay down some nice ETs .593, .571, .567et. The motor was out of the package into the car no break in. I don't think that is to bad. I do think I might be able to drop into the low .5s and possible high .4s. I was using a slip on Jel Claw a sponge silicone tire should be even faster. I may build a couple sets and give that a try.

Sounds good, looking forward to seeing it run at the upcoming race.

I have been working on this chassis design off and on for a while now. I first used the Life Like T-Motor in the very first drag bike designs back in 2007. I like this motor. A big plus is the motors are available here in the states. Of course I needed the chassis to fit my resin cast bodies. So here is a sneak peak at my Carbon Fiber Strap Motor chassis. I have not started testing yet so no ETs . The pictures show the chassis with .550 drag tires. I cast a 40 Ford body for this project, so work needed on it to. I also have plans for wheelie bars for the Carbon Fiber chassis series.

 Here are two of my carbon fiber chassis designs. The pictures show the difference between the two designs. The new design uses a bigger motor. The traction magnets are in front. The chassis is even longer also. The armature is on size with the BSRT, Tyco type armatures. So it should have a lot more torque. When I get a chance I will post ETs of the new chassis. |

Looks good, how well do the traction magnets work mounted like they are?

Here is a picture of the stock T-Motor that fits the new chassis. I have shown this before.
Here is a picture of the unlimited strap motor setup I am working on for this chassis. The motor will feature hotter neo motor mags, fit hotter standard size shaft armatures, and have adjustable brushes.

Here is a pic of both carbon fiber chassis designs. The one in the foreground is the new one. It features the Life Like motor with adjustable traction magnets. Testing has started and a .774et was run. I think I need to change tire height and maybe gears. I would like to hear more rpm's.

Impressive!
Curious and just for reference, do you test these chassis with a body on them?

Impressive! Curious and just for reference, do you test these chassis with a body on them? The first few passes are without a body. Then I add a body for final et's. This one I have not added a body yet. The chassis with the Falcon ran .5s with a body. I am still trying to figure out this setup. The first tires were .550s so I changed to .490 and lost .2 on my et's. So I am printing a new wheel to give me a tire height of around .530s, and see what it does. |

It would be interesting to know what you think about front traction magnets as opposed to rear I have never seen anyone try front magnets

It would be interesting to know what you think about front traction magnets as opposed to rear I have never seen anyone try front magnets kevin Kevin the design came about because I wanted to use larger traction mags than Life Like uses in their chassis. So to keep the rear narrow for tucking under bodies I had to move them forward. As you can probably guess the pickup area can be stuck hard or looser just adjust the magnets. However because of the open design of the Life Like motor (strap motor is what I call it), the rear has quite a lot of down force also. That helps balance the setup out. So you are not completely sticking the front end. I don't get a lot of lifting off the line and almost no blue arch from the pickups. The less you have the better the contact. This setup was really designed for much hotter motors. Those are in the works all based around the strap motor. |
