It's also only 1/8th mile. I haven't started building yet, but I'm going for much more than a stocker. Don't know how successful I will be, but I'm up for the challenge.

I will be working on it. Have not tried anything special yet including weight, just took traction magnets off. One of the real hot ones wont go 2 inches but that is one that can beat 2.5 inline modifieds and runs 40 mph. I think we may be able to get away with a 6-7 ohm but with weak old stock magnets. I doubt anyone will get under 1 second ET but who knows.

1/8TH mile so under 1 sec should be attainable.

No traction magnets in the unlimited class will be tough. Anything other than a stocker I have tried will not go down the track. Dave, Running unlimited Tjets without traction magnets should be a lot like racing your Barretta. It'll be interesting to see how everybody tries to solve the traction problems. Bill |

Yes the Beretta always thought the rear end should take the lead. I have an old VHS video of the car sideways at about 100+ mph where I kept it off the wall. This will be a lot safer racing but it will be interesting. I have some ideas about what to try but we will see.

Wow, tried some more T jets running with no traction magnets. If you like demolition derby this is for you. Even with fairly mild chassis I have had more wrecks in one short test session than in about 6 months of running. Definitely putting some junk bodies on for that one.

Broke the 1/8th in under a second. Tires are going to be the key. Cars are spinning all the way down the track. Some of the runs are pretty spectacular, fishtail city.

1/8 mile in 1/64 scale should be about 10' 4" if I calculated right. Is that what we're looking at running?

The track is tomy with track mate adjustable voltage at 20 amps and bolth lanes fire simultaneously. I will have more to share after i make the post office with my cars for jj's race .put clear on at 6 o'clock last night .ok the hauler just rolled in gotta go |

Starting to get the cars more stable going down the track. Really weird, adding weight to some helped, taking it out helped others??? Cleaning the tires before each run is a must. Tires are crucial. What works on one will not work on another.

In my last race one of the racers won a class by only listening to the sound of the motor when tuning it.

Was able to get one of the Dash 4 ohms down the track. It actually started to fishtail at about the 660 point.

Tried a 1 ohm armature. Actually made it down the track once while flying into the catch box in the air. I think the wheels are going 40 mph, right at the start, and the car is going about 5. Poor thing hit the floor more times than a mop. I put 10 grams of weight on the back of it with 2 armature stuck on poster putty but that was no help at all, tire spin city all the way down until it flies off the track. I sure know that will not work. Got the car with the mean green arm going down the track smoothly now.
