After morphing a P-3 to a pretty stable top fuel platform, decided to continue with a previous project, morphing a Lifelike chassis (you know the one that is fast but basically comes with a disposable or non rebuild-able motor) to well, suit my wants. I've noticed that these motors seem to have very strong magnets might even be neo's but most neo motor magnets like the p-3 or 440x2 are imo hard to work with whereas these lifelike motors have the motor magnets attached to the motor frame and therefore easier to work with. So far I have drilled or reamed out the bearing to accommodate your typical tyco 440/p-3 armature, installed shortened brush tubes from a p-3. Now I can run any type of arm. Just need to figure out a way to attach the TF rail to the chassis... Attachments:

All dressed up and nowhere to go... track still down. This should give me time to work on the painting or vinyl stickers or something for the bodies. Besides I have been instructed by Cinc-House that the track will have to be put away until the holidays are over... reckon I'll see you all next year and either the new circuit board for the timing system will be here or the broken one repaired. Happy Holidays  Attachments:

Think i have finally come up with the motor/main chassis for all the nitro class. The very modified Life-Like motor with what I call "Belly" pick-ups. Now to work on extending the rear end so I can snuggle up some meats by at least 1/8" on both sides toward the chassis. Attachments:

After getting the timing system repaired, I ran a few time runs and here are some results, mind you at over 50 my reaction times are not what they used to be ;D all vehicles including the modified motors ran 6ohm arms, stock traction mags, rear ends and same size tire diameters, ran 3 times down the 1/8 mile track Stock T-chassis-ave .61 sec stock 440-x2 (narrow)- ave .63 sec TF T-chassis with modified motor,and wheelie bar pu's ave- .52 sec same as above with "belly" pu's -ave .52 sec TF with modified P-3 chassis and wheelie bar pu's- ave .48 sec same as the above with belly pu's- ave .53 sec So it seems to indicate at least initially the the "wheelie bar pu's do in fact work better at least on the p-3 frame. Now to try the FC's and I'll have to purchase a few more Stock P-3 chassis (cut em all up  ) just so I can get a baseline on them. |

After further review it seems the belly pu's do work but cause to much wheel spin. I was running them with just one trac mag so went to two but this time it would blow the slip on tires off the rims, couldn't get a single run out of 5 tries... eh, more work needed. here's a pic of my looooow budget track Attachments:

Great ideas here! A question, would this pick up configuration be legal to use on the T/F class of 4 gear, in the upcoming NTRA Summer Nats?

I do love the work.

Having no knowledge of NTRA rules, probably not. Besides I've never worked on a 4-gear platform but if it's anything like a normal pancake chassis, might be kind of hard to install either style of pu. By the way can anyone tell me what kind of ET's those AW TF's do?

This weekend is the Test & Tune for the Summer NAts. They will be posting best times for T/F along with the other classes. That should give you a good idea of times.
Race on.

Hey JW,
Was looking through old thread and caught part about brush tubes in LL can. Have thought about doing this but keep shying away. Got to give it a try. Maybe rewind LL arm first before drilling bushings out and give it a shot. Hmmmmm......

Pceng, if you decide to go the LL rewind way you don't have to use cut down brush barrels, I did just to keep the chassis as narrow as possible. And if you like those LL arms let me know I have about 10 or so of these arms (used but still good) that I would be more than happy to trade for some ring and pinions (another draw back of high voltage racing). Just wanted to add that the reason I like the high voltage drag racing is they replicate the real boys like going up in smoke (arm wise), getting out the groove, yes some will bounce all over the track, and you must rebuild the motor (change brushes/spring) after every round. And I bet one could get the tires to go up in smoke if the vehicles weighed the same scale wise like top fuel NHRA 1800 lbs would be 4 lbs HO scale. JW

Thought to rewind was changing wind pattern for east/west vs. north south brushes. The tiny brushes in stock bulkhead get ate up fast. Real real fast with 0.6 ohm rewind (30g). So idea of being able to change/replace brushes is the only way to go if this arm is ever going to be usable. Wonder if I could wet-com it with the tubes ? Oh I'm definatly doing this.
Have you checked the difference in strength between the LL mags and the ones used for the other arm you tested (p3 was it) ? If the LL are neo, the mags might be to much for a smaller 6.0 ohm arm. 3.0 ohmer might be better with the LL mags. Just thinking.........
