I will do some experiments with my inlines and let you know tomorrow. I can set my power supply
to 1.5 and disconnect the second power supply. Should be interesting.
What are your spending limits since some of mine are $100 cars. I doubt
they would run on 1.5 amp since they pulled near about 8.5- 9amps on my track.

Like to stay under $200 which shouldn't be much of a problem. I have no way to check speed on her cars now we don't even have a track yet that's why I'm so pressed to get one going. I am gonna order a few more parts for a couple of her cars and get them put back together for spares. How much would you charge to run a couple of hers and check speed for me and give me a few suggestions on them also.

Just send 7.00 for return shipping just like we do for a proxy race and I can check the cars for you.
I can give you speed, ET, even 60' and 660' times. Some cars run better on short tracks than others so the different increments show where the cars are picking up or falling down.
Let me know and I can send you my address.
I can also make some suggestions if I see a problem with something.

Peter
It is on a plastic tomy afx track 20 ft no timing I don't think I think it just uses a win light

Peter It is on a plastic tomy afx track 20 ft no timing I don't think I think it just uses a win light Ok, so on the plastic track what kind of tire/wheel set up & how big is OD on tires front & back (back is more important). Forget what it was you said about traction mags , did catch my attention at time. ....... Peter |

Are the lanes fed separately?

Dave it is its 20v 1.5 amp per lane.
Peter that's a good question lol. I bought the axles from terry Flynn at hc slots. I got them already pressed since I don't have a wheel press yet. They ate jel claw tires but not sure outer diameter I can give you a bottom to top measurement in standard I broke my caliber so I have to buy another one of them. The front is pro trax o ring front end from hc slots also if you pm me your cell number I will send you some pics I cant figure out how to add them on here from my phone. Or if you have a facebook I can send them that way

Or if you have a facebook I can send them that way Look down home page..... near bottem is how to post pics. If you are using braids on pick up shoes. Front tires may be lifted from track. Shoes botteming out in front window of shoe is indication. A thicker o-ring could help cure. On a continuous rail track this might not make a difference. On a plastic sectional track transfer of energy is up if rails are off between sections. Can cause desloting if hitting high rail when car is bottemed. From tire description you may be using dbl flange wheels. While you might find a tire that works. IMO, you will get better performance from a silicon coated foam tire or sili-foam. They will also be true out of the package. I run .454 tires with 8/22 gears in both my mm/ps cars. One of which is built with t-bulkhead as you described. The difference is in mtr mags mm/pc are ceramic grade. For polys I would try a 21t crown to begin with. I think neo mags would be to strong. ......... Peter |

Peter I don't have photo bucket on my phone. I'm not good with computers so I use my cell lol. The rear are slip on single flange this car she has now runs double pick up springs on silver shoes. I was wondering has anyone ever tried the level 19 wizzard motor magnets she has viper pro 4 now. Also on the wheels they came on the wizzard pro axle with white gear. Where is the best place to buy the bsrt chassis and parts. Would buying straight from Gary at scale auto be best. Also I found a bsrt spinner arm for Tyco its 36.5g do y'all know what this should ohm at.

Here is some info on what I found on my track.
I set a single power supply down to 3 amps as mine are
hooked together in parallel.
With 20 amps going there is little effect when 2 cars are
running, with 3 amps there are some drastic effects. The high
draw cars will absolutely kill the lower draw cars if they are run
off the same power supply. At 1.5 amps the hotter cars just shut the
power supply off.
Since the lanes you will be running on are separate you do not have to worry about
one car effecting the other.
6 and 9 ohm cars ran pretty close to normal running about 2-3 hundredths
off pace and losing hardly any mph as the current draw drops as the car moves
down the track.
The 3 ohm cars as expected were effected more by the current loss. Losing
about 4-5 hundredths and 1 mph.
Tried one of the hot cars and it was devastated by the current losing more than 2 tenths
of a second and 14 mph off normal times. 2 tenths of a second is about 1/2
the track with these cars. It was also a tenth off the 3 ohm cars times.
This tells you a 3 ohm armature is what you want for your race.
I ran more than one 3 ohm arm and there is a pretty big difference in those.
The BSRT G3 #906 is the one I would recommend if you want to win that race.
It is a complete chassis, all you need to do is mount a body. It will run .4s in the
high 20s right out of the box and I will be very surprised if anyone comes
near that car. It is expensive at 85.00 for the running chassis. Buy the Tomy #8838
body clip from them to go with it and you can mount an AFX body easily.
If that is to much there are other armatures that you can mount into your
own inline. I bought some from 12.00- 20.00 that ran OK, Add some good magnets, level 10s are good,
and it will run pretty good, just not as good as the BSRT.
Be advised that there are some armatures that are 90 degrees
out of phase from others. In other words the brushes are either in line with the
magnets or 90 degrees opposite them so check before you buy.

I don't have a spinner 36.5 but a 34 reads in the low 1s which indicates that a 36.5 would be in the higher ones, not good for what you are doing. Never tried level 19s either. They would work well with that 36.5 but I think they would be to much for a 3 ohm.

Thanks for the info Dave. I guess that's what I will be going with then. You guys sure know alot more about these than I do. Would you buy the bsrt and run just like it comes or would you use a decosmo bulk head and add high performance parts to the car like the adjustable brush barrels and all silver electronics. Also if you did that would shunt wires help or am I over killing with all that for the amperage. Also on this car what gears would you use for 20ft of track. I think I stinks I wish they would bump up the amps and voltage I would like to see if I could build a real car lol. That's why I'm gonna fix a track here at home I hate to buy all those parts and fix a car and not see how it runs. I run them on a 9volt battery and do it by ear as of this second. Dave I noticed you live in Tennessee I'm in ky off of I 65 exit 65 in munfordville KY.

They would work well with that 36.5 but I think they would be to much for a 3 ohm. VOM .......... to know for sure. Green wire arms ohm around 2.7 , think they are 36g. Number of winds will make difference. Also wire guage varies from one mfg to another. Guages indicate a given range of standard measurement. Not a specific number. 36g does not sound ffamiliar as a "spinner". Unless perhaps it is dbl wound. In which case lvl.19's would be called for. But this may well be to much for 1.5a. I just recently put lvl 19 mags in chassis w/grn wire. Run on 13v walwart is faster than lower level polys. I'm sure 0.5 amps is hurting performance. But it is still hands down faster than lvl 10's. Consider that finding a combination of arm & mag that will yield the fastest time under parameters. May be inconsistent at best. If your pushing the limit for available amps. What blisters track once may not move the next time. Or it might go two rounds before the quirky sets in again. Being this is your daughters (whats her name) race. I would imagine consistency is a concern. For that reason a 3 ohm or 2.7 gw is as far as I would go as for arm. Based on my first results with lvl 19 mags. I would not be scared to go there. In fact I would go with 19's. Lewis , thought of this before don't want to forget. If it's ok with you your daughter can post things here. She just can't register because of age. Posting would have to be under your log-in. This has happened in past. Does your girl race under her name or use an alias like us big kids do........ dui. She can be anyone she wants here. Just be best to have her announce who she is. If you & she care to. It will keep responses in line. .......... Peter |

Peter thanks for info.
I think I'm gonna get the bsrt 906 poly car and try it I have been reading on it since Dave recommended it. As for the Tyco cars she has now a couple have the green wires and pro 4 poly mags but I like tinkering with the Tyco cars so I'm gonna order some of the level 19 mags and some more electrical parts and see what I can do with them when I get me a track.
