Thanks for that information, I will look into those parts. Ordered 10 of those photo cells today from digikey.

Paul from Max Trax called me today and he is going to make a track to fit my space. So far they have been right on the ball with responses. It will have a shorter staging area, full 15' 2" track length and approximately 3' shutdown area He said since I contacted him he has had 4 other calls about a 1/87th HO scale drag strip. Maybe I started something.

Sent in my payment for a Max Trax strip. Price with shipping was 339.40. This included about 1 foot of burnout + 15' 2" of powered strip and approximately 3 feet of shutdown area. Paul custom cut the track to my specs. Delivery was promised within 2 weeks. Excellent communication with the company at this time.

I installed those photo transistors today in my plastic AW track adding a couple of inches to the timed run area making it a full 15' 2" and they work well. If anyone else is doing this the longer lead of the transistor goes to negative, negative is the wire with the stripe on it. Now when the new track arrives I can install these parts and be running in short order.

Gasser/Dave, what scale cars are you planning to run? I have installed SlotDragon on two tracks and they are easy to do following the instructions. if you are planning on mounting the track surface on a platform of sorts, tell Daniel that so he can provide sensors that haven't been bent. for those planning on using the system with plastic snap together track, the bent sensors are what you want. thank you, Top Fuel/jjwallace for the info on replacement sensors. I don't think they are directionally sensitive. rather they are polarity sensitive. all LEDs are. .... oops, I posted after only reading the first page and then found this page .... sorry. still curious what scale cars you are running? 1/87?

I have already installed the system with new photocells. I knew about the polarity, long lead is negative if anybody is installing any. I drilled holes in my boards for all the wires and photo optics so there were no bumps in the track. Daniel told me where to buy the sensors: Digitek. I actually running both 1/87 and 1/64, the cars in the picture, 55 and 57 Chevy are 1/64 I believe. The track is a 1/87th scale 1/4 mile at 15' 2".

Dave, that is very cool and I know you are going to love running a drag strip. where are you getting 1/87 scale cars/bodies? cars about the size of Matchbox and Hot Wheels are generally accepted as 1/64. I think MEV bodies are 1/76. most modern slot bodies from major manufacturers are in the 1/64 range. be sure to cover your sensors when the track is not in use. I already have a Wizzard strip but cost me nearly twice what you paid. if I ever build another I will contact Paul. he is a great guy.

Hey Al, Dave might be guilty of the same thing I always seem to do......... 1/78 - 1/87 I don't know there this big......... never really paid attention to the change in size until recently........ having to get right type of body on given chassis for NTRA races....... ............ Peter
I just call it all H O ..............

The size of the track was dictated by the distance available. I have several older Aurora T Jets which I believe are 1/87 scale. The rest are newer Aurora etc. which are I believe 1/64 scale. I did not know the rules also dictate a certain size car I thought it had to be close but not exact??

Dave, no disrespect intended. just trying to expand my own knowledge and thought you had something I haven't been able to find. Aurora did advertise their vibrators and first of the t-jets as 1/87 (true HO [ half O-gauge ] scale), even going so far as to say that on many of the set boxes at the time. they are not 1/87. if you ever have the opportunity to go to an extensive hobby or train shop, have a look at the platform accessories, especially the cars and trucks that are in scale with the HO (1/87) trains. that will give you the proper perspective on scale. TOMY has made a true 1/87 scale race set and 4 cars that were released in Japan only. some of those sets have made their way to our shores and I had an opportunity to buy one and was too cheap on that occasion. forgive me for taking you to task. I mean no harm, but racing 1/76 or 1/64 scale cars on a 1/87 scale quarter mile makes my mind quiver. just a personal thing. the length you have chosen is very close to a 1/64 scale 1000 foot ( 15' 7.5" ) and if you haven't installed the sensors or decide you want to move them, there is an option for you. feel free to race the length you have chosen. many people that I know just set the sensors at 15 feet and don't quote a scale or scale distance. sorry to be so long winded and sorry if I put you off. just one of my pet peeves. we are good?

Thanks for the info on scales, Al. If I , got it right early Aurora's were 1/76 thought advertised as 1/87......... knew they were not true H O.... had trains for couple of years before cars came out........ they were big. ............. Peter

Never knew Aurora T Jet were not HO scale, only had O gauge trains. The larger size is certainly more manageable for my fingers when handling parts. I have already installed the sensors at 15' 2" mainly because that was about the limit for the room I had and 3' of shutdown is already pretty short. I have looked at some of the other tracks that are running and several are running similar to that length I am running. Some are running to the 1000' mark, 15' 7", and others going about 20' for a 1/64 1/4 mile. I might be able to cut the burnout area down some and add 5.5 inches there to get the 1000' mark if most are going to be using that distance. the sensors are pretty easy to move the way I have them set up. Hardest part is cutting the holes in the support board and getting them in the right spot.

When setting up my track I had the room for 15'-7.5" let over from my old track that was 15'-2" with a longer shutdown. That being said I never get hung up on scales, some guys here hate running a smaller body T Jets with the larger Auto World bodys. I just like seeing different body styles and what guys do to customize them. As far as distance use what fits your space 15-2 is a good distance for a race, in the past I have held 2 proxy races with that distance, and they came out well. We have a track in the club here that is a !/8 mi (I forget the exact length} and we have really fun races there as well. I don't think any one size is better or worse than any other.

I have to agree with you. As long as the distance we are running is known we have a way to judge how well our cars are running compared to others. I have no problem with the size of the cars being slightly different within reason. I am more concerned with performance but some concessions should be made for size.
