We broke the track record!! 229.34mph 2.9730 seconds

[McDoodle]

This is the car we raced this year at the districts. With all the tips we learned from you guys we built an amazing car. Im fairly new to PWD so trust me when I say if I can do it so can you. Thank you

Sweet, That's what I am shooting for is to set a track record somewhere. Do the wheel weights I see in the rear have any advantage? I see that is the new thing.

 

[McDoodle]

I believe they made a difference yes. It gives the car an aggressive stance. It came off quick from the pin and pulled away fast once it got off the bend. I'm trying to upload the videos. I used bent axles in our pack race but for this race I used the drill press to drill the cant for the axles. I think that helped us immensely. You don't have to worry about trying to tune each wheel because they're all drilled the same. The only tuning we used was the steer wheel with the axle bent at approximately 2 degrees. If all your wheels have to touch the track try to make your front wheel that isn't steering just barely touch the track. And ask a lot of questions here. This forum is loaded with info. With the side weights I could still squeeze 6-1/4" tungsten cubes underneath the car too. Just fyi.

BTW, the car looks fantastic...

Thanks B_Regal Racing. The car actually came off the track twice because they didn't set it up right so there's some battle wounds lol. Idk if I could ever build a car faster than this but we're gonna try/images/boards/smilies/wink.gif Me and my son love this hobby. We're talking about making a car for the NPWDRL next year.

 

[BulldogRacing]

Nice job applying the tips and tricks, congrats!

 

[OPARENNEN]

Last Saturday my grandson took FTD in an AZ Council race with a time faster than the league SS class, even though our car's body was a DD4H plug-and-play. So using a smart phone angle measure ap, I checked the in-run. You guessed it, the angle was a few degrees steeper. So as indicated in another post, every track differs to some degree.

Nice job and nice aesthetics -

You should send it in to NPWDRL - Box stock (assuming you ran BSA axles and the only wheel 'modification' was bore prep) - I think you would also be in the running for best looking car as well.......

Thank you zigzag. This car is going on my sons trophy shelf but I want to build one for the NPWDRL. Do they race every month?

Yep - there are races virtually every month. See NPWDRL for race schedule and rules per class.

Very cool looking car. Great job!

 

[McDoodle]

Thanks Davet. Cant wait to build the next one.

 

[GravityX]

Great job McDoodle!

 

[gdurban]

Very nice. what fenders did you use?

 

[davet]

I just looked closer at the pics and see that you were smokin' em' pretty well with that time. Cool.

 

[Kinser Racing]

Congratulations!

The first time I saw the software post a time of 200+ MPH, I actually thought to myself, "Really, wow, that's fast, it don't look that fast, is it rally 200 MPH." I was never going to share that but it truly went through my thick skull.

 

[McDoodle]

Sorry for the late response but I made my own fenders out of 3-1/8" pieces of balsa glued together. They're an exact copy of max velocity was selling.

I thought the same thing lol. Maybe it's a scale speed

 

[gdurban]

It is a scaled speed. You take track length and divide by your time, which gives you feet/sec. Then divide by 5280 to convert feet to miles. Then multiply by 3600 to convert seconds to hours. Finally, there is a car scale factor in the race software. It defaults to something like 25 to 1.

So, on a 42 ft track and a 3 second finish time and 25:1 scale, you get 238.63 mph.

For your race, the actual race distance could be less than 42 ft because start and finish are set in from ends.

Assuming 2 feet shorter: (40 ft/2.973 sec)*(3600/5280)*25 = 229.336 mph....BINGO!
