Craig, that chassis looks great!

Is the pan spring wire soldered on none, one or both ends?

[flyracing]

This Retro F-1 took 3rd at the recent Flatrack worlds at Pacific raceway , Only a 3rd but it felt good cause it,s of my own design...

Not soldered at all. I want to be able to remove it easily should it get bent or, if I want to test it without any torsion at all. Even though there wont be much torsion it still offers some stiffening affect..

KAMO KRAIG ahhhh soooo

Good lookin' chassis, Mr. Rieland!

[Dominator]

Nice job on the inner rail there Mr. Reiland.

Could we get a couple of shots of the front with the lead wires out of the way? looks very intresting but I'd love to see shots of the front without the wires.
Thanks,

[Dick]

flyracing,
How about some pics of the bottom. Chassis looks very interesting.

[flyracing]

These shots are the final race car , as I added lead & put some longer pieces of 062 material in the middle . It,s about 120 grams ! keep in mind that's for our totally flat twister track.. gonna go race today !in 90 deg weather !! Gonna need beer fore sure .....

You should know Tom ! since you wrote IT ! OWH (print) magazine #4 page 34 , Notes from the can By S.O. WATT. I think there was a bit of beer drank & Pizza consumed at Bison creek pizza after a Friday night WSSH race when that article was born !

Hi Craig,

Terrific build,

Thanks very much for using some of my stuff on it.

A lot of nice details, but I especially like the curve on the back of the pans and how you "blocked" in
your front wheel supports with round brass rod(?).

A top&bottom shot of the NAGAIKA chassis (Noose named it: Google for a giggle) - this is a development of the "Forward-Flex" concept, stiffening up the center section to just in front of the motor, that tonyp suggested I fool around with; and which Mike Kettleston's been playing with for quite a while too. See, great mimes think alike, they just don't talk much about it.




I'll have some more to say about how this is turning out, but I'll put it over in the Duffy thread where it won't waste space here in the important stuf.

Okay, I'm going to throw my hat in the ring for the BPR chassis wars with my first Can-Am scratch-built.

I took ideas and inspiration from around the country and the Globe, so thanks go to Mr. Hanada for his excellent bracket, and to Tony P., Kamo, Craig C. and Bryan W. for their building tips.




No idea how much it weighs or how it will work. Hopefully I will be able to test and run it at the next SCRRA races on the 25th.

[Craig]

Looks pretty good Bruce, should weigh in around a hundred grams complete by the looks of it. Not certain if I'll be able to make any races for a couple months so keep us informed on how it works.

[The Bugman]

excellent job bruce,,,i bet it'll be great on raceday,,,,,now you just need LAPS
of practice to make it work good for you,,,,,
seeya on raceday

[Mach9]

All of this would be wayyyyy beyond my capabilities. But I just wanted to say that it is beautiful work. LOVE those inline motor chassis. Reminds me of just how much I despise working on angle winder chassis.

[Tex]

Looks GREAT, Bruce!

That is just the kind of weapon that drove me to be a Gen1 American Builder and to hear the famous 'this little piggy' giggle tail story.
. Could it be that those from the EuroZone are now out in front by design with Flex right behind. If that 'thing' whips up near me there is nogay that will live to see another 'horse' race. Got it, mister?
Oh..and BTW, somepeople just are acting out after they make-up without a sound.

Thanks Craig.

Weighed it today at BPR and the naked chassis comes in at an even 61 grams

[Tim Neja]

Looks very nice Bruce!! Should work great!!! Stick it together for next week and we'll chase ya around some!!

[Tom Eatherly]

Bruce, nice build. Looks sturdy enough. Hope it works for you. See you racers on the 25th.
Hey anybody, how did the Flattrack come out?

[usadar]

Hi, Bruce,
Thanks a lot for using a Hanada motor-bracket.
Nob Hanada will be glad to hear when I tell him this weekend.
Good Racing,

This is a chassis for the UKRRA saloon class, call it trans am, a class that doesn't exist in IRRA, 3" max width, wide fronts and 3/4" rears 120g weight limit, all other rules as IRRA. it allows us to race anything from Mini's to NASCAR in the same race, The 3/4 rears allows us to use wheels which have been used on can am or F1, The bodies massively change the handling of a can am chassis knocking at least 0.5seconds of lap times, It is difficult to find a set up that works, so I am constantly trying to get a better handling car that doesn't weigh to much.
I have been making my own brackets for over a year now, the idea is to get the motor as close to the rear axle as possible and for the bracket to be as wide as possible, this gives grip and limits axle tramp. The narrower the bracket even with good bearings the more the wheels can wobble.

Rough bracket soldered to rear plate.


Bracket cleaned up. This is set up with 2 26t gears which is now the largest diameter standard gear that can be used due to the 3/4" min wheel diameter. ratios are changed by changing pinion. I will be machining a few thou of 27 tooth gears to be able to use them also.


This is going to be a Z rail chassis and this is the centre rail 0.64 sleeved at both ends and ground down , solder cannot wick along the rails beyond the tube length.


Basic setup of the chassis with front and rear limits in place.


Axle in place, this is 3/32 piano wire . It does not snap on impact and you can make it to the end of the race. Unlike a drill blank.


The chassis basically finished, the pans are soldered together but float fully in the 4 square tubes which have been slotted to form a channel.


A few views.






The rolling chassis, Evil 9 motor.




Ready to test.

the overall weight is 104.7g for the chassis and 112.1g with body. The weight limit on this class is 120 grams so I will need to add lead and then some brass where the most lead is placed to get the weight low down, if it does not work I'll strip it to the bracket and rebuild afresh, the bracket taking about 4 hours to make.

That thing's pretty groovy.
