Wow!,..I was Just about to say the Same thing !!!
'
You'd think you would need Oval shaped Wheel arches to 'accomodate', that amount of Movement,..Nice work though.

Do you have a similar car to compare the More Forward position of the Motor?,..handling/lap time wise ??

Just wondering what your 'observations' were?

[J&B Bear]

My first mid and another I built are on page 11 in posts 211 and 216 of this thread. This one has the most movement by far. It was kind of a progression from about a 1/16" to a full 1/4". I wanted to see how much is too much. And I found out...lol. Still all work well and you can punch the doughnut on my paperclip. And you`re right it`s abit hard on the body placement. But man the weight transfer upon braking seemed to work well and set the chassis up for the turn great. My track seems to like a floppy car and the king I race at Rt. 93 craves a tighter car so torsions and limited floppy cars work well there. I`m trying to find a happy mid for both and having a GREAT time doing so.
The lap times were comparable on all 3 chassis`s but the sloppy did slow it down about a tenth to a tenth and a half. So I`ll tighten it up and try it again. Ya just don`t know where the edge is till you step over it.

Race on!

This is safe to guess that the duel motor brackets are legal thru the IRRA rules?

After all, it's not a solder together three piece side, it's definite built with a folded 3-sided bracket. Just a couple of them!

May we get an official ruling announcment of this type of build?

Thank You!

[J&B Bear]

Can`t say for sure Brian, hope to get a ruling on the 1st one that does have two motor brackets on page 11 sometime before I took it to a big race. I`m planning on taking it to the R4 in March.
But this one is different than the one you looked at at Rt. 93. This one should conform to the rules as stated. It has a one piece motor bracket I folded up with longer sides to move the motor forward and a rectangle support made of .055 piano wire with a brass insert that contains the sortof carrier bearing in the middle. We`ll see.
Anyway ya go I`ll have to limit the play on the last one but don`t want to play with it at all till I find out the legality of any of the motor forward stuff I`m playing with. No sense in wasting time if it`s not legal. It`s a Prototype thing I`m just playing with.

Race on!

First retropro update... Almost 100% complete! I finished soldering on this thing 20 minutes before the photo, so no good lighting again, or good cleanup. Those will be after testing is done on a king track. After weighing it with almost everything in it, it should hit the track race ready at around 88 grams I finally got one light!!!

[Richie]

And finally finished the D3 Coupe, weighs 97.7 grams as shown... It started as a torsion car, then went to a sled, then after more thought, went to a floppy with limited amount of up/down, fore/aft movement. Bite bar is .047 soldered to main rails... 2nd anglewinder build, retropro above was the first! The next when is on the bench, and it will be awhile before I have it finished, but i'll clean it up purdy for the camera! I just hope this car works on a flat track!!!

This one is heading east. Basic build and should come in at 115 grams RTR, leaving some room for left side weight. Trying out the shaker pins? and some other changes for this one.

[Tex]

I like the gude centering method. I've contemplated something like that but never did it. Well done.

[Rick]

Special Edition Samurai II for Chris out in the East. He has to race almost all high speed tracks. 100 gram RTR.

[gascarnut]

Just finished this one for all-time good guy, Mike Kravitz:





Perhaps the last frame to be built with the kits that Chris had at BPR?

Wheelbase is 3 7/8", guide lead is 7/8" and the frame weighs 50 grams as pictured.

Parma fronts opened up to run on a .078" axle, and with bigger O-rings ground to an actual 5/8", not the undesize 5/8" that Parma put on the packet...........

Enjoy, Mike!

Wow Dennis, that's really beautiful workmanship. It REALLY is. I like the lead wire loop-d-loop gizmo too. Very clever and sano.

Rick

[Old pink can guy]

Dennis very sweet. I have to ask is my computer or my eyes messed up. the photo of the bottom of the chassis looks like the center plate is up side down? Have I lost it do I need help?

[gascarnut]

Thanks Rick, coming from you that is enormous praise!

Ken, it's an optical illusion, but I see what you mean. Trust me, I spent so much time getting the angle of that guide tongue right, I KNOW it is the right way up!

[Windyracer]

Hey Dennis,

Beautiful work as allways. Missed you at the Sano III this year. Hope to see you at the R-4 3, or next years Sano.

Cheers, Ken

[Richie]

Dennis,

Beautiful car, goodluck at the Checkpoint Cup! I have acquired 6 new M&M nosepieces, can't wait to build my own retropro now!!!

Well.... ... Not quite....













( Maybe if I post this w/ Dennis' photo, it'll make my struff look as good! )

I'm fortunate to know many of the "great builders" here in SoCal, ( although I find it difficult to included myself, truthfully... ), & often we trade parts & do "G"-jobs for each other, depending on if we have access to the required machinery... So, when Paul Sterret asked for a quick job to facilitate tech-inspection at "the Checkpoint", I agreed... Needless to say, when he thanked me & then handed me this Racer .050 nosepiece, that Chris had at the counter a few months back, I was ecstatic... So, wanting to relax prior to Friday night's RetroPro race ( 3 hrs. to chenge-out a stupid Big Dog arm ... Murphy was with me, every step! ...) I took a pr. of my Slot Tech Services .025" side pans from back in... er ... '86, & built this sucker in 4 hrs. ... ... Every rail, except the piece that re-inforces the rear axle tube, which is .062, is .055, as per the suggestion of Mr. Bob Crane... It includes the floating bite-bar concept, as shown me by Craig Correia ... This should work well as a flat-track car, & still be light enough to run on the King... 3.890 wheelbase, w/ a .655 guide lead....

I know Mr. Kravitz will enjoy that chassis, Dennis.... Your typical excellent workmanship, second to none... Always enjoy looking at your builds...

Thanks, guys... Oh, boy! ... ... "The Checkpoint" is ALMOST here! ... Good luck to ALL our racers !!!

Good jobs, both Dennis and Jeff!

Ok this was a chassis that I just could get to work so I left the motor box and guide tong with the main rails and striped the rest. I want to try and make a chassis for the king track for a IRRA race at Slots this weekend.
This is an attempt at making a Tony P type Aero chassis but not a exact copy . I think It came out pretty good and the action seems nice and it took quite a while to do . It weighs in at 69 grams as pictured with the bearings and the WB is 3.75 with a .997 GL and that is 4.77 from rear axle to the flag. Sorry but no tumbler so this is how it looks all comments welcome.

[Tex]

I'm wondering if I'm seeing correctly, Joe. Is only the two very oustside pieces of brass actually hinged, and the two "inside" pans are soldered solid?

Sorry for the poor photo quality.
No the inside and outside are hinged. On the inside pans it is hinged up in the front and in the mid to rear of the chassis.
The outers are hinged at the far rear and the U hinge at the front of the outer pans.

Rich , maybe this will help sorry for the glare put your sun glasses on.

[Mark C.]

cool looking chassis mig, cant wait to see it on the track saturday. I heard some Retro East boys will be joining us as well

[Richie]

New Build.... figured might as well post pics, has been a lot of activity in the gallery lately

[JerseyJohn]

Is that GT coupe on the KIng ?????????????? Hummmm What Time?

[Noose]

Beware the "Aero Pod"!!

This is the latest from the 3 Dimensional mind of Tony P. A Tri Pod Aero chassis. Total weight of the car with body comes in at 105 grams.
