Spent the day building a Kamo Square clone for the race on Labor day.  I'm hoping this chassis works well but I have some reservations.  

 

This particular design doesn't allow much movement in the pans but what the heck.  Gotta try it.

By the way, the second shot was pre-washed.  Looks much better after a scrubbing.

I cannot take much credit for the nose piece Paul, I had Bryan Warmack make up the rough dims and I modified it as required. 

 

As for the motor bracket, I use the Hanada bracket that comes from Japan.  They are the straightest available that I have found so far.

Haruki ran a chassis like that,and qualified 4.20,,Tim Neja ,using one of Haruki's Kamo-Spiders,and out qual'd him,4.19 !,,,,,

so maybe you've cloned the wrong chassis,,,,,lol

Oscar,

The Square I raced at SWC was a little more forgiving than the Spider Tim raced.

I tried the Square, the Spider & my old Speed which Bob Crane & Jay Henry raced at the Cneckpoint & the Zimmerman respectively at BPR.

All the three ran very well but I raced the Square because I wanted to try it at the real racing condition.

Oscar, the Kamo-Spider may have gone faster but you must take into consideration the complexity of the Spider chassis.  The square is a much simpler chassis to create and even though I have a great deal of patience I can't fathom what it would take to recreate the spider's lines.  Yeah, I know that Terry has all those great looking chopped up chassis all cut with a dremel and filed to precision but he must have the patience of a saint to make his cars.  I don't have or want to spend that much time making them that creative.  Now, on the other side of the coin, I'd build a spider if I had the parts. 

 

My plans are to have five to six new cars for the 2014 Checkpoint cup.  That way I can pick and choose the best from my stable.

Nothing wrong with basics

 

I've built and tested well over a dozen variations of "tuning fork" frames in the last few months and have discovered that while they can be very good in some situations,......the emphasis should be on some. No one fork chassis (to date) has been good everywhere.

 

So, when I was asked by one of our raceways for some customer cars, I chose not to go with the forkers but to do some more basic designs that require less tuning. These two new and one refurbished frame are all dependable and successful on any track. These three are all built basically from scratch with little other than the motor bracket as a pre-manufactured part. All cars are 4" X 1"

 

L: 3 X 055, all brass plate 1/16", R Geo 1" pro bracket.

  • Pretty light and bitey design, usually works well with treated tires and medium downforce
  • This frame is great on high speed tracks and doable on flat tracks (usually with some weight)
  • Compared to the single rail, this frame is usually a little faster if you tune it right.

C: 2 X 055, brass is all 1/16", bracket is JK.

  • Of non fork F-1's this has become my standard.
  • With the center weight in place = 102 gr finished car. Good on flat tracks as is or with added weight.
  • Center weight dropped out = 94 gr. Very good on banked tracks but too light for a flat track

R: 1 X .078. Pans and rear tabs are .032 brass, front plates are 1/16". Warmack bracket and tongue.

  • This has been my standard Can Am. Not always fastest but it's always in the box and always works.
  • This frame is not picky about tire choice or body style and works well on Flat or high speed tracks.

Russ, that F1 is gorgeous! Please let us know how it works.

Well, the new chassis got in it's first race & the results are very encouraging. I miss the podium by two laps, but that's because of driver stupidity & a little undergearing. The car was also a bit light, about 98.7 grams. Other than that, the chassis handled superb; no chatter, no oversteer, no weird stuff. Of course, this was on a Blue King; the real test will be a road course, which is where we normally drive these cars. Next stop, SCR on Sept 15th, see you then.  :i-m_so_happy:

Great chassis Rick!  It's my favorite right now.  Mine is a little closer to a "manta Ray"

Hello again all,

 

You may remember the nose piece I cut up a couple weeks ago shown below.

 

Duran clone nose pc 1.jpg

 

I had planned to build it like this.

 

Duran-Model.jpg

 

However, I had to make some changes on the fly and this is what I came up with.

All of the dimensions are as designed with the exception of the pan design, motor bracket and up-stops.

Hello everyone,,,Iv got DCR #18 about done,,it just needs some TLC to make it pretty & clean.Do to some health issues Iv been building very little lately.Its a KAMO style clone,,with a few tweaks and mods I like for the BPR tracks.

 

Im always looking that that "Perfect" chassis so I try to make every chassis a bit different then the last,,it seems as soon as Im done with a chassis I think of a better idea{and sometimes they work,and sometimes they don't..LOL}.

 

This chassis weighs 45g as it sits,,,so that should build a 92-93g race car,and Iv had very good luck with cars in that range.Im starting to build some more "Odd" loose track cars right now just to have on those slimy track days.

 

Take Care and have a good week to everyone......................DC

Chassis looks amazing ! Not always about quantity, but rather quality and this creation oozes it :D

Really simple but I can imagine really technical! Hope the health issues clear up :)

will be studying it closely , plenty of info for when i start scratch building ,after my first kit which is sitting on the jig as I type.

No attachment, they simply slip in the tube to allow them to rotate freely.  The two smaller pieces of tubing are installed for adjusting the amount of flex should the car produce to much bite.

Thanks Tex.  The advantage the multi-rail is less wire bending and with more rails soldered together it eliminated the rear steer while still providing from twisty flex.  The danger to the multi-rail is too much heat will warp the rails causing tension.
