Sprite Proxy Race 2018 - VTECFOUR's build

Postby VTECFOUR » Thu Jul 27, 2017 3:51 pm

Still waiting for a small item to be included in the kits for distribution so in the meantime, I've been contemplating the modeling aspect of my entry.

Didn't have to look far.

Image

Always liked my Sprite Proxy 2013 stock class entry in 1:32, so I'm going to model a larger version.

Oh man, I was thinking about a French blue color scheme! Is that part of the bigger plan, too?

Just finished casting the last set of headlights. Kits will be shipped after this long weekend beginning August 8th.

Let the building begin!

Mounted a head rest fairing that I had resin cast for another car.

Image

Mock fit it on my prototype chassis with a driver head and Brooklands wind screen. Got the latter from a Tamiya 1/24 Lotus Super 7, part of a used kit stash purchase.

Image

Yeah, that's going to work.

After 4 days working on the chassis, axles spinning free, gears set just right, Body does look great and will make a great looking car, We will just have to push it around the track right now. LOL

First test chassis done, a piano wire/brass one with features from one of Chris W's builds. Took some time to make it "flat and square" as emphasized by Chris.

Image

Image

Main rails are .055 piano wire with .032 flat brass stock for cross members and guide/axle holder tongue. Motor mount is a PN Slot aluminum one. Present gear ratio is 2.67:1 with a 9 tooth pinion and 24 tooth crown. Trued tires to 20.5mm. Guide is a cut down TSRF one to meet the maximum 7mm depth guideline.

Runs well but will probably add side pans for more weight.

Really not much room for side pans so weight, .030 lead sheet, added below the motor.

Image

Sheet's just thin enough to make the 3/32" (2.37mm) minimum ground clearance. Additional weight helped cut down the tippiness in some corners on my short and twisty track.

Wow, that looks great, and only four months left to tune it.... :doh: :roll:

Jewell like chassis fabrication.

Been trying to tame the handling. The car would topple over on a particular corner of my track (lower left) going anti-clockwise in the outside lane.

Image

Rather than soldering side pans to the piano wire main rails, I made and screwed a somewhat floppy H-shaped pan (.064 x 1/4" brass strip, .032 piano wire) to the motor mount, just making the minimum 3/32" track clearance.

Image

Image

The additional 11g, mostly to the outside did the trick. Now I can exit the corner without fear of flopping. Total weight's 79 grams with body paint and driver head to come.

Dan - nice job. I'm a sucker for a brass handling pan: I remember how excited I was to add an aftermarket brass pan to my HO AFX chassis the early 70's.

Hi JT,

Funny, you mentioned HO pans. Making this sparked the memory of an aftermarket one I put on a T-Jet many years ago. LaGanke is the brand that sticks in my mind.

Chassis's good so on to the body.

Sprayed Tamiya white primer.

A bit of sanding and then applying Tamiya French Blue.

Well ahead of the February 9, 2018 delivery deadline to Vancouver, Canada, the initial track hub.

I think I had this one:

Nice story about the HO handling pan era. I think I probably got mine around 70/71.
