Superside racing sidecar F1 1/8

Hello everyone, I present my newest prototype, a F1 sidecar (Superside) scale 1/8, corresponding to the ribs of a car 1/10.
I realized all in order to run (if possible) in category "protoype sidecar" sleeves French Champioship bike next year.
I left the coast of Regulation FIM scale 1 and I ended up doing the following.
I opted for a belt drive to keep the engine just before the rear wheel and a maximum mass in the main axis of the sidecar as a scale.
Transmission parts from a TF-5 Stallion, F1 wheels, front of Pedal Popper.
It began with a "white mount" to see if anything can happen.









Possible settings are:


_ Ground clearance adjustable side wheel propelling through the eccentric belt tension.
_ Ground clearance adjustable wheel side of the basket with the original screws in the rear triangle.
_ Adjustable camber on the wheel of the cart.
_ Clamping eccentric adjustable thanks to the fixed axis of the triangle.
_ Hunting ground clearance and adjustable front with shims under the fixed triangles before.

With all that I hope the behavior will match.
These are the pictures in progress:



















Here it is finished, finally, to the frame part, remains the most difficult: the body.
I planned to put one together with LRP X12 6.5T engine but the concern is with the transmission upside down had to run the engine in reverse, but with this set you can not reverse the phases. .. so I put together a Mamba Max 7700kv
These are pictures of the finished frame:







Here is the outline of the future 2D body to be closer to the best of what is done at scale 1.

Fred, I hope that your template will be announced to the exact dimensions in the regulation because my body should be 431mm x 220mm precisely.

Those who have the mind as twisted as mine include the following drawing:





Once the bodywork finished it should be printed in several copies for those who would do their own prototype

For those who want to get into a replica of a F1 sidecar here the coast of FIM regulations for the chassis, scale 1:



Here is the link to the rules that will apply to the French Championship for the sidecar:

Thank you for the link to Lalain: top:

This is the progress of the template as a basis for recovery of wax:

This is the progress of the mold to the body, first I covered the master polystyrene with modeling wax. I finished the body naked virgin, without the pilot and passenger, I presented all on the chassis to make sure everything goes smoothly.
Then the hardest part was to "sculpt" the driver and passenger without making against undercut for thermoforming. I can assure you that it's hard to sculpt a character without "rounded" back.
The position of the passenger is not great but I could not take it to the top of the fairing, so I found this solution: a straight line position.
Once finished it I just had has run the plaster mold.
Tomorrow I make smoothing with coating.
Normally the first body should be released Thursday.
These are pictures of work steps:





































A quick little video, made between showers
No adjustment was made, the tires are worn with the same positive camber, which does not help:

excellent work, very pleased to see so much effort and work gone into an outfit, I am currently working and drawing up rough ideas for my own build, and had a very similar design in mind with the motor, lipo and belt drive etc, keeping as much weight as possible in line with the drive, a 40/40/20 wheel weight plan was my general aim

great build, beautiful parts and a great shell too, truely a credit to your abilities

that shell is stunning, wish we could get something like that over here, paint job is also top notch

Fantastic! Your design and engineering skills are very very good.

How much toe-in do you have on the chair wheel?
I think you have maybe too much power and not enough weight just yet in that video!

Looking good.
This is 1/4 scale, right?
Do you race this in the same class as the 1/10 Mardaves or in a seperate class?

its about 7.5:1 scale

430x220

anyone got a mardave shell to hand to see how that compares

looks like its about 50-70mm longer and about 20-30mm wider than the ones in the UK I have found sizes for.

Normally we should produce in small quantities when the body is "perfect".
The price should be 15 or 20 euros body, excluding postage. To this we must add the international shipping.
If you are interested in a body you can contact the store TOP OPTIONS in France by mail by filling out the form below: http://www.top-options.fr/contact_us.php

Well there it is now the first two bodies made ​​of lexan. It's not perfect yet because there is a fold but the next series should be better.
I will paint mine so that one realizes forms.
Special thanks to George's store TOP OPTIONS thermoformed to me these bodies. If ever some are concerned it can produce others.
These are the bodies:

I'm going to race in an other class: "Sidecar Prototype class" because the "mardave class" is a stock class.
