Sure why not .I'm already saving money by having water with my cereal. Times are tough ..gotta save for more arrma partsJust add water! Get to work!!!
Could you vacuum form a sheet of Lexan over a plaster mold in theory (i know thats not the purpose of this particular thread)? Have you tried it before, was it successful?
Mr Koder will never be the same again because of what he sawIf you ONLY knew...
I've been to his workshop , yeah he's done that process before.
My mind was Blown Up from what I saw with my own two eyeballs..
-He's accomplish a whole lot in that little shop of his.

Yes but nothing very large. Getting enough heat into the plastic has been a challenge so far.
These are plaster covered in filler primer, wet sanded to 1000 grit, then waxed and polished to help the plastic not stick.
Dammit, there goes any plans for that then. How have you been heating your plastic. I've watched a few home vacuum forming vids on you tube, and people have been doing anything from sticking in the oven to building dedicated heating units.
There is certainly a learning curve and lots of frustration when the plastic folds and does not form as you might expect.Thanks for the tips and tricks. I would only be looking at building a one off for myself if it were feasible. But it would be large scale, think xmaxx size.
I'd probably take an existing lexan shell i like, make a plaster mould extend it length and width ways as necessary, then try to vacuum form it.
If im honest if you had that much trouble with it i doubt it would be worth the time and effort for me to attempt it.
Will you have a center support for the wing as well?Decided to use my lunch break in a constructive way.
If the rear was not extreme before it is now.....
I figure I can pickup a different aluminum shock tower for use with this body and take this rear section to a more extreme level that it deserves to be!!!
Removing the center section further up into the mid section, or in other words starting that slope earlier will help bring it lower to the ground while retaining an angle that will not create airflow seperation/turbulence. Red is the new body cut that takes about 15-20 mm more out of the center.
This was the "new" plan from near the shock tower back:

Busted out the angle grinder and rigged up some cardboard with my shop vac in the center to catch the blast:
Measured around 15mm further down at the shock tower (indicated by the silver line). Made the first cut and then went hog wild....

NOW I am happy with this shape and design.
This is more of an uncharted RC territory where I like to find myself
I am basically creating this if you need a visual.... the rear deck comes down to meet the diffuser. The side plates support the wing to generate the downforce needed.

Good eye and thanks for calling this out!Will you have a center support for the wing as well?
Sweet! I’m sorry if you explained and I don’t understand, but will it brace against just the body? Or will it go inside through the body?Good eye and thanks for calling this out!
Yes, but I decided it will be built into the wing and not the body.
The plan is to 3d print it and have a channel inside the airfoil for a small aluminum angle iron or square tube to fit that will help it resist flexing + the center support.
Yeah just brace against the body. Since the body will be composite (fiberglass or carbon fiber) that won't be an issue to do it that way.Sweet! I’m sorry if you explained and I don’t understand, but will it brace against just the body? Or will it go inside through the body?
Is the aerofoil of your rear spoiler going to be a tested documented profile similar to what he attempts to do here in forged carbonor more of a wing it and see how it turns out affair(pun intended)?
Perfect! I didn’t know, but I was pretty sure lexan wouldn’t be strong enough to make it stableYeah just brace against the body. Since the body will be composite (fiberglass or carbon fiber) that won't be an issue to do it that way.
If this was going to be a plastic body you would want it to be supported by something connected to the chassis like the shock tower etc...
