When I found that the motor was bound by the Loctite, it very nearly flew into the bin with the first few ruined shells(don't ask). But the thought struck me that the physical reality was not dissimilar to what we routinely do to axle/bushings to reduce slop and improve fit.
So, I introduced a slippery concoction, clamped the motor shaft into my Dremel chuck, and drove it hard, included side loadstill it would run freely under it's own power. I'm hoping that some race miles will free it up further and it will regain some speed. I also fitted ball races to the rear axle, so hope to even out the drivetrain drag a little that way.
Here's hoping, We'll see.
Curious?!? My repop (thanks Phil) of an early Scalex seems to be a little longer than those other 804s

Reason: Well look at that...!
A brave experiment. What dissolves Loctite? Oil doesn't seem to. Maybe a hotter solvent is needed, like MEK, or toluene. I gave up trying to free my motor, pulled the can apart, and cleaned out the bearing by hand. Unfortunately I bent the brushes re-assembling the thing.
Since Haystack has a motor issue before any real testing or racing would you all agree to let me install a new motor for him now? I do not think that with all the drag the Loctite has on the motor it will last the entire series. I have a spare all ready to install for him. Haystack you have to agree to let me work on your car also. It would be sporting to give this Tasmanian entry a fighting chance. Ken

Happy for any ministrations to Porsche, whether heat or remotor. If car needs to be dissasembled, the rear (and only) screw is only to stop the back of the shell from bouncing around, so consequently is a loose fit. After removing screw, hold chassis by front wheels with the pan facing you, place thumbs under the nose, and gently but firmly push until shell pops off axle tube. Epoxy body has some elasticity, and slots are angled to form a clip of sorts.
Cheers, Chris
P.s If consensus is NO, then am happy to proceed as is. It's all a happenin' thing.

Light car that has home track advantage. Had so many laps in testing that I replaced the motor for good measure. Not the fastest on the straight and a little loose for a nice drift through the corners. Ken
I vote to allow the motor replacement on Haystack's car. This is classic F1, the era before big sponsorship money destroyed the "sport" and imposed "Big Business" rules. It simply would not be sporting to force him to start with a bum motor.
Ken, beautiful-looking Lotus there. I look forward to seeing some more pictures of it after concours judging.
This proxy has the "feel" of what IMO a proxy should be about,everyone sharing and learning from the experience. Change the motor BUT reprimand him for leaving the build so late, no one else would leave it so late to build a car.
News from the pits. . . . Haystack's Porsche had a successfull motor transplant. Straightaway speeds have improved and it does not lock up the tires without the brakes hooked up. . .
