Engines Cox Thimble-Drome Space-Bug Jr./Mc Coy Duro Glo Diesel .049
Hi Friends:
I am an airplane model who, surely like many of you, started flying control line models with engines from .049 to .35 and although I currently fly R / C planes and helicopters (sport level), I am still passionate about flight controlled by lines, but not I have found a local club where this type of model aircraft is practiced.
Recently my friend Alejandro Reyes gave me two engines, a Cox Thimble-Drome Space-Bug Jr. and a Mc Coy Duro Glo Diesel .049, both incomplete, so I took on the task of trying to restore them as best as possible to have them between my engines. of model airplanes. I did not intend for them to work as I only used the normal tools and cox engine parts I had in stock.
The Mc Coy engine needed the back plate; I cut one of the best possible way from a 1mm thick aluminum plate, this is flat and I understand that at some point the part that goes into the crankcase would be needed so that it could work properly, aesthetically it looks good and meets your goal to have it on display.
The Cox Thimble-Drome Space-Bug Jr. engine did not have the piston, fuel tank, reed valve assembly, gasket and needle valve and the spring, really the entire back of the engine! In this case I used a cox engine piston I had on hand and a backplate of a Killer Bee to which I cut the corners, in the same way as with the Mc Coy motor, I cut a 1mm aluminum plate to size and made the necessary holes. Aesthetically speaking it is not by far the best of works, but I think there is a better chance of working!
In both motors use high temperature silicone to seal the joints.
Greetings to all
