I will modify Mike’s design a little
in his design pipe goes inside the fuse and header occupies tank room so he had to bring tank back into the canopy therefore a pumped engine is necessary.
on the other hand cooling the pipe is a concerning issue.

I canged the pipe position from inside the fuse into a Conventional half tunnel belly, this way header will not occupy the tank room back to the firewall, so I will move the tank forward and will run the engine without pump.
cooling of the pipe will be much better and there will be more room inside the fuse for servos.

the other modification is a take apart wing and also fixed carbon fiber landing gears on fuselage instead of retracts.

This is Mike’s original design Note the header occupying tank room and the pipe occupying servos room without enough cooling and the tank position in canopy which needs a pump to feed engine. Of course Bringing the tank forward will produce some CG problems during flight. Ehsan

Not sure if it really helps in reducing weight, but I had enough time, so why not to do that?

Another nice build. I scratch built one a few years ago and had the luxury of the glass fuselage top to speed up the build. Great flying airplane!

Hi Will, please share some pictures of your plane if you still have it.
What was flying weight and also the power plant?
mine will be powered up with a Super tiger rear exhaust, my estimation of weight is about 3200-3300 grams.

regards,
Ehsan

I always use 100 gram glass cloth and some epoxy to reinforce sides and joints, it’s much lighter and easier than plywood doubler.

Making the firewall by laminating three pieces of 5 ply 2.5 mm plywood.


Using some CA to tag motor mount on firewall, then drilling screw holes.

Hi Ehsan,
Flying weight was around 7.5 pounds powered with an OS Hanno Special. Also fixed gear. I did modify the wings (and maybe the stab) by reducing the tip chord and the tip thickness. I will try to find a photo.
Your build is progressing very nicely. Great craftsmanship.

Thought you might enjoy these. This is from the NATS in 1990 when I was competing with these guys. M. Klein was Mconville's buddy. As I recall the plane had not been kitted yet.

Note in the second pic Chip Hyde photobombing this.
