Sporthawk Power Train Update

Sporthawk Update

Looks like the jury is out on the Sporthawk until next season.
The weather is getting cold here. So the Sporthawk probably will not fly again until next Spring.
The engine runs seem to be O.K. as the plane is now set up. So I am posting a current power train picture.
But the plane was a little wobbly on overheads. So I added a little more wingtip weight. But I have not flown the Sporthawk since the last modification. It is probably O.K. this way, but I can not say that for sure until it gets a few more flights on it.
Pictures to follow.
What to build next?...

Power Train-Rebuilt S1

Had to reconfigure the power train. Sent the venturi to the local machine shop for modification to take an O.S. control line fuel nozzle from the LA series engines. Installed a remote needle valve (O.S. R/C type) under the fuselage. Found it necessary to use muffler pressure. Am posting some pictures of the new installation because a picture is worth a thousand words.
This thing is really fast now!

Rebuilt S1 Ringmaster Update

Just remembered that the last post on this plane showed it after a crash. Since then it has been repaired.
The fuse has been shortened a little. And the tail feathers have been modified a little for strength and simplicity.

Mongoose Power Train

I was lucky to find a new McCoy 35 Redhead Stunt on eBay for around $35. just as I was finishing my Mongoose 2.
I used to run McCoys back in the late fifties, but I really have not had one since then. I remember them as user friendly engines. I remember them fondly. I think I had a lot of fun flying McCoys as a teenager.
I wonder what it will be like flying a McCoy this time...
The fuel tank is a Brodak 3 1/2 oz. oval wedge with standard vents. We always used standard vent fuel tanks with our McCoys back in the fifties, so it still ought to work today.
The engine pads are something new. We did not know anything about engine mount pads as teenagers.
The prop is a 9.5 x 6.

Finishing my Mongoose 2

The covering is Polycover from Hobby Lobby. The color is fluorescent yellow. But it looks like lime green to me. The covering is ironed over the balsa wing structure. No dopes or glues either under or over the covering. Polycover only weighs half as much as Monkeycoat. And it is very strong because it contains random polyester fibers. Great stuff.
The fuselage has one coat of water based polyurethane, one coat of Krylon water based primer, and two coats of Rustoleum (sand color).
A quick easy finish. And it looks O.K. for a finish on a sport plane if you ask me.

Just finished a Mongoose 2. Built it from a kit bought on eBay for about $30. There were a few parts missing, but the plans were complete enough that it was easy to make the missing parts close to the original. So this is almost a Mongoose 2.
The design is by "Fast Richard", Dick Mathis. It was kitted by M&P somewhere around 1980, I think.
It has a solid thick rib in the center of the wing. The motor mounts extend back to the spar and are pegged through the wing so the wing and fuselage are locked together. The front of the fuse is simply the motor mounts. The rear of the fuse is 1/4 inch basswood.

Sunday S.L.O.W. Club Flying Session

Beautiful November day. Sixty five degrees, sunny, light winds. Amazing. Lots of fun and flying.
Joe brought his new Twister. Great looking plane. But the pictures did not turn out.
