Took one good running nothing-fancy Sceadu and put some new clothes on her. Enjoyable build and hope to fly her soon weather permitting. A bit about the build, instructions suggested fiberglass cloth for inside strengthening. I chose to use .030-carbon sheet and slow cure epoxy. Fueling the bird was the next decision. Since this is an OS and not YS that meant a fuel clamp to engine would be needed in fueling and a way to know you filled the tank and not also filling the muffler! Plumbed in a Tetra “Y” fitting at the top of the tank, one tube to muffler the other to a nice fitting on the side of the fuse. As you reach the top of the tank with fuel the hose on the side of the fuse will start spitting. Tank full, case closed. Using an old pattern airplane technique I used two fittings on the side of the bird that allows me to fill from there and disconnect the engine side during fueling. A filter is also in line inside as well as a header tank. I did have this trick one piece plug in type fuel connection but it required a bit of force to use it, more force that I want the side of the fuse to see on a repeated use. As for not seeing the fuel level during flight I will use a radio timer. Glo ignition is handled by a push&glo system with the button right inside the front air intake as well as charge wire/battery connections. The muffler is a HN-50 type F Funtech, a work of art by any means, and also one that is required to work/fit with the fuselage. The tail-case was a bit involved as well in fitting. Black’s fuselage is top quality, super light.

Hover update- Fueling system worked as expected, needed two clicks of forward elevator from when the bird was stock. CG may need a tiny bit more weight. No vibrations/odd sounds, rock smooth, super quiet with a very nice sound from the Funtech. Touch and glo is cool! Flight this coming weekend.

The Funtech pipe is really nice it adds to the hirobo bling factor

Nice, Mike......

CG OK with the ali boom?

Think maybe a cooling shroud extension would be a good idea for the summer?

Added two ounces of lead to the front. Bird weighs 8.9lbs. We will see soon as how close I got it. Tank was half full too. I pondered about additional cooling Ben and it may need it.

Not bad. If it really flies well, it would be worth the money to get the SD G carbon boom. You'd likely be able to take out at least half of that weight.

On RR several months ago. MRC has two unpainted ones for the Sceadu. May want to ask them if they have any for the Freya.

Finally had some weather to get a test flight on this bird yesterday. Wow, really picks up a head of steam and goes. Basic race track ovals, stall turns, about 1800 rpm head speed. Just a shakedown flight. She is doing well. Adding a few vents towards the lower rear to add a bit more airflow out. Smooth and and very quiet as well. Next time out will add loops and rolls.
