My New Sakitumi Glow Power
« on: January 07, 2018, 09:41:51 AM »
About a year ago I finished my Sakitumi Electric, and it has become my go to plane in all respects. See here- https://stunthanger.com/smf/open-forum/builtright-flyright-sakitumi-e/msg507748/#msg507748 I decided not long after that it would be cool to have a glow powered version also, and put in my order with Walter. Not too long after, I got the kit. While other projects had to be cleared out,it was always in the back of my mind and about a month ago I cleaned off the bench and went for it. Just like the electric, it was a pleasure to build. Factory OS LA-S .46, APC 12.25x3.75 prop with a custom cut Dave Brown spinner. All iron on covering, rustoleum rattle can for the LG and wheel pants. Weight is 1 ounce less RTF than the E Version RTF. Balance is perfect. Can't wait to fly it!

Nice, tell us about your gear struts.  Is the Sakitumi and inline design ?

I like it.  What kind of fuel tank is that?  Could you show pictures of your tank mount as well?

Thanks guys. It's a Kraft/Hayes 6 oz tank. I'd show you pics of the tank mount, but it's kinda covered up by the tank. It is two rectangles of thin G10 fiberglass with separator pieces for the tie wraps to go through. The slots on either end allow it to be adjusted up and down. Allan, the Sakitumi was designed by Elliott Scott. The landing gear comes with the kit, I got the machine shop guy at work to put lightening slots in it.

The Red one is HK covering, the Green one is Ultrakote and Monokote. All work well, IMO.

Allan, the Sakitumi was designed by Elliott Scott.

   That's the name he gave us, at least.

   It's a competitive stunter as it is. I have a 560 score to my credit with mine. And I finished 8th! But only about 20 points off the podium.

I still don’t understand how he can be spotted in four different places, around the world, at the same time.

2 versions, one flapless and one with flaps - Both using current moments and airfoils.

The more I look at these pictures, the more I think I gotta go back and put the white on the wingtips of the red one... gotta get on that tonight. Would be nice if the weather would clear up enough to fly either one this weekend  #^

What does trim solvent do?

Is this airplane consider a precision aerobatic airplane?

Allows layers of film bonded without heat, and therefore without bubbles.....

Yes, for monokote on monokote. Make no mistake, as with everything there is a learning curve, but it is great stuff.

I would think adding flaps would require a radical redesign of the wing structure.

Elliott Scott is the original designer and is well aware of what it takes to make this airplane fly well flaps or no flaps.  :)

The Sakitumi flies an excellent pattern “as is” without flaps and its airfoil is designed with a very forward high point to ensure it doesn’t need them (the airfoil is inspired by full size aerobatic plane designs NACA 0016).

My old prototype Sakitumi has taken me up the ranks to first and second places. I use an LA 46 with 12.25 x 3.75 Prop, but a good 40 with a smaller prop will fly it well. If you can use a smaller prop than the 12.25 x 3.75 the corner improves even more than the “blinding” one a Saki can already do.

Walter Umland kits the design and also makes a 25 version for the LA 25, which I hope he will make more public (hint, hint).

Well, I got it out yesterday. Only got in one flight then the rain started, but damn it is awesome! Flies great, needs very little adjustment. I took a little weight out of the wingtip when I got home, and next time out I may move the leadouts forward a touch. It pulls pretty hard, but it isn't uncomfortable. Power is pretty similar to the electric. I am tickled with it!

The Sakitumi reminds me of the Teosawki.  To me, the Sakitumi is more visually appealing.

The Sakitumi is a newer version of the Teosawki , hence the play on words with the name.

Yes the clear covering shows off the great laser cut parts   If I didn't already have so many projects I would get one.  Especially after seeing Dan McEntee's version fly. H^^

I got in 8 flights on the glow version yesterday and had a BLAST, it is just delightful. Gotta say the LA 46 is a gem, starts and runs like a champ.
