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 (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.

That looks great Bill. Are you using the hobby king coverings?

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

Its an in-line design. A derivative full body version is on my building table right now.

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

Will this one have flaps, going to be a competitive PA stunter ?
-
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 #^
-
Agree 100% Bill.

Aaaannnnddd there ya go. Man, if you haven't tried the monokote trim solvent, run don't walk to your nearest tower hobbies. It IS the shizz.

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.
-
Elliott Scott is the original designer and is well aware of what it takes to make this airplane fly well flaps or no flaps. :)
-
Years ago Roy Tranthom gave me one to fly. had a double star 50 and it flew incrediably well without flaps
-
I would think adding flaps would require a radical redesign of the wing structure.
MM
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!

Is it a written rule that all Sakitumi must be covered in clear? I know I did! LL~ LL~ LL~
-
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.
-
Very Nice, but seriously dude that pool needs attention.
-
hello to all,
Just started to fly again. I am a glider guy. For the elevator flaps and aileron's we use sealed hinges, no air can bleed between the elevator (in this case) and the hinged part, and is therefor more deficient. Could this be used in a u-control?

Hi Peter;
I am a former glider guider, and we not only seal our hinge lines, there are several threads about the best types of tape to use. Try using the search function for that and see what you find.

John Rist
no, they do not have to be covered in transparent film. VD~ VD~
-

Hi John, I don't think anyone has set up any rules that all Sakitumi's have to be done in clear or transparent covering/colors. But you sure do have to admit they really do look so cool and it sure is nice to see the cleanly constructed wing.
Oh B.T.W... John, can you please send me some pictures of yours for my website.
-
Great looking planes. Every time I see that name a certain image always comes to mind.

I ran. Tower Hobbies does not list Monokote Trim Solvent. Put word "solvent" in their search and you get nothing. Also not listed under Covering Accessories. Where did you get yours? (Unless it was 20 years ago..)
-
Try using acetone, I believe that is all trim solvent is. ;)

I made that post in January of 2018, and had got the trim solvent from Tower Hobbies that week. I don't know if acetone will work, it smells nothing like acetone.

Bill you did an awesome job with both versions.
Looks really good in red, I think I need one myself in red.
-
Topflite as a brand is all but dead....no more models, arfs, kits, monokote, trim strips, solvent....all gone---- only remaining stock at folks like Graves RC...etc....
bottle of Top Flite MonoKote Trim solvent sez: cyclohexanone dihydro 1(3H)-furanone and petroleum hydrocarbon
too lazy to seek the MDS ....but not Acetone, MEK, or Xylene....I seem to recall one forum claimed it was actually a Nitro Methane / or Ethane derivative but I am no chemist....perhaps raw nitro does work...dunno

Thanks, they are both still flying and doing great. It's a real fun build and I love the way they fly.
-
Is there a kit of this thing. Looks like a real fun rig!

Walter Umland sells kits of this plane.

I've built both the 46 and 25 size, from Walter Umland's excellent kits, and can recommend them highly, despite the demise of the designer, who obstinately continues to deny being deceased.
