Default The SLICK STICK! (AKA, 3D for FREE) =)

Okay, just got back into flying recently and during a trip to the field, one of the guys mentioned that he had a .91 OS Surpass engine that he wasn't using. He also offered me a .40 sized Ultra Stick that needs recovering. Best part is, he gave 'em to me.

My dad just got a new 2.4ghz transmitter and I've still got 72mhz. He gave me his old Tactic transmitter and a receiver. So, I've got a plane with servos but no covering, a radio and a .91 OS four-stroke engine. So, my plan was to remove the flaps and ailerons, and make one big aileron for more control. I'm thinking about extending the tail control surfaces as well.

Perhaps it won't be some supreme-flying machine that will wow crowds and be the next big thing, but it might be fun. And, that's why we all got into this thing in the first place, right?

What are you'all's' thoughts on a project like this? Got any input? Anyone ever do this before?

I'm betting you'll have a great time with it! I wouldn't hesitate to fasten the flaps and aileron together. Keep it light! You may have to put the rudder and/or elevator servo in back to get it to balance without adding ballast.

I think I've got a set of working ailerons now.

The way the original ailerons/flaps were configured, the ailerons were way out at the end of the wing (out of the prop's flow of air) and both them, and the flaps were pretty short. My plan (we'll see if it's a GOOD one) was to bring the ailerons inboard more and give them a little more authority with a longer aileron. I've stretched the new aileron to fill the spot previously held by the ailerons and flaps. And, also brought the trailing edge of the aileron back further as it gets closer to the fuse. I think this will blend with the build of the airframe nicely and give me more control at slower speeds, thanks to the prop wash.



Since I'll be using a .91 four-stroke O.S., I was thinking of removing the firewall and trimming about an inch off of the fuse to move the engine back some (moving CG as well). So long as the fuel tank still fits, all should be good. It'll give me a chance to beef up that area with some triangle stock balsa behind the firewall also. Plywood firewall, of course.

Lets start with +1 on these ideas.

Next, see my avatar, that's me and my H9 .60 size stick. It has a 20cc Zenoah gasser in the nose, rudder and elevator servo moved to the tail. Battery moved to where those to servo's were.

I got the plane used and it had been built with the split flaps ( all the H9 sticks came with 2 sets of ailerons split for flaps and ailerons and full ailerons) also the manuals came with extra setup ideas for crow, flaperons and lots of crazy stuff.

Now like you I had some old stuff around. So I glued a little piece of balsa between the flaps and aileron making them one piece. I left the all the servos just where they were and made the linkages equal so each wing half is a two servo half. This let me use standard 3004 servos but now have 80 in/oz power in the halves. Too bad you already did the ailerons you could have done like me and saved some work and effort for somewhere else. Also because each ARF was sold with both sets of aileron there are a lot of them out there for free.

The fuse does not have a lot of side area and all the rudder is above the elevator so knife edge is not great, but, hovering, toque rolling, rolling hairiers and monster slips are good. You will get out what you put in for sure.

Great bash!

Thanks Kmeyers!


I did a little covering tonight. It's coming together. Although I don't have any crazy ideas of flying it this weekend. LOL! Once I get the wing re-skinned, then I'll take a closer look at the fuse. I even thought about building a different set of control surfaces for the rear. Might wait to see how it flies with the ones that it came with.

Tonite's progress:

Got a little further on the plane.

Decided to combine the newer scheme with the older colors. The layout is much more like the 30cc Ultra Stick. I just liked it better. I still need to add the blue onto the ailerons, but I wanted to mount them before doing that so everything would line up correctly.

After that, it's off to the fuse!

I wanted to check the CG before I covered the fuse since I may have needed to shorten the front of the plane with the larger engine.

I checked it with the engine installed and with the battery moved back, it'll measure out to about 4 inches. That puts it at the more rearward position recommended. I'll have to cut a door in the underside of the fuse, but I think that's doable. I'd rather do that than move the servos to the rear as some have done.

It was getting dark, but here are some pics:



It's hard to see, but I'll need to get some taller wheels! The prop almost hits the ground!

Getting closer to finishing the fuse.

I decided to shorten the fuse from the front for several reasons. The fuse already had T-nuts behind it and the new ones would have interfered with what was already there. Plus, there were sections that were already coming loose. figured that removing the old one, shortening the front to help with CG and getting good wood back into the game would be better than trying to re-hash what was already there.

I pulled a little over an inch and a half out of the front. The old tank doesn't fit between the firewall and the first former anymore. But that's okay. I got the firewall mounted with some epoxy and triangle stock. Then I stuck the engine on the front to check it out. I can pull the battery back up to under the wing and I think it looks better with a shorter nose!

Not sure why, but the previews are upside down but the images show right-side up.

Anyways, Here you can see how much I trimmed from the front.

Default It LIVES !!!!!!!

I fired the ol girl up tonight. Until now, I had no idea how the engine was going to run. I had seen it run years ago, but the guy I got it from reminded me that they could only get it to run with the idle screw all the way in. I fiddled with it a little bit, trying to figure out where it liked the settings, but when it was all said and done, it runs pretty good! Couldn't tell you exactly where the needles are set, but I can say that it does take a little idle mixture. =)

Here's a quick vid of the engine running. Hope ya like it!

Got a flight report.

Took the Ultra Stick to the field today and got in a flight. It became obvious that I could have taken more off of the front of the plane as when you lowered the throttle, the plane wanted to dive pretty hard. CG is just at the spar, within the measurements that they suggest. I know guys are running the CG further back. I may just do that, but I'll get it up in the air with more calm winds to determine exactly what it needs. Flew pretty good, and at just off idle. Just the way I like 'em!

Also took my ol' Senior out for a few laps of the airfield. =)

Keep us posted as I would like to see how she flies. I'm curious because I had a Saito 82 on my 40 size stick. It balanced perfectly and flew great. Seems like the 91 would be too heavy but let us know....

Ernie,

Had it out today and put some laps of the field on her. With the battery moved back, it flies pretty good. To add, I also needed to put some more weight (lead) on the tail. I put about 1.5 oz back there to get the CG moved back. Will hover fine and pulls out great. Just getting back into flying, I'm slowly getting more accustomed to being closer to the ground. I play about 3-4 mistakes high so far.

It was around 7 mph winds today and if I flew it slower, then you could see the wind buffeting the plane around. But if I gave it some down elevator trim and powered up, it cut through the wind pretty well. I can see why folks love this Stick design! I'm thinking that this will become my go-to airplane for some time.

I would think that your 80 Saito would fit fine and require less moving around of parts. I really like Saitos as well!
