Wanted - plans for .60-.78 size plane - 8/18/2003 6:21:25 AM

I would like to build my first SPAD for a MDS .78 engine, which is presently on a banged up Sig 4 Star 60. Something with the flying characteristics of an Avistar/Hobbystar or 4 Star would be
great. While I have not built a Spad I did build a US Aircore a few years ago, though I don't want a really complicated project on this one. Any plans to share?

Deadeye did an AWESOME job on his CorStar. No plans, he pretty much went from the plans.
I think with pre-colored coro you can make one a little lighter than the balsa version.

*Blushes* Why thank you, Crash. And that Cor-Star now has 60+ flights on it. 1 Cartwheel (busted wing blocks out - fixed in 20 minutes) and I've busted the landing gear block 5 times. The one I'm building now, is purple coro, (Rustoleaum paint IS fuelproof, but doesn't stick to coro worth a darn) and I will be fiberglassing the wing and LG blocks to the blasa interior frame BEFORE I poly glue the frame to the coro. That should make her about bullet-proof.

Wings are done, but due to the huge amount of flying I'm doing lately, I haven't worked on her much. If I just sat down and did it, I could have it done in 10 hours or so. I took out the balsa one with the Cor-Star a few days ago. Flew one, then the other. I can defintly notice the pound of difference between the two, but performance is nearly identical. And landings? Four Star creeps in about 7 MPH without flaperon, Cor-Star about 5 MPH without flaperon. Can't get the Cor-Star on the ground! It just floats and floats. It's airfoil is flatter than the Four-Star.

I have been flying for a year now, and have NEVER had as much fun flying as I have with the Cor-Star. She is my baby. *Pats Cor-Star on the canopy, hugs wings*

Perhaps you'd like to be alone with it???

Well, how about something a bit simpler - maybe a box fuselage
with a 6' semi-semetrical wing. Perhaps something like the Tower Hobbies Uproar style of plane or a larger version of the
DuraPlane DuraStik? I had a Durastick, by-the-way, and the
wire broke off the switch on the 79th flight. From about 150 feet
you can destroy one of those planes.

Try this out. I took the basic plans for the SpadStick but made it low wing. I made the wingspan 50 inches. I have been flying it on my MDS 40, but I have an MDS 68 comming in the mail...should be here Friday. With the 40 I can do basic stuff, but this thing is just begging me for the 68

On my website you will find a spreadsheet to help scaling the SpadStick design up and down. I make mine with a simple box fuse...I don't taper the tail. I don't have the patience to spend that much time on doing that.

I didn't pay attention when I put the electronics in and got mine tail heavy. I had to add some weight to the nose. Switching to the MDS 68 will help with this too. I REALLY like this plane. It floats in on landings yet will keep me busy with it's aerobatic abilities.

Here's a quick picture...but go to my website for more info:
http://www.rcsites.net/qcoldir/

I surface mounted the servos on the top of the fuse, so I built the simple canopy/turtle deck to cover them up. The pushrods just run on top of the fuse back to the tail feathers. I bent the rod going to the throttle and routed it back inside the fuse through a slit in the fuse up to the engine. I hate pushrods hanging out and not covered up.

The canopy is just held on with clear packing tape so I can take it off to make adjustments.

You'll find many people, including Tileflyer that have converted the SpadStick to a low wing plane. Just ask for help if needed.

Oh, one more thing. If you are gonna power it with a 60+ engine, just build the entire thing from 4mil coro...don't worry about 2 mil for the wings if you don't have it.

For a simple design build a plane very similer to a deb except use canadian pipe if you can get it or build a coro fuse around americain pipe formers 40 inchs long. Build the wing out of 2 mm coro straight wing no diheadrial wing flat or symmetric wing with a wider chord say 14 to 15 inchs. 60 inch wing span. I built one like this with a canadian pipe fuse 40 inchs long a 2mm symmetric wing with 3 inch rons total chord 15 inchs. powered by a saito 91 and she is a blast to fly. she turned out 6.5 lbs. The symmetic wing only seems to give a tad bit better roll rate over the flat bottom wing. Its harder to mount also. On the wing i used a single spar made from 1/4x1.5 lattice. Look at the BUHOR wing for a singe spar 60 inch wing. Its 4mm but just do the same with 2mm. 2mm is much eaiser to work with when building wings.

Well,
Thanks for the great ideas. Quicker, I went to your website (nicely done by-the-way) and ran the spreadsheet for a 72" wing.
This looks like the design I was hoping for. I noticed you are using a lot of 1/4" foam board in some of your designs. On this bigger design would you recommend coro or foam? Is one or the other more crash resistant or easier to work with? On those floating landings - I have found using a large prop really helps reduce long floats as they slow the plane down more-so than the smaller props. Going from a 12x6 to a 13x6 makes a difference.

I'd go with coro. I've just been playing with the foamboard. By nature, the coro is fuel proof, whereas the foamboard is not. To fuel proof it I've tried clear laqcuer, clear spray and clear packing tape. I'm using the packing tape method now because it holds up better, but it takes a LONG time to cover an entire plane with 2.5 inch wide tape strips!!!!

It's been fun, but I'm going back to coro for the bigger planes. I'll stick with foamboard for my .25 sized planes.

What I do like about the foamboard is that the flat bottom wings are FLAT, no warping. They've held up well to mishaps and crashes. I might keep making wings that way, but coro is the best way to make a lite, strong fuse.

What plans? The CorStar does look awesome! Do you have any basic dimensions?

Actually, I just used the profile of the ARF as my only plans. The biggest thing, is that the turtledeck is a seperate piece, so it's a fairly boxy fuselage to cut out...goes together just like most other SPADS. I'm don't think it would be possible to make an identical fuselage without plans or an existing 4* to draw from.

Everything else was measured from the ARF (tailfeathers, etc.), and transfered to templates. It would be quite a challenge to build one without a 4* sitting right there in front of you. I referred to mine ALOT. It would take me a couple of days to have detailed plans up and running. Unless we get a monsoon in MT this fall, it's going to have to wait till winter.

riesiminski - you have a very good website as well.

I downloaded the SpadStik design from SPADTOTHEBONE and have scaled it up from Quicker's spreadsheet. I still want that 72" wing and I expect I will have to build it in two pieces and
stick them together as is done on most larger balsa planes.

Any advice on building the wing in two halves? I might also add
a couple of degrees of dihedral.
