RE: Twin ID?
I had a Midwest Twin Stik in the late 70's, early 80's. Actually, I still have it. I originally powered it with 2 standard OS .25's but changed to OS .25 FSR's, more powerful motors. I enjoyed flying it and eventually retired it when it started flying tail low. I still have it as it is pretty ratty looking as I covered it with something called Fabricote, from the Monocote people. Terrible stuff. You had to CA the edges constantly as it didn't stick to itself very well. Also it looked dirty and couldn't be cleaned. I've often thought of re-covering it, but since I'm into electrics exclusively, it's probably not worth it. I loved it for the "gee whiz" factor as it was the only twin in my club at the time.

RE: Twin ID?
Jenson made a Twin Stick, I bought one used and empty but for rolled up plans inside at a auction once, my first twin.
Lost it on a high speed pass down the side of the runway due to a faulty battery pin, instant down elevator.
Very exciting to tune and fly your first twin. (OS 40-FP)

RE: Twin ID?
Looks like a Cedar Hobbies Twin Stik...I've had a couple and now have one NIB I found left over at a LHS.
Tyey are geart planes, but very weakly built. I did some mods to strengthen them, but they fly really fine and are very forgiving...land like a dream and fly just like a Stik. Only real problem is the engines are very close to centerline (that's good!). but since there is no fuse between the spinning props, one has to be very careful starting engines.
Cedar Hobbies has been out of business for some time...wish Nitroplanes or somebody would import these again.....Bo

RE: Twin ID?
The Twin Stik is (was) a very old balsa kit from Midwest. I took one up on its first flights for the man who built it but I didn't like it at all. It was sluggish, had lots of drag and was underpowered. I told that to the owner and he went out and bought two new OS .25FSR.
I never got to see it fly with the OS .25's because he flew it himself and crashed it in a swamp and never recovered any part of it. I mourned the loss of those two shiny new "expensive" .25FSR's.

RE: Twin ID?
It is not a Midwest Twin Stick-I have flown those. As someone mentioned, it's a Cedar Hobbies Twin Stick. I bought 2 of them. I built one and flew it for 3 or 4 years. Great flying Stick; and it flies just like a Stick.
I used 2 OS .46AXs/11-5 APC props. Those engines would sing. The plane had vertical capability and was very aerobatic. Lands like a Stick, but maybe slightly faster.
Notes:
1. I used a wider landing gear. If it tips taxiing, you'll get a prop.
2. There were reported problems with the nacelles coming loose. I squirted Gorilla glue in the rear of each nacelle and let it cure and expand into the gaps. I never had a problem.
3. I builds nose heavy. I added a Sullivan tailwheel assembly and a separate servo in the rear.
4. I added 2-56 rods for a tail braces.
5. And I cut a compartment in the rear fuselage for the battery, all just to get the CG near correct.
6. I used Ernst Thrust Plates from Tower to put in 7-8 degrees out thrust in both engines. When you lost one engine, you'll hardly notice it. I could do acro on one engine-rolls both directions, Immelmanns, loops, Cuban-8, spins, etc. The out thrust takes care of the yaw.

RE: Twin ID?
Definitely a Cedar Hobbies Twin Stick. I have been flying for years, one of the first ones Cedar Hobbies ever sold. Mine has been flown with tin Magnum .40s, Magnum .52 4-strokes, and now with electric motors. Really good flying plane, and engine out is almost a non-issue, even with "0" thrust lines.
Here's a vid of the elctric conversion flight: http://www.youtube.com/watch?v=8nzzD16EwUg

RE: Twin ID?
Of course I put the servos in the back for balance. I build all my planes without the rudder & elevator servo, then check the CG. I rubber band 1 or both to the rear to see if that helps. If it does, I cut holes and mount the servo. I add a little piece of 1/8 ply where the screws insert.
In the photo you can see that the battery is over the pre-installed servo tray. In addition to moving the 2 servos to the rear, I cut a battery compartment in the rear fuselage, added 2-56 tail braces, added a Sullivan tail wheel assembly with a servo in the rear bottom. The plane was really nose heavy and I hate to add lead.
I think the Twin Stick was designed with something like OS .40LAs or maybe .25-.32 sized engines. The .46AXs just added too much weight forward. But it was nice to rotate on take off and climb out vertical.
As I recall, Midwest never had an ARF Twin Stick. If the owner looks at the construction, he'll see the hot glue used to stick it together,

RE: Twin ID?
Once saw one "Shuck" an engine in a high speed pass. Two Mag 52 2 strokes screaming and the hot glue gave out releasing one engine from the wing. Lawn Rake time.
Impressive but poorly built........[:@]

RE: Twin ID?
I had a plane just like it, for a while....
Bought it at a auction, was a Jenson Twin Stick with stamped aluminum motor mounts, my first twin.
I put OS 40-FP engines on it, my original trainer motors and it flew great, for 3 flights.
While making a high speed low altitude pass down the side of the runway I lost the battery connection which I had trouble with the flight before while still on the ground, thought I had fixed it, I was wrong.
