What size motor would suit an 80" Stick? I prefer overpowered of course

arobatx

what does it (or is it expected to) weigh?

jrjr2u

Well, the specs say:
9 pounds without engine
Engine Size .90 - 1.8 2 Stroke or 1.2 - 1.8 4 Stroke

arobatx

Well, in my experience anything over 10-11 lbs (with engine) would be pushing it for a 26cc Gas, unless it was on a tuned pipe, and even then not too much more for the 'overpowered' feel you are looking for. And I am defining 'overpowered' as enough to fly the plane with 3D aggression.

Between 11-14 lbs my best guess would be the 35-45cc range, and between 15-18lbs start looking at 50-60cc for that kind of power.

Now you need to research the engines available in the weight class you are anticipating, and go from there. Remember to watch your wing loading!!!

I have a Homelite 30 on mine. It has plenty of power.

Good to know thanks!
How hard would it be to make that a 2 piece wing? I'm thinking not that bad eh?

The wing on this one has spruce spars and plywood doublers in the center. Then 1/16" cheek plates between the ribs to the tips. It doesn't flex at all. Plane has the fabric type 21st Century covering.

No dihedral.

I'm not too sure how to go about it but I was thinking a couple of aluminum tubes around 10" -14" or so and some nicely drilled holes to accomodate them Maybe some more doubling in that area too. Should not add more than a few ounces to the total weight. I havent bought the kit yet.... still in the thinking stage

There are two different versions of the Bridi Stick floating around. There is the Bridi Stick and then the Bridi Old Timer. The only difference is the picture on the box. He dresses the Old Timer a little different. The wheels are not in the kit anyway. Mine was bought as an Old Timer but I have a "Stick" Kit that I haven't built yet. I changed the wheels back to "Cub" ones on this plane.

The plane is built heavy enough for a 45 engine if you want a hot rod.

My Homelite 30 was a new "Short Block" back in the 90's. It has an unknown chain saw flywheel but the ignition module is from a Homelite 25. The carb insulator is a bored out Homelite 25 model. The carb is the WA167-1 from a later model Zenoah 23. The prop is a now defunct Dyna Thrust 18-8. The muffler is from Carr Precision but he no longer sells this type. I made the back plate myself and it is copied after the C-H ignition back plate design. I use a 14 oz tank. Seems to be plenty for me.

I wonder how well this would fly with a Toro built by Scott?

I've been looking at this for a while myself.

Mine originally had a early model Zenoah G23 two port (Kalt 22) which were anemic devices. It turned a 16-8 at 7000 which is 1000 rpm less than the later G23. The airplane flew but it was obvious that it was under powered. The climb wasn't very steep.

So I would assume that it would do well with one of Scott Ellington's engines. The smallest he has right now is the 26 and it would work fine.

My Great Planes Giant Big Stik has about the same specs... It flies great with the Poulan 42cc that I have on it.

I have one already stripped down and ready to send him.

I have an electronic ignition to put on it.

How about nose weight?

Do I need the flywheels added weight to balance the plane?

If I remember right the engine weighs about 3 pounds.

Mine has the elevator servos (2) mounted in the rear and I have the flywheel on the front.

If your servos were all in the main compartment it would most likely balance fine with the CH ignition.

The original that Joe Bridi built had a Super Tiger 2000 on the nose.

Anyone know the difference between the original Bridi Stick kits and the ones that Bluejay are selling now?

There's not any difference that I know of
