I was hoping someone has played around with adding flaps to any of these three planes? Swordsman 18, Stuntman 23, Jumpin Bean. I was hoping someone can tell me what if any flight improvements? Tally ho Rosie

The first two have sheet wings and would be an easier do. I'd think though the additional complexity and limited line tension caused by the light weight of the planes in comparison to the larger .10 powered and up planes would have to be nearly frictionless to work successfully (i.e., sewn hinges). Also, the limited wing area coupled with additional drag of wing flaps may have a tendency to stall in maneuvers.

I think it was Dave Platt? who made profile sheet wing planes of around 30" span or slightly greater powered by Tee Dee engines for adequate sport stunt capability, but as far as I know, those were elevator planes.

But I'm certainly no expert in CL stunt design, so what I state is not necessarily fact, just my impressions. If greater stuntability is desired, I'd think a better proportioned plane such as Hal DeBolt's 26" span All American may be a better ticket for .049 flight.

Well now.... Frictionless hinges are something I must be seeing... does anyone have a link as to how to make them? Please let me know what you can. Thanks.

By the way thank you for the comments and attached pics.

LOL... OK Mr. Renger... I will build them for fun and for the kids to learn on and when I do that I will make some shorter sets of lines.  Shorter lines have always given me tighter lines. Right up to 6 ft lines in my mom and dads front yard. Glad mom had her curtains closed in her bedroom. Since both lines snapped at the same time and after the plane "simple beginners shoestring racer" ;hit the smaller wing windows if stopped the plane but the motor mount snapped off with a running black widow.... Until it wrapped up in the curtain  tumbleing and burpping all the way to the floor.  Wow mom sure woke up fast from her nap.

I was expecting the answers I got. If I ever wanted them for improved flight I would modify the wing to a full ribbed for any real improvement and I know it will not do the patteren nor make squared corners. But better loops and and good stunt capabilities. I say this with a known history of making 3 Swordsmans with jump in bean wings in swordsmans wing out line.

I will strip the parachute hinges off my stork and I did a general Google search for how to do figure 8 sewn hinges. I may switch out the pushrod from flap to elevator out with a threaded one. I will try to add pics. Lately the cell phone seems to be set to mega huge  clear pic setting and go over the 1000 limits.

Thanks team I really appreciate your help on these questions.

Those three planes, all of which I have built and flown in the past, are just undersize sport/trainer planes.  Flaps might help some but not much.  You are better off with a bigger, thicker wing and no flaps.  Flaps are great for big stunters but not necessary for smaller models.  The mechanics of flaps don't scale down all that well.  

I found that a 15-size Clown built light is a good .049 stunter.

Yup, at 200 sq.in. it is an excellent size for .049 power!
