Help!

Best Cox .049 stunter


Hi everyone. I recently bought a Cox Blackwidow (stunter tank one) from the classified section. So basically im asking for ideas in order to build the best posible stunter for this engine.

I have a Goldberg Lil Jumping Bean with another Blackwidow, wich flies really good, but i enlarged the stab/elevator a bit. I dont know about other models or wich will be a good stunter. I know its difficult to find, but i prefer "slow" pace planes, that fast hornet ones; i saw planes very aerobatic but really fast, like combat ones. Well, im looking for the opposite: a real small stunter for this Cox.

Any help will be appreciated. I do have experience on building so its really not necessary (nor desirable) a kit, can be just nodel and ill find the plans and scratch build it.

Thanks and sorry for my poor english (im from Chile) and for the long post.

Here are a couple nice profile stunters for a Black Widow. All designed by Dick Sarpolus.

I had a Goldberg Lil Jumping Bean years ago with a regular Cox Babe Bee and it was a nice flyer with that build-up wing. Also build a few Sarpolus designs with TD .049/.051 and they fly well too, there is also the Nobler by Sarpolus:

Thanks for your imputs!!

Most likely my english its too bad, bud i want to build a stunter, not a race plane, and sheet wing planes are really really fast. I do prefer a built up wing like the jumping bean. I want to know if there ir a no brainer, like palmer or aldrich designs in .35 engines, but for cox .049.

Thanks!

No, your english is very good. Just to let you know that the plans posted here actually have very big wings and they are honestly not as fast as you may think using a Black Widow with 42 foot lines. However, I do not have anything off the top of my head with a built up wing for a Black Widow. I personally have plans for a built up wing full fuselage stunter here, but they are paper, and not in an electronic format. However, it is designed for a Cox TD .051 power. Also, if
you like one of the above plans, you can replace the sheet wing with a built up wing rather easily. Good luck with your building.

The built up wing and full fuselage 1/2a Snapper is a good stunter.

The plans are around.

New222: Thank you for your thoughts, but i have a couple of plank wing planes with Baby Bees and are really fast in deed, for me at least. The jumping bean (built up wing) are way slower and more maneuverable than those. Of course i can put a built up wing to a plank wing design, but also i can design a new plane, but i want to know if there is a common or succesful .049 stunter. Have no problem in design one, 25'' wing with nose and tail moments found in major stunters will fly good for sure, but i mean if there is someone used to fly baby flite streaks, small ringmasters or brodak kits for cox maybe he could advise to one or another plane. I will consider design of course, thanks.

DFHILL: Looks really good, i believe a full fuselage in a .049 is cool factor. Do you know someone who fly this?

Well, I made a long post with a bunch of planes, but I lost it. Not going to go through all that again, so I'll just say to look at this: https://www.aeromaniacs.com/Zinger.htm

Excellent suggestion. The best Half-A for aerobatics I ever flew was a Baby Streak with an Atwood Shreek ("Shriek"?) on it. I flew it on 40' of .008 steel lines. I always liked the look of Mathis' Pinto (supposed to be an 049 size Oriental, I believe).

There is a kit for the "Pinto", the plan was also available from M.A.N.:

Also "Miss Ashlee", more suited for a reedy:

Zinger looks great, but Pinto is a stunner. Anyway i believe a full bodied stunter is too much for a black widow, so i think the Zinger is a wiser choice. I wonder how it is conpared with the jumping bean and the baby flite streak. I - as son of a 76 year U-Control devotee - have a enormous respect for Mr. Aldrich designs. My father love his old Nobler more than me and my brothers.

PD: I always wonder how you americans fly small U/C planes with less than 45 ft. lines without get sick !!

I can't vouch for these but I am sure the baby Flight Streak, Ringmaster, Lightning Streak, Clown, and Mustang are good.

Forgot the link.

I found a man in stunthanger that produces really interesting 1/2A kits. He make a mini oriental and also the "hyper viper" the foam wing cox stunter but balsa made. He claims it weights just below 200 grams w/o covering. So far, do you think will fly good? Seems so to me!

I have one of those balsa Hyper Viper kits. Very good quality. But I don't know that I'd do it on a Black Widow. If you build it light enough it should work fine, but I'm going with a rotary valve engine.

Black Widow simply doesn't have enough power to fly a decent Stunt pattern at moderate speeds It'll fly like a moth and bog on up lines.
A TD often doesn't do well either. More noise than performance. Gotta gear one of those real low.
Personally I'd experiment with electric. Loads more available Torque which is what Stunters thrive on
If wanting Glo ?..Suggest at least a Norvel ...then simply scale down a 35 size Stunt model plan to suit .
Build it light and see how it works then try again... if necessary.
