My motor is an Axi 2204-54, so i was wondering if there have been any mini-bluebabies built. (I havent seen any under 22 inches.) Either way, i have 2 questions:

1) what is the suggested RTF weight of a Bluebaby 24" My motor is suggested for planes around 7oz so light is a good thing here. Plus, ive been looking for a solid, mini-backyard plane.

2) Can i scale down the 24 inch plans to make a 15-18 plane? Or can anyone help me scale them down?


Thanks for all the help here, ive been following this thread for quite a while now
About midway down this post is a link for a 12" WS BB

RC Fly Boy,

This is how I reinforced my wing. .125 carbon tube glued and taped in both halves, 0.0625 music wire, bent to match the dihedral, slipped into the two ends of the carbon tube.



survived several flights including a tight loop, plus one head in crash.

Oh, also have clear packing tape the length of both wings, doubled over at the joint.

Right, KFM's are all zero, UC is about 1/8 to 1/4 up at LE, and you can figure that into the saddle sides, about a Blucor thickness.


I just remembered that i'd posted on my blog how mine looks, may want to check it out.

Out of The Loop


Sorry to bother you folks while you are having so much fun. But I have been out of the loop for quite a while now.
I built a Blu-Baby AP1 quite a while back, and even maidened it last summer, I finally feel better now, and was able to get my plane up off the snow a few days ago, and I even got some aerial vid. I sure hope I am in the right forum for this thing. I am sure some one will straighten me out.

Well you are certainly in the right place. Your video defines amateur aerial video. Very impressive and a treat to watch. Simply beautiful. Thanks you so much for posting it.

Rob...

P.S. I encourage everybody to go to YouTube and rate this one. It should be well regarded.

Thank you so very much for the nice things you said about my video, Rob.
I appreciate your comments.
The video was taken with one of those $11.00 Gum Cameras off of e-Bay.

If I may, what vendor did you use to get the cam and were you happy with them?
I've been looking at them but not being an active ebay-er I haven't done anything yet.
Thanks!

I bought one from hobby partz. I paid almost 30$ though I never thought to check ebay. I am happy with mine - very simple to use. But does anyone else get interference from the planes motor? More throtle = more distortion. I get a wavy picture.

That is normal and some cams are worse then others. Best to get it as far away from the ESC and motor as possible. Not much else you can do about it.

If it is a swimming motion like you'll see here:

http://www.vom.com/jack/swimming.avi

A more rigid mount might fix it. It can be a challenge though. If the airframe is vibrating then you need to isolate the camera from that with some foam or something. If the wing is not vibrating, just the camera is vibrating, then firming up the mount or adding something like a layer of well compressed foam between the camera and the wing might do it.

I started with a thin, bendable for look angle, aluminum bracket on the camera. Then worked out a way to put that on the wing.

It the first two photos is the first mount I used. It was two loops of small bungee cord that went over the aluminum bracket. That worked fairly well but the swimming would come and go with air speed and motor speed. Folding a double layer of 1/4" RC foam (the white foam seen on the battery there) and putting that between the bracket and the wing, along with tightening the bungee cord loops, finally got it solid.

The next two are another flying wing. I drilled a hole so it was a snug fit on the short cylindrical nylon bushing and put the bushing in the hole in the wing. Then I put nylon flat washer on top and bottom of the wing and used a 1/4" nylon machine screw. The screw came up from the bottom, the camera rested on a piece of foam that was on top of the washer, then I put a 1/4" wing nut on it all. When it was snugged down pretty good it did not vibrate.

Sometimes is looks like I have too much time on my hands...

Can't remember if I posted this or not, but somewhere back in this thread, there was a mention of doing a dual rotor gyrocopter version of the BluBaby. If any of you guys are interested, here's the link to the thread in the gyrocopter forum: https://www.rcgroups.com/forums/show....php?t=1186165

I am getting ready to build a BB33 and need to order a motor. I know that there are bound to be posts in this thread that would be helpful, but there are 904 to wade through. I would like something on the economical side. I would like something on the upper end of the power requirement. I need some other things from HobbyKing so would prefer to but there. Thanks for your imput
