My Elf's

My Elf's 18, 20 and 22"ws: top left and center: 20" ; right:22"; bottom: left: 22"; center and right: 18""
the 18" has 80 sq in and 40 gr auw; the 20" 100 sq in and 42 gr; the 22" 120 sq in and 48 gr auw.
6400 brick, clear end bell motor from champ; 160/70 prop; cirrus esc with brake; 110 t0 160 mah cell. 1 and 2 mm depron.indoor or no wind outdoor. more details in my blog or at the indoor and micros.
simplest thing to build, and the closest to a paper plane i ever had. trainer and sport backyard flyer.
i fly it at my backyard whenever there is no wind at dawn-just walk a few steps and there i am, practicing take-offs and landings from a walkway, very much as aircraft carrier style-or catching it.
never had so much fun-and for pennies!

AUW is going to be right around 4.2 Oz in 5 channel mode (A/E/R/T/F). The 5g motor seems to have a lot of power and it should fly like a Warbird. The 2S 360 Rhino gave me 7+ minutes at WOT throttle with a 5043 prop in bench testing so flight times should be Huge.

These models are great fun to build and modify for cheap so I ordered 3 more today.
how did this zero fly? I know they are 2x times the weight of a UM P51 - but with that brushless it should have flown well?

It flies great. The AR6400 is the best set up for the cox/gravity micro warbirds to keep the weight down to 115g or less.

Here is my favorite windy day flyer. I saw the post on the dyke delta and had to make my own version. This is to date the best flying wing I have piloted. I will not hesitate to fly on windy days with this plane. Will fly it in the Gym in a couple of weeks.
5 gram brushless, orange 4channel dsm2 and pentium 6 ESC.

Gee BEE

With the GeeBEE plans from another thread which uses the plantraco gear; I have made a larger version suited to the AR6400 with an AP05 BL motor set up.

This is a 3 ch, with under-cambered wings with dihedral. She is a little and would be better suited to a 2S set up. The build was going great until I had some issues with the paint eating the foam in certain areas - so its not as attractive as it should've been. I'll probably built a lighter, cleaner version after I test this one out this week at indoor session.

Here are some pics - and yes; I like bright colors lol

Not to be negative, but it's pretty apparent that won't fly very well.

The Wings need to match for camber, especially if you don't have ailerons to balance them.

It should make nice, banked right turns.

you mean cause the one wing looks more curved towards the fuse? (wing on screen left?) its because it broke on a maiden flight and has been glued back together and fixed since that pic.

oh, the right wing is broken. That makes more sense.

yes lol - I have since repaired.

due to painting damage - this has just become a tester of sorts - I am to build another version, that is lighter ect but will essentially look the same

Want to use this as a tester
