Is there any chance you would be willing to post a version of these plans in .dxf or .dwg format? Your pdf defaults to a size bigger than the plotter I have access to at work. I'm more interested in the larger of the two versions and it would be much easier to plot from AutoCAD than trying to plot from the .pdf file.

Hi,

no problem, please send me your email address. I will convert it.

@Figure9: Nice! Which power setup do you plan to use?

Greetings, Roland

I have 2 BP21's with 8X6 props. For batteries, I'm not sure if I want to use lipos or NiMh. I think the NiMh would be more durable since there is a chance they might get wet. The raw airframe right now is about 450g. I have the motor sticks mounted in the pods, and all surfaces are hinged. My next task is to add the controls for the ailerons. Not sure if I should use 2 sperate servos, or just one in the middle of the wing. This has been a fun project, thanks for the plans.

Hi,

i use 2 lightweight servos for each aileron because i don't like torquerods. A big drawback is you need a powerful BEC to power 4 servos.

It is very nice to see what other people built with my plans. So thanks for the Photos!

Greetings, Roland

I'm sure this has been covered before, but can I run both BP21's with one Kontronic Smile 40-12-6 esc? I think the BEC is good for 2A, but I'm not sure it would work on a twin. Has anyone ever tried this with this ESC?

NO!
Each Brushless motor need its own Controller!
Trying to run one controller on two brushless will destroy the controller.
This has been well docutemented, Do a search here.

Almost done! Thanks for all the input. I'm using 2 ESC's and a ParkBec. Ran the motors this evening, and seemed to have plenty of thrust. 1250g RTF with 2 3s 2600 lipo's. Now all I need is some water, (warm water).

No, not yet. I still need to add the wing floats. I hope this weekend I'll have some time to go out to the lake.

Well, I guess you can call this a maiden flight. I went out to the side yard just to see if had enough power to pull through the grass. I powered it up and it started skipping on through the empty 1/2 acre lot next to us. Before I knew it, she was in the air. I made 2 passes then landed because my knees were shaking so bad. Just in that short flight I could tell this is going to be fun. I need to get to some water.

No, I didn't take anymore pictures, but here are a few pointers:
Cut the top half of the wing a little wider because of the curve of the wing profile.

For the wing spar, I used a carbon arrow shaft imbedded in 3 layers of fff.

On the trailing edge, I sanded the last 1.5" to half thickness, so that when you fold the wing over, the trailing edge will not be so thick.

Before you glue the wing together, glue in some extra material where the wing floats get mounted.

Good Luck
