"M 14" giant 3D model
Cool, an electric 3D forum.
Here is a picture of one of my latest 3D planes.
Spans just under 90"
approx 1600 sq" wing area
10 lbs +- ready to fly

Oh, yea
Forgot the power system specs.

APC 24 X 12 E prop
77 3p opto speed control
20 HRSC 2600 NIMH cells

Hi, Henke
No, I don't
I haven't bought one of those nice watt meters yet so I'm not real sure.
According to my calculations though, figuring flight time-battery capacity..
I'm pulling about 20 amps at input required to hover, and max amperage in the low 50's.
Plane cruises around at 25% power and flies at a top speed of just under 60 mph. That's at full power in level flight.
Are you running the 24 X 12 on your setup?

[X(] 60 is fast! really cool!
I run the 24x12 too. thinking 8S is enough (~28 round cells) no need to go for more then 2:1 thrust weight ratio
how does it compare to Gary´s XL?

I do have a CG problem on the M 14 though, it's slightly nose heavy.
Also, I haven't pushed the M 14 through anything highG like blenders, parachutes, etc.. Im not sure about the structural integrity of the wings and would rather not find out what it takes to break them. So I have been flying it conservatively.
I hover it a lot, it does really good at the high alpha stuff. No wing rocking, and no flap mixing required.
Might be building a new set of wings for next year, so I can really see what it will do.
