Hi guys!

Today I finally took some time to test HK Alti logger (actually it is Altitude permit logger) in role of ordinary alti logger.

And what a day! I manage to use thermals and soar my Marabu so high, that I starts to feel uncomfortable (bad visibility..moisted air) so I drop flaps and sprial nose down to "safer" height. Of course I was trying to thermal on that low height and was going up. As dinner was served on the table, and I was also impatient to see what will show the Alti logger on the computer, I landed.

This is the log:


Legend: red line=power on, yellow line=motor off, green line=temperature

Before a peak height, I have 2 thermals with average 1,6 m/s climbing.

Not bad for a "box" as Marabu is!

I build 2 axis brushless gimbal (HobbyKing Martinez clone electronic) and install it on the Marabu wing at wing strut joint. It needs some tinkering, but even now I am pleased with a result.

Just casual flying above my village... (6 min 12 sec)

Beautiful, I am not a quad pilot, but I assume that you had to use a flight controller with pitch and roll outputs.

I use gimbal that is attached at strut joint with wing.
Gimbal is stabilized by Martinez controll board, that drive two brushless motors acutating camera pod.
The sensor board has option for attaching it into 3 slots, that allows camera to aim horizontal, 25° and 50°below horizont, without need of extra free channel on TX.




Here is a video, that show all three camera views and another, aiming away from the fuselage side along the semispan:

And this is a camera view towards the model:

When talking about Marabu, I am playing with idea to build it completely out of 3mm thick white poplar plywood, except airfoil nose and narrow leading edge planking will be made from balsa.

I already made test wing rib bay to check the assembly, weight, strength and rigidity. After having part in my hands, I made some corrections in the new plan. This version of Marabu will probably weight a bit more than "original", but will be piece of cake to assemble comparing with original one of this thread. It will be perfect as KIT complete.
