Anatomy of a 126 km Flight

Last month I detailed my plans and preparation for an attempt at a 100km flight in a blog here.

Well yesterday the weather was ideal and my preparations (nearly) complete so I went for it and achieved a flight distance of 126km in a time of 2 hr 46 min 40 sec.



I can't attach my log file here because it's too big. It's 15MB and there's a 7MB limit. Any ideas how I…

Anatomy of a 100km attempt

Posted on December 12, 2013 at 3:30am 73 Comments

I'd like to fly my plane 100km. Partly to earn the cool badge, but mostly to see if I can.

The airframe is a Bormatec Maja airframe which is made from EPP, has a wingspan of 2.2m and an empty weight of 2kg.

I've been tuning it over the last several months to get the best efficiency I can. I've…

hi moglos, sorry but I dont have it!

Hi Franco,

I have not been on the site for a while as all of our work is commercial but I do follow what everybody is doing on a regular basis.  Great job everyone you are doing amazing things with the tools that you have.  Although I am the owner of the company I am not the only one in control and the talk in the office is to stop discussing the work we are doing.  There is a lot of competition in this field which we believe is going to expand rapidly in the next few years and we don't want to sell the farm.  To others that have inquired about the software we are using, it is a beta software that is not yet released.  It is not owned by my company; we are simply the beta testers and to my knowledge the only users in North America.  As for the Maja I think I can give you some advice on the airframe.  It is a plane with excellent performance as a UAV platform in most conditions.  It is very stable and flies beautiful straight, flat lines collecting very usable photography. The Maja does have a terrible tendency to stall when banking with a tail wind above 20 kph .  The minimum throttle must be set high to avoid this problem; we keep ours at 50%.  Another problem with the plane is its fragility.  Landing in tall grass or brush can damage the soft foam by cutting into it.  We wish it were made of EPO (Bormatec please listen to us!).  The elevator, rudder, and ailerons are particularly sensitive to the grass shredding them. We have adjusted to this by adding carbon fiber to those surfaces and have since reduced the problem although those surfaces still tend to tear from the frame at the hinge.  Add some Beacon's Foam Tac glue (the best glue we have found on foam planes, bar none) at the hinge and it reduces the issue.  Any hard landing with either the tail or nose first will invariably result in damage.  In our testing we have literally broken three Maja completely in half and one into three pieces.  We have modified the plane by cutting the bottom of the plane in half (with a hot wire) and inserting two carbon fiber rods the full length of the plane on the left and right and then gluing (with Beacon's Foam Tac) the two pieces back together.  Hard landings are no longer an issue and we have not had a problem since, even if we smash into the ground.  The motor mount on the back is also an issue.  We have had the entire motor mount rudder assembly rip off twice while in flight probably due to our high AUW of 3.5 kg.  To fix the mount we cut the mount in half and insert two carbon fiber rods on the left and right, glue it back together and then mount the motor plate with two large nylon bolts directly into the carbon fiber rods.  For extra security we then use 1/2" Velcro straps to hold the entire rudder assembly to the body.  Those white plastic pins often break and are not sturdy enough for our uses.  As for the settings we started with the Conservation Drone's

http://conservationdrones.org/

settings and then did a few modifications as needed.  If you are going to fly with a high AUW ensure that you have a powerful enough motor, esc, prop combo and complete all the re-enforcements of the body or you will be in trouble.  The plane ALWAYS dips precariously close to the ground on launch so you will need a very high launch area.  We hand launch from a pad on top of our field truck and skim the ground on every take off.  I hope this information helps anyone out there and if you have any other questions please feel free to ask. 

John

Dear Moglos, 

I've just read Your 100km attempt. I was impressed by the research You did on motor prop confogs. My Maja is on the way from Germany, but I have not yet ordered any electric parts. Im not willing to attempt anything like You, just want to set up a system for FPV maybe later add a PS camera on the plane. Could You give me a good starting point for motor/prop setup: I would appreciate any help.

Thanks

-vince

Hi Moglos,

thanks for the fast reply, I was thinking about that motor too, good to know I wasn't that off with my concept. Im sending some good weather from Europe for your attempt, keep us posted :) Good luck!

My doesn't that Badge look nice.....Better than any other cheap 200Km badges around.....oh yeah there AREN'T any of those out there either !!  Great Job again. Wayne Garris is blowing a gasket over this one....
