Queen Bee FPV platform
 
7 Attachment(s)
I just completed a queen bee that I plan to use for FPV flying. Here is my current setup

Queen Bee EPP 100" wing
Hacker b50 LMR motor
Jeti 110 opto ESC
Thunder power ProLite 3s6000

Black Widow 1W 2.4Ghz transmitter
Cheap CCD camera (for now)
HS-81 for Pan functions
Servo stretcher for the pan function
Eagle Tree OSD Pro
E-Logger data collection
GPS module
Berg reciever
4 standard servos
Eflight BEC to power the radio
uBec to power the camera and transmitter
Eflight delta wing mixer (so I can use the RTH functions of the OSD Pro)

AUW is 6pounds 3oz

I am using a patch on the receiver and I have a L-com 6dbi Whip on the transmitter

only question I have is can anyone think of any reason I should not use the 6dbi whip for the Tx?

Wow, that is one intense flying wing! How do you launch it? I look forward to seeing how it does.

#3 downeym Jun 06, 2009 09:44 PM

hand launch! its still only 6 pounds and at 10oz/sq ft it should still be a fairly floaty airplane!

That's quite the ship going on there.

Put in a more FPV friendly receiver. The Berg is not that.

what would you recommend for a JR shift tx?

I figured that if I had issues I would go ahead and put in a UHF system.

I just maidened it and the pane flies quite well. As you predicted I have severe range issues, both with my video and the Berg...

I was expecting much more from my video tx... I wonder if it just does not not like this 6db whip on it...

I need to try it again with the 3db stock antenna...

I would get that 2.4gig transmitter further out on the wing to get it clear of the other electronics and put Ferrite rings on everything they really help. I would also get the GPS reciever as far away from the transmitter as possible. You have a ton of room on that bird use it to space everything out.
I have a Maxi Swift 52" flying wing and it is awesome for FPV, it is very stable and I can do loops and rolls like crazy with it. Good luck with it.

Very cool Mike, hope to see it in person soon!

Nice Job Mike!
It all looks like it went together fine and the flight was way cool.
I can't wait to see more!
Bring it by the shop some time for a look see.

I flew it again today at lunchtime, but I had a small mishap. The folding prop didnt want to unfold on me and it wound up ripping the gearbox off my nice hacker motor!

No damage to the airplane... but I wound up low and slow and spun it in trying to get the prop unfolded...

no biggie, but im grounded until I get the motor fixed... :(

Hi Mike,

Sorry to hear about the motor :( I've got the same problem on my Maxi Swift. Going to purchase blockers on both ends to restrict the movement of the folding prop.

Now that the plane is grounded you've got some time to work on some of the more severe issues:

Get your VTx out to the wingtip!! No need for a 6dbi, use the stock 3dbi. Your VTx is almost next to the receiver and it blasts out 1W. No wonder you've got range issues :)

I use a 4 pole ethernet cable to run the wire out to the wingtips. It's twisted (= filtering) and shielded with aluminum foil and the ground wrapped around the twisted 4 poles. Check my videos in the "Show us your videos" for the range I'm getting. As your wing can handle the additional weight, I'd even recommend using separate cinch wires for audio and video.

Run the receiver antenna out the other end, you've got so much wingspan so use it!

#15 downeym Jun 09, 2009 06:40 AM

Actually, the Tx is already 8 inches away from the receiver and the receiver antenna does go in the opposite direction towards the wingtip. I assumed that 8 inches would be plenty of separation, but you think that is not enough?
