New to rcplane and new to forum also. Actually this is my first post. Was just looking at forum (lots of info hear) this morning and ran across your video. Neat video!! I have been reading about FPV flights and watching videos on youtube and vimo. Would like to try it myself sometime in future. Seems so complicated thow.

Must say i need to get more flight time before attempting FPV. I have a hawksky that i fly out in pasture behind my house. Trying to teach myself how to fly. Have crashed several times and made repairs so plane is still working.

Anyway great video and have a great day.

Nice job Mark. Tell a little about your glider, any pictures? What is the FPV equipment you used. Great video!

Sure, I am using a sony ccd camera 650tvl , 10mw video transmitter with a calibrated dipole. The receiver is a lawmate 2.4 rx with a 20db high gain patch. It's sitting on a tripod with an antenna tracking system (the antenna follows the model as it flies).

The glider is my own design, I called it Kondor, it's got a very wide chord 7032 airfoil, 180cm ws.

Glide ratio can be as good as 15:1 depending on wind condition, and wing loading.

Here are a few pics of the planes as built by some fellow modelers..

Nice set up...very good video and tele data. It dosnt look so over crowed with info on your headsup. I like the platform too..looks like a very stable plane. Thanks for sharing the info. One of the better setups Ive seen!

Thank you for the nice words, the platform is very stable indeed, it's got a little pendulum effect like most polihedral wings, but this allows the OSD unit to pilot the plane back home in the event of loss of ppm stream from the receiver, without the added cost and complexity of a IMU .

Sometimes the simple and easy platforms with inherent stability are the best bet. The rudder or ailerons don't have the authority to roll the plane upside down, so it will right itself up no matter what happens from the outside (wind, interference etc).

In the summer once you are above say 2000feet, you can catch thermals for hours in a row, and stay up without using the motor.

Overall I am satisfied with the Kondor, and other pilots are finding it to be a great beginner fpv ship, they say it flies itself, it's too easy, in fact once you are up there, you can fly it with trims alone, and that leaves a lot of time to look at the scenery.

I take it your not getting much interference where you fly..and what kind of range are you getting ? The 20db must reach out there pretty good!

Well with the 10mw tx 5km, but if I use a 1000mw tx I can go 50km.

Interference is not a problem here...
