I really like the looks of that plane, is that your own design ? Where did you get the wings and fuse from ???

Hi Jett,

nice to hear from you, I really like also all your self-made planes and specially your exciting videos ! Unfortunately we don't have such a wide areas without buildings and streets here in Austria as in your neighborhood. So it is a bit difficult to fly around with goggles .

According to my project, as I mentioned before in my posts I just try to build a semiscale copy of the well known UAV Aerosonde (, see attached photo also. Aerosonde was the first UAV that flew over the atlantic ocean in 1998. As I'm a fan of double boom pushers I decided to build such a plane as an successor for my good old TwinStar II. Currently I'm collecting all the necessary stuff for the project.

The wings are from a full glass fibre sailplane that was lying around in my cellar since over ten years. The wingspan is 2,5 m (8' approx.), original Aerosonde is 2,9 m, and was manufactured in the Czech Republik as I remember.

The foam fuse on the picture is from a Partenavia/Funliner kit of a german manufacturer ( but in the meantime I found a guy in germany with a self-made plane with a glass fibre fuse similar to Aerosonde much better suitable for my project as the Partenavia fuse (see attached photo). He promised me to build a second fuse for me .

Upgrading from AP to FPV/RPV "Wide Body Super Kadet"

HiAll,I'm new to this form of flying and will be learning as much as I can this winter so by Spring I'll be prepared and try to avoid any suprises.I have been working on aerial video useing my scratch built "WBS Kadet".It's from Sig Kadet Senior plans and bashed to death The following changes were made in order to accomodate my ancient Sony Hi8(2lb. video camera):
wing span increased from 78" to 86"
stab&rudder control surfaces increased in size by 10% and aero-ballanced
Fus width increased from3.5" to 6.75"
Fus height from 4' to 7"
tail-dragger instead of trike (custom main gear from 6061 T6)
Ailerons and flaps/polyhedral wing/plug-in tip panels and bolt-on
Pull-Pull rudder
AXI 4130/20,CC 80A ESC,5s3p 6700 LIPO,20x13 APC-e blade
Camera:Aiptek 5100M pocket camcorder/512 meg SD card
I originally re-designed the Kadet to cary 3-4# of payload and replaced the 2# Sony Hi8 with the Aiptek cam Anyway,here's a few pics of the camera ship.I'm just now finishing my smaller dedicated camera ship and will post pics of it if there's any interest.Here's the specs on the new one:
Length over-all-50"
AXI 2826/10
AUW with Aiptek Pocket X-3#12oz.

would it be possible, with the lightest gear available to put a pan up/down/side to side camera *smallest one available with sound if possible* on a motorized paragliding figure? I'm building a back pack paraglider model with a 12 inch tall figure and using carbon fiber hollow tubes for the back pack frame to strap the figure in. The camera will be one of the smaller variety *color and sound if possible* I'm trying to keep weight down as the whole thing needs to come in at just under 2 lbs. I'm using a brushless 400 park motor from Eflite and a gearbox swinging a 8 inch three blade gws prop.

Additional info: Parawing is a 6 ft stunt kite converted to paragliding capability. *thunderfoil series* pack will run off a 3 cell lipo pack either behind or below the seat of the figure's motor pack. protective prop ring around prop to prevent lines from snarling in prop.

I don't have exact weights in front of me, but assuming you build your own tilt and pan out of 3/32 birch ply, using something like Hitec 55's you can probably get away for less than three ounces in video gear including the tilt and pan. Dunno about the mic. One came with my 200 mw tx, but not with my 50 mw. I've done fine with a 50 mw tx and it would probably keep your total weight closer to two ounces.

I got my 50 mw from BWAV. He no longer sells the cased ones and I suspect that when the uncased ones are gone that will be it for 50 mw.

As for range, I have been using a dual patch with a diversity rx on the ground and I get a strong signal as far away as I am comfortable flying my pico Tiger Moth by visual contact. I haven't been out of range with goggles, but that's because my spotter/safety pilot yells at me when he starts to have trouble seeing the plane. Never had a problem then either, on just 50 mw, and I was using a plain rx and 8 dBi patch then.

Hope this gets you off the ground.

Thanks Pete, and it sounds like you've got a nice setup. I'll have to figure out the rest myself. I have a design idea I'll draw out tonight and share with everyone here *might've already been done* but using the smallest servos available, I can make a very compact tilt/pan system that will sit just in front of the figure in his lap.

Hi Twin,

really nice plane , I love these foamies from MPX very much ! Just convert my FPV TwinStar II also to brushless and add a FS8 Co-Pilot for wing levelling.

Cheers, Erwin

I think FPV is the way of the future to come in rc flying. I've spent most of the winter reading about this. This is something that I'm will to spend and try.

Hi everybody, I'm new in the business.

I've just bought a X11 kit at RC-Tech and I'm gonna try my plane this week end.

Plane is my design. Has already flown and should be slow enough for a beginner in FPV !

Bonjour Paul

It`s glow engine or electric?

Hi VRflyer,

Like everybody else, I congratulate you for the fantastic work you've done
in the FPV field of knowledge !

My plane is electric.
Motor: Hyperion 2213/24
ESC: Titan
Wingspan: 1 meter
Weight: 768 gr

It may look mean but it has a high lift NACA 2414 airfoil so it can fly
with a reasonable speed.

I've equipped it with RC-Tech hardware because of the french legislation concerning radio transmission power: 10mw maximum for 2,4 Ghz...

I'll try the plane this week end if the weather is OK. I hope I will have the time to put on and off the goggles without loosing my plane out of sight.
This is the hard point I think... I'm a little bit nervous
