Home made twin motor plane for HD video with Pan and Tilt.

Hello guys,

I've been super busy at work so this plane has taken forever to get off the ground but did the maiden flight recently and here is the video I created from them.

It's a big twin motor plane designed to carry up my heavy HD camera in the pan and tilt holder I created. I hope you like it!

Home made foam board twin motor RC FPV maiden flight (4 min 17 sec)

Paul, that is a great video. The plane jumped off the ground and the video is very clear. Way to go. Great build!

Thanks quailbird. Yes, it has no trouble getting airborne that for sure. I put the slo fly props on there because I didn't have two of the regular ones and they pull like crazy but I should probably switch them make it a bit easier on the power train.

Canada, it's a Sanyo HD2 but I'm looking to upgrade one of these days with one of the new cameras that keep appearing.

good stuff Paul , maybe a more ridgid wing will transmit those bumps and vibes to the cam......and you can get a servo slower from Hobby City

Paul can you do a walk around foto's of the plane

nice plane. It looks like you using low power on the take off, because there is no big vibrations, and no bad sound. Am I right ?

I'm joining in, we need details! Lovely quality video. The only thing I would have liked was servo slowers on the pan and tilt.
Cheers,

Thanks All.

Here are the specs as posted on the Vimeo page...
Specifications
Wing 72" x 10"
Body 57" x 6"
AUW 9 pounds
Two AXI 2820/12 motors
Two 12 x 6 slow fly props (I didn't have two regular props so I'll try them as I suspect it will enhance the twin sound a little)
Two Jeti 70 amp opto ESCs
I use two or three 3 cell 3200 mha Lipos (I have room for three but only have 5 batteries so I've been doing one flight with three for 8 minutes and another flight with two for 6 minutes leaving a good margin of power left)

Thanks Ian!

That's true, that might happen, and I do really like the flight characteristics of the highly chambered wing. I always think I can do better so it's tough to leave it alone. I flew this morning and I think the wing is calming down some and the video is smooth (but I'm watching on a smaller screen) so I won't go too radical for now. Besides that would be a lot more work (and expense unless I cannibalize the current wing)

This one is so easy to land smooth, I really like that part, but it does weigh a lot more so I have to be careful and can't fly from just anywhere.

Sure, I put some photos up for you.

Thanks,
Paul

It's the same as this one....

Big Breakthrough with HD Pan and Tilt! (6 min 58 sec)


I just moved it to a larger plane as it was a bit heavy for my existing one.

Yes, video downlink is how I frame the shots and fly the plane most of the time.

I use 900 Mhz because I use the spectrum 2.4 system for control.
