I put a video together and thought I'd share it here, footage was taken at Stow Maries, credits to LMA members Alan Bithrey, Old man Redshaw, Ant and Tony Hill and Chris Poyser.

Superb Matt.. ...I would love to set one up just as you have done, is it a homemade movable mount or purchased?

Thanks for sharing,

Frank

Really professional job---great music to suit as well

Thanks Frank and Dave,

The pan tilt unit is homemade by Alan, I'll prompt him to post some info if you like. It has it's own separate radio system whereby the camera operator can see on a screen or goggles, a live view and scan round looking for foe. I was just flying taking him for a ride!

Currently Alan is developing the unit to use brushless motors for the actuation to hopefully make it all smoother (currently using modded servo's).

We designed the mount to be easily removable in my Pup, just four discreet bolts to fit, battery/rx and Vtx.

The chase shots were flown FPV with a Ritewing Z11 wing, you can see a snip of it in the vid.

Mat, first class job, well done to all involved. I have now put it on the featured video on the LMA's website front page. We could do with more of this sort of thing.

Many thanks Matt, tis superb....can't stop watchin it....... Any info on the mount would be appreciated.....I'm gonna rig one up to my Dauntless..

Thanks

Frank

I've been playing around with pan and tilt mount camera mounts, down linking and video recording for aerial videos for many years. I think my first experiments were around 1999-2000. Here is an earlier mount designed for a standard analogue video camera.



This the current version, it's the 4th or 5th I've built (I've lost count!) and the first designed for a trusty GoPro.

The basis for all my mounts to date is a large diameter, small ball, ball race in an ali mounting. Driven by a modification of a 360 sail winch. The modification being to replace the original servo amp with a better one for improved repeatability. Unfortunately, the new one won't fit in the case so it lives outside!



The tilt mount drive is a modified 148. The modification being to provide a second bearing, the easiest and most accurate way of achieving this being to use the main bearing from another 148. So, the victim was mutilated so that the top could replace the standard case bottom to provide a "double ender"





This enables two "tops" to be mounted on one body ...





The camera mount was fabricated from steel sheet



and when assembled looks like



so the finished thing looks like



The idea is that the system is self contained and can be moved from model to model. The photograph above shows a seat shaped mount although this has now been replaced by four captive nuts discretely mounted directly in the fus into which the four pillars are screwed.

When installed it looks something like



The next development will be a complete redesign to use brushless gimball motors for smoother operation, particularly for the tilt (the existing version really needs some chunky counter balance weights as a GoPro cantilevered off of a 148 is asking rather a lot!). I'm at the experimenting stage at the moment and really need to get down to the engineering now to produce a perfectly balanced gimbal in order to make some progress.

Please may I join in the praise. 1/3 scale models plus GoPro video is a winning combination.

Many thanks Alan for the in-depth guide, appreciated.... ingenuity at its finest.......... .

Excellent video. Well done chaps.

Well what can you say, absolutely brilliant.

Ace Video Matt.

and for all those that did, or even did not see the program on bbc2 last friday the 14 march, the footage in the middle section illustrating the story of the air war, was us too!! shot on same day by BBC camera team as well as Alan and the FPV flyers,

cheers all for an ace day and a half!!

Bloomin' beautiful film! Lovely Matt! Great work to all you guys involved.
