Richard Unwin replied to Scott Ashcraft's discussion UAV Catapult Launcher"Hi I made one last year to launch my UVA and have had success launching a 60 size that weighs about 4 kg and has some power left which when I get back to it will be able to launch my bigger custom UVA. Total cost was about 300 with a bit of…"
Richard Unwin replied to Richard's discussion 2.4m DIY Twin boom for Aerial Photography, Video, GIS, Photogrammetry"Richard, looks good but you need a fair bit of power to launch the heavier plane. Awhile ago now I made a launcher that works quite well using a pulley system and a compressed air ram, if you want some details let me know and also have a look at…"
Di Ka commented on Richard Unwin's blog post My UAV build update"Thank you Yves,
An aluminium spacer would protect the cf from wearing around the hole and from crushing when ocertighting the screw. But still, If you put a 10 OD/8 ID alu spacer in the 12mm CF tube, there will be no space left for bothe the servo…"
Yves Gohy commented on Richard Unwin's blog post My UAV build update"It is a good idea for both tubes.
But we must put a spacer inside, to avoid crushing the tube."
Di Ka commented on Richard Unwin's blog post My UAV build update"Hi there
Could you share any idea on how to lock the 12mm CF tube inside the 14mm tube? I think that simply drilling a hole to allow a screw & nut, would make the two CF tubes wear around the hole PLUS you would have to make sure the screw…"

Richard Unwin replied to Richard's discussion 2.4m DIY Twin boom for Aerial Photography, Video, GIS, Photogrammetry"Richard, great photos, i think you should start mucking around with vacuum bagging, as it is surprising how much less resin (weight) is left in the finished product compared to hand applying resin. The most expensive thing is the vac pump, but if…"
Richard Unwin replied to Richard's discussion 2.4m DIY Twin boom for Aerial Photography, Video, GIS, Photogrammetry"Richard, i just weighed mine tail as previously pictured and it came out at 430 grams, with 3 servos and linkages, so yours is not too heavy yet:)

Richard Unwin commented on Jaan Kronberg's blog post norway trip and it's outcome"Great shots of norway, are you making a tourism commercial if not you should be. My only minor critisim is the speeding up of the shots upsets the grandeur of the scenes imho.

So I thought I would get some close up shots and higher res video to show some of the finer details of the launcher. Like most things in this hobby it didn't go to plan as when i went to take off the Esc and Motor smoked themselves, so no launch, and after borrowing a friends motor found that he uses…

Today I christened my new plane launcher with success. I have built this as I have found the properties where I want to fly from have little or no adequate takeoff areas since the fields are full of waist high grass or lots of rough ground. Landing is OK by slowing down and dropping into the long grass but takeoff has been hazardous, to say the…

OK, to explain, i finally got the autopilot sorted and installed in a test plane and all went according to plan, until the wing support failed on my manual flying back to land. what takes away the pain is that it wasn't in my full size plane, that I maidened last weekend successfully with 2 x 8…

warren, yes David at Bask Aerospace sent out a new complete autopilot and this one worked, I will ask him if he found a hardware issue with the first one as it would be good to know what was the fault it case it happens again.
