Ok so let’s say you had a model that was unstable in yaw and a rate gyro wasn’t doing enough for you what's next. You could go to a Heading Hold gyro... but then you'd have to fly the aircraft in yaw, or you could use sideslip feedback but for that you'd need an air data vane... After a little head scratching, some custom electronics, 3D printing, the tiniest bearings and a little luck here it is. As a prototype its fine but far too fragile for using for real, in terms of sca
The answer is very poorly, I forgot to engage the gyros prior to a test glide, and needless to say it fell to the floor like a brick. Unfortunately the white polystyrene prototype fuse snapped but not until after I'd got the yaw gains sorted and almost tuned the pitch. So a new fuselage is required and here is the replacement waiting for glue and 2mm upper and lower balsa skins which will be hand shaped after fixing. The two pieces of waste from the fuse longerons will be use
New blocks of code in OpenAero2 fix my issues, I don't even need to set throttle -ve travel to 0% on the Tx as I've hard coded that too to prevent a -ve airbrake demand, everything is now mixed in OA2.
I've been working with Openaero2 and a KK2.1 HC board on a fin less flying wing that's (intentionally) un-stable in pitch and yaw just to get to grips with PID control and the different stabilisation modes. I am however running into a minor hiccup that I can't seem to get past. I'm using split clamshell elevons as air-brakes with differential air-brake for yaw stabilisation, but I can’t stop the yaw gyro from pinching the two surfaces together, it's not a biggie but it could
