Having previously got my hotspot down to 7kg dry (to be able to fly at my local field), i discovered that even with a VT80, it could fly indefinately on idle power. Landing it became a problem as it was too slippy and the runway was too short. After a few mishaps with fast landings i decided to abandon the 7kg limit of our local site and fly elsewhere. This meant i could now add an airbrake, wheelbrakes and add redundancy in the power supply and beef up the turbine battery.
Having painted the fus, burying the airbrake outine cast into the surface, i was pleasd to find i could see the shape using a bright led torch from the inside. My brake uses a servo that latches by virtue of an inline linkage. I have also added a pair of magnets to grip the airbrake when fully shut (magnets close but not touching) to stop the digital servo "singing".
