Hangar 11 kit of the X-15. This one has interlocking fin system and is the smaller 4" version H11 sells. It is designed for motor eject/single deploy; however I've modified for Dual Deploy.
Stratologger CF, Eggtimer WIFI switch & EggFinder, 1.9 & 1.5 BP for ~2-2.5k.
Fantastic straight boost and faint whistling on coast. Medium delay (for backup) was good as well as DD charges. Main came out, but got tangled and rocket came in a bit hot and landed a little hard on sod. No real damage and just some small paint fixes should do. Crowd loved it!
