R/C rocket glider flying on longburn H-13 motor
 
4 Attachment(s)
This was a flight of my Aurora Clipper on the new Aerotech 29mm single use 8 3/8" long , 7.25 oz, 17 second burn H-13 motor. Loaded on the pad this 6' tall glider weighed 32 oz, Since I had to stand 300' away for launch due to pad setup I didn't want to angle away for the entire flight so in order to keep it in sight I flew in a corkscrew till burnout at 1200 feet. It has 4.2 oz propellent so the CG shift is pretty large, but it handled it just fine with up trim.

Very impressive!

Curious, do you use 'launch presets' on your transmitter, or 'flight modes' to vary control surface settings/rates between boost and glide modes?

In effect yes, but only for elevator trim, I don't modify rates. I'm using the flap elevator trim function to give me boost/glide elevator trim settings, in this case, neutral for boost and up for glide, you can do the same with flight modes using elevator as fmode so you can have different boost/glide trim settings for each mode....

Is that motor an end-burning Blue Thunder or Warp-9 propellant ?

End burning super thunder motor, with a slot at the nozzle for the spike off the pad to get it going, I think it's 10 lb, then a constant 3lb or so.
