Rocket #4 - HobbyLabs SR-71 Blackbird R/C Rocket Glider
- 33" High, 22" Wide
- 24 mm Motor Mount (E15-PW)
- 8 oz unloaded at liftoff; 12 oz with engine
I purchased this HobbyLabs SR-71 Blackbird on EBay for $122.50 before shipping and motors.
There wasnt much to do but glue on the fins, attach decals, and put the batteries
in. So the rocket was completely uncharted to me when I took it to Ocotillo
for it's first flight. I got it down from the first flight, but it crashed
pretty bad on the second one. We'll see if I can get it to fly again :)
I could recommend two things anyone should do before shooting this rocket
up. First, heed the warnings in the manual ... it is tricky to fly.
I was used to dyhedral (angled) wings on beginners r/c gliders.
This has flat wings and elevons, and so flies more like a real plane.
Specifically, it can easily get into spiral dives :(
Secondly, I'd really suggest painting the plane a different color on the
bottom and/or top so that you can see it. Black on black may be great
for spy planes, but from 600-700 ft, even with the NASA fin decals,
it's really easy to lose perspective about which way the plane is
turning. I crashed in a spiral dive, confused about the orientation
of the rocket (glider).
Here is the flight log for the SR71.
SR-71 Flight Log
||approx 600 ft
out of trim boost (spirals)
spiral dive, crash
SARA Club Launch
spent hours rebuilding and painting it|
boost to approx 600 ft
made a few controlled turns
lost control while flying left to right in front of me.
fell off the right wing
hit the ground at about a 45' angle
broke the nose cone, spine, etc
would have been a lot of work to fix it
fly-to-fix ratio is too high.
ripped out radio & servos for use in other project
The SR71 is dead! Long live the next rocket!
