I bought an upscale cone of the ZOOMBROOM by Rocketpad(called a "MEGA ZOOM BROOM"). It flys with 24mm motors. Launched it with a C11-3 and a D12-5-cool flights!
I had an original one back in the 70's but have no idea what ever became of it. When I got all mY old kits from my mom's house in the early 90's, I did not come accross it.
But the big one is fun!
