Spotlight Review

 
"Good for Heavy Kits"
FinBurner (Brandonbacn@outlook.com)
This is a good first flight motor for heavy kits. I use it all of the time on my old Estes Skywinder. I've never experienced a failure of one of these motors. PROS: Good for test flights of heavy models. It keeps the recovery area small, great for parks. CONS: The delay is not long enough for light rockets and may result in early deployment of your recovery device (streamer or parachute).
