Spotlight Review

 
"Estes Pro Series II Super Big Bertha, Great Sport Flier"
champfluff
The Estes Super Big Bertha was brought back from the 90's and has been up powered from 24mm to 29mm. I have an older D-motor powered model, but the newer design is much better, with through tube fins, Pro Series motor retainer, shock cord and parachute. I'm modifying mine for a 2x29mm cluster and should be a real crowd pleaser. Laminating the fins are a must, only epoxy, no white glue, fore and aft thrust rings, JT-80's reinforcing the entire BT-80, easier and not as messy as glassing the tube, an ejection baffle, +9 additional feet of Kevlar, or braided nylon shock cord attached to the plywood centering ring, some nose weight and at over 1/2 a mile altitude, a GPS tracker.
