LAUNCH! Schoolyard, June 28, 2011
Central Florida had big rain yesterday, the skies were still overcast. My launcher was set up by 8:00 a.m. before the winds came up.
Here's my carded downscale A-20 DEMON launched with an Estes A3-4t engine. Free plans are available, check the "Free PDF Plans" tab on the blog.
This one gets great altitude with a BT-20 based body. I would guess the altitude was around 400' with streamer recovery.
The Eric Truax carded SCAMP flew to 250' with an Estes A8-3 engine. The overcast sky made the engine flame look big. It recovered under a homemade 12" diameter garbage bag parachute.
This is a favorite in the fleet, bigger than most carded models. It's a full size BT-50 sized rocket. Enlarge the picture and you can see the nose cone is rolled in stepped segments.
My big launch of the day (for this small field anyway) was my Semroc CENTURION with an Estes B6-4.
In this small field, a B engine in a BT-20 based rocket would probably be lost. But, in this bigger demo bird it seems to be a good match. Altitude was 325'.
While the kit is supplied with two 12" parachutes, one was removed to keep drift to a minimum.
The FlisKits MMX HONEST JOHN with a Quest MicroMaxx engine. Clean straight flight with streamer recovery.
The 13mm Odd'l Rockets UP! CUP with an Estes A10-3t engine. A noisy wiggler with aerobrake recovery.
