finally , everything was aligned for a great day of aero towing.
finished and tested the tow release mechanism mounted on the Sky Raiders chuck glider converted to RC.
prepared the twin Bixler 3 , now using APC 9x7.5 props , and installed the landing gear..

using 3S LiPo battery, measured a 40 A peak total current , i.e. 20A at full throttle on each motor , in static test.
10 pound test mono-filament line about 30 ft long.
A red ribbon , looped many times over , did the service of the parachute at the end of the tow line.
The tow release mechanism was home made, can be seen in detail in the video posted below.

of course had a lot of assistance, mainly from Sean and Vishwas.
With Sean we took care of proper CG placement and trimming.
Sean flew the glider and I flew the tow plane.
Vishwas was the ground camera boss.

here is the video:
