The goal of the project is free flight, so why mess around with motors. Well Simplicity. keep everything simple... simple... i hope.. simple.. 

I could either keep flying a two part system. Drop drone, drop plane, bridge, building, paraglider.... 

Or.. just fly up.. and test things with the throttle off. So.. 1 system it is.. can we keep it simple? 

can we share it in a way that it is simple for others?? ugh... we will see. 

what is the right thing to use... a large prop!!!! pusher... yea.. that is.. but why am I using EDF.... 

EDF are more power hungry and less efficient.

Why? 

For Simplicity.

For Safety.

The goal is that anyone could handle, launch and recover. 

In the end I needed to increase loading for the wings to work anyway, so extra batteries was not an issue. 

I'm using 2 - 3S 1500mAh batteries. Sometimes I plug them in together for long flight times, other times just one at a time. 

The original model I tested did have a pusher. It worked great. It also chopped lines... at least once. 

I have tried at least 3 sizes from 55mm to over 80mm. The large ones are loud and power hungry. 

Small ones are sorta not super efficient, but do the job. So what is the thrust vector?! Right now its perpendicular to "vertical" along the X axis. 

I have tried models pitching it down up to 10 degrees. It also requires finding the sweet spot of thrust, to moment.. to climb efficiently. 

Well Id like to adjust it from where it is.. Mainly because it pitches back the system, and if the loading is not enough a stall will occur. To take care of this I add a bit of speed system just as I get off the ground. 

I took it out today to test fly and get re-familiar with the unit so I can write these logs better. 

To add to the fun. Bob was flying. He landed so perfectly. no flipping. Full brakes. Flare to ready to fly again. Congrats Bob.. well done.
