Making a 3S lipo DIY style

Dont miss out on good flying weather just cause you forgot the good battery at work.
The video is quite self explanatory.
McGyverism daily #1 (1 min 31 sec)

I reaally had to maiden my new f-22.
Problem was, all my 3s lipos were at work (flygakademien)
But instead of problems I see solutions
Having a lot of 1S 500mAh batteries for my micro helis, I just needed some connectors. After diving into the box with "misc cables with connectors on one end" I found them. Some soldering and woila! 3S-500mAh McGyver-style

(in the end I flew for 1,5 seconds and bellyflopped on takeoff... )

Probably happened because you attempted to use the word voila on the internet without already knowing how to spell it...

Thanks for the spelling correction.
Now I know why. (phew, dodged a bullet there, almost thought it was pilot error)
Is there any way to hack this "grammar to flight destabilisation system"?

If you are using FireFox, it has a built in spell check...

But kudos on the ingenuity on the 3S conversion.

All kidding aside;

control surfaces trimmed and moving the right direction?

wing cube loading acceptable?

prop on the right direction?

It was just a stupid pilot error.
Its been bad weather in sweden last 6 months, so I was very eager to fly. Checked everythin 3-4 times before launching.
Also, bellylanded, not flopped. Flopped would mean turning upside down right? (not sure about my english anymore...)
Didnt get enough speed/lift on takeoff. Not enough throttle. Should haver maxed it. Not used to pushers, mosly been flying tractors before.

CG is right, wing cube loading more than acceptable, prop in the right direction.

Need to learn the launching technique properly. I think the launch angle was not steep enough.
Next testflight tomorrow.

First off, your command of the English language is better then most who use it as their first language.

And yes, sounds like it stalled on take off. Could be that the non use of full throttle might have saved it from a snap roll, which is common on a stall, and having it crash. Maybe a little harder throw too would help.
