Pardon the terrible flying, and terribly flying airplane, and terrible camera work. Haha. This is a battery test rather than a flight demo

It was flying pretty bad, because it had low line tension. So I was just milking it through anything I did. After landing, I looked at the motor. It looked almost inset. So we made some shims out of a bottle cap. Immediately better. Haha. I turned the timer up also. Gotta see if i can safely get pattern flight times, well and actually fly the pattern through. So I'll properly trim the plane for flight and keep inching up the timer.

Nice video I always love a good flitestreak. Where did you mount your battery?

Between the motor and leading edge.

Why such a large battery for a Flite Streak?  There are many examples of success using a 4s/1600 on that size plane. 

That being said, where did you find a 190 gram 4s/2600 ???  That is light for that size battery!

Why such a large battery? Because mines lighter. Lol. Also, I'm using around 1800+ mah for a full time flight. I had a 4s 2200 on here before, but it's awkward. I've used 100c 4s 1500 from my race drones. Not enough flight time.

Dane, you might swap out that prop you are using for a 9x6e or 10x6e of some variety.  That 9x3.8e could be a big part of your thirsty battery useage. 

As an example, Pat Johnston uses a 10x6e and a 4s/1550 to fly patterns with his Shark 402.

I think you're 100 percent correct on that my friend. I had stuck this on there as, that's all I had. And haven't flown in a while and forgot what was on it. Plus these flitetest props are nasty, loud, inefficient little buggers.
I'm using the FM-01c (if I recall the model number correctly). So with this flat prop,  I have the little rpm adjustment maxed out. That's gotta be worth a milliamp or 2.

But hey, as a battery test,  I'm abusing it more than I need to and it's still hanging.  Now that the plane is groovy, I'll change props and post a pattern video or 2.

To answer your previous question about the size in mah... the cells I use, that I trust to handle the current our planes draw, only come in a 2600 or a 4200. The 4200 cell is physically larger,  but only 22g per cell heavier. However, I doubt anyone is clamoring for 4200mah packs. Lol

FoolThrottle Batteries.... and no. You won't be able to find them. I'm not ready to sell them. Yet.
