Yeah they are nuts. I am trying to think about what i can use them for in the future. Heres a question for some one.
If one cell can do 30 amps, does connecting 2 in series or parallel double it to 60 amps? I am guessing that double the voltage does not but doubling the AH does but not sure.

about $8 for 230g of weight, but yeah i hate dead weight. 6800mah would be one long flight lol

thanks wayne, not going to be a problem with just 4 servos and an rx on this project but would be fun to build my own pack for a bigger plane in the future.

Look out for burning the top of your mouth. I hate it when that happens with those hours and hours of thermal flying (sun screen doesn't taste good)

glued the tail mount into position - the wings are pulled out of the rotor to sit on blocks to ensure we are level.

but wait there's more!
So all in all my expectations were pretty accurate - the AUW without battery, Rx, and CG balancing is 670g - the AUW balanced on the wing rod is 860g - my target was to be about 900g (like most of my ships) - the tail being 3D printed is a factor in this design as it is undoubtably heavier than a FG or CF tail - I think the true balance point was forward of the wing rod, so I think there is a bit of wiggle room to be under 860g - with a couple of lithium Ion 18650s there will not be too much lead to add at the front.

@thenated0g - have you toyed with reversing your throttle stick (main setup) - up is off and down is braking (pull for crow) - the guys I fly with all do it that way so I am interested when I see it like yours?

I strongly recommend that the Crow function mimic the action you normally have for throttle. That is down is slow (full crow), up is fast (clean TE). With a plank you need to have elevator comp and it needs to be adjustable in flight (on a pot). Mix this up comp in the ailerons only
Do you have any data on how to set up the surfaces on this plank?
My limited experience with flapped planks is that the flaps, in the begining, act like a strong down elevator input. At about the 50° point this starts to soften. At 90° I can often take out 30% to 50% of the up I added earlier in the flap movement (Flap is stalled and mainly just adding drag).

If you ever add power to your gliders, with the funny thing up front,
it would make sense to have the throttle the way to describe. Down for stop, up for go. You could then have throttle, for your motor, in the upper 50% and crow on the lower 50%. Even if we only have a 2 channel wing we still put the flapperons/soilerons on the left stick (down=stop, up=go)

Yeah I definitely hear what you guys are saying. I think what it comes down to as far as the stick direction is what makes sense to you. For me flying and having it up during normal flight just seems really weird and I would have to like think about it all the time. I don't think of the left stick is fast or slow I think of it as engaging crow more or less so that's why I have it in the down position normal.
And as far as @Konrad comment about how it's working I am totally sure that I have not set it up correctly and I probably should have said this is my first attempt and a long process of figuring out how to get crow working on this thing. And so I'm probably going to use the other two dials I have up on the shoulders of my controller so that maybe I can adjust the individual parts of Crow but this is definitely going to be a get way up high slowly add crow and see what happens and probably not even use it to land until I've tested it a bunch.
