My experience would certainly bear out that 55mm is indeed crazy tail heavy. If you standby, you will see what kind of luck I have on the remaiden when I move it substantially forward. Gotta reinforce the wing root joints first, though. Leaving today on a two week trip, so probably be a month before I get it out to the field again. There will definitely be video.

Great Iraqi_cowboy that sounds like a plan.
I have an SU-27, an F-5 and a Pitts monster 12 to maiden so I'll be plenty occupied...

it's 690TVL and the color is very nice once the IR filter is installed. I wiil install one in my Reaper before I fly it.

Wondering around my LHS, I came upon a master airscrew 11X7 pusher. Now I have my prop. Now to get this thing finished.

Martin - I did the same thing; happened to have an 11x7 pusher in my spares drawer and thought, cool, this will work out. But then I figured out that with a pusher prop you also have to have a pusher spinner, regardless of which end of the airplane it's mounted or which way the spinner is pointing. I, of course, did not have a pusher spinner and what I ended up doing was just using a tractor prop and a regular spinner. One of the best things about electric is you can make the motor turn whichever direction you want, so a pusher is not really ever necessary on a single engine aircraft. I didn't realize it either until I tried to mount the pusher.

Correct on that fact. I dont have a CR spinner yet. I may not use one. Undecided on that. But then I can get one here. http://www.maxxprod.com/mpi/mpi-291.html

Ok, this may be trivial, however, I'd like to get opinions anyway.
The included carbon rod is not exactly beefy considering the overall weight and span of this airframe. Carbon rods have a spline, one side that has more resistance to flexing. This particular rod flexes easily in the other direction and has a slight curvature. When installed, which way do you think the allowable flex should be? Up? To create more dihedral when loaded? (this way helps eliminate anhedral when on the gear) OR, down to resist the flex under load? (this position creates a lot of wing droop when on the gear). Hope that is understandable.

Hmm. I haven't noticed a spline on my rod, will have to check it out. But, given the choice, I'd definitely orient it such that it worked to minimize the dihedral. Mine had far too much when loaded.

Thanks iraqi_cowboy.
I agree after looking at the videos. I'm going to orient it to load against the spline to hold the wings down during flight.
The spline thing is a fishing rod builders trick when assembling an IM6 or IM7 high modulus graphite rod. You have to place the rod guides directly on the spline or the rod will twist from torque when under load.

I'm using a E-flight Power 32, with 3 blade 11X7 prop and a 60 Amp esc.
