Anybody else scratch building tonight?

Looks great but the pilot lets it down he looks a be wooden.

You state the obvious! Better than nothing though.

Now I am confused how this Otter power pod is supposed to go, just been watching a video on you tube and the guy had the angle the same as on the Flight Test video.

ie looking down the motor is pointing to the left of the nose (assuming its a CCW prop in its normal configuration, reversed on the motor).
If it was a CW prop as opposed to a CCW, I could understand the logic the thrust angle would be to the left motor rotation is clock wise. But the Flite test video suggests its a std CCW prop so the thrust angle should be to the right ?
Anybody built one of these that can give me some insight ?

I would be straight back with a little down thrust

Yeah I remember hearing that on planes with the prop on the tail, zero side and zero down/up thrust is needed. It may be something similar with a nearly mid-mounted prop. I would suspect it might want a little up or down direction with a very high-mounted prop.

As far as the high prop. With a prop in the nose like normal, we give it a little down thrust. With the prop way up there it naturally gives force toward pitch-down. So it may be that you don't need any vertical angle. (Of course others will know better.)

@SquirrelTail - you forgot the (squirrl) tail too!!!

How long did it fly for?

I don't know about that particular one, but I've built a few high mounted pushers myself. I like to have them behind the CG and angled pretty far downward so that the center of force from the prop is directed just ahead of the CG. Seems like a motor that high and that straight would inherently cause the plane to nose down under power. Of course, this can be mitigated by programming in a bit of up elevator with the throttle if your transmitter can do that.

The tiny trainer is almost ready for its maiden tomorrow! The clevises I am using will still slide up and down on the pushrods if I apply enough force. Am I using them wrong? Can I just put in a drop of CA on the pushrod and clevis to hold it in place? Any tips for maiden are welcome, and wish me luck!
Edit: I still have no idea how and where to mount the battery, I couldn’t find it in the build vid.

It's very hard to see here but don't those clevises have screws in them pushing on the control rods? You could use a drop of adhesive if you need to, sure.

CA will be fine. You'll most likely be able to break it free if you need to anyway. The battery mounts under the powerpod. If you're nose heavy you'll have to shove it back farther in the fuselage

How did the flight go? Looks really strong!

Haven't flown it yet. Just woke up

We'll find out in a few hours

There are screws, but even when fully screwed in, I can force it to move. It might not be easy, but still enough that I might worry a bit while flying.
@whackflyer and @Monte.C thanks for the help!

Good luck, it looks like a fun, fast, throw in the back seat and go anywhere flier.
That reminds me that I never posted about my recently built strix nano goblin knockoff. I don’t like the look of the ft goblin, so I started fresh, and I tell ya, once I got the cg right it flies like a dream. Needs a rebuild though, it had a few accidents when I was still figuring out the cg 😎.

 

[OliverW]

I found out it was tail heavy. It hit perfectly flat and broke the wingspan in half. Back to the build table it goes

 

[OliverW]

It got a new livery though. Couldn't stand the blue tape

I think it needs a bigger motor! I think I might built one and stick a c pack motor in it!

No need. It flew. Moved like stink hehe. There's not much left of it though

 

[OliverW]

I was tearing it up. Full throttle passes out of dives, and lots of inverted. I used heavier foamboard and I really felt it. It got unstable when you stalled it, and I found that out of one of those dives

 

[Quinnyperks]

Going flying for the first time.

First time, really?
