Picked up a PU recently and have been having a lot of fun with it.

Thanks to all the previous contributors for their ideas and mods. Mine incorporates most of them. I have been flying it on a 4S set up which certainly gives it plenty of poop - alarmingly so sometimes .

One thing I noticed recently was that a couple of small cracks had appeared in the foam where the engine nacelle meets the fin. This was probably superficial, but was allowing the nacelle to move slightly so I just inserted a small wedge of light ply and she's rock solid now.

Great flying model.

Glad you are enjoying the plane KiwiKid. I like the panel line detail. That looks sharp!

Sorry about off-topic:
BMW, I tried to view your vid (Post 1650) but Youtube says it's private. Is that because I'm behind China's Great Firewall? I have to use a proxy to open YT at all... :-(

KpJones: I'm in Europe and now it is inaccessible to me too. It was visible for me before.
The long off-topic FPV discussion with different points of view may have caused different settings for this video. PM BMW to find out.

How is your ARF Polaris taking shape?

AK68, I have changed YouTube settings for certain videos based on the current angst over here regarding FPV/altitude, etc. I should edit my post.... On a brighter side, I just posted another Polaris video (3 Polaris Flights) to my channel, for anyone interested. It's a compilation of 3 flights, one going for some distance but running out of battery... Actually two battery related landings.

Cheers.

ak68, I'm set to take my maiden, but it's been raining for four days straight. Instead of chopping the rudder, I installed a piece of epoxied basswood at the end of the fuse. Most of my flights are probably going to be from water, so I plan to do a few fast water taxis to make sure everything's water-tight and that the dragger tracks straight. Got my Master 3-blade yesterday, shipped with a 2-blade. It's balanced and on the bird. Just got back from where my local Walmart used to be to see if they had some craft paint, I had hoped to paint the pontoons red and green for orientation, but they're gone. Not a major annoyance...

Just hurry up and wait.

BMW Thanks for sharing youtube channel and explanation. The style of some landings begs for a tough belly.

kpjones7: Don't worry about painting red and green for orientation. It all turns grey in the distance.
Better to have a distinct pattern build up with wide bands of light and dark tones. Top of wing different from bottom. Don't fly too far away. Don't fly between the sun and yourself.
Happy landings!

With currently 6 posts you did I don't have a clue about your flight experience. I did my first flight and maiden with my scratchbuild polaris and learned: Always collect ALL the pieces. Some practicing on a RC-flightsimulator pays off.

For the maiden: do a range check, check for inverted control surfaces before takeoff. Plan where and how to land before takeoff. Remove all trees. Fly high. It gives you time to recover. Keep the nose in the wind and don't do slow downwind turns. Oh well... Wish you succes!

Shaky legs and trembling thumb is normal for a maiden.

Yes, the Polaris Ultra is one tough plane. If you watch the vids on my channel I've landed on just about every type of surface, other than water -- which is ironic.

I have a couple extra belly pans, and cover those with shipping tape. I can take off from any surface other than tall grass, and land anywhere. The beauty of a belly-lander!

Haha, ak, thanks for the pointers! I did gas R/C when there wasn't a lot of tech going on back in the '70's. I crashed a lot of balsa planes back then. It's the new technology that's brought me back. Foamies? 2.4 GHz SS? I spent most of my meantime sailboat racing, but here in the "sleepy village" of Hangzhou, there's none of that going on.
