Well done video, stick with the front view. Your rear view was not bad though. Smooth flight. Is that a #16 camera?

I managed to brave the cold and get a few flights in with my newly transformed Popwing night flyer. It flew great and I had no trouble with orientation. It could always be better with more lights or different configurations but I'm happy with how it turned out.

Here is a video of the 3rd flight filmed with my hatcam. (watch in HD 1080p)

Glad you guys liked the video. It is my first time using my hatcam. I actually rigged up that hatcam 5 minutes before I went out to fly so I didn't know how well it would work. I can't wait to fly it again.

Well I'd just like to add my 2 cents to the mix on this one for any future builders of this wing. The build was quick but take your time with the motor mount. I utilized the stock location for the battery and removed foam. The plane CGs perfectly with the Power 400 Zoom motor and a 2000 - 2200 mah pack. I'm working on a solution to help alleviate the flex at the nose of the plane and am thinking some strategic use of tape and or more carbon fiber re-inforcements should help out.

In flight characteristics are sweet on this one and I only needed a few clicks of aileron trim and a few more on elevator. Not a blazing setup on 3s with the Power 400 Zoom but I'd guess it's in the 45mph range flat and level with my tired old packs. Overall it's very stable even at slow speeds .... which makes it easy to land too.

This one is a keeper and I'm hoping to add some FPV gear in the near future.

Don

PS: Thanks for all those who contributed info to this thread. It was a great helpin making the maiden a nice smooth success.

CG issue

Hi all. I just built the 900mm Popwing and want to see if the manual CG (200-212mm or about 8 inches) is correct. Even with a 1300 mAh battery it is tail heavy. Are people using bigger batteries or adding weight to the node or is the CG wrong in the manual?

I watched a build video on Youtube that said it balanced perfectly with with 1300 and a few posts up GP 125 is using a 2200 mAh which is much bigger than the manual suggests.

I built the ARF kit from Nitroplanes

Tape something flat to the battery to get the CG per the manual, tail heavy isn't good on a wing at all. I fly my Mini with two different sized batteries and the smaller one gets weight added. I use a flat lead weight with Velcro. Add the weight to the forward end of the battery to help reduce the amount of weight you will need.

I think my CG is right around the 210 - 215 location as mentioned in the manual using the Power Up 400 Zoom motor (approx 2oz) and a 3s 2200mah pack.

OK. Thanks. I just wanted to make sure the CG specified in the manual is in fact the right CG. Are you guys finding 200-212mm to be correct?

If it is, I think I'll stick with the 1300 and add some weight. I was thinking about adding a slug in the nose skid.

I tried a 2200 nanotech I had sitting around and that was too heavy. Plus, the compartment is not wide enough for the 2200 I have. If I make it wider, looks like I might punch through the leading edge.

This post has how i reenforced my nose section. If i did it again i would use bigger rod(probably 4mm). I cut the battery compartment tthru to the top and larger since taking that picture.

wires on bottom

One other question. Whats the deal with the motor wires loose on the bottom. That does not seem like the best design concept both for drag and whn landing. Are you guys cutting slots to rscess the motor (and battery wires for that matter) or just let them hang?
