Well, the CG is the same, wether you hold the plane upright or inverted. Balancing inverted is a lot easier, as the CG then is below the balancing points. If you want to balance this model upright, it will want to tip over to either side, even when supported right at the CG. Just put a little mark on the wing about 2 cm behind 'halfway wingroot' and balancer her at that position.

Thanks Fotor. I have 3 of these 737's built and haven't flown one yet. Always have other things that get in my way. This time of the year here we have more of what we call Kona weather. That usually means light winds so time to give it a go. Been practicing with my WR 777. That ones pretty good.

[QUOTE=Ming;23419077]747-400 is a must do project.
If everyone can build the 747 so nice like you, I can save my budget of the tooling.
Can you share more information about your 747? HELLO MING the 747 is just a card model.

One window aft the emergency exit door with the plane inverted worked fine for me.

Thanks jurgen. That's assuming I placed the window sticker in the right spot. Took some measurements and going to start with 21.25 cm back from the front of the wing. Gotta get these guys in the air before the end of the year!. If not I'm going to get a for sale sign!. Took off from work the last 2 weeks of this year. Should have at least one nice day to fly................I hope.

You'd better start with the emergency exit window to make sure you get that one centered, then place the others. Now one window back is the CG.
Actually it doesn't seem to be that critical. On my first flight I measured the CG with the plane upright at the spot Spyro recommends but something went wrong and the CG was way forward. I had to pull the elevator pretty hard to the plane off the ground (check the video) and keep a certain pull throughout the flight. Then checking the CG with the plane inverted I had to move the battery 2" back to get it right. Now the plane flies level with the elevator trim at just 2 beeps up.
Good luck for good weather the coming weeks.

If my measurements are right that one window back would be right about 21.25 cm back from the front of the wing which is where others have said to balance it at. So I'm going with that. If I dont get at least one of these guys up and flying before years end they not letting me back into the club next year!

I was originally very scientific at first, but these days, before every flight, I truly do just pick it up, straight and level, gear down, using two fingers- one on either side of the fuselage, with each fingertip on the window aft of the emergency exit. If it stays roughly level, and does fall nose or tail down rapidly, you're close enough.

I have been so impressed following this thread for a long time and have been impressed with all the great vinyls. I am curious, who is designing all of these for y'all? Are they coming from Callie, B&E, or elsewhere?

Thanks Doug. Hoping to get at least one of my Aloha 737's flying very soon. Got 3 built and they are just sitting in the hanger. Actually on my pool table! Practicing at the field with my WR 777 for now.

All my decals are from Callie. Fast, reasonable and great work!
