I actually just got all the balls in today....picked up my scale from the house...


Also for the weight of my "balls"....I've weighed each in turn and they all weigh 281g or 0.9oz each.

The wooden balls however have different weights...all being wood and wood weighs different...are all about 26g each. Some more, some less.

The Post-It doesn't weigh anything....

Also, here is a pic of the proposed ballast tube design...very basic, but you should be able to get the idea.

Weight efficiency forgotten, I really love the idea of balls Ken. Just thought I'd make that clear.

For the wooden balls you might consider drilling some holes through them to either further lighten them or to at least give them uniform weight if the difference is that great.

Additionally, you might want to add in or create a ramp/emergency exit in front of the tube for the case of an extreme landing. Not sure if it's even possible for the Genesis or not, but on my one severe landing my ballast rather rudely ejected my servo tray and destroyed my switch (The water it landed in destroyed the servo and Rx ). The 3M plane I have has the ballast exit above the tray though so in the case of extreme failure, the slugs will shoot out the canopy and not the tray. Anyways, just saying, and no real reason to listen to me either

Keep them build posts coming!

A ramp sounds like a great idea....I was going to fully epoxy the whole tube inside the fuse.

I may have to move my servo around to accommodate...or perhaps just build that into the tube itself....hmmmm...

LOL....

I really like the building part...almost more than flying. Keeps my mind and hands busy.

I'd love to get enough of a rep to build for others....some day.

Picked up one of these twisting switchjacks for charging/powering up the plane.

http://www.canuckengineering.com/new...s/switch-jacks

Also found these...if you want just the bare jacks...

http://www.minute-man.com/acatalog/O...202.html#a2160

Will post more pics of the switch install and the ballast tube when I get them.

If anyone wants to pitch in together to buy just the bare jacks....The minimum is $20...I'd be interested.

I started with 3/4" dowel and covered that with wax paper, then pushed that through the carbon Kevlar sock and pinching one end with a wire tie, I pulled the sock tight, twisting the other end and clamping it off with another wire tie.

I finally painted on the epoxy and stood the whole thing up to dry overnight.

Where exactly is the CG Calculated on the wing?

In one of Jordan's first post shows 91 mm, But where on the wing is that measured?

Wayne,

I must say it again, this ship is very nicely done for the money and I can only hope it flies as well as it looks. Although wanted the red on the bottom at first I think it looks better on top.

Thanks again for the excellent job of choosing such nice plane for a great price!

Hi

If anyone has some decent figures for crow setup I would appeciate it.

I'm having a hard time dialing in the crow (flaps down and ailerons up) setup as I still have massive nose up with nearly max down elevator.
All the throws are based on what is given at aloft webpage.

Suggestions will be appreciate.

Tokkie
