Title: 15 tip weight?
Post by: Bob Reeves on March 22, 2011, 03:57:01 PM

What might be a good starting amount for tip weight in a 15 carrier. I understand it can vary depending on many things, just looking for a ball park starting place.

Thanks...

 Bob, try 1/2 oz, or two 10 penny nails if the wing is foam. That's what has worked for me.  the attached picture is of a plane I took to Brodak's last year but didn't fly because of some leg problems.

Bob,
I think it best to make a wing tip box. Keep adding weight until the plane begins to hinge or rock back and forth excessively during low speed.

As a result of quite a bit of experimentation and test flying, I ended up with 2 1/2 ounces on the "Sniper". Of course this is for prop hanging slow flight. I would permanently install at least 1 to 1.5 ounces, and also have a box for more, or at least be prepared to affix more to the outside of the model.

Bill, are "sniper" wing cores still available? Mike

Thanks for the info, didn't make the same mistake I did on the big FJ and build the tip weight box too small. This is the tip weight box in the FJ-4-15 with a 1 1/2 ounce hunk of lead dropped in. Plenty of room for whatever it takes  y1

Sorry to hijack the thread for a second, but the Sniper uses "Halflite" 1/2A combat cores from the Corehouse. If you contact Phil Cartier, I'll bet he can hook you up.

     Hi Bill, you are so right about 2-1/2oz for tip weight in a .15 carrier plane that you plan to hang. Although the lines are lighter, the wings are shorter so it seems to take more weight out there than you would think. Eric
