It's about time for me to start carving but there's little information in the manual. I can get the "plan view" from the plan and I can shape the top and bottom to follow the curvatures of the wing. But I don't know what it should look like looking at it from the front or rear of the plane. It starts out as a triangle But I'm sure I have to change it to something else.

Does anyone have advice for me or hopefully pictures of how you did it??

Thanks

You don't have to do anything special. This is one of those really cool things that works like magic.

Just draw a line (Lengthwise) down the center of one of the two sides that meet at a 90 degree angle.

Draw a line lengthwise through the center of the last rib.

Now, glue the wingtip to the end rib keeping the lines even

Now just sand the block to the same shape as the wing with a sanding bar (You may want to shave some excess off with a knife first - and places where you dig too deep can be filled later)

Placing Duct Tape on the wing will protect the sheeting while you are doing most of the rough sanding. Remove the tape when you're sanding more tape than tip.

I think most people follow the plans and construct the tips so the upper surface matches the wing profile and the end is the 45 degree bevel. This is done by attaching the tip stock with a short side (adjacent to the right angle) to the tip rib.

I chose to make mine more conventional and attached the long side (opposite the 90) of the tip stock to the tip rib and shaping the tip like a conventional wing tip. I've got a picture of the (almost) finished result in [link=http://www.rcuniverse.com/forum/fb.asp?m=5661736]my build thread[/link] If you look through the entire thread, there are a number of pictures from other people showing wing tips that might also help...

Thanks Guys.

It sounds so straight forward I guess I'll go for it the obvious way. It's just that I can't quite picture the outcome but if you say so, that's good enought for me!!

I see what you're saying. Sounds more like what I did on my US 60. But, being the beginner that I am I have to stay with the plan as best I can. I have spent a lot of time reading your thread and have enjoyed it a bunch.

Thanks all,

Frank

Do it, you won't be disappointed, in fact, you'll be slightly amazed!

In hindsight, I'm kinda wishin' I'd have done mine that way too...

I did mine almost exactly the way MinnFlyer explained. And as he says, it does "work like magic". Was my first build, and it came out fine. The only thing I did different was that I used my palm sander with 150 grit to rough sand the tips. Now, I did try carving with a knife, and then hand sanding, but that seemed to take a lot of elbow grease. I DO NOT recommend that you use a palm sander unless you are used to it, because it can get away from you real quick, and then you will be filling in! And I used masking tape to protect the sheeting, again being careful.


Just realized there is a spell checker on here now. How nice

Just make sure you line the end of the block up pretty close to the leading edge of the wing. If you have too much sticking out the leading edge, then your aileron will stick out further than the trailing end of the block.

some people just make a hard wood doubler and leave the wingtips flat.i carved the one i built to shape close to it then glued it on and finished sanding,line Minn explained.

Thanks for all the advice, guys. I did it the way Mike (and others) suggested and, sure enough, out popped a pair of pretty decent wing tips. They'd been hiding in there all along. Separated by nearly 6 feet of wing it's hard to get them shaped identically but it's close enough.

I'm slightly amazed!!

As the saying goes. The way you carve an elephant from a block of wood is to get a block of wood and remove everything that doesn't look like an elephant.
