I thought I would get creative on my canopy and share a pic with you! This is fashioned after the nose of an A10 Warthog. The Gatling gun is paper and the barrels are toothpicks. The blades are Wal-Mart yard sticks that I wiped with latex red and covered with satin polyurethane, they are 10g each. The tail boom is brass tubing. It doesn't shatter like carbon fiber and bends back after a strike. I wrap masking tape around both ends which makes for an easy R&R.

Enjoy!

Looks good, How do the yard stick blades you made fly??

Just to give you an idea of my level of flight experience, I've learned to hover and move around in the garage and have had a couple flights out in the back yard, still tail-in and was using the plastic blades. I'm getting better and don't hit things as much as I used to. The plastic blades (PB) have been tortured, but they are too flexible and I've replaced too many carbon fiber booms. All you have to do is land really hard and the PB flexes so much it will hit the boom. That's why I use brass tubing now. It is a little heavier, but not enough to affect the performace using NiMh batteries. At least for me!

One other thing I noticed about the performance of the PB, they affect control because of the flexing. The CP is a lot slower to respond. With PSB or YSB my flying is a lot better. I have more positive control!

I made a few sets of paint stick blades (PSB) and they worked really well. Better than the plastic ones, although the plastic ones will take a lot more abuse. Then I made a set of yard stick blades(YSB) and they work really well also. I like the YSB a little better than the PSB only because the stick is thicker than the PBS sticks and they fit the blade holders exactly, The PSB sticks are thinner and have to be shimmed to fit the holders. The Wal-Mart sticks were $.50 a piece and I can get 3 9.5" blades from each one. I used a PB for a pattern.

Chow!

Wow,

66c for a pair of blades, how do you profile them for equal lift?

Once I have the stick cut to length, the holder end shaped and the bolt holes drilled, I will draw a leading edge line 1/4" behind the leading edge and a trailing edge line 3/8" behind that. I will file from the leading edge line to the bottom of the leading edge of the stick. Then I will file from the trailing edge line to the bottom of the trailing edge of the stick. Then round off the top of the blade from the leading edge line to the trailing edge line, taking more material off toward the leading edge.

During this whole process I am eyeballing and making sure that I am removing material equally. I have had no problem adjusting the track and I've made a dozen sets of blades so far.

The only problem I've had was getting in a hurry and putting the leading edge on the wrong side of the stick (DUH!). They won't work too well on a CCW rotating bird so I just modified them to work on CW rotation. I filed what was the holder end and tapered the trailing edge back about 1.5". They look a little funny. They are hanging up drying (polyurethane)right now. It will be interesting to see how well they work.

Hey at this price experimentation is fun!

I hope this all makes sense!

I like the way you think...keep it cheap so the crashes don't hurt as much.

Here's the link to an article that got me started making my own blades. This is for paint stick blades made from FREE paint sticks that you get from the hardware store.

FREE! Did I say FREE!

The only way it gets cheaper is if you can get somone to bring them to you!

Ok,I went to Walmart and look for the wood yardstick and the
ones they had were to thick and I don't have a plainer so that
will have to wait till I can check out a couple craft stores
my wife goes too! Not being discoraged I went to the Depot
and got some paint stix, It took me about an hour to make them
and the biggest time issue was balancing! I don't have a gram
scale so it was kind of a guessing game as the stix weighed .6 oz
on a mail machine scale before and .4 oz afer with grips! Well
I must say I'm impressed with how well they fly and track! Due
to the fact they are about 1/4" narrower it just takes a little
more collective to fly like the flat bottom woodies

bbeverlie,

Too bad Wally World didn't have the sticks. I don't remember where in the store I found them. I bought a dozen or so a couple years ago for another project.

Glad you had luck with the paint sticks. Mine have worked really well.

Have Fun!
