My newest custom parts!

[concept1]

I finally got around to makeing another set of carbon Paddles for the Hurri. In the past I made paddles for every Heli I have owned ranging from 14-22g made from busted 600mm carbon blades. I have been waiting to find a set of busted 550 carbons since all I had was a set of 620's and I really wanted a narrower cord and a lighter paddle. But I decided i could wait no longer so I made a set out of what I had, they came out to be 17g so about the same as the stock paddles but they are have a thicker airfoil and are more aggressive do to where the flybar goes into the paddle. I made a jig years ago for the "50" sized paddles i was going to make a smaller jig for the 550 blades but i just made another 50 sized set to try. once again they came out near perfect and fly so much better! I went back to the stock flybar lenght and performance could not possibly be better, rolls are so fast, flips can be scarey if you are in FFF and pull back. i don't recall the dimensions I used, I made this jig about 4 years ago and I have made probably 30+ sets of them over the years for myself and friends.
I was suprized to find I can do rolls and flips with much less bogging, then with the longer Raptor flybar and stock paddles, I assume it might be do to the efficiency of the thicker airfoil??
Has anyone tried a set of Carbon V paddles? mine are very similiar

Really nice - good job.

Nice job! Do you leave the ends open foam, or do you cap them off somehow?

I use a aluminum cable ends from my local hardware store for my inserts, they are 5 cents each, I drill and tap them for the flybar and then epoxy them inplace, screw on the flybar and square them up, once dry I remove the flybar and insert 3mm bolts to the threads and clear out 1/8 inch of the foam on the flybar end, and fill with epoxy (I add one quick spray of flat black spray paint into the epoxy before I mix it) this gives it a carbon grey color, fill the end with epoxy, and when dry, flip over and do the out bound end, but I remove just a tad of the material to keep them light. then balance by removing (sanding) extra epoxy from the heavy paddle. suprizingly most of them come out with needing barley any weight modifying. I found the trick is you need to start with 2 of the same carbon blades and take one paddle from the same spot of each blade. if you take 2 paddles from 1 blade chances are you will have a problem balancing them. over all it takes about 10-15 minutes of work time to build a set not including drying time. also if you try this put car was on your flybar and bolt threads so the epoxy doesn't stick then you end up with nice threads in your epoxy you can use loctite or CA to hold them on,

Cool Man nice job

So you say that with the Stock Hurry flybar length you get really good flip and rolls but you didnt mention the stability in the hover?

Is the stability still preserved with your new paddles

Also

How about using the Blade tips when you make a set of paddles?

wouldnt this mean you would only have to close up one end of the paddle and you would have a nice profile on the other end?

Cheers

using the blade tips would be way too heavy! their is lead weight in the tips. althought I did make a set for a guy who wanted a set of 30-35g paddles for stability.

using the carbons, generally you get a more stable flight yet you also end up with quicker cyclic.
i started making these when I got my first Raptor 50, I hated it. it was quick but flew like crap, it pitched up in FFF, and it was real twitchy, my previous heli was a Centruy falcon which flew like it was on rails, but cylic responce was a bit slower then the Raptor. going with the carbon paddles I could get such a smooth flying Raptor yet it would roll like nothing you have ever seen. I played with the positioning of the flybar in the paddles , size and weights, I made about 5 different styles till I settled on this Jig.
years ago i could have told you more but I have forgotten the theories by now, but I know the thicker airfoil helps on the stability, and the position of the flybar gives it a much quicker responce, the further back in the paddle the quicker/ more unstable the paddle, too far back and you get a very unstable and you also will bogg down too much.
