My SYMA S022 Big Chinook is still going strong, many months after purchase.
It's still looking good, flying great, but a blade-strike or two has the rotors looking kinda sorry, and no doubt, not working as efficiently as they could.
Top and bottom, front and rear disks, they've all seen better days.
So rather than buy new (I'm cheap:)), let's see if we can renew helicopter blades for a 3-channel copter...
In the foreground is a scrap of plastic with 220grit wetordry sandpaper wrapped around it. I'm going to use it to sand out as much of the blade-strike damage as I can.
The idea is to remove the burrs, but not necessarily the dents or cuts, digs, etc., because raised burrs will cause the most drag, which we don't want.
Here at the sink, you see the simple process involved. I don't change the blades' shape, or attempt to sharpen the edge. I'm just lightly cleaning them up.
All eight blades doctored, and I went ahead and wet-sanded the idiot warnings off the upper blade sets.
Everybody back at their post.
And it flies all nice again now. It seems quieter- as the damage to the blades increased over time, I hadn't noticed it getting louder.
Not as good as new blades, but at $20 for the FOUR sets needed,www.rc-fever.com/syma-s02207-main-rotor-blade-b-p-11671.html they cost more than half as much as the whole copter does now. Since my old airframe seems to have plenty of life left in it, it makes sense to get the most out of the original parts.
I've said it before, I'll say it again: The Syma S022 Chinook may be the best 3-channel copter available, once all factors are taken into consideration.
