What brand to use to recover blades?
Hey i have some blades that the wood is in pretty good shape but a big piece of the covering came off. So i want to recover the blades.

Heat shrink covering... kinda hard to find these days. A quick search found this:

I tried flying upside down once... but I couldn't take the blood rushing to my head.

You can also check with Batteries Plus if you have one around, they should have several different sizes and maybe some neat colors, should be cheaper that reg heat shrink too.

I've covered my home-made blades with standard Monocote. This covering uses heat to shrink the covering as well as to activate the adhesive. It works well for me.Gerry Cullan,

I use Top Flight Monokote as well. Works great, lighter than shrink tubing, but harder to apply. You can also go with any color you want.

ok so i just used some monokote.

I think its too thin to work with easily. Even with good tension it wouldnt lay down smoothly. IDK maybe i just dont have the iron skills.

Seems like if the monokote were thicker it would be much easier. Also the stock material is thicker than monokote, thats for sure.

I'm going to go and check out the other brands at my LHS, and see if any are thicker, and test that out.

Use Monokote trim sheet. It comes in lots of colors. It is thicker than heat shrink Monokote and is sticky backed. It's easy to apply and holds up fairly well. You can get it at most hobby shops and it's only a couple of bucks. You can probably cover three sets of blades with one sheet.
The problem with heat shrink tubing is that when the blades produce lift, the covering lifts and the airfoil changes. This creates all kinds of problems, blade stall, tracking problems, etc.
Years ago we used the heat shrink tubes exclusively and never realized how bad that stuff was. The covering must be held with some sort of adhesive to prevent it from lifting.

I left a little of the stock covering at the root, removed the rest and covered with monocote trim sheets. The checkerboard looks really cool. With the symetrical blades it wont cover the curved tips however.

The curved blade tips can be painted to match the Monokote and then protected with CA or epoxy thinned with a little alcohol and painted on. I think the epoxy protects better, it stays more flexible.

i just used trimkote on one of my blades.......MUCH better than monokote, and prolly ultracote, and prolly econokote, since all of those are thinner and not stocky.

trimkote worked killer!!
i was so happy i went against my better judgement and flew outside while it was a little too windy....manged to put a nice ding in the new trimkote hahah

You would be amazed how durable a balsa blade is when soaked with CA. I have been building blades for a while and fly them bare with CA applied to the whole blade. My current set of wood blades has out lasted my previous set of carbons.

I don't paint them. Too much work for something that inevitably gets destroyed(if you are pushing the envelop). CA adds very little weight. Use the "thin" CA. Also a hint for the newbies, keep the blades a little loose in the grips for mild hovering, your blades will last quite a bit longer.

Typically they are supposed to be tight enough that the blade doesn't slip in the grip when the heli is held on it's side. If the blades aren't tight they can fold in flight. Doing lazy maneuvers and basic hovering there is low risk of blades folding with blades on the loose side. I fly(hovering and fff) with my blades fairly loose. I inadvertently flew into the mailbox post(lost orientation nose in) the other day and blades are still perfect. Stock blades with no CA and tightened down would have never survived.

If you want to recover your blades with something stronger then shrink-covering(monokote, SolarFilm.. etc) id recommend using 36mm heat shrink tubing.

http://www.srbatteries.com/hrdshrnk.htm

Its $1 a foot... and will make the blades look factory new.

just my .002cents.
