Blade covering

I came across Radical RC .com and noticed that they had a large range of heat shrink tube sold by the foot, that theyuse for making battery packs.I was wondering if any one had tried this material on rotor blades. It may be a little heavy?? Or has any one found other heat shrink that may be suitable. Unfortunately the Radical stuff is BLACK.

Chris,
Have you tried Shelve Lining Contact Paper. I've used this material on many Helicopter Rotor Blades with good results. An Autogyro Blade with it's thin trailing edge would require you strongly crease the paper at the TE before installation to insure there is no stress at that point. Other than that it should work well.

Chris, I Found this on the internet. Thought you might be interested. It deals with Heat Shrink of different colors and thickness. Look at the "FiniTUBE C" data sheet.

heat shrink for blades

Hi,
The stuff on the site shown is very thick for blade covers even the ultra thin
is 20 thou. before shrinking. It will add a lot of weight. You really want something under 1mil. even .5mil. hard to find in less than full rolls (900meters). What is the chord of your blades? I might be able to help.

Yes I know what you mean. Only after ordering the tube from HKING did I notice the weight was a bit over the top,and yes I have seen a lot of tube that would be suitable ,but only in bulk which is something we do not require.I am looking at tube that would be suitable to cover blades of 2 1/4"". Hope you may me able to help.

Well by the sound of it ,the 2'' may be OK for some of my 1 1/2'' blades but to small for the 2 1/4'' . Do you think that the 4'' would shrink down to 2 1/4?? and what colour is it.If it is suitable for my use then I am interested.

shrink film

The 4" film will shrink to 2" so it should be a good tight fit. I only carry clear film because minimums to order is nearly 10,000' and there are lots of colors. Fusion paint works well on heat shrink film. Where did you find small dia. shrink wrap on the net? Orders are almost always made to specs. I'm curious to see what's available.

The shrink wrap I, found was all out of China in bulk several colours and many diameters. Unfortunately the clear is no good for me , but I am sure it may be OK for others.
You are talking to the modellers who may have a use for your excess product.so this will be a good place to advertise the price you are willing to sell
I should think that some of the guys building the large blades on the PCA -2 may find a use for it.

Blade covering

I must be the only one who covers my blades with doped-on model aircraft lightweight tissue. Same for the rest of the aircraft. Too old to change my ways now! Have never used heat shrink plastics for anything!
