twisted wooden rotor blade

I was wondering if any one has ever recieved a twisted wooden rotor blade and if there is any way to straighten one once it is twisted? You all will probably say send it back but I got it with some stuff I got off of an e-bay deal. Anyway thanks in advance for looking at my post here.

Well Kent,

I reckon that when you buy cheap it does happen. I usually get more than I need and then if something is not right, I shrug and put it in my spares box. Sometimes a promise of a photo of the bad item will produce a replacement on Ebay, especially if you promise 5 stars on receipt of a replacment. I have had a few replacements that way - not many but around 90%. Usually it's more expensive to send the item back than to write it off. (At least at the prices I try to pay! Smile

)

Tom.

Hey tombo,
That's what I figured but just thought maybe some of you seasoned veterans had a really neat trick. I thank You for the reply.

I've never tried it with a rotor blade, and don't know the dimensions or type of wood with yours, but think how massive timbers are bent to fit a boat's hull.

Steam box.

If it's not laminated, try holding it over a boiling kettle spout (wear some thick gardening gloves) and steam it really hot (may take a while), then it should become soft enough to reshape.

Then let it cool in its new shape. Good as new.

Hope that helps.

Trouble is if it's plastic coated as mine usually are ....

But you could try either the steam method or just simple spraying down with mist water .... so wood is damp but not sopping wet ... then twist and jig .... leave to dry-out.

To be honest with them being only a few cents from HK etc. - the possibility of poor pitch due any residual twist would be a concern to me ... imagine the tracking error !!

If they are dirt cheap, get new, and use the twisted one as an exercise in improving your skill sets! Laughing

I got a T-34 from Santa and have almost re-built it... (new motors, new receiver, new blades, new grub screws, soldering new battery wires, tail rotor mod et al. All good fun. Very Happy

Thanks for all the replies. I know these are cheap and I guess so am I (lol) but what the heck it was worth a try. I did have it on mt Blade 400 before I noticed the pitch went the wrong way. Boy I thought I was really doing something wrong with the radio or something. With one blade going up and one down all the thing would do is make a lot of noise. Maybe I'll start a bad/broken parts wall or something like that.
Thanks all,
Kent P.
