Blade balancing question

[wildc4rd]

I am considering putting the 5 blade head on my 450/hughes500, but how do you go about getting (presumably) 5 balanced blades?

Thanks in advance.

Maybe the not the most foolproof method, but i would weigh them with some digital scales

With great difficulty!

Its much easier with an even number of blades. My 4-blader uses 2 pairs, so as long as I don't get them mixed up, it remains balanced!

I would suggest contacting your favoured blade supplier and letting them know what you need. They may be able to select three pairs from stock that are relatively closely matched. Then all you have to do is the final tweak! (And you'll have one spare!)

Make one blade the "master" and match all the others to that.

If you think balancing is a problem, wait till you have to track them.......!!!

speak to sports moto, i think they supply balanced blades for multi bladed heads

I'd get a batch of them and weight them as Darren said, then take the 5 which are the closest. Make one your "master", and CofG / balance the rest to that master.
Anybody else know a better way...........

You can get five blade sets for this purpose.. look at flying-hobby website or others doing heliartist parts.

The other option is to buy a bunch of cheap blades from hobbyking.. go for the cheap carbons rather than cheap GF which can be iffy on a 450.. Ive had a couple of pairs that just didn't fly right and were warped a touch.

I haven't tried it with blades.. but if they float then the easy way to weight them is to drop them all in a spaghetti jar and see how high they float vertically relative to each other.. that's the quickest way of sorting a bunch into closet match.

using a balance find the heavyist blade.... set that one on one side and then add tape to all the others until they balance with the heavy one...
