Radix Blades and 450 Pro

[Britflyer]

Anybody using Radix blades on there 450 Pro?

I had a pretty big smash with my 450 Pro (Rx failure/servo failure I think). Well after replacing the Rx, 3 new servos, headblock, main blade grips, mainblades, most of the shafts, plus other stuff I got it ready to fly again.

First flight back and the machine is vibrating badly, almost unflyable!

After replacing so many bits I was abit miffed that the repair bill was getting bigger! Tried replacing the tail shaft and tail grips as they didn't appear damaged in the original crash.

No improvement! So £200 in to fixing the machine and it is still vibrating like a good'un!

I decided to try a different set of blades. Stuck a set of Torsions on and the machine is as smooth as silk! Put the Radix back on and it was vibrating again!

The only thing I noticed was that the Radix are quite loose in the Grips, but not that loose that you need a spacer.

Anyone else had similar? I am going to take the blades to work to weigh them for balance.

Abit of a shock that the blades are the culprit as I've had quite a few sets of Radix over the years with no issues. I got the Radix 2nd hand but looked in good condition.

*** Edit - Problem found - Looks like the used set I bought on the BMFA were an unmatched set of blades.*****

They may not be a matched pair is all I can think of.

May be the blades are not a pair of blades !
Have you used them before the crash?

[Geek]

sorry beet to it

As quoted twice above, I think someone has made a pair to sell on.

Used loads of Radix in my time and never had a problem.

If you don't have a blade balancer, might be worth doing Finless Bob's balancing method to see just how far out of whack they are, then revert back to whomsoever sold them to you with the results?

Of course, if you find them to be bang on, you need to look for another problem?

Yeah that is pretty much the conclusion I came too also!

For Sale: 1 set used Radix Blades - unmatched set - Perfect paint stirrers! :-D

Where did you buy them from Paul?

Not had a prob on my 450pro with the radix...sounds like you have 2 left hand blades

A guy off the BMFA.

Well I've checked the balance along the blade and it took 3 1/2 turns of electrical insulation tape to balance them up equal. Now I need to check the individual weight.

Certainly looks like a mixed set sold as a matched set.

Oh well nevermind, I'm more happy I know what the problem is than the annoyance of the cost of the blades!
