Hi Scale Pilots,
have had the following experiences. Perhaps one or the other already knows or takes it for granted.
Namely the following:
When starting up the heli, I sometimes had a slight shaking up to the nominal speed and then vibrations in flight. I don't tighten the rotor blades too much, just enough so that there is resistance.
Interestingly, the phenomenon wasn't always ๐คทโโ๏ธ.
In any case, I finally figured out that the blades were still too tight.
So the leaves couldn't align themselves 100% I'll say again, they were always nice and flexible, not fully slammed ๐
Tests have shown that the looser the better. But too loose is also not good as the blades could fold in during assembly or transport to launch site etc.
Michael Rรถsener and I then developed the "Blade BlockerV3" ๐ช
In combination with the Vario Scale head and M Blades, a simple component was created that serves as a stop. The leaves only have enough slack to align themselves. Pre-run or post-run depending on the blade type must be observed.
In the meantime I leave the leaves quite loose. No vibrations, shaking or anything else when starting up, as it should be๐
Everything was inconspicuous in the air, actually more than perfect๐
Michael also tested the BladeBlockerV3 on his Big Lama and was really excited๐๐
The BladeBlockerV3 is from the 3D printer. In the middle there is a thread for a screw to press out.
The assembly is easy, just push in ๐
Maybe one or the other has the same problem ๐๐
I'm from Austria and use the Google translator if the English doesn't fit ๐

I don't quite follow how it works. Does it basically behave like a spacer that prevents blade folding, but loose enough to allow lead/lag?
Yes exactly, the BladeBlockerV3 prevents the blades from collapsing, I have 1mm of play, so the blade can move a bit so that it can align itself. So you only need to screw the blades lightly and align them perfectly.
Thank you Andreas for this post. Question: what is the purpose of the wing nut and threaded post?
Andreas, do you have one that fits the head on a HeliClassics Mi-171? Do you know Matthias Strupf?
Hi Michael, unfortunately I don't know Matthias Stropf. Have the BladeBlockerV3 only for the Vario Scale head in combination with M Blades. The BladeBlockerV3 must be specially made for each helicopter, there are far too many rotor heads and rotor blades.
Hi Thomas, the BladeBlockerV3 are in the blade holder, to remove them gently I turn the screw in and thus push out the BladeBlockerV3.
Great solution! I assume it will only work if the end of the blade is somewhat square and not rounded?
Yes, exactly, the M Blades have a special point, most of the blades are round. Yes, I'm glad that it works so well
