Wood blades+ logo 400 @2400rpm= disaster!

[LaurenceGough]

They included wooden blades in a V-Bar Logo 400 kit?? Actually in the box? I doubt Mikado would include such low quality blades for a high quality heli... Maybe for the flybarred Logo 400, I wouldn't be surprised at all if this was the case.

[Janek]

Tom buys a Logo kit that includes a set of blades so he fits them(

Who included the wooden blades, the supplier (FastLads ?) or Mikado ?

Whoever it was, needs to be shot at dawn, because supplying wooden blades for a high performance electric heli is simple madness

Further to Janek's comments above:
It looks like Mikado Supply Wooden blades with the Logo 400 Kit (flybared version).

With the Logo 400 Flybarless they supply it with Carbon Blades or as a bare kit only.

I'm guessing these blades were only supposed to be run on the Flybarred Version with the Mikado recommneded setup, so if you have gone outside of these recommendations it is down to user error.

Also, same goes if the 'User' has modified or converted the mechanics from Flybar to Flybarless, the standard kit and instructions will have been centered around the flybarred kit. I would hazzard a guess that there is some recommendations in the flybarless conversion kit for blades usage.

My Logo 500 exploded on me yesterday.

The cap bolt on the spindle snapped mid flight. The 'bang' mid flight... and the heart stopping moment as I watched the heli drop helplessly to the ground

It was a tearful moment....

Due to where I fly, and the long grasses, It took me 1/2 hour to find the blades, which are still intact, and has saved me buying new grips, bearings, blades and links

...Best part of it is that it will only cost me about £50 to repair...apart from my lovely canopy is now scarred

Not good to hear Andy!! Glad it wasn't too bad. Do you deoil/grease the spindle bolts before installing them? Mikado bolts normally don't need this but it's good practice anyway. My 450 pro had this issue for a while (3 crashes, new bolts/shaft every time) until I degreased them bolts first!

Also +1 on SynergyMAN and Janek.

Hi Laurence,

The bolts did not let loose, so it wasn't that there was grease or oil on the threads. The Head on the spindle bolt had 'snapped off' one side. The rest of the threaded part of the bolt is still in the spindle. I will degrease all my bolts from now on though!

Also.. when I found the blade and grips, I also found the snapped off bit of cap bolt!

Hoping to get the parts tomorrow and start the repair.... but hey, I got to get some new low profile white skid set! Hope to get it up and running by the weekend

I checked Toms "Logo Instruction Manual" after his accident. I hadn't realised he was flying with wooden blades (all nicely plastic coated white) and I immediately scanned through the manual for recommendations about head speeds - for any type of blades.

The kit came with the blades - I don't know whether it was a flybar kit or not. Regardless, I couldn't find any instructions or advice about safe rpms for any type of installation. I think that's a shortcoming on Mikados part.

And anyway why does it matter whether its flybarless or not? Flybar helis can run at equally high revs (well nearly).

[Lynx.1677]

So.........there was no indication that the blades were wood?

Quite worrying really. Looks like I will need to buy some blades as I bought the basic logo 400 kit too.

But surely there are more stresses being put on the blades on a FBL heli as the blades are doing all the work and not the flybar,

agree with the rest of what you said though, it is a worry, mikado may need to look at that

Depends where you bought your kit i suppose, but i'll reference this just for an example:Fast Lad Performance

I suppose it's down to Mikado, if they are supplying blades in the kit then they should be fine, although they only seem to supply wood blades in the 400 size flybarred kit and not in any of the 400/500/600 flybarless kits which seems to tell you something.

Flybarless seems to be more demanding on the whole machine, mechanics, electronics and of course the rotorblades!! .. On a flybarless machine the blades are doing all the work as opposed to a flybarred machine where they are not so i would say they are under much more load which is why no manufacturer seems to offer these on a flybarless machine.

Yes, granted the RPM's can be the same but the loads induced can be much much more on a Flybarless machine.

I would have to agree though that if there is no recommendation about RPM's for those blades or any recommendations about blades then it is a shortcoming of Mikado as they do not seem give any instruction for the novice and assume everybody purchasing their products are pro's!!

[Mark_T]

I'm still not sure why those blades were even in the box if that was a FBL kit?

The standard kit manual mentions blades but the FBL manual does not refer to them at all.

[DaveG]

I think we need to hear this from Tom as he will be the only one who can tell us what kit it was, although if Dave has seen the manual then he may also be able to tell us what kit it was as if it was a Flybar kit or Flybarless kit it will have been shown on the manual.

My personal opinion is that the standard flybar kit version is for the not so advanced pilot which is why the kit is flybar and also includes blades, kind of like a Mikado version of the Trex 500 as it uses the same Lipo Packs.

+1 Basic version will never come with as high spec stuff. The V-Bar version has more bearings etc in the head .

Doesn't matter what version or heli if you run woodies at too high headspeed they'll explode.

[adieuk]

tom had put the fbl head on the heli it did come as a flybar version so the blades
should not have been used and tom should have used c/f blades but i think tom nows he as made the mistake with not putting the right blades on.....
