Logo 14, A note on the #4019, bridge needs a smaller bore

[OICU812]

Ok so you all know I confirmed that the brdige is in fact the #3037 one, which is the same as the Logo 10. Now the thing is the hole on this particular bridge is 4mm bore, the flybar is 3.95mm outer diameter, now what is obvious about this? Even with a good squeeze I can make it move a touch, I am pretty choked about it! I shot off an email to Dan R from Custom Heli parts to see if he can make some but with a slightly smaller bore, this would bring the solution instantly. Since I am going to be running the metal bridge I am not totally dissapointed, however thought people should know. I think the MA or JR flybar in 4mm fashion would be fine providing they are actually 4mm or 4mm + in OD. That way just tight should hold just fine. The bore itself should be slightly smaller, say 3.94 or so, that would ensure your Mikado flybar would fit firmly as would any other. Mikado you guys should know better, arg!!!!!! :bomb: :arggg:

Hi,

We have been doing 4mm flybar upgrades on the Logo 14's for a year or so now, but had the existing ball bolts reamed out to 4mm by our machine shop. This way, the bridge and bearing IDs are still 5mm, and the spacers aren't required to keep the flybar centered.

At IRCHA this year, we asked Ralf to build the kit to provide an even better solution than we were could, but I agree it could be improved. The kit also includes the Mikado 4mm 3D flybar paddles, something we haven't been utilizing.

I'm sure they would be up to revising the kit if we all got together and listed exactly what we wanted...

Well I did try it and the L10 bridge does NOT secure the flybar tight enough, this I can assure you of. When twisting on the paddle by hand the flybar moved, and this was tightened down as hard as I could. Not a researched enough upgrade imho. I have asked Dan from Custom Heli to whip me up a couple of "small od" bridges out of aluminum to solve this issue and likely will use MinAir flybars as they are stiffer.

A smaller od on the bridge is needed to solve this issue, and as a opinion I feel Mikado should stiffen up the flybars, tired of the wet noodles, my 3.5s' bend after about 10 flights and I have to rebend em down abit, kinda silly.

The thing with Mikado flybars is, they're stainless wich is kinda soft. To secure the flybar better with the stock bridge, just take the lower "clamp pieces" and pull them over a sanding sheet a few times..

I did that Danny and when I was tightening the paddles on it, they still shifted. I liek the way the L14 clamps down on the holder that is a secure fit, the L10 one should be made slightly smaller imho to avoid this.
