Hey guys I have a Trex 450, that I just put in a flybarless unit into, I am using the same blades that were in the flaybar set up, but I am having a slight vibration, actually I can see the heli shaking while hovering, I was told by some people that it is due to the blades.
Is this true? if it is, what is the difference between FBL and FB blades?
Thanx in advance, I kinds feel like this should go in the noob section, and sorry if this is a stupid question.

It may be the blades but its not because they arent FBL blades.

ok in that case do you know what the difference between the two any ways?

Fudge, it is generally weight and Center of Gravity. The FBLs are typically a little heavier to compensate for the paddles that have been removed. Might seem counter-intuitive, but the paddles performed thier job, in part because they are throwing their wieght around at a 90degree angle from each blade.
FBL has the CoG a little further from the center of the disk, and a little heavier on the out, places system vibration and balance mechanically on par with the FB's, then the electronics do the fine-tuning from there.

edit: correct my wonderful sprelling skiilz

ok thanx man, so does that mean that regular fb blades would work on a fbl setup with out any major issues?

Yes the FB blades work just fine and i like them better then most of the FBL blades i have tryed for 3D.

I like fb'ed blades better than fbl blades. Have you balanced your blades?

Fudge · 08-29-2011, 04:46 AM

Yup blades have been balanced, finally figured out what was up and seems that the swash is out of round!
Thanx for all the help, I did buy a set of fbl blades too see which I like better!

There is one other differance, if you hang FB blades they hang off to one side and FBL are weighted to hange straight down along with them being a bit heavier and the COG moved a bit
