I'm just putting one of these on my Trex 500, do I use a standard 500 mainshaft or do I need a flybarless mainshaft?? Thanks

I have used them both, flybar or flybarless, depending on the fuselage style and if you need or not the longer shaft. Either way will work....

Problem is, when I use a standard fly bared mainshaft I cannot get zero pitch at 50% stick. The links from the servo horns to swash are not long enough. I was hoping that a fbl mainshaft being shorter would sort the issue out? Am I correct? Thanks

ESP H50086 153.3mm
FBL H50133 148.8mm

It will lower the whole head by 3.5mm or you might have to get some longer rods off another model

Thanks OZFlyer, I don't suppose you could suggest any suitable links?

Thanks

Jim

Hi Jim

Standard length for ESP 3 x Φ1.96 x 31mm
here are some options

550 rods H55048 3 x Φ1.96 x 39.5mm
600 rods H60161 3 x Φ1.96 x 39.5mm
550 rods H55049 2 x Φ1.96 x 44mm ( you would need 2 packs)

Steve, with the swash midway between head and mainshaft collar. The distance ball to ball is 55mm. I can't help wondering if there is something else not quite right here as no one else seems to have posted anything about needed longer links or different mainshafts??

What do you think?

Having the swash mid way on the mainshaft is a 3D thing to get equal travel +ve and -ve and you wont be needing to go to -12 degrees you can move the swash lower by lengthing the blade rods a little as long as you still have clearance. Are the arms level?

Standard length for an ESP between balls is 50mm a FBL main shaft would just about fix that.

Other people might be starting wit a FBL heli with the shorter shaft.

Yes I get that, I won't be doing 3d with it :-) . I'll order the FBL mainshaft and I might order some longer links as well just in case. I'll post back in due course, thanks for all your help.
