| there is no 'best' bladeFor a long time I swore by NHP 105s. When I switched to a Futaba 401, the only way I could get the tail to hold as well as it should was to use SAB's long tail blades with the rounded tips. I tried all kinds of stuff - different blades, different servo arm lengths, different tweaks to mimize vibration, whatever. Only those tail blades solved the problem. It's weird, because when I was using CSM 360s it seemed like the more tail blade I had the better off I was.
So anyway, I guess my point is that you CAN run up to 105mm tail blades (to answer the original question), but that may or may not be the best choice. Buy a few different kinds, fly them back-to-back, and see what works best for you.
One word of caution - if you use NHP 105s with NHP 710s and blade tips, you need to set the tail blade 'phase' to avoid knocking the blade tips off.
Since the SE has a constant drive tail with a 4 2/3 : 1 ratio, the tail rotor will always be at one of three angles when the main blade tips come by. Picture a six-pointed star (or a hexagon) where the tail rotor is, and set things up so the main bade passes between the points of the star when it's right over the tail rotor. I knocked off a couple of tips before someone on the Robbe mailing list suggested this. That solved the problem. Now I do it with all blades, just to be safe. |
