I stopped using aileron bellcranks maybe 40 years ago, as I was tired of the added slop and had just buzzed an aileron off a fast aerobatic bird (it was fine). Since then have always dedicated a wing servo to each aileron. The first time I did I was immediately impressed by the improvement in control tightness, and that was the end of linkages for me.
@@richardmiddleton7770 weight is on the wing wherever the servo is in the airplane. A servo with a short pushrod is much less likely to cause flutter than this linkage is. Way too main failure points. Also a servo under a hatch on the wing is far easier to access than one buried in the center of the wing inside the fuselage.
@@cavediver2579 The only difference in flight characteristics would be the roll axis stability, since a plane with mass further out will have a harder time rolling.
@@deathlocus1571 negative, I haven’t flown RC in about 5 years but I’m 62 and started flying RC when I was in my early teens. I progressed through the regular sport planes to, Q500’s, pattern, and ultimately to Jets. I started flying Jets with the JPX and Turbomin turbines so I have a little bit of experience with RC. You’ll never see the difference in roll rate. That more of a function of control surface flows than the mass of the wing.
The ouly thing of putting servo in the wings is it add weight toward the outer wing . That is not good if you think about it . The wood thing . If that is the case then wood spars would not be good ether .
This wouldnt work since the crank arm sticking out of the wing on the ailerion will cause issues with air flow. One option is to mount the crank arm on the bottom and make it quite small.
@@shelbyseelbach9568 Maybe he was worried about gross weight and running both ailerons off a single servo was the objective. Also keeping the moment centered on the longitudinal axis probably gave a quicker roll rate.
No offense, but I would not trust that design. Wood is not a good material to make push/pull rods, and having that long piece not guided will just make it deform if the force gets a bit higher. And having the cornerpiece as an L is really bad design choice, it creates unnecessarily high loads around the bearing which will lead to it breaking quite easily. A quarter disk would be a lot more robust and has a diffentiable flow of force. Corners like that are deadly. Overall, don't use wood on high load moving parts, its is really not suited for that. Nice job on the structure itself tho, it looks very clean.
