RE: H9 Funtana problem with elevator joiner flexing
My .02 worth. I just took my Funtana to the ground yesterday... I was flipping all kind of switches and when I was level and close to the ground, pulled back on the elevator and in 3D mode high rate, snapped it into the ground. What an idiot, huh? Well, I said I'll never do that again but actually I will and I know it.
I thought the same thing about the connecting rod not being stout enough and letting the non-servo controlled half "flex", thus allowing it to snap or at the least, not maintain full and equal throws. What I have found out through flying Funtana's is that the connecting rod as is will suffice for the two elevator halfs. The Funtana, as it's set up with only one elevator servo will do exactly the same thing than if you have two rigid servos mounted. I've flown about 7 different Funtana's. Two of them had dual elevator servos. They all have the snap tendency with excessive elevator throw, especially with the CG at a rearward location. Having about 100 flights on mine, I got a pretty good idea when it was going to go into the snap routine. Again, flying the dual servo elevator Funtana, I really didn't see that much difference when the snap was going to occur.
Anyway, I need to order another Funtana, and soon. Eventhough I've just explained that there's no different flight characteristics between the single and the dual elevator setup, I'm going to modify the connecting rod setup too. I would just feel a lot better knowing that the two halves were solidly connected.
