My Posts This: Topic Forum | Hi,
On mine, it can't be upside down because if it is the head can't bolt on.
Pleased to hear this, as I suspected the same issue (I mentionned this somewhere in my build thread) but never managed to conclude. I'll measure mine this evening and tell you, it will be a little approximate as I don't want to take it out now the whole thing is assembled, adjusted and flying really well
On mine, I suspected this because I couldn't achieve descent pitch range, all the head push rods seemed to long and the guide pins were too long too so I wondered if it wasn't the shaft that was in fact too short (I'd say about 1cm too short, if it had been 1cm longer I would have been fine I think).
For now I've used some push rods from my HawkSE and grinded the guide pins. At the end, I have a good setup : -12 +12 degrees, with still some room for cyclic movement at the extremes. It flies really well and it has plenty of pitch range. But it was a fight to achieve.
But if it turns out the main axl is too short, I'll contact Century again to try to get the right one (and also the guide). That way, after first crash, I'll rebuild it back "stock". Because as is, if my axl is too short, maybe I risk a boom strike.
I don't think there are many 620SE around, as it's hard to get peoples feedback on building/using it (most people have 550 or 16). |
