RE: Flight controls power requirements and servo sizing
Oli,
This is re-posted from the Weatronics 'Gigacontrol' thread as you correctly suggested.
I really should go back into this thread and do my own research, and will do when I have time in the next few days. However, until then here's my issue: I have a Eurosport with 2 x servos (8611s) per single elevon, previously matched using a Powerbox SC-12 and 35/72 Mhz radio. Dave Wilshere recommended this setup as it gave a more 'locked-in' feel of control when he did a review in RCJI for the Eurosport about 4 or 5 years ago (!) Now I am converting to a Weatronics 2.4 receiver which could mean I can remove the Powerbox providing the servo power loads don't exceed the receiver's 10 amp limit. Despite the Weatronics' programming capability to match the servos without the PB, I am now considering reverting to one servo per elevon (as indeed most ES owners have) but would like to have a better understanding of the likely servo mechanical and electrical loadings with that setup. Assuming the loadings are within the servo and receiver capabilities, it would be good to revert to a simpler and lighter setup. Two extra 8611s put the balance point further aft so I have cmpensated with nose-weight and it would be good to shed this if possible.
So, any pointers or thoughts will be appreciated.
Cheers, Andy
