Hi everyone,
I've recently put together an FT Mini Guinea and had a great time for the first two flights. However since then, my transmitter briefly loses contact with the receiver a minute or two into the flight. The transmitter beeps to indicate that it's lost contact with the receiver, and I lose control and watch the plane crash. It's very repeatable and has gotten to the point where I need to rebuild the wing because its taken one too many hits.
I noticed as I approached the plane after the crash, the dropout beeping continues on the transmitter and I can hear the ESCs within the plane are continually playing their startup tone. This leads me to believe that the receiver is browning out and losing power momentarily. I've noticed that at least one of the aileron servos makes the whiney, "I'm straining under load" sound at neutral position, and the problem manifests much more quickly if I put my flaperons down. The ailerons themselves exert a bit of up pressure due to the glue reinforcement on the bevel hinge which the servos would be fighting against.
Would it be possible that both aileron servos being under constant load could draw enough current from the BEC to brown out the receiver? I'm using BLHeli 12A ESCs, and I've read that although its BEC is rated at 1A on paper, it's actually 500mAh in reality. I have two ESCs running in parallel, but only one of them is currently running power to the receiver.
Just wondering if that all sounds plausible, and if so, do any of these solutions sound ok:
a) Run both BEC power lines to the receiver to double the delivered current. From what I understand you can have both BECs running to the receiver as long as they both have linear regulators (which they do) and come from the same power source^ (which they do).
b) Upgrade aileron servos from 4g (recommended) up to 9g to handle the aileron load
c) Upgrade ESCs from 12A to 20A, which has a BEC rated at 2A/5V (I've got 2 spare lying around)
d) Get a standalone UBEC
Thanks in advance for any help/advice! I'd love to get the mini guinea back in the air because it's such a joy to fly!
