[NSRCA-discussion] Brio 10

[Jay Marshall]

It is rated at 25A continuous and 35A surge. The programming instructions
says that the "Current Limiting" at the standard setup (used) will provide
"moderate over-current threshold, will shut down after a slight delay". The
issue may be what is shut down. If it is just the motor, then good. If,
however, it is the motor and BEC then very bad! In any case, I wouldn't
expect any overheating with this protection enabled to the extent that it
would melt the solder on the ICs.

What it sounds like to me is the Phoenix 25's are being used outside of
spec.  Following threads on RCGroups most of these setups for the brio are
pulling in the high 20's to high 30 amp range.  I believe most would be
better off with a 35 or 40 amp speed controller.

HI Jay,

I had the same situation with the Phoenix 25 in a Quiet Storm. Had about 20
flights on it with no overheating and then on the last flight the ESC
unsoldered it's self. Same result - at first my brain said - deadstick no
problem - then I realized just how dead my "sticks" where. as it plowed
in....

aggghhhh!

wondering if it's a manufacturing defect....

My little brio snap rolled to it's death this past saturday. I was doing a
stall turn with a easy pull up from the down leg. Nothing hard or sharp.  I
was on low rates. I was just feeding in elevator while slowly advancing the
throttle. and whammm, a couple quick snaps to the right and well, slamm....

I really feel like I have no luck with these little electrics. I am thinking
about selling all the electric junk - oh -  I mean stuff that I own....
Besides that they fly like small toy airplanes and I don't feel they help me
much as a practice pattern plane anyhow.

I get more out of Aerofly sim for practice.

good luck to anyone with the little Brio - lots of hype there. I was really
dispointed right from the first flight - not great performance here - I had
about 10 flights on her. and thought that the Quite Storm was a much better
plane that flew more like a bigger plane than the little brio.

The Brio seems to fly like it's about 6 oz over weight even at 32 oz....

I guess I am going to put up a garage sale on RCU, I've got a couple of
Tourque outrunners, 45 amp Airboss ESC, a couple of 2100 packs and charger,
8 micro servos etc....
