How hot should the 5.3V regulator run.

[Degzie]

Hello Guys.

I would like some input on as to what temperature the 5.3volt regulator should run at with this load & equipment.

-3x JR 8511 CCPM
-1x JR 811 THR
-Futaba GY611 with 9256
-TJ pro
-JR 649 PCM RX
-5.3V reg & a 4000mah pack.

I am experiencing some strange lockout (see post on MA forum) & can feel the regulator is almost too hot to touch after five mins of general F3C flying, I have a R50SE with similar set-up & the regulator is not as hot.

This temperature is acheivable with the heli on the bench engine off & moving the sticks for four mins.

Your input is always appreciated. Thank you.

Do you have the regulator mounted out in open air under the canopy?
The regulator will get warm, but it really should not be hot to touch.

I read your post in the MA forum.
How do you have the Failsafes set up on the transmitter?

yep the reg is mounted at the front of the radio tray in front of the battrey. not covered, even when I remove it from the tray & dangle it from the wires it still gets hot.

The failsafes are set to zero pitch, throttle cut, gyro to hold.

Ok so you don't have Failsafe set on the channel controlling the TJ pro. You would need to have that channel set for the TJ to cut off.
If you don't have it set up this way, the governor is keeping the throttle at the set speed. That could be why the heli jumps a few times in a flight. IT is going in and out of failsafe.

When using a governor, you have to set the governor channel to turn off in failsafe also. And tell the throttle channel to failsafe to idle or engine off.

Well I think we have a result.........Fantastic.

I would first of all congratulate David as he was correct in saying the rx was going in to failsafe, Thank you David & many many thanks to everybody else who contributed.

It was Davids point & a note raised by none other than Ron Lund of ricks helis, that helped me track it down, well I think so 3 good fiights & no lockouts or sudden uncommanded movements.

It goes like this..........The GY611 gyro uses a very fast servo that subsequenly uses alot of power during flight, it was this large power consumption that was causing the problem & had routed the antenna wire a bit too close to the servo harness & I think this was causing a problem.

I will be flying some more on Saturday & I will let you know what happens.

David AND Ron Lund ROCK!!
