Glad you caught in time. Mine broke three ears off, although I had it mounted in standoffs (which I don't recommend)

My feelings as well, rock solid

Perfect Thanks
The motor mount should be here monday. According to the tracking info, its sitting at the postal fascility. Then I can start mounting everything up. Still waiting for the batteries to arrive from HK.
The order is being held up because the Sentilon I had on order is on back order. Since I no longer need it, I plan to call in and cancel the Sentilon Sunday night as soon as they open. Get those batteries shipped

Did the remaiden today as an electric.
The first flight with the 23x10 prop was a dog. It had no pull.
The second flight went much better with a 22x12.
I will be getting a 23x12 for it next. It needs just a little more. With the 22x12, it had just a touch less power than the DL50. But easier to fly.
After the first flight the batteries were warm but not hot by any means. With the temp gun they read 86 degrees. The wires were cool, as were the Deans connectors. The Deans were just noticable that they had any warmth to them. The ESC was cool to the touch. Iwas quite surprised by this. The motor on the second flight was 146 degrees after doing a couple of hovers and some extended up lines to see how it pulled.
There was a small issue with the timing. If I advanced the throttle to quickly the ESC would loose sync with the motor.
One of our local electric guru's checked it out and said that was the most likely cause. He said he recognised the sound from when he had similar things happen to him. I will advance the timing for the next time I go fly it and see what happens.
Overall, I call it a success
Just some fine tuning and it should be a blast to fly. It was nice flying it around slower than with a fueled engine.
Felt relaxing with the quiet and being able to just fly around slowly.

I have yet to fly mine (A60-18L) or even run it up and for the speed control I have installed a Hacker Master Spin99 but the concensus seems to be the CC brand, Is there a known prob. with using the Hacker Master Spin99 that I should be aware of? Thanks for any info guys!!

We run the A60-18L on Castle 110HV. 24x12 APC E Prop. 12S 5000mah. ESC settings:

V1.55 firmware
Low timing
Acceleration 3
Current limiting off

If you don't set the Timing and acceleration values, it will screech when you apply throttle.

Anythig smaller than a 24x12 is bad performance.

[Mr.Pickle]

I have a 24x12. But How bout a 25x12.5, I have one of those too, is it going to be too much?

It did screech if I applied the throttle too quickly. I used the settings you posted earlier as closely as I could. Some of the values you have were not available.
Also, I am using the 16L, not the 18. I don't have clearance for a 24 inch prop. Would that be a big difference in the settings ?
Here are the settings I had. Some of the descriptions are not the same as what you had. And some of the values were not available.

Throttle Tab
Software Vesion: 3.19
Vehicle Type: Airplane
Throttle Type: Auto Calibrate end point
Throttle Response: 5* ( default ) Is this the acceleration? If so, the only value lower is ( 2 )

Brake
disabled

Cut offs
Cut off voltage: 30v
Current Limiting: disabled
Cut Off type: Hard cutoff
Auto LiPo volts/cell: 3.0 ( default )

Motor
Start Power: Low ( 39 )
Motor Timing: Low ( 0 )
Direction: Forward ( default )
PWM Rate: 12khz ( default ) There was no 13. It jumps to 16

Other
Power On Beep: Enabled

Device
Phoenix-HV2 ( F310C )

Firmware
V2.18 ( Beta )

Thanks

The Spin 99 ESC is the hot ticket for the A60

I've been using the v4.1 Turnigy 100a HV esc - yes the cheap far eastern one... It works perfectly out of the box on my A60-18L, 24x12 APC-E and 12s 3000 setup. No screeches or timing issues, and what Rolls Royce would have called 'adequate' power

[3DHobbyShop]

Bdegan - Yes, reduce throttle response to 2. Apparently your later release software, either for the link or the ESC, is different than my older stuff. I've not run Firmware V2.18 on our ESC's. I have no idea if that's compatible with the Hacker A60L of not. The HV ESC's we've purchased recently were still coming out of the package with V1.55 which works very well and so we left them alone. Castle had a couple of bad software releases after 2.0 which screeched on Hackers no matter what. I *expect* that Castle will know the difference if you ask them, certainly they had a lot of angry people calling for a while.

Mith - I disgaree. I have both, I prefer the throttle response of a Castle on 1.55. It's not a huge difference, but since I have both, I can choose.

Jbm - Me too. I have a couple of the V4 of the Turnigy Sentillon 100 ESC's. No problems so far. V4 appears to be the ticket. V2 certainly was not, and I skipped V3.

What about the PWM rate ? Leave it at 12 or bump it up to 16, the next available option ?

[Bdegan]

Can a Firmware or software update be rolled back ?

[jbm]

I just want to say thanks to 3DHS Ben while I think to do so: You've certainly shouted loud about the A60-18L setup, and I'm very glad I listened when searching threads for elusive facts and figures. Its nice to get word out about known good systems; anything that de-mystifies the hobby is good IMHO.

[Bdegan]

Another question. You said to set the cutoff voltage to 30 volts.
If running a 12S setup, shouldn"t it be 36 volts ?
