Congrats on the BX-maiden :D

These are BLS servos, and I am inside when doing this. Don't know if this is normal - will check around on the interwebz.

The amount of movement you put this thing through in 3 minutes is FAR more than you will ever put it though in the air. No air flow, sitting static and being moved that much will cause anything to heat up. Sounds like it's ready for the air to me.

did you apply any counter force on the blades or the swash plate? This is necessary in order to get reliable results. You need to get the current peaks which cut the voltage down.
If no counter force is being applied this test is like testing a car in a garage while lifting it up and pushing the accelerator pedal down the floor – the engine will run at high rpm and get hot but as no friction is applied on the wheels you never know if the engine has enough power to take you over a hill

No. The Spektrum manual states to EITHER apply force on the swash OR stir the sticks without resistance for three minutes.

Did you set up your Fixed end points for the CC ESC. It took me a while to get that sorted. Ended up having to rebind the RX then all worked smoothly.

Seeing I haven't gotten my batteries yet, I'm unable to power the ESC - so I haven't gotten a chance to look at the settings. Endpoints? Is that when you tell the system what's max and low throttle?

Yes its different to other escs with the high stick beeps low stick more beeps. With this one you put your travel limits for throttle to 50% plug everything in then put your stick to high and slowly increase the travel limits till it beeps then move to low stick and increase the travel limits till it beeps. Thats it. I have done three flights now without setting this up. It worked, but spool up wouldn't start till 1/4 throttle. Now it should be perfect. If it ever stays in the air LOL

Not yet. I want to get it all running well first then i'll think about gov. Remember i haven't even finished one flight on it yet :D

btw I would strongly recommend to use a teflon heat shrink tubing on the tail control rod on the places where it touches the tail rod guides

Is this known to be a problem?

A week ago I placed an order at Flying Hobby where I've gotten a lot of stuff lately, the batteries for the JR was on backorder :( So when I picked up my package today I assumed I was getting all the other stuff I ordered which was in stock... BUT WADDA YA KNOW! The 6S batteries was in there also :D :D :D :D

I love that site!

Four packs of APLUS 6S 3800mah 65C batteries :D

I can't remember if this is going to be 6S or 12S. If 6S, are you going to running two in Parallel?
