Can the Castle Creations Phoenix Ice Lite 75 be used in the 500EFL Pro?

The CC 10Amp is not a very good choice BEC using a 6S setup ,better suited for 3S or 4S voltage ! Think you will find it not much better than the internal at 6S voltage. I would recommend the CC Pro 20A over the CC 10A or Gryphoon Polaris if your worried about size of the BEC for installation. The Polaris is a very nice little unit and much more capable than the CC 10A in a 6S system.

I've had a 10 amp BEC on my 500, with over 160 flights on it. I've never had an issue, and I'm not the most graceful of flyers, so I work the sticks over pretty good. I'm also using Align servos, which are known to draw a lot of current. I'd be really surprised if a 10 amp BEC isn't good enough for a 500 (425mm class). I would put a 20 amp on anything larger though.

Now i got my 13t pinion. Will fly governed -- looking to get 2200-2600-2900/2950 on my normal mode with 2200 would my pitch curved changed from 30-40-50-75-100 to 0-40-50-75-100? Im alittle out on that pitch part, thanks.

[Gladius]

2200-2900 is a huge range of head speeds. At 2200, you're most likely going to have some pretty bad tail authority issues, and switching between modes may strip your main gear. People looking to run that low of a headspeed typically have a dedicated setup (4 bladed head, tri-bladed tail, larger tail blades, etc.) which then prevents them from running higher head speeds.

Also, what is your purpose in changing pitch values? You aren't getting any extra positive pitch with the change, and you're introducing a kink in your negative pitch which is almost guaranteed to cause a crash IMHO. I would recommend that you just use a straight 0-25-50-75-100 pitch curve in all your modes.

Thanks gladius i work on it but when im i TC my normal PC in that range and iup 1 and 2 and on HOLD is linear work fine. I Take off on normal mode. But what head speed do i really have to achieve without causing too much trouble? is 2400-2600-2900/2950 really not ideal? I know trex 500 need high head speed but not over 3100, i think.
Thanks and merry christmas.

My setup was 30-40-50-75-100 on my normal mode ungoverned didnt crash. What i am trying to get is the pitch curve on normAl mode governed, as i stated my 1st point is 30 on pc on normal with tc of 0 its idel right, that is when it was ungoverned.
Thanks for enlightneninf this part.

You could try something like 2600-2750-2900 for your headspeed, and 2600 might still be too low. I have an ESP, so I don't like flying much over 2650.

As for your PC, with 30-40-50, you still have a straight line. You're just limiting your negative pitch to about -4* with full negative collective. The top half (50-75-100) of your PC is also linear, but where the slope of your PC changes is at midstick, which is already a breakpoint between positive and negative lift. Your new PC causes a drastic change in the slope of your PC at quarter-stick. So let's say that the wind gets a hold of your heli, and you're giving it some negative collective to bring it back down. You feed it a little, then a little more, and then you pass quarter-stick and your heli starts rocketing toward the ground because each movement of the stick is now causing 4 times as much change in pitch.

Again, my recommendation is that you set your pitch curve to 0-25-50-75-100 IN ALL MODES so that you learn how much pitch a change in stick position is going to give you.

Gladius, so today it flew nicely, i changed my N PC to0-40-50-75-100 N TC 0-45-70-70-70
First flight just have to set my gyro a little lower, my head speed is noticeably higher i havent set the governor, but i like my pitch now, thanks i think i set up wrong before. It takes off slowly and no dramatic climb up, with the zeal tail blade its wider that the one i have it adds up really happy i might try 2500-2700-2950 on my governor, and start with 10% gain...
Thanks again happier now.

Having a PC of 30-40-50-75-100 in NORMAL MODE will NOT cause a dramatic change in pitch at 1/4 stick, in fact it will be just the opposite, the PC from 0 to half stick will be a gentle slope and will NOT make the helicopter rocket to the ground in the event that you panic and lower the left stick a little quicker then you intended to, on the other hand If you have a PC of 0-25-50-75-100 in NORMAL MODE and lower the pitch stick your helicopter will move toward the ground at a higher rate of speed then if you had a PC of 30-40-50-75-100.
doubletap you had the right idea in having your a PC of 30-40-50-75-100 in NORMAL MODE. If you have a pitch gauge, set bottom stick or point 1 in NORMAL MODE to -3 to -4 degrees pitch, skip 1/4 stick or point 2 for now, set mid stick or point 3 to 0 degrees of pitch, now to set 1/4 stick or point 2 you take the number in your radio for point 1 and subtract it from the number at point 3, then divide that by 2 and add that to point 1 to come up with the value for point 2. so to illustrate that, let say you have a point 1 of 28 and a point 3 of 50, 50 - 28 = 22, 22 divided by 2 = 11, 28 + 11 + 39, so your point 2 would be 39.
with that being said, a lot of people don't use a NORMAL MODE. if you don't use a NORMAL MODE then you should use a PC that is linear for all of your IU modes. This is the same way that Ray from Ray's Heli Tech shows you how to set up a heli.
I would highly recommend that you NOT use a PC of 0-25-50-75-100 in NORMAL MODE. This is the same way that Ray from Ray's Heli Tech shows you how to set up a heli.

it sure wont i flown mine from the first built,then i tried 0-40-50-75-100, i like the 30-40-50-75-100 on normal mode- i am also playing pitch curves on sim--- thanks

I said that having a pitch curve of 0-40-50-75-100 would cause the heli to start rocketing toward the ground once the throttle was lowered below quarter stick. 30-40-50-75-100 is a fine throttle curve for normal mode, but I would still recommend that you fly in idle up with a 0-25-50-75-100 pitch curve.

Thanks for clearing that up. Sorry if I misunderstood.

This is how i set up my TC on NORMAL MODE- 0-40-70-70-70 with PC 0-40-50-75-100 on NORMAL MODE first outing, 13t, speed fuselage, 430 main, 72 zeal wide cord tail rotor, it flew normal no drastic or rocketing to the ground. Just tweaked my gain a bit (gpro) my PC on IU1-IU2 are linear and my TC are tweaked around flat curves, i liked it i have no issue pitch and tc wise, like i stated i like 30-40-50-75-100 PC BUT 0-40-50-75-100 works just fine i tried it on both of my 450l and 500 thanks again gladius. But my original concern was IF ever i decided to run governor what pitch curve on NORMAL MODE is IDEAL, as iu1 -2 will remain linear. Thanks.

You are better off using either 30-40-50-75-100 or 0-25-50-75-100 than you are using 0-40-50-75-100. What exactly are you trying to accomplish with that curve?

i guess i have to get it myself since this part is personal preference,, i am trying to think is when i let go off my hold switch with my 2500 rpm normal mode headspeed on governor mode soft start is the heli wont get pushed down while on the ground hasnt taken off or wont rocket up in the sky. but i will play on my smaller heli to get the answer for my inquiry. thanks.

You always release TH with your collective stick centered so you are at zero pitch while it spins up. This is the normal procedure no matter what heli or how you set the curve up, assuming you have 50% as your middle value which should remain constant throughout all modes.

Thanks now i get it. why i didnt think of that 0pitch mid stick , yes 2 other flight mode is at linear 50 center. thanks and good to read from you xrayted!

Well, after a long delay I finally got around to installing this ESC into my Trex500 PRO EFL. I mounted it in the stock location under the battery tray. As I stated originally , I already had a Polaris BEC on the heli so the BEC was sorted. I have fitted a 13t Lynx pinion,
and have 3 governed HS, 2600, 2720 and 2820. First flights I noticed quite a severe (about 45degree) tail swing out in steep pitch pumps, so I changed the gov gain from default 15 to 13. I also tightened up the tail gains and collective to pitch in the GPRO and now have dream heli, rivalled only by my 250 and my 600.
I measured the motor (stock) and ESC temps after 5min flights in Idle2, with take off and landing in normal mode. In ambient temp of 24deg celcius, the ESC came down at 38deg celcius and the motor at 32deg celcius, so any fears of heat induced failure on the ESC are now allayed. Thanks to everyone who posted their thoughts and advice on this mod. Would I do it again? For sure!!
