I'm having problem with ESC . When spooling up it start off in soft start but when it get to 30% stick it jumps to set headspeed 1850hs. I tried starting in Idle 1 at just below mid stick (about 5 degrees) and use Thro Hold to start , it did the same thing. I didn't notice yesterday as i was at home in thick grass but at field is very short grass so the heli spin about 240 degree before tail catchs it. Besides scary the ---- out of me ,it has cause the blade to hit blade grips I've try lowing the intial spool up rate to Low (2) but that did not help at all. I had 2 other guys at feild look at my setting in program and radio and no one can see why it's doing this.
Here's my setting. Once it spooled up it's fine.

Castle Ice HV 120 ESC

• Normal Idle 0-30-30 Flat
• Idle 1 70 Flat
• Idle 2 100 Flat
• Settings for Governor Mode: Set RPM
• Initial Spool-Up Rate: Medium try Low still did it
• Head Speed Change Rate: Medium
• Governor Gain: Low 15
• Battery Pack Voltage: 3.70 (adjust settings for 12s)
• Motor and Gearing: (adjust settings for 115T main and 12T pinion,
560KV motor, 10 poles)
• Desired Head Speeds: 1850, 2000, 2075

ANY IDEAS ?

Never mind ESC is dead. just tried plugging in Battery and not even a spark form 12s.. Go figure.. well i got 1 good flight today and it's in 1 piece and not burned up.
"Merry Christmas to all and to all a good night."

AS for the CHP 700 : I only got 2 flgihts 3 minute long but Heli felt great. I thought for sure it was going to feel heavy in air but moves so quick and smooth I never noticed a heavy feel. Can't wait to really get some air time on her..

Ben, yes, my gov gain was way too high along with improper mesh setting and I was "feeling" it out at that point, but didn't get another chance to fly due to time and weather constraints. I believe I have since lowered it to 15.

Gernejr,

If you had Auto-Rotate function enabled, your Normal Throttle curve should have been 0% flat.

I think a 560kv motor is way to high for the head speeds you want. Though your temps seem alright...

Maybe Ben can chime in on this and give some insight.

Sorry that your ESC is not working =\ You'll get it sorted out!

Also, did you follow the "instructional documents" at the bottom of this page?:

Hmmm but why did it still spoolup to quick with Auto-bail was turn-off and Now why won't it connect or spark?

Now on my 550 with Ice 100 I have auto bail on and 0-30-30-30 the first 30 at 25% stick and it works perfect. Spool up smooth .

just be sure to double check your setup was as per the castle docs...

if the ESC isn't operating at all, then I guess it'll need to go back to Castle for repair. i'm not entirely sure what caused the unit to fail, but maybe the data stored in it will.

I ship esc out monday ,CC got the ESC today .They check it out and say it was defective and shipped me out new one today 2nd day mail should be here Thursday... I'm paying the Express shipping to get it here thursday so should be Flying All weekend.
Tech going to help with Auto-bail setup with me to make sure I get it dail in. I did setup auto-bailout wrong as i had it 0-30-30-30 funny thing is my ice 100 is setup that way and works perfect. I'm going to resetup Ice 100 after i setup the HV120 with tech.

Thank YOU Castle Creations along with Darkfa8,Dr.Ben,cgboleand everyone else for your help.

I did install the 700E CF Linkage rod set H70068T only required little shortening of rods and CF tube when using QuickUK short ball links.

i did post the instructions on how to properly set up the ESC:
If you had Auto-Rotate function enabled, your Normal Throttle curve should have been 0% flat.

"instructional documents" at the bottom of this page?:

http://www.castlecreations.com/support/documents.html
It may work on your other model, but obviously isn't setup as per Castle's instructions.

Either way, sorry to hear your ESC was defective. Fortunately in your case you didn't loose your entire model as a result. Others have not been so lucky.

I wish Castle included the complete documentation with the ESCs and that their quality control was better. People have had their models crash, catch on fire and destroyed as a result of defective ESCs or improper setup due to not knowing about documents online. If their ESCs weren't so cheap, I'd probably just save my pennies for a YGE or Kontronik, but I guess being cheap does have its caveats.

Dark I am thankfully it quit on the bench and not in the AIR. Now if i had to buy $500.00 ESC, i still be flying my Nitro.
I have to agree there quality control could /should be better on the other hand they probably sell more ESC in 1 month than most sell all year. I bet for every one esc we hear defective there's thousand working perfect .Also I don't think there a ESC that has all the features the Ice HV ESC has in one unit.

Wahoo ESC was at my house when i got home from work SWEET. IT's in, programed with Auto-Bailout and tested perfect. I did about a 3 minute easy flight at house before it got dark. I did drop the Gain from 15 to 13 as the taill had little wag. Will see if that enough on the next flight. Now if that 11t pinion will show up.
I also redid the Ice 100 in my Outrage 550 ..

when looking at your data, you'll want to adjust your Gov Gain to achieve as minimal a head speed RPM deviation as possible without chattering gears...usually a 10-20 RPM deviation is pretty good.

Once you find this sweet spot, you can work on adjusting your gyro gain(s) to suit.

Of course these is some wiggle room here if the model performs as you want with a lower than optimum gain, it'll be that much less harsh on the drive train.

Update ,First the heli flys GREAT. I changed the pinion to 11t set to 2055HS in Set RPM 95.6% with 11% gov gain. Getting 6 mintue flight of totally unbogable power. Now today in the middle of so hard fast tic toc stripped the main gear. Motor is really more than I need so I'm looking at 510kv or 530Kv really want to try Align 700MX 530 motor.
As for the heli it has 27 flights with NOT one problem. I couldn't be happier with buy the Custom Heli Parts kit.

a lower KV motor would help with efficiencies, but if you're pushing the model hard and stripping main gears, you might be trying to pull too much pitch...

did you set and check the main gear to pinion ear mesh hot and lube the main gear with silicone grease?

Dark , yes the mesh was good and I had added silcone lube. the peak readings were 6641 watts and 166 amps. If .00134 x 6641 watts = 8.9hp.
The Mod 1 gear i'm using is Microheli gear that i had, sure how strong than really are so if this other one strips may try Align or get KDE mod 1 .
I'm thinking lowering KV would be best also like to try some Edge 713 FBL blades and drop my pitch to 12 degrees from 13. The 510Kv motor should be right at 2000 to 2050HS and 713 blades will lower the disc load so the heli will feel little light on Autos.

I would recommend the KDE gear, as it is the strongest main gear currently available. It is also a little thicker than the stock gears so it will provide more tooth engagement surface area (10mm vs 11mm).

Reducing disc loading, pitch and/or weight will always help so long as the performance is acceptable to you.

About the peak numbers, I too was pretty jacked about hitting 7100watts for a peak, but it was just a spike and it's really indicative of the true power. The true power is really what the average is under the curve. There was a long discussion on this forum I think started by Benny Jee (red_z06) about this topic. Anyway, it's a nice number to brag about, but there is more to it.

I'm on the fence about what I'm doing with my CHP700. With the weather being crap here, I've been stumbling through some potential upgrades, sold off the 530kv motor, picked up a 4035-400 and a FAD-Heli 117t main gear, am trying to sell the flybar head to buy a flybarless head. Just not sure where I'm going with the model yet.

Dark, what direction are you going now? I see the 400kv and 117t for sale. Dr. Ben is having a look at my data log maybe he can steer me in right direction. Im thinking 530 /12t @ 2050hs and maybe edge 713 blades might be what im looking for.Sponsored by Visa

I am thinking of parting out my 700 due to lack of funds to be able to support it. I might opt to stick with a 500-size platform since the related cash costs (blades and batteries) are in some cases less than half that of the 700 equivalents.

The most effective thing you could do to optimize your setup would be to go with the 4035-500 motor if you still want to turn the head speeds you've been turning. The 530 technically handles a bit less current and wattage than the 500 (80 vs 84amps, 3400 vs 3500watts), it's not a lot of difference, but if given the choice, the 500kv motor would be the best choice in my opinion for your apparent performance goals.

Going to the 713 blades will decrease your disc loading (a good thing in my opinion), you'll want to decrease your pitch range across the board to maybe +/-10* collective, and 6-7* on cyclic and then feel out and dial it up to what your drive train and power system can support and what feels good to you...don't just mash it to 14* like most people, that will assure you of stripping gears if you try any ham-fisted maneuvers.

Start conservative and work your way up. Most people dial in 14* of pitch and insane amounts of cyclic and expect the model to deal with it...by design, the Align 700 drive-train just isn't strong enough. Maybe with the FAD main gear, and a 3rd bearing block setup (can't do a 3rd bearing block in the CHP frames, not enough material to bolt one into), and lightening the model as much as humanly possible, but it's still a lot of power to try and pump through a gear system never designed for the levels of power the electric systems are capable of spitting out.

Good luck!

FYI, as per the latest version of Castle Link 3.29:

using a 4035-500 (10 pole)
115t main, 12t pinion
*2100 head speed, estimated Power Out 100.7%
*2000, 95.9%

117t, 12t
*2100, 102.5%

117t, 13t
2100, 94.6%

using a 4035-530 (8 pole)
115t, 12t
2100, 95%

115t, 13t
2100, 87.7%

117t, 12t
*2100, 96.7%

117t, 11t
2100, 105.5%

According to Clint Aikens of Castle Creations tech, he's run between 96-106% estimated Power Out and achieved near perfect efficiencies from the ESC where the actual recorded Power Out during flight was bouncing off 100%. This is what you want, you want the MOSFETS in the ESC to be switching ON as much as possible, but not ON constantly otherwise they will overheat.

Every setup will differ and may require some experimentation with gearing or motors to achieve an optimal setup.

*likely most optimal combinations

Not exactly. You could take a model with no blades and set the headspeed for 500 more rpm than gearing and kV will ever allow to it turn. The ESC will run 100% all the time and still stay perfectly cool with no load. Forcing an ESC to run with the FET's turning on and off at high frequency such as occurs when running a low rpm hover with tall gearing generates heat as quickly as anything I've seen. After that, heat comes as a function of power being asked of the system, and it only increases with the current exceeds the capacity of the ESC and not simply because the FET's are on all the time. A FET that's on all the time and working within design current parameters is as happy as a proverbial clam.

It should also be remembered that estimated power outs in the mid 90's and up will only maintain headspeed in the presence of good batteries. Don't count on a set of plain Zippy 25C's being able to maintain voltage under that kind of demand. A set of new TP's or Hyperions would be another matter. It is for this reason that rpm calculators and even the CC software are good for little more than getting you in the ballpark on a set up. You MUST, MUST, MUST log the data and then be prepared to make fine adjustments to gearing to get the system truly optimized for your flying style, motor, gearing, and batteries.
