What head speeds are you getting on E700

[hawkeye690]

Iam setting my C.C edge 120 in the (set rpm)mode.
!st test using a flat 30% throttle in normal h.s was fine.
Idle 1 is set at 70% and running at 2200 and idle 2 at 100% was over 2500 h.s according to the castle data log..
Just wondering what kind of H.s your running..(iam running the N.M motor,stock pinion).

[gwright]

1350/1550/1750. While it's a bit less than "normal", it's plenty powerful for me and flights are 12 to 14 minutes. Many are using 1900~2100 range

[hawkeye690]

Wow,12/14 min would be great..
Iam really not sure if Iam better off using (high gov or set RPM mode..
Even when I turn down the RPM in the 3 boxes,,my castle graph still says iam in the 2400 RPM range in idle 2 using 100%..
next step I have the RPMs set at..1700,1800,1900 using SET RPM mode..
I would think 1900 RPMs would be good for mild 3D...

I'm using 1950 and 2050 with Vbar governor, but I ran the Castle governor (set rpm mode) before that at the same speeds.

This is on a 750MX 530KV with stock 13t pinion.

I fly 4.5 minutes on 4500mah packs, mostly at 2050 and they end up around 3.8V/cell after a settling for a while after a flight.

I'm running 1400/1600/1750 using iKON gov and CC Edge 120 in external gov mode. Plenty of power for me and 10+ minute flights are no problem.

[WessCo]

You might need to check some of your settings. The I.U. 1 headspeed is about the highest you can go with the Castle gov in set RPM mode with that motor and stock pinion. 13T is the stock pinion. 128T main gear. Are you sure that it's in gov mode?

[gwright]

Actually, 1900 is enough for pretty much any type of 3D. It's a very light machine. I fly lots of smooth 3D at 1350, and at 1750 it "goes" extremely well with tons of grunt. Originally I had a 1950 mode with another KV and gear. Wasn't needed and I prefer to setup something with adequate power for my style of flying and long flights, rather than "pop and lock" type power for 3 to 5 minute flights.

TY guys for all your input on this..I do have the C.C ESC IN GOV mode using (SET RPM).
Iam going to set it up around 1700,1800,1900 and see how that goes..
Also,my ESC is really,really warm like getting hot during 3-4 minute short test hovers in my yard.
I know it should run cooler when I can get it out in some good air and forward fly it..I also cut cooling hole in the canopy..
Q.think I should be running a 160A instead of the edge 120hv?....

[WessCo]

Taking a cue from Gary, I installed a 12t pinion on the Nick Maxwell motor. I use the Vbar gov, with headspeeds of 1560, 1760 and 1960. I rarely go into the 1960 speed. Flight times of 10 minutes are possible. My timer is set for 7.5 minutes. This leaves the voltage of the packs just right for a storage charge.

[flint723]

Yes put a 12t on if you do not plan to run higher than 1900. That will help your esc run cooler as well.

How hot is it getting in the logs? I would not be worried unless it is getting above 180F.

[RC Mike]

1900 is perfect for 3D. Anything faster is just makes flight times shorter with no performance gain.

[hawkeye690]

I think Ill try the 12t pinion as I have one here..
AS for temp..My castle graph says its 154 degrees but,I also only hover testing my my yard and only for like 3-4 mins ..ill post back after trying the 12t pinion too..
Another Question,,Are most using a 120A esc or,,should I go with the C.C EDGE 160HV..I know the esc would run cooler with the 160 and curious to hear what you guys would do..
Both of my GOBLINS (630 and 700) have 160s and no problums with either...

[WessCo]

Leave the 120 on it.

[Ricka1]

With 12T pinion, the 120 should be plenty. I'd leave it- just make sure that timing and PWM are set properly. That can make a big difference in temps!

[hawkeye690]

Well for a update..My last test stil using the 13t pinion..As per my castle graph.my max H.S was 1811..it feels pretty good and temp was at max 150 degrees...
As per my PWM I have it in OUTRUNNER mode and timming is set to normal...I pretty sure this is correct..?

[WessCo]

Low timing
PWM Rate needs to be 8kHz

[hawkeye690]

ty for the repley wessco,,Ill set it there !
Can I also ask,When pitching up do you get a bit of tail blowout? Iam on another forum also trying to get this figured out..(using the IKON controller and using tail precomp too..
Sorry if Iam going a bit off the motor topic..Just trying to get the E700 dialed in..

I don't know why, as I don't know what the difference is in the controller's function, but I've been told by many folks to NOT use outrunner mode in the castle esc. After years of running another brand esc I'm trying some edge controllers now, so although I have about a decade and a half experience with electrics (yes, from back int he nicad days), I'm only just learning to speak castle <G> the last few months.
I've done just about everything to get the governer acceptable, it's my only complaint, and I'm at the point of giving up and just using the CGY750 governer. However, higher switching rates can help throttle response, and governer, so I'm currently at the highest PWM. I think it's 24khz, but would have to look to be sure. Motor runs noticably cooler, more efficient judging by flight times, governer just barely perceptably better,.. but ESC gets a LOT warmer with the higher switching rate, so if you try that, watch the ESC temps in the logs. I'm still not hitting over 150, but with 8khz I was at 120 degrees, so although it's still just fine, it does make a dramatic difference in temps. I'm using much lower KV motors (450 and 400kv motors in my machines), so with the higher kv stuff most people run you may not get away with the high PWM, but thought I'd share. I do fly long enough for full temp saturation as most flights with my setup are at least 12 minutes and regularly go 14 till the telemerty alarm sounds for 80% battery usage.

What size tail blades are you using? I use Rail 116. The stock 105's are not big enough, in my opinion. Have you tried raising your tail gain until you get a wag?
