Mr. Simpson, well I'm sorry to hear about your bad experience with the Align ESC's. I personally can't complain cause I've been using the heck out of them to include their 35A, 60A, 75A and now their 100A. I've got about 20 flights now on my 600 with the 100A and 650l and no problems. I do admit that my past experience with the 35A in gov mode wasn't very good when running it on 3S but it work a lot better on 4S. I've been using the eMultigov for my gov ever since and now love the setup's. I guess time will tell if my 100A will ever fail. If it does, I'll do a auto, come home and order a CC85 and start my 8S build

BTW, is that 15 tooth the helical or straight cut? Have you ever measured your motor and ESC temps post flight?

thanks missle

no i havnt thanks for helping
but the way i look at this is..you get the 600esp and fit the motor and speedo as mentioned/supplied in the instructions.what else can i do..if the temps up..what can i do ??? its not cut out on thermal overload..but stefan simmons my son(clubman 3d winner)has been flying it and i guess he works it harder than the average lad,but it should be designed to do the job.my friend has a 600l motor and 75amp speedo with no problems and stefan been flying his 500 and no problems at all..so the 600 should take the same abuse
i would be happy with the align speedo's if they worked dont want any gadgets or bells and whistles just a working speedo
there must be problems if we have had three speedo's go with two motors and midland helicopters where i purchased it from havnt been very helpfull..ill let you know how i get on with them this time

Mr. Simpson,

I think I may have come up with something. I'm guessing your running everything stock on the bird to include the main gear and a straight cut 15 tooth pinion. Doing some calcs (using Darkhorse), at 100% throttle and 0 pitch, your HS is ~ 23800 at 35 amps (using 23.4V under load); at 8 deg of pitch, your HS is ~ 1829 at 110 amps (using 23.4V); at 12 deg of pitch, your HS is ~ 1353 at 143 amps (using 23.4V). The point being that if your using the stock straight gears with the 15 tooth pinion, the 1220kv 650l motor, and the 100a ESC, while your son is flying some awesome 3D routines, then that mey be why your ESC's keep burning out.

Hi Craig

Might as well tell you straight that for a flyer of Stefan`s ability you have gone very wrong here. The Align 600e is a fairly heavy heli in this class, those motors are not the best and the Align speedos are crap. You might want to cut your loses now and look at the Logo 600 V-bar with a good 10 or even 12s setup.

Flybars. Who needs `em.

YES IM SURE YOUR FIGURES ARE CORRECT...BUT.....
the first time it never flew.i did the setup on the bench running it a few times on the bench at very low rpm.then put the blades on the helicopter and went to the flying field, when we started to increase the throttle it went pop..it never flew

SECOND TIME we did the same setup system went to the field out the back of my house.did two gently flights everything was ok then we went to the field and it went BANG while spooling up..

THIRD TIME..after a couple of flights..
it didnt go bang or anything alike.it just didnt do anything.so sound.so smell nothing.

on all speedo's i noticed the soft start was rough sometimes and ok the next..on two motors because i did question the motors but appears its not them.its like a mis match between the two

new batts are brand new flightpower 6s
everything is new on the helicopter
cheers guys

Okay. Now I see and yes you've definately gotten a hold of a very bad batch. I'm assuming you've been in contact with Align about these crappy ESC's that you've been recieving? Any chance you're BEC is the culprit?

hey missle

Where did you find that chart? You`re tell us that between zero pitch and 12 deg its normal to loose a 1000 rpm. You`re either reading it wrong or who ever wrote it was on some pretty powerfull stuff. How could a bec cause this problem, he said he wasn`t using on anyway.

hi tosh i imagine he was on about the regulator ??? as the speedo doent have a bec and thats why it needs a seperate batt supply...bec doesnt need a batt..meaing batt/eliminated/circuit allowing you not to use a seperate batt supply..???and is powered by the main lipo

it doesnt really matter i checked the regulator its at 5.1v aprox so thats good

cheers guys

TOSH, I wasn't using a chart but rather using the Darkhorse heli calculator. Whereas I can't vouch for it's accuracy, it has helped me greatly for setting up my heli's and I know lot's of other use it here. Give it a shot with your heli calculator and let us know what you got cause your correct that I could've read it wrong.

As for the BEC, it's it's the ONLY other supplier of energy to the ESC (via the rec and all), then I was just trying to rule out other possible culprits. I've even seen a servo that was shorting out, actually ruin a ESC (as well as the gyro) so just trying to go down the list. BTW, I don't recall him saying that he didn't use a BEC cause if he's using an Align 100A ESC, then he'd have to be using an external BEC of some type (unless using nicad plugged straigt to the rec).

yes matey..timer set a 4 minutes thats all..using align reg and bat which i have checked at 5.1v no problems there
new flight power 6s 5amp our sponsored lipos
there is no reason for the speedos to go in my book.it looks like just rubbish align electrics to me
dont matter about amp rating etc or flight times because these speedo are just going almost instantly..as mentioned prior
one before it even flew
one after a couple of very short breaking in flights
and this one just didnt do anything..after a couple of flights we took it home and the returned to the field plugged it in and nothing ..no bleep..peep..or poofs..nout
stefan was really upset
cheers guys im of for a drink with my brothers

That "align reg" your referring to is the 3A Align BEC or are you referring to the 5.1V Align Voltage step-down regulator?

hi missle..
what i call a regulator is the item that steps down the voltage to 5.1 for your rx for your rx 7.4 lipo(no the tail step down)i can see where we are all getting confused
this really doesnt matter i checked what i called the regulator and its seem fine
see my problem is that it isnt popping in flight it was on spool up where i guess it draws massive current being stalled..i think there is a issue with the speedo..ill keep you posted on this issue
i have had great help from you guys and ill send this speedo back to midland im guessing they will do nothing at all as they wernt interested last time and replaced it with gritted teeth..so ill let you know on that one also..the midand helicopter service side
its terrible having a problem like this and im going to try another speedo asap.
cheers craig simmons
