logo 10 with schulze 18.46 and aveox motor 36 30 1.5 ??

anyone have this setup , I just need to know a few things , got the heli running but I have a real high head speed and just need to know what yall have the DIL switches set on , I like to have wasted another main gear yesterday , Im thinking I have the timing off or something , I had a hacker 40 3P on there before and it didnt spin that fast , Last night I had 28% on mode 2 all the way across the board in gove mode and my guess was around 1100 , huh? and flew it for 2 minutes and checked the motor and esc temp , motor 75 , esc 125 F in our gym ,
Another thing , whats this about , which states in the manual and also what Chris said

It has a VERY slow startup. Best to play with it without the pinion gear attached until you get it working correctly. Also, the "low RPM / high RPM" switch will move the throttle percentage that changes RPM around depending on the pole count. For my Hacker B50-13L and whatever position I have that switch in at the moment my throttle curves are down in the 16-20% area, above 20 or so is full throttle

ok I kinda under stand that , but why do they haave low rpm and high rpm ?


thanks if some one can help . She be grounded till I here from someone , Tony

I have this motor but I'm using it with a CC Phoenix 45, which has two governor modes: Low RPM and High RPM. Initially, I used the Low RPM setting wouldn't allow enough headspeed. I now have it set to the High RPM mode and my IDL1 settings are 83% across the board which gives a headspeed of about 1550, if my tach is accurate. I set IDL2 to 87% and the headspeed went to about 1850.

hey

thanks , But I dont know if that makes a difference in the timeing , but I bet it does , after reading the manual on this V8 schulze which the manual is V7 about 4 times that Im finally kinda figureing this out , kinda , kontronics make it to easy , but now I know Im in hard timing 9Khz and I need 19 I think ??? Ill take the pinion off tonight and cry that , Tony

GGoodrum

How do you like that motor ? and what kind of flight times are you getting ?

Try low timing, the frequency is a guess - try em both and choose based on motor and ESC heating but the low setting should be fine.

The hi rpm / low RPM thing is there because the ESC is designed to be used with all motors. A hacker or Kontronik Fun series only has 2 poles, a Mega has 6 and I think Plettis may have as many as 8. If your motor is turning say 15K then the 2 pole is 30K, 4 pole 60K, 6 pole 90K etc. stokes per minute. The governor function holds pole strokes per minute is that makes sense ans those counts are all over the map depending on the motors pole count. If the range is set for a Kontronik Fun such that 80% gives a good headspeed then the Pletti would be running at 1/4 speed.

It's not high speed or low speed, it's high mode or low mode. The high and the low refering to the number of poles on the motor. High mode for a motor with 4-6 poles or more, low mode for a motor with less than 4 poles.

Hi , RMfish , this is the V8 schulze , all new , well I finaly got a hover out of it today , I read that damn book 10 times . but I ended up flipping 2 3 4 and 6 on , which 6 is 19 khz , 4 is high rpm , and 3 is gov mode , which is has 2 types of gov , standard and expert , its got to do with how good of a gyro and tail servo you have on the heli , really havent figured how to set that yet , but I have a 240 and a dig 368 JR on there , so both of those are slow , and 2 is soft start , it is nice , 1 thing I did notice , you have to open throtttle wide open before hooking up the batteries , huh? new one there for me , thats to let the controller know what 100 throttle is , then thats when you can put on the canopy and then move the throttle back , so you can use that as a safty device ,

first 3 minutes of the flight was at 60% in mode 1 gov mode , rpms were high but not as high as stated before , and also the reason why I had a high high rpm in the first place what I didnt do the throttle up before hooking up the batteries so when I ramped up in mode 1 to 60 % then that was told the esc that that was 100 % and so then I went down to 28 % to hover at a 1100 rpms , but anyway , the second flight I had a head speed , (my guess , ) of around 1500 at 60 % , maybe my pinion is to big , 13 I think , but anyway I stopped a 3 minutes and felt the motor and esc , warm ! so I went to the room and got my temp gun , and flew another 3 minutes , batteries were dead then and took a temp , 150 f for everything , batteries , esc and motor , huh? does that sound right ? Tony

I have been trying to use this motor with LiPos (4s6p E-Tec 1200s - 7200 mAh...) but it just runs too hot. I've got two RC car-type heatsinks on it and I'm using a 12V RS computer fan but two times now I've had the packs shutdown briefly, due to high heat. I've got Normal/IDL1 set to 83%, which yields just about 1500 rpm exactly. IDL2, which I haven't tried yet, except to get a tach reading, is set to 87% which is 1610 rpm. A friend told me that this headspeed setting may be too low to let this motor run most efficiently but the 13T pinion is the smallest they make, I think.

I've ordered a 36/30/2 that I'm going to try with a 17T or 18T pinion. It has a KV rating of 1460 vs 1980 for the /1.5 and 1858 for a Hacker B50-13L.

That motor(36/30/1.5) was intended for 10-12 nicad cells. 4 lithium cells is a fair amount higher voltage. You could also try 3 in series and fool with the gearing a bit.

hey , I have a 4s4p thunder power pack to put on this heli once I get everything set about right , or like I want it , but I dont know , sounds like this motor is alittle hot and might pull to many amps for the 4s4p batteries , 12 cell 2400 dump in 6 minutes , is there a some type of math to figure out the amps useing ?? a ruff amps that is .

Hey Tony,

At 1C discharge rate, any pack will take approx. an hour to discharge. So a 2400mAh pack should take 1 hour to discharge at 2400mA. To the degree it takes less, that's how many times over the base capacity you're drawing (excluding battery efficiencies).

So, if it takes 6 minutes, that's 60/6 = 10x the capacity, 10*2.4 = 24A.

Another way to think about it is what capacity would you need to go an hour? If you get 6 minutes on one pack then you'd need 60/6=10 packs to fly an hour. 10*2.4Ah = 24Ah. And if it takes you an hour to discharge, that's 24Ah/1h = 24A

In reality it may be less since the batteries don't dump as efficiently at high amps. So maybe 21 or 22A.

Useable capacity of the CP2400s is about 21-2200 mah. It does not change much with changes in current. The Logo 10 flies at around 20 amps with 12 cells.

hey , Thanks alot , so Im running to ME it seams around 1500 or more at just 50% gov mode , huh? I need another motor , this ones to hot for me , I have 2 12 cell 2400s and 1 4s4p thunderpower pack , and that would be great if I knew how to fly 3D huh? I will try the lipo tomorrow , but I bet that I get a over heat shut down with them at 50 % , huh? could I here some info on a mild motor but not weak ? thanks Tony
