The volatage in the pack is about 3.78 to 3.80. I was thinking that I should also get more out of these packs then the 4-5 minutes. They are only about 2 weeks old and are the 600mah 20c packs that WOWHobbies.com sells.

Several possibilities:

1. You may have over discharged and damaged the cells. I had some 400mAh 20 packs that went south like that.

2. The batteries aren't that great. Next time try the 400mAh Oversky batteries you'll never run anything else.

3. Check everything in the drive train, gear mesh nice and free, shafts nice and straight, blades in good shape check for messed up root sections, check blade tracking, oil/check the bearings.

What pinion you running? I run 16T and WK 003 motor and get 6 minutes plus on my 4G3s.

I'd run them until the flight times get too low. I always land/shutdown before the batteries go below 3.70V by experimenting to get the time by sneaking up on it. Like fly 5 min check condition and increase accordingly to keep from over discharging the batteries.

Good Luck, Don

The motor is the oraginal wk brushless 16t that came on it. I was checking it over and decided to check the pitch. The pitch was why high, over +12 and the low end was -8 with run-up on. I turned the pitch down on the 2801 tx and now i'm getting around 6 minutes.
Who seles the Oversky batteries in the USA?

Thanks for the help!

I also get only about 4-5 min out of the 600mah 20c packs from wow. They used to last 5-6 min and I've only had them for about 1 month.

Tried a little harder this time to get a 4 blade head working.

Can only hover it for a few seconds, way too sensitive to cyclic, also cyclic affects altitude a lot.

hey guys i am sure that this has been covered but my 4g3 pitches up in FFF. From reading I think it has something to do with the bell hiller setup? Is that right? IF so then how do i fix it?? Thanks This is an amazing forum.

All helis will tend to pitch up to at least some extent in forward flight, because the front of the disk hits still air and so provides more lift than the rear.

A couple of things I've noticed, the smaller the heli is, the more noticeably it pitches up, and that FPs do it more than CPs. The FP/CP thing might be because of the typically higher headspeed on CPs, so depending on your current set up, perhaps if the headspeed was higher then pitch-up would be less noticeable, but to maintain a reasonable forward speed, you're always going to have to input constant forward cyclic.

The headspeed on my 4G3 is more or less exactly 4000rpm with the Walkera bl motor, 18t pinion and CJ power lipos, and IMO it flies just fine

I'm sure there's also the shape of the blades to consider as well, once you get a CP heli moving you can cut back on the pitch and give it just enough to maintain motion and altitude, but with an FP you can't, the blades are always trying to generate as much lift as they can for a given head speed.

To put it another way: to compensate for the extra lift you get by moving fast through the air a CP heli has 2 options, headspeed and pitch, but an FP heli only has one, headspeed.

So what causes mine and other's mSR's to tuck and die in FFF??

[mattconn24]

has anyone tried running two batteries instead of using the Y harnous and one battery for both ESCs? My tail just doesn't seem to hold and i think it is cause the main motor is pulling to many amps and not letting the tail motor get what it needs.

[livonia bob]

Too late for me to try that I have mine hard wired... But good way to check it out.. Try it and if it helps you I'll rewire mine and try it..

I think the extra weight would be a killer.

If you ditch the Y cable and hard wire the 2 escs together, and switch to micro deans for the battery, and use 20C batts, and use the 2.9g tail motor, the tail should hold.
