He is probably using the 2801tx and that is how he is able to turn down the swash settings.

I want to be able to do small circuits and funnels in a small area and right now it covers way too much ground too quickly for that. Woohoo!!!

just put 2 pack (stock and the 400mah 20c) and the tail held very well.. just as good as the stock setup...doing some hover and pitch pump in the kitchen but then.. im not the right pilot to test the capability of the heli, but tail held great.. the CF rod just feel stronger and stiffer.

lighter, stronger and the guide can be removed.

my motor/esc become so hot burning hot

i think the main gear would need a shim to make thing run abit smoother, someone else noticed that? things doesnt feel totaly smooth in the drivetrain and that seem to come from the main gear.
if i lower main gear a hair.. things feel much better but still not perfectly smooth.. not sure whats up there.. and since we have no way to see how the gears mesh, it doesnt make things any easier..

Check your pinion gear Dark. My stock pinion was not perfect. It had a couple of nicks and was not at the right height to find a smooth spot. After I changed it out to the "perfect" 16t the drivetrain is smooth as silk.

I suspect it was 2801pro, swash mix from -70 to -60 or less for PIT.

The stock -05 motor does that, put in an -03 motor and the heli will have better performance and the motor will run cooler.

The esc getting hot is why I tried different locations away from the rx.

LMK what you come up with cus with your settings, the heli sucks to the ground when I land it. Too much neg pitch I think. Did you keep the pitch at 70 and just lower the other 2 or did you lower all 3 to 60?

I just lowered the other two. If your heli is sucking to ground at landing you need to change your pitch curve in Norm mode. You should only have about 5* negative pitch at bottom stick and about 2-3* negative at 1/4 stick and zero pitch at mid-stick, 5-6* positive at 3/4 (hover) stick and 11* at the top. I am going to fly with buildem336 this weekend and he is going to set my 4G6 to his liking. Should be interesting.

No not the PIT. I reduced the Ail & Ele to 60% to calm down the cyclic response a bit.

Here are a couple of pics of my 2s 4G6. It is very, very powerful.

checked the pinion and it seem "OK" and well lined up with the main gear.
the more i run it the more it seem to become smooth, even put some grease on the gears.. made a big difference i think!

before i use the grease i had drop the gyro gain value down to 65(out of the box)
instead of the defasult value that was set to 75.. i had some very small/fast wags
now since i added the grease. ive put back the gain to 75 and no more wag
things run much more smoother
idk if the grease really helped or if the gear did breakin in? but this is "smooth" now.. still run burning hot though
ill check the temp next flights.

does the 4G6 motor work well in the 4G3? i would just swap them.

Must be because you put the ESC + connectors up on top of the RX, I can see your canopy is sitting higher than mine.

I tried putting the esc down on the side of the battery cage, did keep it a little cooler, but now have it back where it was originally, on the side of the rx, but used thicker tape to keep heat and vibration away from the rx. Needing to take the skids off a lot to work on the tail gear makes putting the rx on the battery cage a pain.

i didnt meant tight over the the heli.. i meant tight in the bottom holes.
nothing to worry about really.
no problem with the ESC on top, it doesnt toutch the canopy
and the canopy been like that OTB.
mb my groomets are a little off? anyways.. better be tight then loosy i guess

I see. I've used D/R and switches. In Ele and Ail switches being up I have 35% expo +100% D/R and when then are down I have 60% for expo and 80% D/R. More or less same thing as you but I can decide upon which I want at the spot. BTW - Just now tried to flick those switches in flight and failed. LOL

Oh, - there is another thing I've done for throttle - added a mix for +20% (which read really -20%) on spare (gear) switch. So when it is down I have lower HS in all three modes (Normal, Idle Up 1 & 2).

[Dark-Angel]

hey DK, you were absolutly right about the pinion, disengaged the motor off the main gear and things was all smooth.

i though my motor/esc connectors was comming hot due to the fact that they were stacked over the ESC which become very hot.

i moved the ESC on the battery tray and put the connectors as far as posible of anything. ran a pack.. connector were hot again, so i went ahead and shortened the .8mm bullet connectors and installed them on the motor/ESC.

and wow, what a difference, head speed went up by a good amount.. funny thing is the the GF even noticed it and say mid flight "its me or your heli as more power than before?" i had not told her anything about the mod
lost 0.8g in the process
the .8mm bullet will only be warm after the flight
more HS, more punch, less heat, less weight
very nice mod!

[Dark-Angel]

just tryed the 400 mah 20c pack and it has some more power
but the connectors become hotter than i though, but not as hot as the stock one

looks cleaner and less bulky too

87.75g instead of 88.6g

Yes, the -05 motor on the 4G3 can run with a smaller pinion. Whatever they did to the -05 motor it runs faster with less load, since it's only running the main blades on the G3 it's acts like the -03 motor with an extra couple of teeth. Still gets really hot on the G3 though.

I might get a second G6 and give up on the G3. There's just no consistancy, can work to get the tail holding and then the next day it's not. Still got a few more things to try before I give up...
