Days starts to be shorter. It is clearly seen up north. After work when I come home, I do not have much time to fly. Maybe I need to have some time in the morning, before work.

Well, I started to think of retuning my room flyer - 4G6. If flies, but can be done better. At least tail gyro should be replaced as well as blades. As a next stage, I will try to start flying it inverted. Pretty tough in a room, I would say. I need not pass the moment when it is still possible to fly outside and to get some practice in flips in confined space. 4G6 is very unpowerful and exact throttle management is required, otherwise motor bogs and welcome several hours of setup.

What are your plans for indoor flying, if any?

I like flying outside in the coolness of Fall and the cold crispness of winter when the air is clean and fresh and alive. And if your little baby fingers get cold in the wintertime--- then you are a big baby Just kidding-- kinda, sorta, not really--- too each his own

About freezing fingers.

When I was young
Much younger then today

I dealt with white water kayaking. And white water means cold water, very cold. So at our club, our coaches advised not to wear any hands protection at winter time to get used to cold. Well, it helped at spring time, when rivers just got rid of ice and we had to swim in that damn cold conditions.

As of winter flying - no light time. You get to work when it yet dark and come home when it is already dark. Despite cold - just dark.

Its sunny and 90 here in Seattle. Dark days of winter seem so far away. Its depressing to even think about it. I was flying at 9am this morning. It was sunny and 70 at that hour. Life is good, but its too short. Like summer in Seattle.

I have a 4G6 and frankly it is a piece of crap. It is a runny piece of crap and should not be permitted to enter the Americas..
Don't waste money on crap that will make time pass more easily,,save money and get the hell out of there !!

Setup is everything, All my heli's can fly far better than I can pilot them

I would disagree that 4G6 is crap. To me it is nice flyer, with limited capabilities die to its size for sure, but I would not say it is crap.

That was my last outdoor flight, while back ago:

Well I can do that with my trex 450 Raptor 50 and both my Min Air gassers
[good flying by the way] but my 4G6 has never performed well for me.
I still say move south far enough so you can set up my 4G6 for me as mine is still a piece of crap.

Thanks. For sure bigger helis can do more, not surprisingly. But they cannot fly in a room. 4G6 can. And this is the smallest CP in the world. My goal for this winter is humble - just to fly 4G6 inverted in a room. Could not do this stable (only sporadic) last winter, maybe upcoming one will be better.

I agree - it is all in setup. The smaller heli - the more critical setup. On 4G6 I had even to balance motor itself.

Wow,,so I take it you have spent alot of time getting that 4G6 that airworthy. I sure would like to know some of your secrets.
I have had my 4G6 flying very well for 15% of the time and 85% fair to poor. When it was flying well it was a dream come true. Land it ,stick in another lipo then she would fly like crap for some reason.
Random vibration issues but amazingly the tail ,tail gears and gyro work very well.
Share any thoughts about setup?

Here is my room fly machine. It's the one sitting on the head of a larger machine.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I was at the LHS and almost bought an MSR and give up on the 4G6
but something stops me from buying a fixed pitch heli. I have never owned a fixed pitch and think it would be a step backwards.
Maybe I'm a snob!

Turboomni, really no secrets.

Some tips:
- I use HP08-2 motor. I balanced bell on it, getting no vibs.
- Some blades are good, some blades badly balances. Looks like blades from Terence are OK.
- Careful balancing of everything, using magnetic balancer from XTreme - that tiny one.
- Oiling of bearings by Scorpion oil.
- I use upper mixing arms from Gaui.
- Gyro should be strapped to frame pretty tightly.
- Tail servo is crap and does not last long
- 70 duro dampeners from clubheli.

I use 18T pinion, I tried 20T, but could not get vibes. I have heard that there is upgrade of blade holders. They help in blades fluttering. I did not try them.

That's pretty much it. Do not hesitate to ask if you have questions.

Once it is setup, it flies very consistently. I flew for 2-3 months 2-3 flights a day no problem, unless I crashed it two times in couple of days. Now I am out of good blades, tail servo. So I need to redo it.

Turboomni, really now secrets.
Well they are to me LOL!! This has been the most elusive to setup helicopter I have ever owned. The very first generation Shogun which came out before the Trex 450 was easier to setup than this piece of poop. Well I'm hoping it can change from poop to heli.
My motor is the wow hobbies upgrade inrunner motor not the one you have.
What balancer do you speak of>?
I went all plastic as the metal head it came with was junk with a hole to big for the mainshaft from the factory. Bladegrips too.
Mixing arms I modified the metal ones to work with the plastic then went with the plastic mixing arms.
My tail servo still works fine as does the gyro.
I tried sanding down the spindle to squish the dampeners abit ,didnt help. I also put washers there ,,no help.
So 4 things stand out. The balancer,the motor [maybe] and the harder dampeners and the mixing arms.
My biggest problem is random vibration/shudder of the heli. Actually that is my only problem.
What balancer do you speak of?
Thanks

My room flyer?

CB100.
It's double brushless with, the HB06 main motor, and a 2.5g tail.
I have 9 batteries for it, and a harness to charge 3 at a time (it basically takes the 3 1s batteries, and treats them like 1 - 3s battery).
That means that flight sessions are only limited by my endurance.
If I fly out the first 3, they go on the charger, and I start flying the second set of 3. By the time I'm done with those, the first set is charged again. But I still have another set in reserve. So I fly those, and let the first set "rest".

I "could" fly all day if I wanted to.

I also have an old 4#3 that has the 4#3b head on it.
I've found that with some minimal modifying, I can put that on the CB100, and turn it into a 4#3B. That's coming up.
But so far, I'm still loving the CB100. Great flying little heli.

someone conquer the 4#3B
Our boxer "Buddy" has attempted to conquer / bite it.

He knocked it out of the air once, no damage to him or the heli.

Those things are pretty crash (dog?) resistant.

I managed to slam my CB100 into the wall hard enough to break one of the straps on the battery holder. I found the hard way that a CB100 will gain a respectable amount of forward speed under the right conditions.
And yes, walls are harder than helis. hahaha!
Even at that though, the damage was very minor, and the heli is still flyable as is. I'm going to fix it, but only because I need to order some other parts anyway.

Since I need to order a new battery hanger anyway, I'm going to order the 4#3B frame. As near as I can tell, the major difference between the CB100 & 4#3B frame is the anti-rotation bracket. If I put the 4#3B frame in, and keep the the CB100 bracket on the servo tray, I "should" be able to go back & forth between them fairly easily by just swapping the head. It will just have 2 anti rotation brackets.

I'll know for sure soon enough.

Turboomni:
Balancer is:
https://clubheli.3dcartstores.com/B...4G3_p_2439.html

with

https://clubheli.3dcartstores.com/M...ver_p_2442.html

This is magenetic balancer. Very nice. It can be found in a number of places.

I also have plastic head and plastic grips. At least they stay true or break. I guess I know what's going on with your random vibrations. Stock dampeners are not good. I use these ones:

https://clubheli.3dcartstores.com/C...ter_p_2414.html

or

https://clubheli.3dcartstores.com/C...ter_p_2415.html

I do not remember exactly which ones I use, but they are both nice. I tried to sand feathering shaft before, but it did not help. You can also shim feathering to get tight but rotation free blade grips. And I keep oiling quite often all bearings by Scorpion oil. The problem with oiling is that I spoiled elev servo. Oil went inside and I had to replace it. I put a bit of scotch tape on servo now as protection from oil drops.

I also stighten main shaft right on heli. Spool it up a bit and try to touch it by marker. If there is mark on one side, just bent it. It is butter made, so hands are fine. A bit of effort is required.

I did not try yet 'Stay true' head from Dkfuji at wowhobbies. Maybe this head will be better.

Btw, there should be no vibs on spool down on low speed. If there are, probably shaft or blades are not balanced.

As of motor, try to stay away from HP08-2 which is everywhere now. People report bad things of it. Not that bad, but not that good. It was last batch, which was not that good. Mine is from previous one, hopefully it is better. I do not want to experiement for $50. There are rumors that HP09 motor will be released soon.

Once again - stock dampeners are no good at all. Too soft and too small to sit tight in a head.

I run about 4100 HS. It is about because I did not tach for a long time.

Well, smaller heli - more demanding setup. Good luck!
