Maidened the Trioblin 570 today !!!

[cjm180]

thanks for the replies.

I fly my 600l on 12s 3.3 turnigy blues. i get around 6:30 and the packs sit at rest after that flight at around 3.7v. so i consider them 80% used at that.

As i have gone for more expensive packs for the kse (thought i would try the SAB batteries) i only have one set for now. The main reason i went for these is i know they are for this heli. so now i can see the clearances and may try a different brand if the SAB's do not perform as well.

Anyways i am after flight time with this heli! The feel of it in that initial flight tells me its got alot of capacity at its current head speed. So if i can drop 50 or 100rpm, coupled with the current current drain on the packs, i am confident i can go for 7 or even 8 mins. Obviously i have not pushed it to my max ability (not much more to go lol) so we will see at that point. but if those times hold up i am very impressed.

Ok i will drop the tail gain a bit. the dial i have it assigned to on the 14sg jumps i thing 4 or 6%. i checked it against the axon diagnose page and its almost tx travel to axon travel. So the percentage shown in the tx matches pretty much what the diagnose page says. i have only flown it at quite a small field where i live. in a few weeks i will take it down the club and get some more observations at a bigger field.

i will also knock the tail agility down a little also. Also the heli took off a bit sharpish up when i hit rescue. i know there is a setting in the software to tone that down. As long as it climbs i am happy. it doesnt need to rocket off.

One thing i did notice that i didnt say in the last post, was the motor was hot when i finished that pack. i mean, it was noticebly hotter than the 600l. you could hold ya hand on it but it would be enough for u to let go after 30 odd seconds.

The PWM and timing is set up as per the Xnova website. ummm

I would think 7 or 8 minutes should be possible if you can run a headspeed around 1700-1800, just as a rough guess. I converted two of my 600 12s helis to 6s so that I could share packs with the others. On 12s I was generally at about 2000 headspeed and using 2600/3000 mah packs I was getting maybe a bit over 6 minutes. Now I am running both of them at about 1750 ish and still get 6 minutes but on only a single 4000mah 6s pack. One of them (Beam Avantgarde) is really light though, more like 550 weight range.

Try and video the flight next time pls. Id love to see it in action.

Setting a higher PWM can reduce motor temp a little, at the expense of the ESC running a bit hotter. I always use the maximum PWM that my ESC supports.

Projected flight times sound very good especially for a tri-blade setup which tends to hit flight times a fair bit.

Hey

Managed to take the G570 down to the field for the first time today, thought i would feedback a few observations!

Its the first time i have been at the field for around 7 to 8 weeks, so rusty to say the least!

I got 5 packs on the 600l to shake some of it off lol.

So during some pre flight checks, i picked the heli up by a blade grip and noticed a little play up and down. Had a good look over and noticed the play was between the head and the main shaft. So i tightened the two bolts, the jesus bolt and the other bolt to clamp it. Not sure why these were loose. The jesus bolts uses a nylock nut, and i had loctited the other one. Something to keep an eye on!

One thing i had done before this flight is knock down the agility on the head and tail down a few points. This was largely based on the initial hovers. Its also the first setting to be changed from the stock settings in the axon (except gains).

The plan was today to work on the gain settings some more. Last time i flew it i felt i had got the tail to a good starting place. Only towards the end of the flight i tried the rescue function, which ended in a severe tail wag.

Upon lift off, the tail had a very flight wag. more of a twitch to be fair. So i knocked the gain down one point on the dial. All was well. So i continued on into some circuits. I also knocked down the climb rate in rescue, which is now a lot better.

Now i have had a chance to do some more stuff than hovering, it struck me how used i have got to a particular shape of heli, the 600, especially in different orientations. With its pod a boom, and the fact the boom is parallel to the skids. The goblin cuts a very different shape in the sky. Its gonna take some getting used to. All subtle differences, but differences none the less.

As reported before, the tail authority is fantastic. But for my current flying style i found it to perform a lot faster than the head. For example, in a banked turn, the goblin requires a lot less tain input than how the 600l is setup. So thats something i need to get better. The tail is a little quick. I am not sure if i like it that fast. but i definitely need to speed up the head first and see where it is. I suspect i should knock up the agility setting for the head again.

The other obvious thing is how animated the heli / fbl controller feels. Its probably too animated for my liking, but one thing it does do is highlight very clearly what inputs you are using. Which is good as advance my turns / stall turns / loops. It is very clear which surface is lacking in a maneuver. Which is good.

I cant level this as a downside, i think i have the 600l setup so slow and docile on the gpro. I reckon as funds come available i may buy another axon for the 600. Or maybe even try and pick up a cheap 3sx.

Really happy with it so far. Although it feels a lot different to the 600 and anything i have flown before, it looks great in the sky and feels very crisp. So i really need to get another couple of packs. So i can get a few flights on it in succession.

Ps, i hate fighting the canopy!

I took the camera with me today, but some planks turned up so felt a bit stupid lol. Will get some next time for sure!

She looks great Craig.
Have you have tried adding more exponential on the tail? Expo can calm the initial response and give you a more balanced feel.

I think that is exactly what I need to do. I do also feel tho the head response is really sluggish. Not from the control loop, just in my inputs. I did dial some expo in for aileron and elevator, I will look to reduce those.

Also on the collective, it seems a little weak. For example coming out of a turn and the heli drops because of the wind, it seems to take a big collective input to correct it. I am running a linear pitch curve.

I guess I need to look at the castle logs and make sure my head speed is reasonably constant. I am running a lower head speed, between 2100 and 2200rpm. If the HS is steady then maybe increase the pitch? I am running +-12deg
