500 3D notor and pinion set ups.

[Airboss]

what set up do you useand hows it flying?my set up is FP6s5000,CChv85,Align600L motor,17 pinion/herringbone.just built and tested today it gave 2450rpm 5min flight.what do you think?

[nono]

My setup:

Motor: OBL 43/11-30H 1050 kV
lipo: 6s 4900 FP
pinion : 20


I set my controller in gov mode and i have 1900 rpm.
I flight about 13 min. ( soft flight, NOT 3D ) and I put in my battery 3908 mAh.


Bye

airboss, 2450 is a bit high on the head, aim for 2300, which give a really nice feel in all 3D, esp on the larger blades

[Airboss]

thanks eyon,we will be testing some other setups next weekend,heli flys great at 2400 its going to be hard to lower setting,how do you guys keep the motors cool,mine needs airflow.and i will not cut holes in the canopy,its too pretty.

[Airboss]

just got the Z30 1100 Kv motor and will be using 6s3700 lipo.what pinion for hard flight will work best?18 20 22 ?am using 515mm Mscomp rotor.

airboss, for that motor for 3D you will want either a 22 tooth or 23 tooth. Get both and find the feel you want.

:)

[Airboss]

thanks oicu812,i tested with the 21 pinion this weekend and the heli was very smooth but a tad under powered,so hopefully by next week i will have a 22 or 23 pinion.i really enjoy flying this heli,in a world that seems full of trexs and their clones.

I'm running the same setup with a Jazz 80. I get 2450 at 80% throttle. I have dialed it down to 2250. My opinion is the 22T or 23T is a little much and harder on the battery. Of course, results may vary.

I'm seriously thinking about trying a tango 45-10 on 8s 3700 FP stick packs. anyone know if the necessary gearing is available? This should top the motor out at just under 30K rpm... Otherwise I'll get the new hacker a40-8s 8 pole 1100kv motor. A friend at the field is using this setup on his 500 3D on 6s 5000's and it is very impressive.

The Tango 45-10 on 6S with a 22t pinion is a great setup for all but the most demanding pilots. The reliability of the motor is insane, and certainly worth the extra cash. On 8S, an 18t pinion run at 85% throttle gain should be OK. It will also put the motor in it's most efficient shaft RPM (~30,000).

The A40 8-pole is in the testing phase, but is certainly producing power. We just need to find the optimal setup.

[buster1]

is the tango 45-10 producing good aggressive 3D performance and what duration flight times are you getting,
Thank you,
Jeff

i have seen the new hacker on caseyholmes heli,and it is a powerhouse.but i think with 22th pinion this Z30 will outperform the hacker.we will have them side by side next weekend.i was getting 5m hard flight and recharge 2800ma into 6s3700FP.

we here at Flightpower UK have been testing the A40-8P-8L and its compeltly ballistic. Mod 05 with a 21T pinion on 500mm blades turns at 2500, so im going to go up to 550mm blades and aim for a slightly crisper feel at 2300rpm. 13 degrees of pitch and the motor copes with ease. We're just testing ESCs to see what is the best at the moment, but 6s 5000 EVO25 looks to be an awesome pack, with a good 6 or 7 mins duration.

Ill keep you updated

Ian,

So the 5000 pack does not feel to heavy throughout maneuvers in this particular heli? I noticed in your model line you show 4350s' , what kind of feel and flight time where you getting with those? Also as far as room under pinion, can you elaborate on the room available with the 5000 packs? I ask all this as I noticed teh 4900s do not fit with proper cg, you can use them but you will have pack a mm or 2 tops away from pinion and still be nose heavy as well, which I do not care for.

[Eyon]

Hey Shawn,

The 5000 packs have a good 1/2" room under the pinion, its more than enough to be comfortable. the 4350 cells give a good 5 mins and plenty of power, where as the 5000s give 6 mins with just a little more (marginal because of a 4oz weight gain which counteracts better voltage stability). that said i will have to put more time into the 5000 packs before i make a proper jugement.

Balance wise, it seems to be fine, both using the balance on the flybar, and hold the heli horizontal methods, it seems to be about perfect. its a longer pack than the 4900, so the weight shifts back a bit, and even if it doesnt quite balance, just move the whole pack back a bit, its not exactly the battery tray is small!!

Ian

[OICU812]

Hey Ian please keep us updated on your pack trials, I would surely appreciate it as I am sure others would as well. I for one am trying to make a very educated decision on packs, I really like the light feel of the 3700s but they taper off a tad and of course your flight time is limited with them. For a 4 minute whoop up they are awesome but I'd like to see 4:30 to 5mins for sure.

[fogger]

Rumor has it there is a A40 8 pole 1300kv also in testing. This may be another sicko option for 6s... Higher KV = more efficiency, right? (we're worse than the ladies wrt the rumor mill in this hobby ;) )

-Fog

[Eyon]

yes, the 8 pole 8 turn, 1300kV motor is what im running, and it is avaliable in the UK.

Shawn, i will keep testing. my first flights i had with the L500, i had the 3700 6s, and i agree, very light, but it really suffered in duration. i can handle 5 mins, but not 4! the 4350s fit great, and give a good balance between duration and weight, and the 5000s are just a bit bigger and you get a bit more duration and simular power. I'm going to order some 550mm blades today (been running 500mms, which are just too small and require a lot more work on the heli with the pitch) so i will feedback to you all when i get some time in on them, and decide on pinion and my favorite lipo pack.

Saying that, ive also been running some 6s 4900 EVO20NF long format cells (3 high 2 long) which look to be good, but havent got the grunt of the EVO25 cells.

Ian

[OICU812]

Right on Ian this is great stuff. Not many peeps got this motor you have man. When you have some time on it and more on the packs etc please post your setup on the setup thread here as it sounds like you are getting it dialed in and rockin'! :D

Are you running the Mod.5 (212) main gear with 18tooth HB pinion or the Mod.7 (153) with 13T HB Pinion with that 1300kv Hacker?

[Eyon]

mod 5 with a 21T pinion :D and i have only stripped two main gears when i forgot to tighten up the collet at the top of the bearing and when i landed the rotor head pushed the main gear out of the pinion, my stupid fault. the other happened when i crashed inverted.

10:1 gear ratio, on the 500 blades its 2500 on the head, hence why im getting 550s! 550 at 2300 is what im aiming for, and ive flown another 500 with this and it felt so crisp

Ian

[Eyon]

oh yeah forgot to say, the 8 pole 10 turn is great for mod 7, but too slow revving for mod 5, where as the 8 turn can be used on both. Of course, as a sport/scale machine, 10 turn can be used on mod5, but dont expect a 3D headspeed

[Foamy Love]

So how did it go with the 550 blades?

[Eyon]

awesome, check this thread http://www.helifreak.com/showthread.php?t=48009

[Foamy Love]

Thanks. I'll be running a V-Bar so I should have no problem seeing 2300 if I went with the A40 8P 8L over the Z50 which is impossible to find.
