I hope i'm writing in the correct section.

After two successful experiments (take a look, if you wish: https://intofpv.com/t-inav-fine-tuning-a...-questions) now i feel myself ready for something else.
I love tricopters and the goodness of the latest INAV release convinced me to face another challenge.
I build drones since last summer, 13 months ago. I'm happy of myself i learned a lot.

So this is the frame. Everyone knows it, i guess.


I have some questions before ordering the parts i will need.

1) 5" propellers and the suggested motors are Emax RS2205 2205 2300KV, in the descriptions they talk about 2204/2205/2206/2306 motors. What are, in your opinion, the best choices for a 4S Lion pack? I want flight time, not speed. 

2) A 4in1 ESC, 25A, will do the job or i want to choose three separate esc?

3) About the rear tilting motor... anyone has ever tried a counter-rotating motor with balanced thrust?

Any tip or suggestion will be really appreciated

Just know that tri-copters are a very different thing than quads, and MUCH more difficult.

I think they are neat, but I don't feel up to diving into that kind of headache. Still trying to wrap my head around how quads work.

I would recommend the TriCopter forum on RCG:
https://www.rcgroups.com/tricopter-drones-937/

They will probably be able to help answer your questions specifically on tri-copters.

2203/2204 is totaly fine for flighttime. a few buddies fly the t-motor 2203.5 on 5inch and 7inch for flighttime, these are nice

4in1 is fine, 3 separate ones are fine too.

i did a 65mm 1s tricopter, it flew and worked -somehow-. my tilt mechanic was selfmade and gave vibration issue, not sire but maybe the servo i used was a bit to slow. its waiting in a box for some love :-) a new mechanic for the servo and a better servo is still placed to attache.
with a bought frame like the nice one from rcexplorer above, you wont come into troubles :-)

:tricopters are nice :-) specialy for efficiency, you will get great flighttimes on the right lipo :-)

First, thank you for your interest.

i NEVER had a flying RC stuff, i started 13 months ago building an Eachine kit.
During the work i learned a lot of things, i love headaches when the result is satisfying! I never thought i could have TWO small UAVs with GPS, compass and all the right stuff to make them able to autonomous flying. More, i build them by myself!

I'm doing some experiments with a pair of 4S Lion: one 3000, the other 3500mah. A lot of weight, a lot of flight time.

if you are very focused on flighttime, the 7inch tricopter would be even better.

to figure out the most efficiency battery combination, ecalc.ch is a nice source.

If you didn't already find them then you should also check out David Windestal's website and YouTube channel...

Just be aware that not a lot of people fly tricopters so there probably won't be a huge amount of support out there if you run into issues.
