Nearly every bird can be set up.
I did set up an old ECO 8 electric ( was a bit complicated ) but even this one performs now approx like my big F3C bird, at least for some training.
There is tons of threads here on setup.
From my point F3C is 90% training ( at least when you are beginner )
Sticktime and reliability are the main points.
Orientation is everything.
If you still have problems there you can get rid of them even with a micro indoors ( saves some fuel )
If you really want to compete you will need a B machine, in case something fails ( Crashes are very uncommon in this F3C )
You can use a standard 3d setup on your machine and hover the figures to get some feeling for orientation and position first.
A squirrly model will show your steering imprecisions by magnifying them. So for training in the beginning it iis not a bad idea at all.
Before investing a lot, just fly through the figures to get some feeling for them. Every one has some difficulties build into it you have to understand.
Good idea would be to read the FAI F3C judges guide.
If you want to fly more precise the steps are ( from my humble point of view )
- ADJUST CG ( on this one with half tank )
- setup flybar mix to around 75% and delta to zero.
- check hover behaviour on a gusty day and adjust some flybar weights ( and might be paddle length/weight/profile later )
- adjust rotor RPM ( Governor? ) very exact to find a "sweet spot" - that depends on a lot of factors and 50 RPM is a difference so take your time
- mix phasing out of the head until no intermix
- check FF behavior, probably add/remove/move fin size
- check loop behaviour, add/remove mixes
- same for roll behaviour right/left
But to put it into perspective
A good pilot will win a local F3C club competition with a imprecise 3d beater.
in competition you have to perform spot on, regardless of material and condition.
Sun disturbing? Wind in wrong direction? Rain? Nerves wrecked? Bad hangover? Little cold?
F3C is not only the model, it is mostly training and performing spot on.
To give You a feeling, just put a two comes somewhere and hover straight lines forward and backward between them at a constant speed
