transmiiter settings help

[adwb]

I'm sure this must have been covered before . Any if the answers to this are there please tell me which forum and page.
1st for a arc x 400 using a futaba 6exh transmitter can I have some advice on all of the settings dual rate ;expo;throttle curve;etc.

2nd I have a problem with overreacting to control inputs and wonder if there is some trick or another transmitter or something i can do.
no matter how much i practice on a simulator or in the x400 I over compensate all the time and it is reaching the point where i want to give up.
or
should i get a ep heli that is bigger and heavy that will not be so sensitive?
if so what is recommended? do not want to spend a fortune on this. used would be good but wary of buying a "lame bird"
thanks

adwb,
Welcome to HeliTown. X400 is a one of the stable mini helis. It is more stable than Trex 450. So, you will be OK with X400. Just need to practise more. Do you use SIM? Practise with SIM and then with your heli. How long has you been flying it? Try to move the stick as little as possible and (not sure this would work for others but for me) compensate with a little correction each time to move the stick. When you correct it from the right, you know that it will go to much left so you kind of compesate it by moving the stick to the righ a little.......bit before the heli moves to far left. Does your X400 has alum head on? If yes, it can be twichy than the plastick stock head but it is still more stable than Trex450 because it's flybar. You can also play around with the expo to see if you can soften your servo throw as you like. I personally don't use the expo. YOu sound like you are already in the sky except you need more practise and it is normal for everybody.

U can try setting expo to say -25%, and setting dual rates on aileron/evalator to say 60%. This will reduce the sensitivity. I use a throttle curve of 0%, 50%, 70%, 85%, 100%, and a pitch curve of 50%, 64%, 72%, 80%, 93% to give only +ve pitch (abt 0-10 deg) (no 3D, yet).

It's really not the best idea to learn in fixed pitch mode, you'll learn some very bad habits and have to relearn them.

I set my normal to run 0%, X%, 90%, 95%, 100%. Where X equals the highest % that spooling up isn't a problem with your power plant. This assumes proper gearing for the desired HS
Normal Pitch is set up for 45%,47%,50%,75%,100%. Assuming the mechanical/swash AFR is set up to give the desired pitch range in IU with 50% stick = 0 pitch.

You certainly can use - expo to begin with and wean yourself out of expo as you progress. I don't really like dual rates as when you need the cyclic you should have it available. IE if a gust blows the heli towards something that owes you a lot of money I'd rather crash going away from it than into it. The same with pitch and head speed. One sure thing when you get in trouble there is a lot of room up above you, if you aren't bogging and are able to get there.

I totally agree, fixed pitch almost had me thinking rotary wing was the work of satan :evil: .
I had some plank flying experience and had my mind set on the same sort of learning curve :lol:.
I eventualy bit my lip and, after talking to people from the likes of Helitown etc:, decided to spend a few shillings and bought a TREX450XL and OPTIC 6 TX ( not everybodys favourite choice and cheap compared with many setups I know).
BUT.I built it, managed to get the mechanical setup as good as humanly possible ( I have dumbed down my cyclics using inner holes in servo horns ), played around with the TX settings when I had a couple of minutes at work :wink: and, low and behold, am now up to almost a stable tail in :o .Build took me two weeks of weekend and evening hours that I could find, hover has taken me two months :roll: .I figure I aint gonna 3D until NEXT christmas :lol:.
I am currently having a ball but You GOTTA stick to it 8)
And have I crashed :?: well a couple of times, but crashing fixed wing can cost you a load more :(
