no lift??

hi guys
well have finished all repairs to 450 heli but now it wont lift off?? any ideas
Colin

First guess would be pitch curve Colin, is it going into poss pitch?

I dont know quite what you mean mark, it spool up but just sits there !!
Colin

check you pitch range, using a pitch gauge and as mark said first, ie adjusting the curve to suit.

-2 at zero stick
5 at mid stick
8 at max stick
remember to disconnect the speed motor when you do this. if you pitch range

just be careful colin in case it's in neg pitch does it push itself into the ground when you throttle up & lift slightly when you throttle down if it does you may have the pitch reversed, failing that can you see the blades moving when you open the throttle with no motor on the trailing edges of the blades should move down for pos pitch & up for neg pitch

sorry about the broken email ! was trying to do too many things in one!

if you still have a problem Colin, bring it to the field, will have a look at it for you. Should be there from Friday weather permitting.

Most important words in all of the above are be careful. If you're unsure get someone else with more experience to suss it out for you Colin As per Zaidy's offer

ok all
l will check pitch first, without motor plugged in.

OH NO..!!!

I was wondering if he had been kicked out of his own home, and is being forced to seek refuge at the field!

Andy

he has to make up for the lost time, it will be nice to see him occasionally

Perhaps we should consider painting some parking spots in the pits, and have one especially reserved for Zaidy?

LMAO.. You are right Rich, I have to make up for lost time, which wouldn't take very long !! 7 days of 10am till late ish should do it !

Andy, I think that parking spot idea is a great one.

See soon

trouble with the parking lots there all taken, it's the long grass for you matey

Oh I see.

I guess you wouldn't mind if I use yours during the week then while you you are busy at work

I love the way this has stayed on topic to help Colin out lol,

Yeah!
lol
Im pretty sure zaidy could help you out

I'm away for a coulpe of weeks soon, however you are welcome to the short grass spaces until the real flyers arrive as you would of flown out by then

Thanks Rich, that will do as a start and I will consider handing the space back when you come back from you holidays.

Ok checked with pitch gauge
-12 at bottom stick
-6 at mid stick
=1 at top stick
so if I alter my linkages for one setting, how do I set each one
c
ps this is in normal mode

the minus 6 at mid stick is incorrect, not 100% but it needs to be positive pitch check you manual.

You'll have to use the transmitters end point adjustment & pitch curves if it has them

there all way out -12 will just slam the heli into the deck if you drop the throttle stick

As Zaid says for normal -2 +5 +8

Heli will proberbly be capable of -12 to +12, use a pich curve in the TX along with you pitch gadge to alter, you may have 3 points or 5 depending on TX

M

Right that is way out!
Start with
check servos are @90 deg to links (under power)
then
check your links are the correct length as per manual
so the end results
swash plate is level at mid stick

then you play with you pitch curves on your tx.
Ps for ccpm to work correctly, all three servos have to be the same

I hope this helps

hi Zaidy
all three servos are 90 at mid stick and all new Tunigy's TG9e
servo rods spot on
links rods spot on
swash spot on
VRB knob at 12 o'clock
should throttle trim be at zero or centered? on tx
I have 5 points on my pitch curve ( in % ) they are
ep0 38%
1 54%
2 70%
3 85%
4 100%

colin

throttle stick & trims mid point as they are linked together electronically
