total loss of performance HELP!

[lrosm]

Hi there,

i brought a Bixler2 in July of last year & from July to Oct I was flying it using the stock motor & a 2200 3C & 1300 3C battery with no issues at all.

i had to lay the plane up for four months as I was working away.  On returning, i have seen a total loss of performance on the plane.  at first i thought it was just the trim as I put some FPV gear on it (just a fatshark Tx & camera / Suppo OSD) & had trouble flying.  I thought it was trim.

I am now not convinced.  I have tried both batteries & I just am getting no "ummph" at all.  Even at take off, it used to strain to fly when I held the plane up at full power, now I feel no real pull & when throwing it, i am lucky if I can get it into the air before it stalls.  it is like the motor is at half power!

now saying that, I do have a new transmitter a DX6i....now could it be that my throttle, on the tx even at full power, is actually not putting out full power on my motor?  could it be a config issue.

i just cannot see how two batteries & or my motor can lose so much power?  help!!  my poor bixler is feeling very beat up with the amount of nose dives & wing tip stalls these past two days!!

cheers,

lrosm

Have you got the prop on the right way round? The numbers should point forwards.

The stock Bixler 2 motor is very hit or miss.. mostly miss it seems.  My one is going fine, but FlyBoySee's wasn't working out of the box, and there's hilarious video of Keukpa attempting to launch his full whack and it nosing into the ground repeatedly.  So it might have gone kaput.

Alternatives are as iPeel said: Prop round the wrong way.  Or as I had the other week flying my Falcon and finding it had now Oomph, if you've got any space around the shaft and the prop - i.e you are missing the ring that would fit in there, that causes a real loss of performance

" new transmitter "

I wonder if you need to recalibrate the esc to the transmitter ???

hi ipeel,  unless my son played around with the prop it should be the right way round! just checked for numbers & could not see any? it is the stock bixler prop.

i do have a spare motor so could try mounting that i guess.  its just all very strange but i guess that is FPV flying all round!!

hi there,

my esc again is stock from HK.  it is a new TX.  so how would I do that?
i have to admit i was thinking something along these lines that my "full up" on my tx throttle wasn't actually giving me full motor power.

[Loopdreams]

This is pretty much the same for most ESCs.

TAKE THE PROP OFF.

Power the plane on with the throttle at full, hear a beep or a couple of beeps and then lower the throttle to minimum, hear another beeps or two.

Does sound like an ESC calibration is in order.

hi there

ok did that, i had the power on full, then connected the batt.
the motor did NOT spin at all.

i then lowered the power to minimum.  it beeped.  then on raising the power, the motor spun.
so i guess that is my ESC calibrated. now it is testing it!

[lrosm]

oh and i found the numbers!

[lrosm]

i guess the proof will be in the pudding!
i will take her back up again later & see how she goes with this calibration!!

[CurryKitten]

Oops, missed the bit about the new tx. Sounds like you got it calibrated ok. You'll probably be able to tell if its made a diff just by holding the plane as if you were about to throw it and throttling up. See if it "pulls"

[lrosm]

hi all

cheers for the swift replies once again!!  it really is a learning curve!!!

cheers

[lrosm]

hi all,

just had the plane up for a test.....no joy!  i am completely stumped.  on take off, there seemed to be some "pull" to leave my hand (maybe wishful thinking) but even at full power it was grass cutting then if i was lucky to keep level i could slowly very slowly gain a bit of height.

i have a new motor that i will fit & try again.

i am Still wondering if i did my ESC programming correctly! 

i will try that again too!

cheers.

Did you check the prop?

I've done this enough to know what way to put the props on, but absent mindedly I still did it wrong a few weeks back and  it took me a week to realise what I'd done.
