View Full Version : Power problems ?

08-03-2010, 07:14 PM
Hi to all of you.

My set up is 3 JR DS8917 HV an Align DS610 for throttle and a JR DS8900 for tail.
I also use a FBL gyro from Germany AC-3X a Spectrum 2.4G AR-9000 RX(or advise me to replace with JR 921 9CH 2.4G RX) a Scott Gray Reactor-X regulator and
a Thunder Power 2S2P 5300Mah 7.4V RX battery and finally an Aerospire MultiGov.

My heli is being repaired at this moment but as I was flying at 9ft high I switched to Idle2.
The heli reacted like crazy and screwed into ground as if I had minus pitch.
Just for the story my fail safe preset is the same as Normal in low stick position which means -4 pitch and throttle hold.

What is your opinion....
Is it entered failsafe mode due to vibration or it was a fade out due to power drain?

Finally what do you think of plugging a second battery in the RX just an old 4.8V NiMH battery to be my alternative?

And last but not least is it possible that Reactor-X was reset due to overheat or over-current?


P.S: I got from Mr Kasama the updated part for Swashplate drive arm :happyd
it's KSM10-H10 (new) and KSM10-90H05(old)

How do you go about getting the updated parts from Kasama? Do we email him or??

Email him with the serial number of you model & he will reply.

I got the update part by chance .I asked for the swashplate drive arms set like the one on every picture but he sent me the updated one.

POsts moved out of Technical Tips sticky !

I think your problem is not power supply related - the fact that it happened just when you switched to idle2 suggests that your pitch curve was different at that throttle stich position - maybe a linear curve whereas you have less negative in normal mode - if your heli is still functional try flicking conditions and seeing if pitch changes - otherwise check out you pitch curves

John how are you?

I believe it has to do with gyro vibration for that reason I will place the updated gyro
plate mount KSM10-F29 .
And may god be with us.because the gyro unit its light.

Or during changing to ID 2 I moved my stick just below middle and the heli crashed but I still cannot believe that.:arggg:,it doesn't seems correct.

Anyway I was thinking of getting also from JR that little machine that shows fade outs & frames lost of signal.

Although its been said a few times John what are your headspeeds?

Thanx Bill

HI Bill - let us know how you go !!! I run 1950 and 2050 on the Faifa and 1850 and 1950 on the nitro

During my last flight I had 1750 and 1850.
But now I will try to balance the moving parts one more tie better

Hi to all of you ...:hug:
Firstly I had increased vibes because of my stupidity and placing the piston mark of my YS-91 SR at 2o'clock while the correct is at 7 o'clock.(Influenced by my OSMAXs):arggg:
After some searching I found the correct way.
I trimmed my new frames in the tank area and finally I had my gears mess very smooth.
And last I got my Kasama Gyro Mount.
Now I have no vibes at all.:banana
I set the heli up without fuel mix and gov RPM.(Multigov)
I did some flights and its quite like a typewriter.:Bang
Temps are correct and now in the next flight I will set also the Gov.

The heli even without the Gov has a lot of power.
I hope that I will love my heli all the way from the beginning.:wow2:

I did some setting on my MultiGov at 1800 IDL1 and 1900 IDL2.
The heli is awesome.
Now the only thing I have to do it's to improve my moves.
