Balancing a FEDA/HUMMINGBIRD
G'day guys -- wow my first post !!!
I have just joined the ranks of E-Heli flying with my new FEDA -- I have seen some guys here talking about balancing blades etc etc and was wondering exactly what this entails. I dont see apart from physically altering the blades how this can be done?
I have a slight tracking problem -- one blade is a bit higher than the other while under power in my hand, how can this be corrected?
This is my first Heli and while I am fairly competant at fixed wings this thing is a whole new ( and very addictive, I predict) adventure.
Another issue I have is with the speed controller -- on spooling up it stays green then at just about take off speed it goes red and no further throttle is forthcoming? is this a battery issue-- not enough oomph? A few cycles on the NiMh's might help?
thanks for your time and hopefully great comments -- I am sure I'll be around for a bit

If you want to balance dynamically then put a piece of tape on either blade. Run the rotor and if the vibration increases take the tape off the one blade and put some on the other. Keep adding tape until you minimise vibration.

Thanks Cliff!!!-- no wonder we al love these boards
slight problem here -- and it might just be terminology-- there appears on the FEDA there is no cyclic adjustment on the pushrods??They are a set moulded length of ABS Maybe im dense and not understanding exactly what you mean

Balancing a FEDA/HUMMINGBIRD
From the FEDA / HummingBird manual under tracking.
You can find a copy on the centuri heli website.
Hope that helps, fellow Aussie!

Blade Tracking and Lift Adjustment -If the transmitter throttle stick is at 1/2 power and the helicopter will not lift off the
ground,bend or twist the main blades slightly to increase the angle of attack of the blades and adjust both blades equally.This
will increase the blade pitch.
It is possible that after twisting or bending the blades that the blades may go out of track.When viewed from the side,there
appears to be two blades.To correct this decrease the pitch on blade A and increase the pitch on blade B until only one blade can
be seen.Attaching a small piece of colored tape to the tip of one blade will make this easier.

RE: Balancing a FEDA/HUMMINGBIRD
Heli wont take of i have a hirodbo shuttle plus i was told by the hobby shop to leave my main blades loose ie so i could move the blades with my hands? also that the tracking should be at approx 5 degrees stupid question is that 5degrees with the thicker part of the blades pointing upwards My blades are spinning so fast that i am hiding behind a wall i am sure the darn things are gonna come off BUT i aint getting no lift Regards dave England
