Today's servos and especially socalled high voltage servos typically have a very high power consumption. When using Futaba BLS 451 servos for example these are very modest. Savox 1258/Align DS610 are much more demanding, one alone taking up to 15Amps peak for the instance of a second. And for very extreme example take high voltage Savox servos SB-2271SG HV. They demand up to 27Amps (1 Servo!) peak which you can see when measure the power consumption with an oscilloscope.<br />

===MICROBEAST/MICROBEAST PLUS with single Spektrum remote satelite on large helis===

===MICROBEAST/MICROBEAST PLUS with single Spektrum remote satelite on large helis=== <!--T:60-->

''Why is using a single Spektrum remote satelite directly connected to MICROBEAST/MICROBEAST PLUS only recommended for helis smaller than 450 size?''<br />

''Why is using a single Spektrum remote satelite directly connected to MICROBEAST/MICROBEAST PLUS only recommended for helis smaller than 450 size?''<br />

We say it is not safe to use a single remote satelite on anything bigger than TRex 450 size as the chassis on larger helis may hide the satelite in different flight situations. So you will loose direct sight between TX and RX more easily on larger helis. Additionaly with larger helis typically you fly further away than with small helis, so this doubles the risk of loosing the RF link when the satelite antenna is hidden. Using an EU Version of the Spektrum TX it is very likely the rf link may get disturbed in such situations as these radios do not have so much rf power output. If using an US version of the Spektrum radio with 300mW output power this can be different though. But also here we can't give a general rule, as the quality of rf link depends on many other factors like such mentioned above (Where is the satelite placed? Is direct sight to the TX in any flight condition guranteed? How far do you fly away? Are there obstacles in your flying field like tress or houses? ...). So it's hard to give a definitive limit and we only recommend to use this setup on small helis as this can be considered as safe application.<br />

* The HeadingLock gain of the tail gyro is too high. Reduce the HeadingLock gain in [[Manuals:MB_Plus:Parameter_menu_D|Parameter menu point D]] by one step and increase the tail gain on your transmitter instead.

* Due to mechanical issues the tail gyro can not work precisely. Check the linkage and mechanics for absolute free movement without hard points and use a dedicated rudder servo that is fast and accurate and that allows a high control frequency.<br />

{{QUOTE|'''Please do not confuse:''' A slight tilt of the swash plate when the heli is standing on the ground is absolutely normal when the so-called integrators are not fully discharged. Especially when carrying the heli or steering the sticks this can happen as the system tries to perform the necessary commands. But as the helicopter will not move as intended the system tries to keep the servo movement until the helicopter may turn. Only after approx. 30 seconds without moving the helicopter or touching the sticks, the swash will return to its normal position as the systems slowly clears its memory. The exact amount of time for this depends on the position of the thrust stick. In the middle position is the discharge at the fastest. So if possible always keep the thrust stick in center position when the heli is on the ground so that the swash plate stays leveled. Once the helicopter is airborne you will not see any of these effects as now the control loop can operate as intended. As described [[Manuals:MB_Plus:Flying|here]] to center the swashplate you can also move the cyclic stick(s) to full deflection once as this will clear integrator instantly. Only if the swash moves downright by itself to full-stop even after correcting with the sticks and only cycling power off and on resolves this problem, check that your transmitter does not send any unwanted control commands (trimming active, stick pots worn out, ...). If this is not the case please contact support as maybe there is some problem with the sensors then.}}<br />

* The receiver power supply does not seem to be sufficient. The voltage during operation dropped in a critical area (<3.5 Volts). Use a stable power supply and make sure that the wiring and plugs are dimensioned big enough and feature low contact resistance. On large helicopters we recommend to use the MICROBEAST PLUS HD or AR7300BX unit with high power input.
