So besides using a good stable and high rated power supply you have to ensure proper supply of the servos with this power. But when only connecting one servo plug with power leads into the receiver this may insufficient and cause a "bottle neck" in power flow. Also when the current must take a long way through the receiver, the wiring and the MICROBEAST, this will produce high resistance due to the connections in between and additional loss of voltage. There is no benefit if the power supply/BEC itself can deliver 20-25A when this amount of current is not able to flow to the consumers.<br />

Now the idea behind MICROBEAST PLUS HD is to provide a power connection that allows for using thick power cables and directly connect these to the unit, close to the servos. So the voltage loss due to wiring and plug connection is reduced to a minimum. In general for helis with standard size servo you should always use MICROBEAST PLUS HD, because this will eliminate the "servo plug problem" as one important factor that may be critical in regards to the power supply. But also keep an eye on the design of your power supply in general. I.e. when using an ESC with only one BEC line there will no benefit of using the HD version as you already have a "bottle neck" at the power output. The small wire will not be able to transfer more than 5 Amps continuous current. Connecting this little wire to MICROBEAST's HD input will not help very much here. If on the other hand you have at least two or even three BEC lines then this can be different as you may solder the power wires from the BEC together to the MICROBEAST PLUS HD high power plug.

Probably the gain of tail gyro is too low.
* Check assignment of gain channel and adjust the gain in the transmitter as described [[Manuals:MB_Plus:Flying|here]].

===MICROBEAST / MICROBEAST PLUS with single SPEKTRUM remote satellite on large helis=== <!--T:60-->
''Why is using a single SPEKTRUM remote satellite directly connected to MICROBEAST / MICROBEAST PLUS only recommended for helis equal or smaller than 450 size?''<br />
''Why is using a single SPEKTRUM remote satellite directly connected to MICROBEAST / MICROBEAST PLUS only recommended for helis equal or smaller than 450 size?''<br />
<br />
We say it is not safe to use a single remote satellite on anything bigger than TRex 450 size as the chassis on larger helis may hide the satellite in different flight situations. So you will loose direct sight between TX and RX more easily on larger helis. Additionally with large helis 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 even more 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 satellite placed? Is direct sight to the TX in any flight condition guaranteed? 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 helicopter's linkage ratio is not suitable for flybarless usage. In Setup menu point J adjust the cyclic pitch to exactly 6 degrees and make sure the color of the Status-LED lights up “blue”. If this is not the case change the mechanical linkage ratio of the helicopter (i.e. by moving the linkage balls further inwards on the servo horns, by mounting longer linkage balls on the swash plate outer ring or by mounting shorter linkage balls on the swash plate inner ring).

Apart from this also make sure the helicopter is well balanced (center of gravity setup correctly?) and servos are trimmed properly. <br />

The flashing Status-LED shows that a software-reset occurred during operation.
The flashing Status-LED shows that a software-reset occurred during operation. This can have different reasons:
* 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.
