The Spirit Pro is an excellent unit. I’ve set up dozens of them so If any questions feel free to ask. The SPM4651t is a good receiver option.

The FC6250HX comes with a telemetry Rx (SPM4651T) so you don’t need to buy anything extra. I’ve never used this FBL but as far as I know it can only be setup from a Spektrum Tx, your DX9 would be ok. if you want a PC setup interface I suggest the Brain2/iKon2 or the Spirit2. You would then...

USB2SYS is a BeastX product, so not compatible with the Spektrum FC6250HX. The good news is you dont need to connect it to a PC. All of the setup is done from your Spektrum transmitter. You only need a USB adapter for updating the firmware. For updating you would need the Spektrum USB adapter, I...

Hard to know if there is a problem without more details, preferably a video. However servos on a FBL do not move directly in accordance with stick input, which is perfectly normal for a FBL heli but can cause confusion. If the servos operate normally on a servo tester then you can be pretty...

Have you setup the ikon according to the manual? With a FBL you cant just plug in the servos and receiver and expect it to work correctly. The FBL neeeds to be setup to suit the specific installation, equipment and heli mechanical layout etc. Also the transmitter needs to be set to swash type...

This indicates that the internal resistance in the battery is very high. What hapes is when you put a discharge current on the battery, due to the high resistance the voltage drops very quickly (V=I*r). The voltage hits the storage charge value (3.8V) and discharge stops. Now that there is no...

Nothing special really. Just give the heli a good check over and lubricate the swash where it slides on the shaft and also the tail slider, you should be good. For the batteries check for any puffing and check none of the cells have lost voltage while stored (indicating a faulty cell). When you...

Nice servos!

Also make sure you don't have swash mixing set in the transmitter. For most flyberaless controllers swash type needs to be set to 'Normal' or 'single servo'. Swash mixing is done in the flybarless controller itself. Having 120 deg (for example) swash type selected will cause the channels to mix...

There can sometimes be burrs around the edges of the bolt hole in the shaft that stop the swash sliding over. A quick 'tickle' with a file to remove any burrs usually does the trick.

Heat is not a big issue but what you need to do is put the motor in a zip-lock plastic bag, poke the shaft through the bag and seal with tape. This prevents metal filings from getting into the motor.

Both PL6 and PL8 have maximum charge current of 40 Amps so the extra power of the PL8 can only be realised if charging 7 or 8s packs. The extra power of the PL8 is useless on 6s packs because a 6s pack at 40A only needs 1000W (25v x 40A = 1000W) in any case the only way you can use 40A charge...

The 6s version is good for 90% of applications. The only time I’ve needed more than 6s is when I’m charging my two 7s packs from my 14s setup on my TDR2 A few setups use 7s or 8s packs but not very many

I’m an iCharger man myself but you can’t go wrong either way. ISDT chargers look good too at a nice price point

Unless you have a VControl Tx then flight modes can only be set in the transmitter. I'm not aware of a receiver than can do flight modes but there are several flybarless controllers that do 'banks' which is somewhat similar.

Good that you figured it out. The 'capacity limit' does not have to match the battery. As I mentioned in my last reply, i'd recommend disabling this feature altogether or if that's not possible just type in the largest number you can. A quality charger is definitely a great investment. It will...

here's the official SAB video: And the specs: It is very much modelled on the 700 Kraken although the transmission layout is like the traditional Goblin design with the tail belt driven on the bottom of the main drive pulley rather than from a seperate output shaft at the rear like the...

What capacity limit have you set in the charger? It could be that the limit is too low so it's hitting it before the battery is charged. I'd either disable capacity limit or if it cant be disabled then set it the largest value that you can type in (e.g. 999999 or whatever). Don't worry, the...

Did you realise that the thread was nearly 3 years old?

Gain means the same thing on a plane or a heli. It relates to the 'sensitivity' of the gyro control. Technically it's the ratio of output signal over input signal. Or more specific to a plane it's how much control surface correction you get from a certain movement of the plane from it's starting...
