Understood - but still 'interesting' for a biplane
I'm sure you won't want to use spoilers on that airframe, it's very draggy. A fair amount of power is required on the approach.
If you are using Futaba you can achieve this with a progarm mix in the TX. Nose steering channel is slaved to rudder and inhibited when the gear switch is thrown to gear up position.
I'm not sure the Mercury could do it, but Richard will confirm - seems complicated even if possible but simple in the TX
I have this set up in a 14SG and 18SZ if you want a photo of the setup. No sequencing but the Mercury uses a single channel/switch to control all outputs for gear and door actuators.
I think you have sold the iGyro/GPS combination short...
Once the gain is set it per instructions, it does 'automatically' adjust gain according to speed.
Perhaps the question was open to interpretation
Have you got Malcolm Holt's book on the 14SG?
Kindle book on Amazon. Essential for understanding the 14SG
Very timely bug fix for me - I'm just about to set up an iGyro SRS with Cockpit
Are the lights on a proportional channel? If so use that for gain. You only need gain for initial setup
I've done some more tests.
Set up: Google pixel 2 XL Android 10, Bluecomm iOS, Powerbox Royal. Royal updated to v20 using BlueCom and current iOS App (using someone else's phone...)
Power up Royal with Bluecom connected - set Royal to PC control
Successful pairing phone and Bluecom
Connect Bluecom to phone - successful, phone reports connected on BT set up screen
Start up Powerbox App
App reports cannot find Powerbox device - pressing OK terminates
Restart app - loads main screen and hangs permanently
Hope this helps - I have screen shots if it will help.
Ok thanks for the help, I'll get some more structured results later today.
It seems related to connecting to the Bluecomm, but exactly what state the BT connection is in is hard to work out.
Pixel 2xl on latest Android updates
I should say that it loads the main screen and then just hangs
But it specifically asks for location and phone and contacts. Not all apps do this. I understand the need for storage and BT.
However it's not starting properly even with all the odd permissions granted. I've removed and reinstalled. I just have the rotating ring.
This Android app seems to have some odd or rather excessive permissions... Why does it need access to location and the telephone?
In any case it hangs on start up on my Pixel2 even if I grant all requested permissions
The gain figures imply to me that the GPS speed sensor isn't being used.
In my view this is a must have. Without it you can't get the effective low speed gain you need for good stability. It's a great feature!
The manual says use RX1 and RX4 for Futaba - it works for me with 7003, 7006 and 7008
I have to ask - I've been resisting... Will the update include the iGyro performance update?
There are no SBus or other serial outputs on the Mercury. Mercury outputs are PWM.
The Royal and Champion have Powerbus serial outputs which you can use with PowerBus to Bus units to connect to Sbus servos.
My advice: why not try it it and decide for yourself. After all there's a switch to let you decide which mode to fly in.
The PowerBox iGyro gives a very natural feel in any mode - it's the best I've used and why they are in all my models. The GPS speed regulated gain is a fantastic feature, and I suspect, is much more reliable that an airspeed pitot sensor - the GPS wont get dirty.
There are two things to watch out for :
1. If you let the speed drop to zero in hold/attitude assist, funny things happen as the speed picks up, e.g. a stall turn. No big deal, it sorts itself out.
2. If you have hold/attitude assist on the rudder and attempt a turn (without rudder) the tail drags. This is why the manual says to have a mode with just rate on the rudder.
Its easy to get used to switching modes in flight, but it is one more thing to check at take off, so you don't have unexpected flying characteristics e.g. hold on rudder - it might surprise you when you turn after gaining flying speed.
