This is a description of how to setup a wireless buddy box connection to various trainee transmitters using a FrSky transmitter (ACCST D16).
The wireless buddy box is connected to the trainees transmitter using a standard mono jack plug (or other supported connectors), and the trainee uses the trainers transmitter as the slave, this has the advatage that all trimming is being done on the trainees own transmitter.
Bear in mind that the buddy lead concept is to connect the aileron, elevator, throttle, rudder signals from the Slave Tx to the Master when the Master slave switch is operated. These four control channels are combined into a single channel using CPPM (continuous pulse position modulation) in a buddy lead.
FrSky R-XSR and standard X4R can output CPPM signals, I used an R-XSR due ot it's small size and ease of switching to CPPM mode.

All wired up to the mono lead. I used a balance lead for power and removed the centre wire.

Once the CPPM output is wired to the signal line of the jack plug and the GND is connected to GND on the receiver you get the flexibility of setting up wireless connections for various transmitters.
The buddy cable sends signals from the Slave Tx to the Master Tx when the Trainer
switch on the Master is operated. To use a transmitter Slave Tx, create a simple four channel model and bind it to the receiver in the buddy box.
On the Master set the input to Master/Jack

OK, here we go. These are going to be the descriptions of the manoeuvres for the competition. They may not be exactly the same as the BMFA or MACI or any other organization but that does not matter. This is just a competition for our club and meant to just be a bit of fun.
All manoeuvres should be flown as if it was a full size aircraft with a full size pilot in it. In other words, you will lose points if you do a loop that would generate 15 G’s !
Any aircraft can be flown, including but not limited to helicopters and hand launched planes.
Manoeuvres will start out with ten points and will have ½ point marked off for each error.
All manoeuvres will be valued the same so it is up to you if you want to show off or just do the easy ones.
The first four on the list are set and everyone must do them in the order shown.
The next 5 are your choice. Number them 5-9 in the order you want to fly them.
You must call out the name of the manoeuvre before starting it. You can have a caller to tell you which is next so you don’t have to remember. Make sure you print 2 score sheets so your caller can read from one and I can have the other to judge.
You must shout “Now” just before beginning the manoeuvre and “Complete” when you finish it. See diagrams.
To keep it simple, we will stick to the manoeuvres on the list.
No punching biting or kicking in the nuts!
And that’s it for the rules.
Can be done upwind or downwind at your choice.
A centre line will be decided on the day and manoeuvres will be judged on being symmetrical to it where appropriate.
The last two (11, 12) on the sheet show how well you made the plane look real and how nice you flew it between manoeuvres. So don’t do 10g loops to get back upwind for the next manoeuvre.
Dat’s it boys. Either you are all going to hate me for this or we will have a lot of fun. Either way, I will be accepting the brown envelopes any time between now and.... anytime really.
PilocRC Extra 330sc build
Today we maidend two new models, Barry Waugh's PilotRC Laser 73" and John Allen's Aeroplus Edge 76".
Barry's Laser was powered by a PTE36R with FrSky RX8R & xm+, with JX 30kg brushless servos.
John's Edge was powered by a DLE35RA with FrSky RB10 with X8R and xm+, with KST BLS815 on the Elevators and Kingmax CLS2008S on all other surfaces.
Both maidens went well with little trimming required. John's Edge looks like it needs some downthrust as it climbed signficantly under full power. Barry's Laser looks to be a little nose heavy.
The latest Taranis transmitters & X series receivers have the EU compliant firmware, this means those old X series receivers need a firmware update to work with the new transmitter, and old transmitters require a firmware update to work with the new receivers.
I have an old transmitter, and when I got some new EU compliant X8R receivers I simply loaded the non-EU firmware to them and all works just fine.
FrSky's new transmitter, the Taranis X9D, continues to generate great interest. I've acquired one from t9hobbysport, and all I can say is its fantastic. Programming it is a bit different than Futaba/JR/Spektrum, thought Multiplex users would find it very similar. I'll have it up at the field at the next available opportunity, and will gladly help anyone who buys one to program it.
The 8 channel telemetry receivers X8R cost about €30 (ex delivery), and compare very favourably to the considerably more expensive big brand counterparts.
Non-telemetry receivers such as the new FrSky V8FR-II 8 are even cheaper, and are Taranis compatible in 8 channel mode.
This is an excellent replacement for the stock NiMh, although the more recent radios come with a 2000mah LSD battery which lasts all day.

At the Shankill Radio Flying Club we use Ghost to manage our blog. Here are some nice Ghost blogging guides. You can ignore the parts about installing and managing users etc... just concentrate on getting some stuff written.
By default Ghost saves your posts as drafts, you need to change the dropdown from "SAVE DRAFT" to "PUBLISH NOW" to actually publish your article. This allows you to work away on your article until you're ready to publish it, but still have it saved on the server.
