These are my notes on the Cessna 182 RTF from Hobby King.

I had to replace the XT60 connectors on the charger and battery with Deans connectors to suit the plane. According to the guy at Hobby Habit XT60 is mainly a US thing. I also replaced the alligator clips on the charger input with a molex connector so I can power it from my PC.

The manual is not much use as it's missing several vital details (for a novice anyway).

• The ESC powers the receiver directly, not with a separate cable, so it plugs only into channel 3. The battery port on the receiver is used with the bind plug to rebind to the transmitter.
• The receiver & servo pinouts are undocumented, see the following table & attached image.
• There was not much glue and it smelt like PVA so I used some of that.
• The receiver is quite programmable using the USB cable ($3 from HK) using this software ($2).
• By default switch A selects between single (toward you) & double (away) rate and switch B kills the throttle (towards you = no throttle).
• The transmitter channel assignment is shown in the picture, all of the sticks have centre springs except for channel 3.
• ESC "manual" (Skyartec BMC-25A)
• I got a Turnigy ESC programming card on the assumption the plane had a Turnigy ESC but it has Skyartec, card seems to work OK though.
• The motor is a Skyartec WZ12 Outrunner 1530KV which has a shaft size of 3mm.
• The propeller is 8x6 and needs a small hub (10mm) for the spinner to fit on
• The curvy side of the prop should face forward (typically this means the writing should face forward).
• The first time you use the ESC you have to set the throttle range, check the ESC manual (search for "throttle range setting")

Technical

• The receiver has what I think is an Amiccom A7105
• There is also a 24C02B which should be a 256byte I2C EEPROM, although I can't determine the maker (probably .cn cloner).
• There is a mystery chip which drives the PWM outputs, not sure what it is yet, hopefully a CD4017 so I can MitM the PPM.
• Servo & PPM output signals are at 3.3V.
• The signal pin on the battery connector looks like a PPM output.

Simulation

• Install PPJoy (special pre-release version)
  • Windows Vista and later need to be run in test signing mode for the PPJoy driver.
  • I needed to reboot before the PPjoy joystick showed up
  • Note it doesn't show up in Devices & Printers but you can run control /name Microsoft.GameControllers
• Get T6sim
• ClearView ($40) and FMS (free) seem to be the only sims which work with a Windows joystick.
