For a ignition it's all about volts, 5-6 is good.

Most CDI units draw less than 1 ampere. But there are a few odd ball ones that consume more though. So if the voltage regulator can handle 5 amps, that is perfectly fine. It doesn't hurt to have some extra current handling capability for those hot summer days where the airplane is exposed to the sunlight for extended periods of time at the flying field. Albeit in Canada it wouldn't be as hot in the summer as it is down here in Texas.

At peak in the summer in Quebec, 90f is a real scorcher for us. Summer is around 75-90.

I found this while browsing Hobbyking and may just go for it. I'm new to larger models so I need a little bit of guidance for 2 models concerning power to the servos.

Direct question: is this item enough for the Amr trainer 50 (g62) and the my 5 meter sailplane?

I will be powering the trainer 50 and the sailplane with 2 x 2s 2000mah batteries. To save weight on the Fashionista, I will be using a smaller 6s battery for the motor.

Trainer 50: 7 servos: 2 aileron,2flaps,1 rudder, 1 elevator, 1 motor
Fashionista: 6 sevos, 2 airbrakes: 2 aileron, 2flaps, 1 rudder, 1 elevator, 2 electric airbrakes.

here is the hobbyking link:

Turnigy introduce the Min Power Distributor Ubec suited to 30cc plus gas powered models.

This unit has great features, which include: Dual battery input, 5v isolated linear RX BEC, 30 Amp voltage adjustable Ubec on all output channels, 8 channel RX input with dual outputs on each channel - simplifying dual servo control surfaces.

Great inclusions are the independent 5V linear regulator providing a separate power source for the receiver, optically isolated CDI power & in built remote ignition kill. Receiver, Servo & CDI power sources are completely isolated from each other.

This is the first Power Distributor system to securely nest the receiver within the power distribution 'block' thereby shortening cable runs, adding protection to your all important receiver & speeding set up time.

Features:
• 5v Linear RX BEC
• 30 Amp Servo UBEC
• Users adjustable UBEC voltage
• 8 (+1 CDI cut) input channels
• 16 output channels
• 5 Status check LEDs
• Padded receiver tray & Secure mounting
• CDI isolated power
• CDI remote ignition control (remote cut)
• CDI power status indicator light
• CDI power output terminal
• CDI voltage monitor LED

Optional: Input/output voltage display with external power switch

Spec:
Input Channels: 8 (+1 CDI Cut)
Output Channels: 16
Input voltage: 7-13V
Servo UBEC Current: 30A (40Amp Burst)
Output voltage: 4.8-9.7V (user adjustable; Default is 5.2V)
RX power: 5v linear bec
Working temperature: -20 to 85 degrees c
Weight: 80g
Dimensions: 116mm x 88mm x 13mm
