Yes sir, I have the engine mounts here but mounting F1 is the last step for some reason, the 125 is anxious to get on there. I am going to power the CHI with a 7.4 volt battery and the receiver with a 6.6 volt LIFE battery. What does coreless mean? The servos are all JR E 355 except the throttle.

I have these Hangar 9 mounts in 120 size.

6.6V servo, good with Li-Fe battery set up [Control Signal Type] PWM Only [Stall Torque] 3.0 kgf-cm (6.6V) / 41.7 oz-in (6.6V) [Speed] 0.1 Sec/60° (6.6V) [Weight] 25 g / 0.88 oz [diemension] 35 x 15 x 30 mm / 1.38 x 0.59x 1.18 in [Length of lead harness] 250mm [Operating Voltage] 4.8V - 7.0V (Li-Fe 6.6v recommended

This tiny little guy will be the throttle servo.
