HobbyZone Super Cub Spektrum Radio Upgrade

This is Part 1 of a three-part upgrade to my HobbyZone Super Cub.

Part 2 is an aileron upgrade
Part 3 is a semi-scale lighting upgrade (link coming later)



Project Overview
The radio system included with the HobbyZone SuperCub RTF kit is, to put it charitably, of fairly modest quality. I personally like the X-Port technology as an idea (a standardized add-on module interface), but unfortunately it is only available with a (again, being charitable) modest quality receiver/ESC combo and non-standard 5-wire servos.

I found the servos somewhat jittery, and the throttle on the transmitter very crude and unsuited to smooth landing approaches due to the lack of fine control.

This project will upgrade the Super Cub to the all-digital Spektrum technology, meaning a new receiver, ESC, and servos. Unfortunately, the X-Port will be lost - at least until a project down the road where I try to resurrect it.

Benefits/Downsides
  • + All-digital radio equipment = fewer glitches
  • + Greatly improved throttle control
  • + Standardized equipment for easy repairs/replacement
  • + Net loss of about 1.1 oz, using parts listed
  • - Loss of X-port feature
  • - Loss of Anti-Crash Technology (ACT) (probably a '+' for 99% of people)

Constraints
These items constrained how I approached this project. If you don't share the same personal preferences you can adjust the project steps accordingly.
