HobbyZone Super Cub Aileron Modification

This blog post is under construction.

This is Part 2 of a three-part upgrade to my HobbyZone Super Cub.

Part 1 was a Spektrum radio conversion
Part 3 is a semi-scale LED lighting upgrade (link coming later)



Project Overview

The HobbyZone Super Cub is an excellent 3-channel training airplane, with decent stock power, docile handling, good slow-speed performance, and benign stall characteristics. It also has the benefit of being very durable and easily modifiable, with replacement parts readily available.

After mastering the stock 3-channel configuration, the next logical progression is to move up to a 4-channel plane. And why invest in a new plane when you can turn the Super Cub into an ideal 4-channel trainer? All you need is a radio/ESC upgrade (see my other blog post on this topic), a couple of servos, and no fear of slicing up your Cub's wing.

This project will lay out how I turned my Super Cub into a 4-channel bird. I welcome all questions and comments about my constraints, methods, and/or results!

Benefits/Downsides
  • + Much improved responsiveness in turns
  • + Allows Super Cub to be used as a low-cost/low-risk 4-channel trainer
  • - Slight added weight; offset by the use of a micro receiver such as the AR6100 instead of the big stock Rx/ESC brick

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

HobbyZone Super Cub Spektrum Radio Upgrade

NOTE - This upgrade only applies to the older, pre-Spektrum version of the Super Cub. The new planes come in RTF and BNF versions, both of which already have DSM-compatible hardware.

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)
