HobbyZone Super Cub Mods Part 2 - Aileron Mod
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)
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!
These items constrained how I approached this project. If you don't share the same personal preferences you can adjust the project steps accordingly.
Tools & Materials
Step1 - Flatten the wing
The wing of the Super Cub is designed with an amount of dihedral appropriate for a training aircraft. Unfortunately, the roll stability generated by the dihedral tends to counter the effect of ailerons. You can still get a Super Cub with full stock dihedral to roll, but it won't be nearly as responsive.
Most people use one of two methods to flatten the Super Cub wing: insert a carbon fiber tube/rod, or use packing tape on the bottom to absorb the tension of the wing wanting to "spring back into shape". Several people have used a hair dryer to soften the foam prior to either method.
The method I used (packing tape, no hair dryer) is simple and does not permanently alter the wing, however it's difficult to get a completely flat wing this way. In the future I will probably re-flatten the wing using the hair dryer/carbon-fiber method. For now, the packing tape works fine.

Boidster, This is by far the best blog on modifying the HBZ SC. I have been looking for one like this. The way you layout the blog. project overview, benefits etc.
I cant wait for the continuation of the blog ... will there be any updates soon? I am planning upgrading my SC too.
