I've been playing with a light weight HLG (7.2oz) with Spectra pull-pull. Previous experience with Epsilon type construction has been good with little need to adjust the pull-pull as the strings stay tight enough with the glass covered, balsa slab surfaces. However my new HLG uses skin hinged foam surfaces (15psi foam with .75oz glass). This hinge is not strong enough to hold the required tension on the strings to maintain slop free surfaces. The hinge deforms from this (light) load and the strings go sloppy. Perhaps a doubler on the skin hinge would work, but pushrods would also work on this construction. Still searching for the optimum solution. John Kappus [EMAIL PROTECTED] wrote: > > Does Anybody have any experience building and or flying a Corndogger HLG?

Why are conventional push/pull controls better? >I have an Epsilon by Fred Mallet. I believe it is essentially the same set up on the Corndogger. The spectra system works fine. The control input is positive with no flexing and litte chance of flutter. >Keep in mind you must check it occasionally and retention as necessary. It takes about 2 minutes for both rudder and elevator. It is extremely simple, stay with the plan. >Darwin N. Barrie Scottsdale AZ RCSE-List facilities provided by Model Airplane News.
