The Trottel - a simple and versatile aerobatic/3D machine, free plan
The Trottel (German for fool) is a very simple, not very beautiful flying machine that takes a lot of abuse. Quick and easy to build with excellent flight behaviour.
It is a free downloadplan in German Modell-Aviator magazine 12/2016 Download is here: http://modell-aviator.de/files/av121...an_trottel.pdf |

Can't believe the lack of interest in this wonderful design. At one time everyone had a Stik. Phil Kraft's Das Ugly Stik from 51 years ago was a mainstay of the hobby, way before we discovered the advantages of electrons and 3D flying. Most all designs based on this platform are still called Ugly Stiks around here. Well, by us ol' dudes anyways.
A couple being built locally as we speak. http://outerzone.co.uk/plan_details.asp?ID=1253 |

If your using cheap 5 gram servos you can enhance their performance and life span by taking the top off and greasing the gears liberally. I use a #6 cut off round paint brush and Teflon based grease. Make sure you get lots on the output bearing surface, which is just a molded plastic shoulder.
Once done, work the servo on a tester for a few minutes. The first thing you'll notice is how nice and quiet they are. Good to do on those cheap 9 gram ones too. Actually, I do this to all my servos, even the expensive MG BB digi ones. Lots of grease at the top keeps the water out. ![]() |

Thomas,
This looks close to my Top Dawg Design for Foam. https://www.rcgroups.com/forums/show...wg-foamy-Racer As mine is set up for racing I never considered doing 3D with it. But , I DID try and now I believe that if I increase the surfaces size or possibly just the Deflections to 3D proportions that it might be more equivalent to your Trottle. Thanks for waking me up to another possibility. |
