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.

Neue Kunstflugfigur: Der Rohlmann! (1 min 31 sec)

Span: 600mm
Airfoil: KFm 4
material: 6mm Depron
weight: ca 200g
motor. 20g outrunner
battery 2 - 3 s 450mAh
servos: 6-9g

It flies similar to the Eflite 280 Edge and Inverza, but is easier to control.
Ideal for recycling 280 equipment from damaged models.

Painting the airplane while it is in a hover. I do enjoy the way that you do things, Thomas.

I wish that I had thought of that.

A paint brush on a long handle would be safer.

Yes, with a ghostbuster - style compressor backpack!

Trottel is capable of VTO:

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.

Dear Thomas B.
Can you give more detail to build this plan?

A few mods ...................

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 molder 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.

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.

You can 3D just about anything with enough thrust and big control surfaces. Big surfaces because they rely on them moving air generated by the prop when flying slow or hanging around. Lots of rudder authority is a must.

Off to maiden..................
