I put two of my plans on Dropbox for free download (for private use, not commercial). In times of Corona the best thing to do is stay at home and build another model.

The first plan is for the Gnumpf-X, a model designed in 2006 for pylon racing but due to perfect flying characteristics also suitable for fun flying or just running in of new ic engines (free motor mount means good cooling). Two airfoils are possible, I would recommend SD6060. Faster than the 8052 but as easy to fly.

In case you don't have thin plywood available for the fuselage, 3 to 5 mm balsa will do the job as well. You just have to change the frames to a bigger cutout.

In Germany there still is a small pylon class where the Gnumpf-X and similar models are flown at speeds from 180 to 250 km/h at low height for four minutes around a tight and short course. The models are powered by up to .32 ic or electric engines. The complete equipment is standard material and therefore very cheap. Only the unlimited class take these stock motors and beef them up a bit.

The plan is written in German, tell me if you have questions.

Best regards, have fun building and flying and stay healthy,

The other model is a 1/12 Hawker Tempest and yet untested, not build and flown. In 2009 I published a plan for the Hawker Typhoon which proved to be easy to build and fly, very tough in aircombat contests and is build until today in good numbers. I made the minor changes from Typhoon to Tempest already in 2009, but never managed to build one due to many other projects. If you recognise any mistakes, please tell me so I can correct the plan for other modellers. Also position of COG is drawn only approximately. Pictures and experiences from you would be helpful to bring this plan in a modellers magazine one day.

I've flown the Typhoon with .15 and .20 engines, others used .25 and also electric motors of around 300-400W and 3S3000-4000 accumulators. It's a small and light aeroplane and doesn't need much power to fly. For aircombat contests and the tight manouvers flown more reserve is needed, of course.

As a guidance for building the Tempest, it's a good advice to follow the build of the Typhoon:

More information about aircombat can be found here (it would be great to have more pilots from Britain in future contests

Best regards, Timo

PS: For inspiration I collected some links:
