Mini-Max 103

Basic UltraLight Motorized welcome to the world of low-budget flying

This ultralight is a classic one. Been available since the 80's. There are a lot of versions of the Mini-Max. Two ultralights (103 and 1100) and the others have a few options (closed cockpit for instance) which make them just a bit too heavy to be ultralight.

I am sure. For each taste a version available.

The site of the manufacturer says the following about the Mini-Max 103:

"Easy to build -- Fun to fly!
A true light aircraft requiring minimum investment,
minimum building space, minimum time or skill...

Designed for ROTAX 277 or similar engines
3-axis control
wood construction
AN hardware
easily transportable with removable wings"

A construction picture of a Hi-Max, the high winged version of the Mini-max.

I got this construction picture of a person who mailed it to me. But ... I forgot his name.
If you know the owner of this Hi-Max wing, please, let him contact me again.
I want to give him the earned credit for this picture.

Here you can see another airplane by JDT.

It is one of those other versions of the Mini-max.
Pity, just a bit too heavy to be a ultralight.
I found this picture in the Ison-ultralight Yahoo group.
