Hot Max and Super Max (oz8436)

About this Plan

Hot Max & Super Max. A1 class competition free flight glider. Note this is one plan showing two designs. Different wingspans, different fuselage boom lengths. Designed by Jorgen Korsgaard of Denmark.

Quote: "THE FIRST Super Max was designed, build and flown during 1979, following my club's basic ideas on a tough A-1 Glider model based on our novice model used for years. The model had constant chord wings, a simple fuselage and the Koster 66 airfoil which is superb for these small models - with and without turbulator. The new 'Super-Max' performed well and one of the juniors (16 year old Heinzi Lorenzen), actually won most of the contests with it. Indeed, he insisted we called him 'Sir' after these successes!

I then stretched Super-Max to produce 'Easy-Max' (I got tired of Wakefield flying) in an effort to give 'Sir Heinzi' some more serious competition. This was in 1981 and the new model did the trick.

I won 'Jyllandsslaget' the famous international free flight contest in Germany with a full house, the Danish nationals, etc, with the same model and a new, further developed version called 'Hot-Max', The latter employed tapered tailplane, lots of webbing and diagonal bracings.

I was, and still am, impressed with the performance of these small gliders - their ability to be catapulted off the line gaining height and very fast transition into the glide without severe stalling. We use no circle tow units, just a plain hook, the right amount of wash-out and a very small tendency to go to the right on tow. The only disadvantage is the lack of facility to thermal hunt with the model on the line - you can only tow straight ahead. Thermals must be detected from the ground or by 'piggy backing'.

The best version of the 'Hot-Max' was with square tailplane and slightly larger tips, built in 1981 and won me the title again! This model and the latest 'Super-Max' are shown on the plans. The latest 'Hot-Max' was lost at the nationals in 1982 (D/T'd but went OOS) where I placed third. Heinzi won with his new 'Super-Max'..."
