Mini Super (oz14119)

About this Plan

Keil Kraft Mini Super. Radio control sport trainer model.

Note the first Mini Super design was drawn and built by David Boddington in the early 1960s, as a reduced 75% sized version of the EJ Webster Super 60 design - see Mini-Super (oz7900) for a later article which explains this history.

This here is the Mini Super as kitted by Keil Kraft. The plan bears the signature EJ Webster, and differs in several respects from the Boddo drawing, not least the tricycle landing gear and the pre-shaped balsa LE section used in the wings.

Quote: "Hi Mary/Steve, Earlier I mentioned in a comment about the KK Mini Super that I had found my original plans. Find attached scans made into pdf files of Sheet 1 and 2. These are the original kit plans and in common with all Keil Kraft kits some items are not provided. However the fuselage is a simple box so the formers can easily be drawn-up for those with some experience of reading plans. Sheet 2 shows the rib outline but not the dihedral braces - again this can be deduced quite easily.
I also provide two pictures of the original model [main pic, 003] constructed from the kit way back about 40 years ago (although these photos are after it was refurbished as part of UK covid lockdown 2020). Thank you for the wonderful resource that outerzone is. Here is a small contribution to your cause of having a repository of vintage plans. Best Regards,"

Quote: "Testing Keil Kraft's Mini-Super: Opening the £4 10s (including purchase tax) kit for this long awaited Radio Control design gives an immediate impression of completeness. Undercarriage is pre-formed, sponge rubber wheels of acceptable weight and a metal 'clunk' tank are items of hardware that the lone modeller really appreciates. As for the wood, this too is well prepared with a pre-shaped leading edge for the wing panels, and all parts cut ready to push out and assemble.

Being a KK traditional kit, utilising longerons and covering rather than sheet structure, the Mini-Super also brings with it a fair bundle of square strips. These need to be sifted to obtain four equal strength lengths for the longerons. Plans and instructions are good. Little is left to the imagination.

Assembly was a charm. Only the tail seat and fuselage parts P1 at the base needed slight trimming to fit. The nose cowl also needs a groove to accept a silencer but that really depends upon the engine and chosen silencer. Our selection was an OS Pet 1.6 cc glow plug engine with a Spinaflo unit. This proved adequate for the job.

Criticism of the structure is twofold. The tail is made of square stock, having superimposed strips added at positions which are then sanded to a section. We did not find this particularly easy and would have preferred to pre-cut the tail ribs with holes for the central spar.

Secondly, the front wing dowel is attached to the leading edge fairing and vertical struts only. It seemed insecure and proved vulnerable at the first test glide when the beautiful transparent windscreen shattered as the dowel came adrift. We now have a block screen alas!

Equipment used was at first a Kraft KV3K receiver and the new OS motorized single channel servos types S101 and S101M. The Rx was over sensitive to the servo motors and didn't function properly. It was changed to a 'Minimac' and the equipment works well except that motor control is sporadic. OS have to sort this out somehow - it was enough for us to fathom the tentacle directions of the 8 wire S101 Octopus without instructions.

At 2 lb 13 oz all-up weight the Mini-Super becomes quite a lively performer despite the 'trad' appearance in this age of cabinless wonders.

Verdict: top class value, just the right size to have for precision flying and adaptable to six channel multi-control. A perfect first R/C model."
