'Like to go Large, sir?' - the WOTS WOT XL biplane from the Chris Foss stable is a big aircraft with a big engine

Logo for Ripmax Ltd At nearly 1.7M span (66.5 inches) and with a 25-35cc petrol engine up front, this is a large and impressive ARTF model

Ripmax XChris Foss Wots-Wot XL BiplaneWhen a model is as good as the Wots-Wot there is only one way to make it better - make it larger, which is what's been done with the new Wots-Wot XL. The increase in size has resulted in even better handling, with amazing low speed stability alongside stunning aerobatic capability and precision.

Designed around the popular 25 - 35cc petrol engines but also suitable for larger glow engines the Wots-Wot XL has a fully built-up structure from precision CNC cut balsa and ply, the assembled model then being carefully covered in film, whilst the fibreglass cowling is painted to match.

To enable easy transport and storage the Wots-Wot XL is easy to assemble and disassemble, the moulded wing struts having a single attachment screw at each end, whilst both wing panels separate into two halves. Once disassembled, the Wots-Wot XL will fit into standard estate cars and many hatchbacks with room to spare.

The original Wots-Wot was a conservative 48" span and designed for 10cc glow engines, though a 90 4-stroke was a suitable alternative. The new 'XL' is nearly 40% larger in span with a considerable
increase in wing area to match and it will surely be very popular - Chris Foss's models have been around for 50 odd years and I don't think he's ever designed a bad aircraft.
