There is an idea to develope a clipped wing version of the CX4. Anyway sporty looking, it seems to be a little step to make it an aerobatic aircraft. I dont know what the designer would say, but the CX4 is still an experimental aircraft - so maybe changes are allowed. Sure, it will be not longer named a ThatcherCX4...
The sketch shows a tappered wing. A wingspan of 6,6m (21,6ft) here. For maximum flexibility the wing should keep the existing connections.
