There is a small steerable tailwheel and wing-mounted outrigger wheels.[3]

The flight won a £1,000 prize offered by the London Evening News for the best performance in the race by an aircraft under Script error: No such module "convert". gross take-off weight.[3] The main landing gear fork is an ongoing maintenance issue, with regular replacements needed.[4]
