The Booster is an excellent power unit to work on with most tasks being easily achieved without the over head of fabric parts getting in the way. Maintenance seems to be a relatively new concept to most Hang Glider pilots as nothing much seems to go wrong with a wing (providing it hasn't been crashed). However, this isn't a wise approach for a pilot's well being, and it always amazes me that we don't actually have more accidents due to glider neglect within the sport of Hang Gliding in general. Gliders should be checked thoroughly and wires (especially wing wires) changed at intervals recommended by the wing manufacturer.
All power units do definitely require maintenance to get the best from them. Set aside some time between flying days to give the unit a good visual inspection of all fasteners, structural items such as strut attachment point, condition of the propeller, transmission etc.
These notes are from my personal experience with the Booster and should be considered in addition to the information provided by the Booster manual.

All Hang Glider power units that I know about use the Radne Racket 120cc 2 stroke engine. These are simple, light weight, relatively powerful and reliable little motors. The following notes are derived from my observations of using the engine within Booster units. Please consider them in addition to the information provided by Radne.
