Glad you are flying again.

:D Thanks guys I phoned CAA today and it seems like I will have to apply for a registration of a modification, get Mass and balance data and Application for the issue of a proving flight authorisation for micro light. Copy of log book and prove of purges from the supplier of the motor and then the fun and games can start.

Hi Bennie,

Ja ground runs do tend to lead to "lift" offs at 40mph


Kind regards
