Hello Englishal,
I think you can change planes, if you give plenty of notice.
The important thing to remember is the performance, time to fly the course, time overhead the start and calculated (by us based on your info) finish time (point seen at Jersey).
This is crucial for safe separation of the competitors.
If your figures/performance is the same, your new pride and joy would not be a problem, just a small ammendment in the administration records.
For further info please contact our Rally Manager on

Look forward to seeing you there.
