The flight computer i purchased is the Pooleys CRP-5 (Pooleys - CRP-5 Computer)
Is this a poor quality one?
The CRP 5 is a very good quality computer: My only thought is that for PPL study is a bit 'over the top'
Fine if you're going on to do commercial but it deals with higher speeds etc than you'll meet for PPL.
If you're only doing PPL take comfort in the fact that as soon as you pass the test, you'll never use it again and can flog it and put the money towards a small dedicated electronic flight calculator.
Job done.
