Yes well done Royal Mail, it arrived first thing this morning. By all means contact me. If I can help I will. Same goes for anyone else. If you want to send me non-working kit, I'll take a look. No promises, no guarantees, but no charge either. If I fix it and you are happy then make a donation to your favourite charity.
Forgot to mention that these servos are definitely not waterproof. Keith's showed some water deposits, so don't leave your boat sealed up between outings.
