First time posting here, but been a regular follower for several years, and flying for many more....
Having tried the majority of "reputable" engine shops around the UK on numerous occassions for everything from advise to engine overhauls, with varing degrees of satisfaction, or rather dissatisfaction.....
I was refered to a newish engine shop, AEP, by a regular contributor of this forum soon after he had his engine repaired by them.
An engine overhaul, several components and most recently a new kit engine from them, I can offer nothing but praise. Their advise, attention to detail and after sales service has been fantastic, definitely worth giving them a call.
