You can get a ZDZ 80 single cylinder from France for £315.The cheapest ypou can get by miles. I think postage to a UK address is £15.
I did a lot of research on this because i was very close to getting a 33% Edge 540T from Alan Hawes.
You can find the french website under dealers on www.zdz.cz
I think you can get KS silencers for it from Als Hobbies or another shop.


I have never owned anything bigger than a 180 size motor, but the 82db limit shouldnt be much of a problem because the motor pitch is much less annoying. Because of this, most clubs dont bother asking to noise test you, because in the air its very quiet.You probably wont go over half throttle in flight with a ZDZ 80 anyway(50lbs static on a 20ish pound model) so it should rarely get past 82 anyway with proper throttle management.
