Benedini sound systems featured here on rcu google that name and you wont believe it. Dont get me wrong I have a stearman, tiger moth 1/5 p-47 and a 1/7 p-47 all saito and zenoah and they run great. However for twins i go for electric. I am finding that with that sound systen i may go all e power. Money is no object planes come first
