Novarossi PLUS.21-4BTT TUNED 4 Port .21 Off Road Engine (Turbo)
Hi. My very good friend just won the Danish National with a BTT engine. His engine has been running +6 races with semis and 45 min a mains in all races. He has only changed the conrod mid summer. Not that it was worn out but for safety. Otherwise its bone stock :-) Novarossi engine are the best on the marked!
