I just finished porting my pro 15 and expecting big things. Was much harder than i expected as i only had limited attachments for my dremel but got the job done. Ive tested it to make sure it actually still runs and it does! Gonna run it in 2morro and after that it will hopefully fly!! Wot results has every1 else had outa there ported pros?
Mine has much better TOP END !.Did you put the stock bearings in?.I replaced mine with boca high speed ones for 26.00 .The motor will hold up better than the stock ones.Run time is still good too.I get 10 min to a tank of fuel.
