RE: DL-50 engine
Yes it has the same markings. You know I have a friend who only runs DA and he is the one who I learned how to fly from. Now he does what you are say and just runs them but very easy for the first three gals. And does do the diffrent oils the no syn for break in and syn there after. You I i was in to racing off road nitro buggies hard core and we would take a OS VZB21 and just run it easy then let it rest for ten min or so and do that foe about three tanks. And then lean her out and start ripping up the track and may I say these are 400 dollar motor and we did it in the summer here in calif 110 weather.
