Hello Toxik
You Will Find That Breaking In 40 Is A Lot Easer Then A Car Engine And You Don't Realy Need After Run Oil.Just Make Shure Youu Use Airplane Fuel.i Like 18% oil And 15% Nitro.Car Fuel Does Not Have The Oil And To Much Nitro.It Will Run To Hot And Fry.That Is Why There Are No Old Car Engines.
I Agree With Flyinrog The Zero Is Not A Trainer.i Sugest You Learn With A Trainer And Save The Zero For You Second Plane.Trainers Are Not Realy Ment to Surive The Lessions.Mine Looked Like It Came Out Of A War Movie Till I Was Done With It.An Extra 1/2 Pound Of Extra Epoxy And 2 Foot Of Repair Tape were Added
Enjoy The Hobby We Will Be Here To Help.
