Hi everyone!I'm mochopiupiu and I'm presenting my Back engine racer!....now I'm concentrated in making airplanes with engines on his backs!this one goes for 500 miles like real world racers….it can take off and land on water as it don't have weeks.u can fly up to 1 hour and if u want to fly more time you can add more fuel to the fuselage...but that will reduce the speed of the airplane….just one note...some of mine rear engine airplane have frontal pich controls….to get better performers in piching u don't need to pull or push the controls a lot….just a little push is enouph…oh and this airplane runs very well at any configuration….hope all of u enjoy my airplanes...see you in the sky!
