RE: Engine experts opinion required
Is this a "ducted fan" application?? Or a "push prop".........I think your complicating matters here! You cant compare a F-16 or even a real MIG 21 to a .49 MVVS RC engine and model! If your so concerned about power loss then move the .49 up to a .52.....the Magnum XLA .52 ABS "Blue Head" is an excellent application! Or buy a Rossi .45 at 2.1 HP.....it will still outperform MOST .75 engines! Even if there is SOME power loss (1 to 2%)... I serioudly dought it will be noticable!! How much could it be?? NOT MACH 1.....that's for sure!!
