Joey, very cool!! I presume you are talking crankcase pressure, if that is right i would love to know your set up and starting procedure.  I have always had problems using crankcase pressure on these small engines. Looks good!,   Ray

Hi Joey,

When Pat first drew the 207 up for me, it had flaps identical to the 576 but for a .061. ;D  Did you alter it or has he changed the plans?

Hi Bill,
Pat added a note to the RM 207 plans saying: "Flap Options - The flaps maybe connected as shown, or glued on fixed".
I built mine fixed, no regrets, flies great!

Was this 207 built from plans or a kit ?
