RE: New Patriot XL
Kmtranmd,
Thank you for your comments. Actually, the engine is a Magnum 91 XLS - just a clone of the OS engine. I was thinking to upgrade the muffler but I will fly it first and then to the upgrade. Is a 11X9 not too small for this engine?
I also mounted the battery pack in the tail but I still have to add some weight to balance it at the C.G given in the instruction. I was also planning to mount the fuel tank at the C.G but I may just fly it like this first. Are you using the flap deflection given in the instruction? Same amount for take off and landing?
Thanks,
Le fou
