Hello everyone,
Just wondering if the gap seals (ailerons, flaps, horizontal stab, vertical stab) as well as other modifications that Denver Jacobson did on the build of C-GXTR (M-18X) was worth the effort. It appears to me that this Continental A-65 powered Mite is at least as quick as book (and climbs like crazy), even with the 1025lb gross weight licensed by Transport Canada in the homebuilt/experimental category. The attached photo shows 116-117mph IAS @2150RPM cruise at 3650'ASL (5-10MPH tailwind component as displayed on GPS). On occasion with short bursts of full power (15 seconds max), I get an IAS of 135mph and once had seen VNE in level flight. I have also attached a photo of GPS max ground speed in level flight (with a real strong tailwind, full rich, full throttle short duration). The reason for the post is to determine average cruise numbers of the light weight Lycoming powered M-18's compared to the heavier stock Continental powered M-18's (and to the highly modified M-18X, C-GXTR).
Blue Skys!
