well i flew the final setup at Mckoy today . thanks for talking me through the flights Jason , i managed 2 take off and landings , but having someone talk you through it for me was definately the way to go at this stage .
the 5055 700kv was a ripper of a motor , but had a little bearing noise , and needed spool up time , and was happy to suck 100amps 2100watt with a 13x6 prop . ( only rated at 1550watts)
so i threw in a more efficient 5050 580 kv 2000w motor with a 15x6 prop , which pulls about 1550 watts at 80 odd amps , so it could pull a 15x8 , but the 15x6 was very good for the plane and certainly not short of power ( think 100km hr vertical spiral) .
As the plane hadnt flown with this set up before , Jason had the 1st flight , it didnt need any trim and flew straight both level and inverted , so the balance was spot on , large loops werevery symmetrical , i remember calling it a pattern plane by mistake in the air .
anyhow the plane felt great and made flying look easy , it's weight with the bigger motor and 3000mah 6s battery is at 2.4 KG , I ONLY FLEW IT ON 50% RATES WITH 40% EXPO , and found that quite sensitive , i'll leave the 3d flying on 100% for a little further down the track if the good lord allows time with this beast . it wasnt that easy to land and certainly challanged my thumbs , so i wont fly this without supervision me thinks for a while , no trouble flying it at all , but it's longevity being the main point . i'll have to increase the practice now . OHH YEAH THE 580KV MOTOR and 15X6 prop gives it that lovely scale prop sound .
note : my little foamy has a checkered pattern on the underside of the wings , the MX2 has a checkered pattern on the top side of the wings . these things need to be carefully planned and thought out .
