Hi Guys....Here's what the motors sound like on a circuit round my farm...

Got in several flights today for 1hr50min total....Thought I had the engine hesitation problem solved but apparently not....I'm thinking I might have to install two small tanks fed by the fuel pumps, with returns to the main tank...the carbs would then be gravity fed.....or maybe just put on the Tillotson carbs off the rotax's?....Simpler and eliminate the mikuni pumps altogether....perhaps
Funny thing, the motors run strong and steady, and then every now and then one or the other will give a slight hesitation, and drop a couple of hundred rpm, and immediatly pick it back up....Anyway I'll keep playing with them, and if I can't find the cause I'll have to try something different ..It's way too hard on my heart the way it is.
The plane flys a lot better now with the seat back, but I'm sure dissapointed in the climb rate....those ptip props are looking better all the time.
Cheers .........Pete
