Didn't check the pitch, but did not notice any funny vibration. I forgot to mention I could get it trimmed out perfect before take off. No change in the feel of the pull on the ground. Get it in the air fine to start out, but would wane after 5 or 6 laps, or sometimes die just after takeoff.
My buddy with the Golden Bee keeps telling me I go a POS engine and I'm like, man I never have any problems cept when your around. Aggravating cause I build nicer planes (He goes for nothing but sheet wings (no prob there) but refuses to prep sand, fill in, or even knock the "hairs" off the balsa. They fly, and look okay in the air, but man are they ugly up close. Usually heavy too. Require a real running start to get in the air.
Plus, I can fly circles around him. He's happy with just up and down and maybe a loop or too. He always asks me to fly his planes to see what they can do. Upside down, fig 8's, wingovers, doesn't even care when I crash his planes (which is kinda cool). He's just not comfortable trying it.
So what can I do? Note: I'm running 35% Norvel fuel. 6X2 APC prop. Pressure coming off the muffler to a clunk tank. Have the EXACT same problems with my .061 Wasp and .049 Big Mig Norvel.
