RE: Venus II
Three more flights today. The county park is still opening a normally 'closed field for the season' due to great weather. Tomorrow looks good as well.
Some of my observations.
I had to lean the low speed neede 1/8 of a turn so the engine would spool up quicker and hold idle more consistently.
Only using half throttle for most of my level flight. The 1.20AX seems suprisingly good on fuel, and I'm using Byron 10% nitro with synthetic oil.
The plane is suprisingly quiet for a 2 stroke. Got several comments including three 'noise committee members' that the plane was really quiet for a 2 stroke. I recommend using foam under the engine and against the firewall behind the mount along with an APC prop and the muffler diverter to help quiet the plane. Everyone I asked about the foam said it'd do nothing, but I feel it is helping considerably. It seems to work for me. Almost sounded like an electric up there - it was amazing! Of course throttle management and a well broken in engine seem to be helping as well.
I have one of those [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXL379&P=ML]Hobbico muffler defletors[/link] on the outlet of the exhaust on the bottom of the plane, which also does an excellent job of keeping the bottom of the plane from getting excessively oily.
Even though I ironed out all of the wrinkles from the monokote, they're creeping back slowly after only a few days.
A 17x6 prop seems just right, for me anyway. Slows the plane down at half throttle. Not a lot of clearance though between the prop arc and ground though, maybe 1.5 inches or less. I painted the tips of the blades yellow as I want to make sure I don't get my hands anywhere near the blade after starting, since the grey APC is a little hard to see. I carry a APC 16x8 and APC 15x8 in the flight box as well.
I think I'm going to add a little throw to the ailerons on low rates so my rolls are a little faster. 1/2" seems a little light.
I carry a steel ruler to direct the wing bolts into their holes when mounting the wings. A little bit of a pain. I have pencil point wing bolts and a triangle block glued above and behind the holes to guide the bolts as well but they still need a little coaxing.
The stock gear seems to bend easily. I had one hard landing and that is what gives this impression, seemed fine on all my other landings.
The stock wheels seem a little small and stiff and I think I'll switch to slightly larger, rubber wheels, and maybe a larger tail wheel. The plane taxies very well with the stock tail wheel though and really doesn't need an upgrade but the stock one sees small and flimsy.
I am nowhere near ready to even attempt the sportsman's sequence, although very easy for most of you I'm sure, with any real accuracy. But I plan on working on one or two maneuvers at a time.
