March and April are the two hardest months to find a weekend when the wind is not blowing or what I call gusty.
This afternoon after work it was as good as it gets this time of year. I am not sure why but the wind direction always blows in a direction where you are looking into the sun when stunting.
Anyway I change out my LA 46 on my Tutor II with my new ebay LA 46 with a Randy Smith NVA. I think this engine is going to be a keeper. I did want to try a 12.25x3.75 APC prop also.
First flight was kind of soft on the lines running @ around 9100.
Second flight was launched at 9700. Half way into the flight I started to hear a rattling nose and then the engine started to sag and then quit. I called my Tech support guy and he explained what happened.
I went back to my old prop, 11x4 APC and got in two patterens. I was a little rusty but it felt good to burn some fuel.
Things I learned:
* Don't load up a brand new engine with too much prop. And look at what size plane you are asking the engine to haul. Size does matter.
Something I'm not to sure about.
* I am using a lot less fuel. And I mean a lot less. I was using about 4.5 oz with my other LA 46, this one is using about 3 oz. Both have FP 40 venturi's. The only difference is one had a stock OS front NVA the new engine has the Randy Smith NVA. I like it.
