Pedro, Tim,

Thanks for the complements. It's always nice to at least think I'm not totally crazy all the time.

Tim, Nice pics.

Pedro,

At this point, I'm right there with you. I also got mine as a possible entry into that type of flight. It seems like a couple of years ago, I was reading a part in a series of articles in one of the RC magazines on trim.

At this point in my flying, I'm starting to be able to perform many of the trickier maneuvers, but am not precise on any thing. I think I need to start flying larger, and more well behaved birds than the ones I'm flying now. Also, I need a lot more stick time to get the precision I need. Maybe when I retire in another 18 years. I tell you this so you can gauge what I say properly.

I'm having philosophical disagreements with what I read in the magazine articles. Mainly to do with how we all mount the engine pointed to the right. IMO, and I'm probably in the minority on this, it's great for horizontal flight. In that case the right side of the prop pulls more than the left, so we need to compensate. This pull is dependant on the angle of attack of the engine, and the throttle setting. It sounds like you've got a good balance for takeoff as you don't need rudder to compensate during takeoff.

Unfortunately, the right thrust fix for normal flight is working against us for inverted flight. It also is not really working for us on vertical lines as there is no angle of attack there.

I may have made a mistake on mine, as I've removed the right thrust angle on the engine. (Like I said, I'm probably in the minority). However, I wanted to be able to fly as well inverted as not, and I seem to spend about as much time near vertical and inverted these days as in straight and level. I'm spending more time inverted these days, and add that to the time I spend on vertical and near vertical lines, and you got what I spend right side up.

As I remember on the trim articles, not putting in any right thrust was not thought highly of by the author of the trim article. I've done this on my other builds, and haven't regretted it yet. I've found that I need to compensate for crosswind, bumps on the runway, and other things during takeoff more than asymmetrical thrust. It is also one of my arguments with my simulator.

It's all a balance between normal flight and inverted flight. You make the normal flight better at the cost of inverted flight. You make the aerobatic cabability at the cost of stability. Like I said, earlier find your level of comfort with things.

I'll try to find the article, but don't hold your breath. I was travelling through the airport and wanted something to read on the plane.
