Default RE: Twin Somethin' Extra

Ron... She's a keeper! So far I've taken it out twice and have made a total of four flights. Each flight has been really smooth and it never needed any major trim adjustments. It ended up weighing 8.5lbs which is pretty heavy considering my single engine SE's are around 5.5.lbs. However, the twin is has a sheeted turtledeck and wings, two tanks & engines with mufflers, two throttle servos, a large nose block, about 3 or 4 oz. of lead for bablance, now has heavy duty Dubro gear and the weight of the extra material making up the nacelles. Whew! After putting it that way, I'm a little more understanding of the weight difference.

Since it's a twin, I always make long, controlled takeoffs and it always tracks straight down the runway with a nice gradual ascent. Landings are a little different..It wants to come in slow (or maybe it's me from flying the singles). I have to remember to keep the throttles up a little. I bent up the originals from a rough landing caused by too low of an airspeed.

In the air, it's just like any other airplane. Loops and rolls aren't quite as tight as the singles but that was expected. I just have to say the best part of this plane is how smooth it feels in the air, I really like that. I haven't gotten too crazy with aerobatics yet because I want a few more flights to test the reliability of the engine setup.

I never would have guessed it, but I could have gotten away with putting .32SXs on it rather than .25FXs. As it is now, it's a little faster than the singles with .46FXs but I thought it would have been a lot faster.

This was pretty much just a test plane. I'd like to build a larger one with .46AXs this winter. I learned a lot from this one and plan to do some things quite a bit different on the next one. Some of these changes are a single gas tank, larger engines, more flexible gear and some internal changes to the nacelles.
