Default RE: Alpha 60

That's funny though, Evolution states their .61 engine for the Alpha 60 is factory run (break in) and adjusted so as not to cause new pilots an problems
I have set the plane up for medium response to begin with, center holes on rudder,elevator and aileron servo arms and control horns. The nose gear linkage, I left with the most travel. Not sure where the throttle linkage will end up, where ever it's not buzzing and gives me full range of throttle control, right now that seems to like less travel, but I don't like the bend it puts in the linkage.

Sounds as though your on a good track and you selected some fine equipment. Chris was quite right when he talked of factory settings being off. You see that line that the engine is factory set is just sales hype. Yes they can put restricters on the needles to get somewhere in range but the problem is its a physical impossibility for some factory on the pacific rim somewhere to preset your needles for your altitude, Temperature and humidity thousands of miles away for the very day you will first run that engine, can,t be done. There is simply no substitute for an experianced mentor not just in flying but operating your engine and all facits of this hobby.

Its a fact that 95% of the new folks show up with there shinny new trainer invaribly have far too much control surface throws set. While setting the mechanical linkage up you may want to keep that in mind. Even though you have a computer radio and it can be toned down electronically if this is done to excess it can present other problems one of which is poor servo resolution and neutral centering. Best to start with the basics (mechanical linkage) and things will go smoother on that first outing with less preflight tinkering (lost time).

Setting maximum travel on your nose wheel is indeed a mistake and one of the most common, even for some more experianced pilots.
Set like that will always result in the first takeoff roll meandering wildly back and forth accross the runway. Best if you set the nosewheel for minimum travel and the differance will be amazing, Even if it means that you cannot do a sharp 180 on the runway.



Enjoy
