thank you all for helpful answers, i finally went for a Saito 45S. but when i opened the box yesterday, the manual said it's best suited for 25-30 class 2-stroke!!. do i really have to send it back in exchange of an saito 50? for me it's very important not to overpower the plane, cause i want it to behave naturally. therefore i was a bit afraid to order a saito 56, and even a 50. i've done a few searches on the 45S, and it seems like it's out of production. why? this is my first real plane with an engine installed, and i guess it wil be around for some time. therefore it's important that the engine can handle take-off's in the snow (live in norway)etc. so: do i have to replace it or what?

khodges: sorry to hear about the crash. try to dive into your friends next time you fly together, maybe the outcome willl be somewhat different then? i don't know. regarding the dihedral, i built the wing after your directions, and i asume it will be perfect for semi-acro-flying when time is due for that.

another option is to wait with this engine until [link=http://www.udisco.com/hobbies/pics/012023.jpg]this[/link] plane is finished, and buy a new saito 50 for the Kadet MK II? with a high wing acroplane like this a little extra power is welcome, or what? it's a pilot california-28 according to the manual best supplied with a 19-25 2 stroke. maybe the 45 will be to heavy (484g w/muffler).

ok, thanks.
