Want to make the right decision,

OS1.6
Saito 1.8
Moki 2.1
DA 50

???? I have thought of all a bit, I am leaning in the direction of the OS. Any help or advince would be appreciated,

Anything but the DA-50. THe DA-50 is an AWESOME engine no doubt but the fact of the matter is that it is just too heavy for this airplane. Generally, I wouldnt use a gas engine on any model that is less than 1/3 scale, and I am a HUGE gas fan so beleive me I have a great reason for this. The main reason being that the trade off between weight of the motors leans strongly in favor of the glow engines around this size airplane. The DA-50 would have been perfect in the Kangke Laser 200 but is just too heavy for a 1.20 sized airplane. I am not sure of the weight of the O.S. right off the top of my head but I do know the saito 1.80 is somewhere around 32 oz. aka. 2lbs. and the DA-50 (though super lite for its size) is just over the 3lb mark. Plus you need another battery pack for your electronic ignition (more weight). We are talking about roughly a 1 1/2 lb. difference which means a lot on a 1.20 size airplane, if your looking to do 3D or IMAC practice. With the low weight the airplane will more than likely land a lot better too.

i have a magnum 1.80 on my cap/232-120 it is enough motor to make the plane fly anyway you want it to fly i am using a 20-8 prop..i flew the plane around with a 1.20 motor for a few months and that flew it to scale....brian
