I'm building a Great planes .60 cub, and I have a few questions. As far a the coverings go, I know they reccomend monokote or something similar, but I think it is coverite that has the same basic thing, but it is actually fabric. I think it would be really cool to go with real fabric (I want to try to make it as realistic looking as possible, and I would think that fabric is stronger...), but it is something like 50% heavier. So I guess I want to know how that extra weight would affect the plane, and how well this other stuff actually performs. I am planning on using the os .91 4-stroke. Is there something else that I should consider? And do I need high-torque servos for any of the control surfaces? It did't say anything about it in the instructions, but I have seen much smaller kits that reccomend one for the rudder.
This is actually my first plane. Probably far from the best kit to start out with, but I'm going to take my time, and while I'm building it I'm going to buy a cheap arf trainer and get really good at not crashing. I was thinking about maybe the tower hobbies one because it is only around $60, and with a $50 .40 and probably under $100 in radio stuff (not going to need a second transmitter...) it won't be very expensive at all in comparison to how much it will cost to build this cub.
If anyone has any experience with this kit and thinks that there is something that I should know about it, please tell me.

I guess I also want to know about what props would work well. I want to find something that will work well in combination with that engine to make it fly better at a lower rpm. I really want something like the real thing. I know I'm not going to get 2000 rpm out of a little glow engine, but really high rpm on something like this would really bother me. What I really would want to do is put one of those 4 cylinder things on there, but that is both cost and size prohibitive.
