ME- 109 rubber band size

I forgot to ask, what about the stock 5"prop that comes with the kit will it work?

It will work. It's definitely not the best choice. For fun flying in a large yard, it does o.k.

You might consider balancing the propeller. It's not hard to do.I'll be glad to explain how to. if you don't know already.

I have a 7" propeller from a sterling kit. Would that be better ?

My guess is that would be a better choice. If that Sterling kit was of a similar wingspan as the Guillow model, then that would be a good indication of proper size prop.

I think the general rule of thumb is to use a prop 1/3 the wingspan length. So, for an 18" wingspan, a 6" in prop would be the choice.

Just to add my 2 cents. If this is your first model it is absolutely the wrong one to build to learn to fly these things. ADW123 was correct in saying that the Cessna 180 would be a MUCH better choice. Low wing airplanes are more difficult to trim than high wingers. That is the absolute truth and there is no way around it unless you have an experienced modeler to help you through every step of the trimming process. So all of this talk of rubber and props and wash out is all very helpful and true but none of it will make your experience any easier if you start by building a low wing airplane to begin with. All of these models can be made to fly but many would need major changes for success. The Cessna 180 needs no such changes unless you are going for good duration but that's another story. I hate to be a pin in your balloon but I speak the truth from many years of experience in free flight rubber powered competition. I'd like to see you really enjoy your first attempt at rubber powered flight.

I used to build these planes in the 80s. And all of the planes that I built where all painted up real nice, and all of the details put into them. So when I went to fly them, they didn't fly very good at all. Mostly controlled crashing. So for experience in building these planes I have plenty of that. But now that I am older, I want to make them fly. Not for any other reason to see them fly. I was just looking for some tips here to help me do that. So I appreciate everybody's advice. I tried posting some pictures of my plane but it says the file is to big,or something like that. Once I figure that out I would love to post it.

I would recommend the Peck Polymer 6 inch propeller. Also I use the Peck Polymer Super Sport rubber 1/8 inch four strands or two loops.
