Hello Everyone

First off hello everyone. I am very new to planes. Have dozens of helicopters and cars. But this is my first plane. I went with the mini se5 bi-plane. Kit was out of stock So I downloaded the plans and cut it out. I have a bunch of parts and think I have what I need. First prop was a 6 inch and seemed under powered. Airplane lifted off but nose dived and broke the prop. I have installed a 7 x 4.5 prop and seems much better. We have had somewhat strong winds lately so I haven't had a chance for a good test flight.

I’m no sure changing the prop effect the plane nose diving. The plane may indeed need more power, I doubt more power will effect the nose dive. Most likely the plane needs to be trimmed out but the CG may be off.

What size is that motor, kind of looks like a one i used to have. looks like a 300 if it is you could put a prop saver on it .
