RE: How much power?
Thanks guys Sorry I did not respond sooner but I was out of town. Sounds like I need to pile every thing on a scale and get a estimate on my weight. I should be able to do that a get close to an empty weight. Should I do that without an engine and then plug in different engine weights to get a total weight? Seems thats all i can do seeing as how i dont have a stock of engines laying around. I am a slow mover nowdays so I will post the weight when I get it but it may be a few days. I dont have any pictures yet but will take some when i get closer to getting it finished. Thanks to everyone for all the information see ya later steve

How much power?
Hi Everyone This is my first post so I hope I have put it in the correct place. I have been in and out of RC for many years and have always built from kits. I am currently building an old Bud Nosen 8’ jenny. This is the largest plane I have ever built. My question is this. What power should I use? The kit was originally for a 60 two stroke. I was going to put a 91 four stroke on it but after talking to some of the guys at the Warbirds over Oklahoma in May they led me to believe that would never be enough. I have not finished it yet so I don’t know what its weight will be. Is there a general rule of thumb for how to power your plane if the weight and wing area is known? I have made a few modifications to the wing setup to make it easier to transport so I am sure it will be heavier than originally designed. I have always used the power recommended for what ever kit I was building (mostly 40 powered). I know this is probably a deep subject but any input would be helpful. Thanks Steve
