How much power?
<div style="margin: 0in 0in 0pt">Hi Everyone</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">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).</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">I know this is probably a deep subject but any input would be helpful.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">Thanks</div><div style="margin: 0in 0in 0pt">Steve</div><div style="margin: 0in 0in 0pt"></div>
