Bruce makes the best kit you will ever build, http://www.btemodels.com/venture.html . The Venture 60 is a very stable flier with good aerobatic performance. A sixty sized two-stroke, 70 sized four-stroke or electric will fly the plane very well. Go to the search function here on RCU type in the box { subject:"venture 60"}. Do not include the beginning and ending brackets. You will find a lot of build threads and good info.
