Thanks Jon.<div>I am prepared to move the engine forward as much as needed.  Just trying to minimize the amount of tail weight I may need to add.  I wanted to try a 4 stroke and the 72 seemed like a popular choice and the same length as the saito 65.  I will try to balance it by clamping the engine on before I drill or cut the mount to see if I can balance it with the battery.  If a lot of lead is needed I will cut the mount and move the engine back as far as possible.  I can always add some blocking to mount the cowl ahead but I don't think that will be needed.  I can always fly without a cowl.  I like a little challenge when building so it is adding to the fun.</div><div>
</div><div>If I cut the mount I will try to remember to post a picture to get comments.</div><div>
