Walter,
Don't worryabout the fuse being light, its made that way because by the time you get all your servos , batteries, switches install you will appreciate the lightness. In my humble opinion the plane begs for a small 26cc gas engine and the cowling is large enough to hide a side carb mount Zenoah G-26EI. I would never install a glow engine in this plane. The one thing you dont want to experience with this plane is DEADSTICK. If you go Saito, install the the Gas version of the2.20 and swing a three blade propeller.

Beefing up the fire wall only adds weight to the overall plane and degrades performance. You want the weight to come out around 12-13 lbs and the wing loading tostayunder
that of a warbird of the same size.I guarantee you won't like this plane heavy.The wings on this plane are beefy and very well put together, no foam, no fiberglass,all build up.
This isgood because they bear the load andthe firsttime you lower the nose at full power and the plane comesdown the runway at about 90 mph you will beglad they are strong.

What ever you do dont let air get under the canopy, you see the results above.All I saw was a tiny cut in theblack canopy trim and air gotunder and ripped the whole turttledeck out.
When the plane smacked the grass runway at full power thewingsdidnot break, the tube bent but the wings stayed together. This kit isvery well designed.

Go for it !
