I have one of these with a .58CD RCV engine mounted sideways. The plane flys fine, plenty of power.
The arf drove me to fits building it as things seem very simple but end up being a royal PITA.
a) the nose gear plate nuts and bolts are Impossible to get at unless you are a contortionist
with very very small hands. I ended up using sheet metal screws into automotive type
"speed-nuts" that I could hold with some long hemostats. I replaced the nose gear with
a double leg Fultz set-up as the suplied was too thin, especially with wheel pants
(which are very good BTW)
The wing joiner holes were drilled out for 1/4 dowel rod instead of the metal pins, they didn't seem like
they penetrated the wind panels deep enough to do much good.
I wish they had included strut covers for the mains, looks weird with wire gear.
Overall, not a bad plane for the money. Cowl and trim are really nice.
