The fuselage strut reinforcement is a big one. Another is reinforcing the landing gear block. I have had to straighten the landing gear several times until I added the Bennett Built landing gear reinforcement rods. I also added a hatch on the bottom of the fuselage just behind the firewall to access that area easier. My electronic ignition is mounted there above the fuel tank. I built a bracket to hold it and it is zip tied there without any foam around it so the unit stays cool. I think this was most of the mods. There are pics throughout the trad of most of these. If you need some specific pics or more info send me a PM and I will help all I can. Also look real hard through the transparent covering on the wing at the ribs and spar webbing looking for shipping damage. Several people have had damage. I sent the 1st Rascal back I received for damage there. When I took the film off my current Rascal to do the flap mod there were several ribs and webbing that has cracks but nothing was missing so I was able to simply CA everything.

Now don't get me wrong. The Rascal 110 is an awesome plane. It is however an ARF and suffers from some of the quick build techniques that many ARF kits have for example running the grain on the spar weds the wrong direction.
