I have this plane I have noticed with high G turns there is a little flex in the wings, I would say to anyone assembling this plane just make sure there is plenty of adhesive in the center section around the wing joiner,and center wing ribs and spar,inspect the joiner to see if it has any obvious defects its a easy part to reproduce with stronger wood or order another from Horizon.
I have really cranked mine around with no adverse affects, the plane is a easy flyer, light,and looks good in the air,the firewall seems fine with tri stock and plenty of glue,I did use some thin CA around the fuse formers in a couple of spots, since they looked a little light on adhesive,other than that nothing much else,its also taken some abuse on landings since it was my first sport/warbird the only thing that was dammaged was the cowl and mabee my pride.
as for replacement gear if I was to do that modification I would want to redo the mounting rails there light and really intended for the light weight gear that are provided, I fly off a smooth surface so they have served me well enough,if I flew off grass I might consider replacing them,the Lado electric models look interesting.
as of this posting I have been working on a semi scratch build FW190A8 ,I have also built several kits over the years,which doesn't qualify my as a so called expert but I would have to disagree with calling this model Junk, comparing it to a kit is a unfair judgement,but if you stand it side by side to many of the ARF's it holds it's own in looks as well as flying ability.
it seems to me alot of the time flight failure comes from slopy assembly and inspection,it seems that quite a few assemblers throw these planes together, not taking the time to look the plane over to make sure everything is tight and flight ready,and making periodic inspections to insure the plane hasn't suffered any stresses over the life of the plane,even kit built models need this to be done,no matter how well built.
