RE: !/4 scale WWI kits?
Regarding Flair kits...again these are designed usually for maximum stability for the average flier and should be regarded as "Fun Flyers- Semi Scale". Their Sopwith Pup for example is an excellent flying machine but even the fuse and wings are different scale from the original full size... the landing gear is much wider and lower than need be.
Not sure how their DRI measure up, but I would expect the same inaccuracies as well....
I assume we are talking about accurate 1/4 scale kits on this thread.
