RC-feind,
The smaller Extra300 is from the House of Balsa kit..... 1/5th scale; very nice build and with an OS46Fx up front with the Tower pipe, it moves very fast.... it is a handful to fly but very exillerating. My guess is I will not have much of it left by the end of the season... I love to fly it fast and very low across the rwy. I have built two but am considering the GP 40 extra next.... I think the flt characteristics sound alittle more forgiving. That little HOB Extra can really move though.
