Anyone built a sig riser or riser 100? Wondering how the wood quality/cutting is and more importantly how they soar. Also how difficult to build? Been flying a radian and a homemade job but want something in a built up pure sailplane for thermal hunting that is responsive to lift, light weight, and c.h.e.a.p..Wondering about thermal abilities more than anything and building tips. I have built several sig kits(4*40, 4*60, seniorita, kadet mark1...)and all of them have been very straightforward with decent wood and great plans. Are these similar to their other kits in terms of building ease? Thanks for any input you may have.
