I am in the process of building a Sig Hog Bipe. I made a new firewall and moved it back 1 1/2" to accomodate a Saito 1.50. I have just about finished the fuselage except for the top rear sheeting. I left it open in case I have to mount my servos in the tail area to offset the extra engine weight. Does anyone have any building experience with this model? Any tips I should know about? It is a first run kit I bought back in '95. Are there any kit improvements since then? Has anyone else built an overpowered hog bipe? Thanks in advance for any tips you can give me...[img]i/expressions/face-icon-small-happy.gif[/img]
