I have a Enya .15IV and OSMAX. 10 that both need venturi ' s ... but I think it's rated .15-.19
I built one for a Fox 15 (with the extended LE & TE), I'm not at all happy with it. Maybe be better with the muffler off? The Fox seems to lack enough grunt, or maybe I need to fly it on lines shorter than 52'.
When all else fails, read the instructions! The leading edge is notched for the ribs at proper spacing, and the instructions tell you to use the instruction sheet boarder lines to initially square the structure up. A typical easy does modification for the Akromaster is to leave the leading and trailing edges alone and not trim them to length, and cut a couple of ribs from scrap to increase the wing span and wing area. Lots of engine combinations work well with this airplane, which is just another great design to come out of SIG over the years. Flies well without flaps. Built light enough with a 1/4" this fuselage and I'll bet a properly set up .061 would fly the thing! I hope to try that myself here someday. Good luck and have fun, Dan McEntee
Just picked up this kit to start moving into the big boy planes...nice little $30 buy from local shop. My question is there any actual plans for this kit other than the poster sized paper of illustrations to build?
