The SIG Four STAR 40 or 60 are both great Semi semtrical airfoils and and can be set up for either stable flight or add in more throw on the control surfaces and this plane comes ALIVE!!!!! I fly mine with a OS 40 SF, but i believe this plane would fly well on a OS LA40 if your on a budget. The plane comes as either a ARF or a kit. One thing to take into consideration is that generly these semi areobatic planes are lighter and ar not as durable and not as forgiving to a BOO BOO!!!. My first plane was the PT-40 kit with a FX 46. The kit lets you decide on 2 different dihedreals. I built with the greater as they recommended with makes the plane very stable,I believe that if built with less, then PT 40 would do some areobatic manevers with no trouble.I really recommend this plane as i can vouch that this plane it built stout!!!! as i have put mine to the test. Welcome to the Hobby as i am fairly new and am hooked.
