Im in the process of building a Rascal 40 and purchased a OS .40 LA to power it. However, Im really having questions as to whether Im going to be happy with the 40. Dont get me wrong, Im still pretty new to rc and im not likely to be trying to hover the thing, but i really dont want to have an underpowered plane. What do you guys think? Should I order a bigger engine? Ive already mounted to 40 so I guess i would need to stick with OS so the holes will line up. Please let me know what you think. Thanks
