I am sure it will be, the inverted GX31 should fit perfect. I actually started the DVII above and the 1/4 scale Sopwith Pup on the same weekend. I did both sets of wings. Now, after I paint the DVII, I need to start on the fuse for the pup. I am hoping to have them both completely detailed and ready for this spring. I doubt I will need to do a maiden flight on the Pup before detailing that though, I am using a Homelite 25cc on it and its a pretty easy plane to handle.
