Looks like I have 2" clearence using a 14" prop and if not I will install a 1/2" block or I do have a longer set of legs if necessary. I am not inpressed with the quality of this bird as every thing is just too lightly built for my type of flying to last 3 years like my old pattern bird. Covering is allready comming off, wrinkles in the covering, wimpy wing hold down bolts, not even plastic 1/4" like every one else uses. Ailerons were warped. I guess one shouldn't expect much for $175/$200 As light as this one is built I expect my 91FX will be pleanty to do the job. We will se how she flys Friday if I can finish getting her together.
