RE: Spot On 50 Build log.
The gear from 3D Hobby shop that we are using has just about the same dimensions as the stock gear. I think they are around 140-150 mm high. Neither will accomodate 14" props with much additional space. However, there are lots of other choices out there...you just have to dig a little. 3DHS has a ton of them...I'm sure one will give adequate clearance. Maybe the AJ Slick gear.
If you get something taller just avoid sweep as the plane will tip over at the nominal CG.
