Hi Ryan
Yes the 1.70 will fly it fine with a 19-11 or 19.5-11.5 no problem. The plane should build 10 -10.25 pounds no problem with a 1.60 even.
Yes, I still love the Quest Too. But I must Admit it`s my favorite too! .But this is a generation apart built on the Quest platform architecture so,think of it as the Big Sister
When I was designing the plane I loved the look of the E model verses the Glow on Paper But, Now I think I like the Glow

of course it looks even better in the nose when the geometry of the contra spinner is added on. The production E model will have the paint tweaks like the larger green canopy so the E model will get the spa treatment soon as well!
Brett will be flying the glow version at the Nats so we will see it in competition soon. The size of the model Suits Bretts slow close style superbly.
