Hi there Forum members,


Hows it going? This my first post here under the vari eze category. I have a lead on a set of plans for about $300. My question is this..... I was looking at the specs for the varie eze at airventuremusem.org which is the musem at oshkosh. On the specs for the proto type is says the following:


Empty Weight: 399

Max Weight: 880lbs.

Engine: VW 1834CC 62Hp engine


Normal range: 670

@ Cruise speed: 900 miles

@ 40%: ???


my question is this. Does this sound close to what those of you are flying? Also, I noticed on some varieze's they have pods on the wings. Is in the plans or how do people make these? what about a extra fuel tank?


thanks a bunch & happy Flying/building,

Those specs are for the very original VariEze Burt built (N7EZ) - that airplane is in the EAA Museum in Oshkosh. That version was never offered via plans. The VariEze plans allow you to build a copy of N4EZ (currently on display at the Udvar-Hazy wing of the Air and Space Museum at Dulles), which is the "plans built" prototype. The plans-built VariEze generally utilizes a Continental O-200 engine, with C-85, C-90, and O-235 engines also suitable for use.


Ideally, a VariEze should not weight too much beyond 600 - 625 pounds. There are some that are 750+, which is too heavy to be considered a two-place airplane.


A "general" VariEze spec might look like this:


640 empty

O-200 (100HP)

Day VFR instruments

Cruise 150 Kts

Top Speed 175 Kts

Landing Speed 65 Kts

Range 700 NM

Minimum Runway (Sea Level, Standard Day) 2500'
