ULTRACRUISER QUESTIONS

Q: Can the Ultracruiser be built as a Part 103 FAA compliant ultralight?

A: Yes.  If it is built without a canopy and electric start it will comply with Part 103, meaning no license is required to fly, and it is not required to be registered or inspected by the FAA.

Q: Can the Ultracruiser be registered, given an “N” Number?

A: Most certainly. If you choose to have electric start, canopy, and/or tricycle gear you will not be within the Part 103 rules, and you may have the aircraft inspected and registered with the FAA.

Q: What are the FAA Part 103 requirements?

A: Generally speaking the maximum empty weight cannot exceed 254 lbs, the vehicle can only hold 5 gallons of fuel, maximum cruise speed is 63 mph and stall speed is less than 28 mph. 

 

Q: What ½ VW engine options are available for the Ultracruiser?

A: Really any 1/2VW direct drive conversion will work, generally these are 32hp, 37hp, and 45 hp.  There are various sources for engines.  We generally recommend Hummel Engines and Machining owned by Scott Casler.  

 

Q: Are there other engine options available for the Ultracruiser?

A: We are currently working on a few different engine options and will have more information in the 1st quarter of 2021.

 

Q: Can I build just from plans?

A: Yes – our plans are 30 pages or 24” x 36” detailed sheets showing the entire construction process with many full size templates on the pages.

 

Q: How long with it take me to build from plans (scratch built)?

A: This is a difficult question to answer as it depends on many factors.  We generally tell new builders that it may take about 1000 hours to complete a scratch build aircraft. Building using our kits can save you lots of time.

 

Q: Do I have to buy the entire kit all at once?

A: No! We have the aircraft broken down into sub-kits that spread out the cost.  This also allows you the freedom to build at your pace and at your budget.

 

Q: Do I need any special tools to build the kit?

A: No not really.  General hand tools, cleco pliers, a few hundred clecos, and a pneumatic pull riveter are about all that is needed.  Any solid riveting is done at the factory. Take a look at the forum to see what others may think

 

Q: How much space do I need to build the kit?

A: A one car garage will accommodate most all building until you are ready to install the wings.  At that point, you will need to get to a hanger, or a larger building. We do not recommend you tie the aircraft down outside.

 

Q: Can I just buy some of the parts and hand-build the rest?

A: Certainly.  We offer various groupings of parts that we have found that are helpful to the plans builder.  We offer formed wing rib sets, bulkhead sets, welded parts, and various other components. Just check out the online store!

 

Q: Can I come see an aircraft?

A: Yes! We have visitor hours on specific days at the demonstration hangar.  Please call us as we may have a customer near you that would show you their aircraft.  If not, we can make arrangements for you to visit us.

 

Q: I am really tall / kind of big.  Can I fit into an Ultracruiser?

A: The Ultracruiser is capable of a maximum weight of 575 lbs.  (Empty weight can be as low at 254 lbs).  Pilots as tall as 6’2” have been able to fit into the airframe.   If you are larger than that, the H5 would be a better choice.

 

Q: How many Ultracruisers are flying?

A: Plans were first introduced in 2001. We estimate that there are more than 80 aircraft flying.

 

Q: How long does it take me to get a kit?

A: We generally have most of the sub-kits on the shelf ready to ship within a few days.  In the event that we don’t have a complete kit ready to go, we can get you started on one of the sub-kits, and ship you the rest when stock is available.  Please call us to discuss as stock levels change constantly.

 

Q: Can I buy an Ultracruiser Ready to Fly?
