What Determines Max Gross on Our Planes


Joe Hood
 

The original Q2 shows a 1000 lbs max gross with the GU canard and the 64 hp Revmaster.

I've see Q200s with 1300 lbs max gross.


I'm guessing this is a play between horsepower and change to the LS canard. But is there a formula for that?

 

My plane as a 75 hp Revmaster with the LS canard and the former owner stated 1200 lbs max gross.

This should answer most of your questions: Q-talk 129 - So What Is Your Gross Weight?

Have you flown your plane yet?

Flying it back next week with my CFI. 

Thanks!

Do you have confidence in your CFI? Does he/she have time in type? There are plenty of instructors out there who think "they can fly the box it came in," until they see their first tiny homebuilt with dubious wheel alignment and one brake that pulls way better than the other. Just be sure your expert is an expert. This is from a guy who used to do friends' test flights for fun when I was in my 20s. Now that I am in my sixties, forget that!

Joe,

Welcome to the fold!

I certainly don't want to sound "preachy" since I don't know anything about you (you and your CFI may have 1000+ hours in a previous quickie for all I know). So I will merely state that the Q2 has an abysmal first flight safety record, so please use all of the resources at your disposal. Be especially careful if you intend the first flights to be with two people aboard a VW powered Q; they are limited by power loading.

Personally, there are a couple things I would independently verify before flying but you may have already done them.

Feel free to call/text me if you ever want to chat (just subtract 1 from each of the numbers below):
7-2-9-6-9-1-5-10-3-10

Blue skies,
Michael

I have 75 hp revmaster, LS1 canard, and I have max gross weight listed as 1100 lbs. My empty weight is 630 lbs, with an aluminum crankcase, which adds about 15 lbs. I've flown it at 1100 lbs and its a noticeable increase in take off distance and pitch sensitivity at max gross weight, especially because 99 percent of the time I fly it solo. As you test it with added weight you'll be able to determine your max gross weight. No two are alike. Hope that helps you.

Flying a newly acquired experimental of any sort on a cross country is not prudent. Let alone doing so if neither pilot is qualified.  

While inconvenient, trailering it is the best way to get both the plane and you home safely.
Learn the airplane and to fly it at home - baby steps.   History is on the side of caution.

Hi Joe,

More of the same from me. I have first hand experience with a buyer that decided have his CFI assist him with destroying my Q2. I am a CFI so I'm not bad-mouthing CFI's - only noting that a CFI is not typically well prepared for this type of flying. The transportation alternatives never look very appealing until you are standing over a torn up aircraft being forced to use one of those alternatives before starting on the three year reconstruction project.

Happy to talk more about this if you are interested.

Many of you may remember my experience bringing mine home from California to its temporary home in Arkansas; then Texas after that.  If not, feel free to watch some of it:  https://youtu.be/KnJPErafPu4

Joe - I did what you are doing; grabbed a CFI and had him fly with the owner/builder.  I grabbed a very experienced tailwheel instructor, that I had been flying a Husky and SuperCub with, and he studied every document he could find about the plane, as did I.  We both flew out to California with no expectations other than "let's see how it goes".  My CFI flew with Jason Skiby to get the sight picture and other information that could be passed along.  Skiby obviously did a great job.  Then the CFI was confident to fly solo and get a feel for the plane.  He flew out to do maneuvers and then did several low and slow passes to get the sight picture, power settings, and feel down.  After a few landings, I think we were all pleased and impressed but confidence obviously comes with more experience.

We then made the decision to fly it back.  All went well.  This time of year with two in the plane, definitely be aware of your density altitude, W&B, and at each airport know where on the runway you will abort the takeoff if something is not right.

Can't wait to hear how it goes with your flight!
