Onex ($20K homebuild Aerobatic)

Unread post by RudiGreyling » Fri Sep 11, 2009 9:07 am

RVators,

Posted here since there is no SONEX section in the "Aircraft Type Discussions"

At anticipated $20K All inclusive with brand new Aerovee 80HP engine, engine accessories, instruments, propeller and upholstery! Just add labour and paint...
THIS small form factor, single pilot aerobatic airplane is going to be the perfect toy for homebuilders.
Man you even build the engine from scratch, and that Aerovee must be the best looking VW Engine on the market.
The form factor, price and versatility (Aeros) is going to make it a winner as a puddle jumper for weeked warriors and home builders.
80HP and one up should be more than enough in a single seater.

Still 1 year before we see an actual version (Oskosh 2010), but the interest are huge already. After the RV10, I am going to play with this one in my garage, so I have at least 2 years to watch its development.

Start Saving up home builders and wanna be builders! for less than R200K and some labour you can have all BRAND NEW nice toy

http://www.sonexaircraft.com/research/onex.html
Onex (pronounced “One-X”) is a single-seat aircraft designed to offer an even-more economical way to build and fly your sport pilot aircraft! The folding-wing design can fit into a standard 7’ garage door, and the wing panels can easily be removed for trailering at highway speeds. The Onex follows the Sonex Aircraft design and engineering tradition in offering a simple, robust, aerobatic aircraft capable of squeezing incredible performance out of lower powered engines.

Reserve a Tailwheel version for me please!

Aerovee 80HP = $6.5K (So that means 20K - 6.5K = 13.5K for Onex kit)
Rattex 912 80 HP = $17.250K (Means Rattex engine is almost 130% the price of the kit)

Rattex is more than $10K more expensive, and you still have to add accessories and do engineering to fit 912, new engine mount, new cowls etc etc.
You will also have a Rear CG problem since 912 is (15%) 25lbs lighter, and a radiator positioning and cooling problem (water vs air)
If you fancy yourself an aircraft design engineer then go for it. This is what Experimental is about. If not stick to the plans.

On a $20K project $10K is a lot, it takes it to over $30K, before you did any of the changes to fit a 912.

I gaurentee you Sonex will not do the 912 engineering for you, you will be on your own.
Maybe Sonex will do the Aircooled Jabi 80HP ($12.5K) engineering for you, they did it on their other airplanes.
If you really want to go the own engenering route, I guess Aircooled Jabi 120HP ($16.5K) would be nice, but then it would be a Rocket!

Nah rather stick to the plans with what they got (AeroVee) and use it as a toy as they intended, at the cheap price.

My 2 Cents,
Rudi

Attended the Sonex worksop in the late 90s
Have allways fancied their stuff

John Monet was sued by Rattex so he will never install a Rattex in one of his designs, wont give any assistance to you doing so either.
Sonex design tends to being nose heavy with Aerovee, best with 80hp Jabi, Onex probabaly wont have this problem

But I love to doodle design and build - so maybe its something I should do. Would redo an 80hp Rattex to keep costs down

Wow, this looks like fun! I will be keeping a keen watch on the development, can see one of those in my hangar =D>

Thanks for sharing Rudi!

Fly safe,

Still seems like a lot of effort for little gain. New mounts. New and longer cowling (to get the CG right). Longer gear (or a 5 blade prop) for ground clearance...

If you really don't want a VW engine, try this one instead:

Hmm, I'll take a stab at it.

Since it is not out yet, the Anticipated Design limits are +6 and -3G.
I might be wrong but I don't think it is going to be a competition machine, but Aeros for fun is the name of the game here.
I think if you really wanted to do Aeros for Competion, look elsewhere.

Even if you did start Aeros for Competition in this machine, you will very quickly reach its limits.
Hey but time will tell, I am only speculating on a model that is not even released yet, going on what Sonex has done before and their mission "Fun, cheap aircraft for everyday people"

Yip, but 2 seater still ahead slightly for me.... Am thinking Sonex is maybe a better start (or more doable) project for me than RV both in time, skill and budget required. :oops: :oops: :oops:

Yes watching this with great interest, I order some stuff from SONEX a couple of weeks ago and I am busy getting the work shop ready for the build.

:D :D

Did someone say Sonex ?? I'd be interested to see an electric one, Sonex does make electrics
too as far as i know. In fact they are one of the Leading contenders.

The sound of the prop, the smoothness of the motor aaaahh, It must be an electric !
