Beginning to get exciting on the hybrid. Spent the afternoon tracing and cutting out the Air-100 plugs on the trusty band saw. As they sit here they are 11.2 ounces. 50" long for a 3 meter version. You can really see the differing foam sections - forward 1.9, tail boom 1.3. Time to get out the trusty razer knife and start shaping and sanding.

QUARK 2m Aerobat
There is no mystery I love wood modeling. I can appreciate some of the innovative foam efforts but wood and carbon fiber bring big smiles. The new QUARK is one that makes me smile. Fred aka: Looping Fred and his mates in Ireland have come up with a beautiful laser cut design that should turn heads and bring lots of fun building and flying. She's a beauty...Go to Island Models to read more about it and download the free plans!

Slope VTPR is center-stage on M.A.N.
I am very pleased to announce the new
VTPR Aerobatics article by yours truly is posted on MODEL AIRPLANE NEWS, the #1 RC aircraft magazine in the world! Hats
off to Debra Cleghorn for publishing, the greater VTPR community including
Pierre’ Rondel of Planet-Soaring out of France. Steve Lange of
SlopeAerobatics.com and the long list of dedicated slope aerobatic fliers and modelers for
their contribution to the style.

to read the article.
The American VTPR scene is now on track to a bright and growing future of which
could not have been possible without the French European influence of such
names as Gerard Prat, Eric Poulain, Remi Le Besque, Benoit Paysant-Le Roux, Guillaume
Leroyer, François Cahour, Erwan Laurans and our own Dawson Henderson. These stalwart and
innovative model designers and pilots are who VTPR hobbyists such as
myself look up to for inspiration and example. The roots of VTPR is forever planted with such as these...
It’s been
quite a ride and inspirational being a part of the VTPR vision here in America the
last 2-1/2 years of which I’m very humbled. Let’s keep this train rolling and new models built and flying!
Good Lift…
Eric

The VOL-LENT 2.5 walkaround
I couldn't wait any longer to try out my new VOL-LENT 2.5 meter glider. Lift and wind conditions were minimal at best but I was able to get a few minutes time on the ship walking away with a very positive report. In brief you may be shocked to see the flimsy empennage but with maximum durability in mind for the design it proved very stable in flight. No flutter or veering line of flight was witnessed or felt on the sticks. I admit this uncanny approach had me concerned when drawing it up and while assembling but it is actually a really neat deal and it is very durable and lightweight for a crunchy.
Specs:
Span - 2.5m (100")
OAL - 1372mm (54")
W.L. - 8.5 - 9oz
AUW - 50 - 54oz
I have begun a build thread on RCG should you wish to follow and ask questions. I have lots to share in my discovery of what has transpired on this unique design. Also if interested in building your own VOL-LENT I'm happy to share the build details and templates.
Man & Machine Alchemy
Team BLACKSHEEP has done it again with some Very-Close-to-The-Edge human soaring accompanied with a RC wing and camera! Phenomenal video. This is pretty remarkable and not recommended for the average... A perfect case for watching rather than doing!

Air-100h template drawing
The fuse template drawing is adjusted for a 2" longer than stock nose moment and ready to make up a permanent template out of wood veneer. Profile will be transfered with a black permanent marker then the shape cut out. Its starting to look like something. Can you see it?

Charlie Richardson - Interview of a Legend
Though this isn't VTPR related it surely is a piece of important slope soaring history we can all appreciate. I have known CR for about 22 years since the heyday of slope MOM and 4 man slope racing when "fast and furious" plane banging was the norm. Charlie was instrumental during the 80's and 90's for developing some of the most iconic and high performance slope gliders in the world that have sustained the test of time even today. His designs included the Turbo wingeron, Renegade 60" slope racer, the Fun-1, Climmax HLG, V tail Blazer, the beautiful 80" Contender wingeron, Raptor, and the famous unlimited class Raider slope racer. Quite an inventory of awesome models that still impress and perform to a very high degree. I have a Raider waiting to be next on the bench.
I have also known CR in another and current pastime of mine called Vintage Motocross. He is the owner/operator/racer of CR High Performance Products that supplies top notch CZ motocross race bikes and performance products. As with his huge success in slope racing he is equally if not more of a champion builder and racer on the vintage motocross scene. His brand of CZ motocross engines are the fastest in the land! I have had the pleasure to work with CR building my own CZ race machines with nothing but professional service. In fact it was Charlie that helped propel me into VMX and CZ's through his assistance back in 2001 selling my pristine F3B Eagle sailplane. That plane helped finance my first CZ400 restoration that is currently being raced by its new owner.
Its been a pleasure knowing and working with CR on so many levels. He still enjoys talking about the old days on the slope revisiting his battles and winnings like an old pro he is. He still has a slight hand on the RC sticks with his kids but competition is reserved for the MX track and boy does he still haul the mail with that great fluid form.
Chip Greely is proprietor of the new CR Aircraft bringing to you the same legendary models Charlie produced and more new CR based model designs for the 21st century. He really enjoys the hobby and is currently developing some new models under the CR brand. Some of them include the current Contestant, Pretender, Climmax Elite, Savaron S and Obscure. I look forward to seeing these come available in the future.
Paul Naton did an interview of CR back in 2009 that recounts his beginnings all the way through his racing career and current professional status. Here is his podcast interview for your listening enjoyment. (let it load)

Limande 2.5 VTPR
Limande is another fantastic VTPR model of world class caliber like Sonic and Excalibur. Ronan Calloch out of France is its designer. He has shared with me the veneer wing construction and its very lightweight wing joiner consisting of a short blade connection. Wing panels with Ronans special technique weigh in at an astounding 325 grams each! Watch for more new news coming in about the Limande... A+

VOL-LENT 2.5m VTPR ship - Made in USA !
New "big ship" for the VTPR playground.
Yours truly with new first pics of the Vol-Lent 2.5m VTPR glider. This is a hybrid lightweight constructed glider. More info and video here.
Air-100h fuselage cut
I knew looking at the large sized blocks of EPP foam on this project I would be faced with a lot of shaving and sanding. I really enjoy sanding wood but not foam. It just doesn’t deliver a natural flow of progress and it doesn’t smell as good as hand worked wood. Kind of “lifeless”. So I spent some time making up a pair of templates to be able to hot-wire cut the shape. You will notice by the glue lines I combined 1.3 and 1.9 weight EPP foam in order to attempt saving weight on the tail boom. The frontal area is heavier 2” thick 1.9 material laminated from the wing root forward. Gorilla glue was used to combine them. GOOP cement was used to attach the tail boom foam to the frontal foam pieces.
Attached the templates with 3” long drywall screws being careful not to over tighten and strip. A concern was what would happen when the wire reaches the GOOP glue line. I angled the wire slightly to attain a knifing action in this region but low and behold the wire sliced through the goop as if it wasn’t there. It has been over 20 years since I last cut foam so I was pleasantly happy with the results. Next task is to cut the side profile.
