The STICTION 1.7m "PSP" is the second in the line of this size of wooden VTPR model. I'm very happy with its performance and durability. Weighing in at 25 ounces she has a 7.3 ounce wing loading on a SB96V/VS airfoil. We are finding the more we fly them they are great fun with no worries of breakage. This is good news for a woody now days and the stigma of crunchy fragility is pretty much gone! Larger than normal flight surfaces and its low mass construction are nice attributes allowing the pilot to fly worry free performing close to the ground aerobatics or fun fly with all kinds of control to the extreme. Like the prototype ZEPPELIN these aren't fast flyers but are highly maneuverable and inexpensive to construct. Give a woody PSP a try, you'll like it...

Good Lift...

LEROYER Flys Again!

Giullaume (William) Leroyer is one of the worlds top Voltige Totale and VTPR pilots. There are other videos of his masterful flying on this blog. I have had the priveledge of knowing him and his dad Michel through email while building my personal SONIC 2.5 glider. And I have grown to have great admiration for their flying and modeling skills but also their kind hearts and willingness to freely help me and others in modeling.
This is a brand new video Michel took of his son while on vacation in June flying some classic French VTPR on the coast of northern France after a 2 year layoff from flying anything RC. Here are his comments:

"After 2 years expatriated in CANADA for work, I've never touch a RC gliders, For my first return in town I was really excited to fly again with my old Sonic 2.50m, just to know if I lose my level in VTPR, Finally, with my father, we were near to the Menez-Hom in Bretagne and the weather was perfect for the spot called "Le chateau d'eau." All the feelings were there... RC gliders is like bicycle, you can't forget it... Sorry for the bad quality of the movie, I'm going to do my best in two years..."

As you can see this is some fantastic stuff in the higher air speed realms which Guillaume loves so much and he didnt miss a beat! We often talk about "slow and low" VTPR which we also see beautifully done by other great French pilots on the Menez-Hom slope. Guillaumes style is a little bit different utilizing the full speed range of his trusty blue-flame SONIC. He has admitted to me that he loves the faster elements of VTPR as it is more dangerous and allows more precise flight paths low to the ground with a composite model. Another way he puts it - "I like speed, I like to fly on the edge and touch the grass and to do that faster as possible because it will improve the challenges and reflexes..." To him and this author this style of VTPR is the ultimate in thrill, danger and satisfaction.

Hybrid AIR-100h progress




The new 3m hybrid project is underway again. Received the new wing and feather cores. They are EPS styrofoam. Wing root will be 10.5", tip 4.5" chord respectively. Single servo wing panels with 1/16" balsa skins. The decision is also made for the tail feather servos to be installed forward of the virticle fin within the tail boom. This will be especially challenging to balancing this glider with minimal nose weight. Final wing and joiner rod placement will be determined by the balance point when fully mocked up on the bench. Fun times are ahead!

3.5m Foam AIR-100

A great video of Ludo's large 3.5m Air-100 in EPP being flown in Brest France. Here are some of his notes to me recently about the fabrication. This model looks like a lot of fun with its gentle and majestic flight characteristics making it perfect for low & slow VTPR. The roll rate is very good and is able to fly in a very small box. Very durable making a nice recipe for ultimate fun in a BIG way.

Caractéristiques :

envergure : 350 cm (environ)
longueur : 180 cm
profils : SB 98 VR/VS
masse : 3500g

Each wing half is 183 cm long (2 times the length of the loaves of EPP at GTI) and two 8mm carbon tube spars of D4 in to reinforce the intrados and the extrados. The trailing edge is cut so that its thickness is 3mm => just stick to it a flat carbon 3x1mm to stiffen the BDF and the fin. The whole is coated with liquid adhesive neoprene tape and taped to armed (roll width 400 mm: as you say he should not be missed when installing the tape ...)

The fuselage is also full EPP / carbon => 20kg/m3 density well enough given the present volume. The general form is made ​​with hot wire and then rounding are made with a cutter and coarse sanding block. Finally, a key wing carbon rod of 12 mm can be mounted quickly and easily all (not even the wings restraint, nipples centering at the trailing edge returning to strength ...

Classic Menez-Hom VTPR

.Video courtesy Poedras Pierre-Louis

Some great fun yet dangerous VTPR flying in classic Menez-Hom flying site fashion. Some of the composite planes flying here are the Sonic, Excalibur, Limande, Twister and more. All 2.5 meter size. Take special note how all the pilots line up and take turns doing their thing trying to match or out do their mates. More importantly there are no foam planes present. A sign of true and ultimate no holds barred VTPR! You get a real sense of friendship and a challenging experience versus just flying back and forth or alone in the sky speeding around aimlessly. VTPR truly is thee most comprehensive and fun flying style on the slope.
