Piel Pinocchio: The history of the Pinocchio, not unlike many other vintage airplanes, is incredibly hard to follow. The CP.10, CP.20, CP.90, CP.210, CP.211, CP.212 and CP. 215 were all named the Pinnochio and some were vastly different airplanes.

Technically the story of the Pinocchio starts with the CP.10. In 1948 Claude Piel, in his ambition to begin designing airplanes, built the CP.10. The airplane was significantly based (okay you could say copied off of) the Mignet Pou du Ciel “Flying Flea” and was powered with a Ppinsard 25 hp two cylinder opposed engine. While the first Pinocchio was successfully flown, it was a short lived success. 5 hours and 30 minutes to be exact. The Pinocchio didn’t quite make it to six hours of flying time before it crashed with Piel at the controls.

Abandoning the strange design of the Pou du Ciel, Piel started a new design from scratch. The CP.20 bore the same name but the similarities stopped there. The new design was now influenced by the Spitfire. But scaled down to tiny proportions. It had an intricate wooden elliptical cantilever wing which would turn out to be Piel’s signature design. Up front was a whopping 25 Volkswagen produced horsepower. The tiny cockpit seated only one with a handsome bubble canopy overhead.

The new CP.20 turned out to be quite a successful design and Piel immediately published plans for it. The CP. 210/211/212/215 were all variations of the original design with different engines. Salmson AD9s and...Continue Reading

I recently bought an estate sale lot of rc planes and equipment. Attached is a plane that i cannot identify. It needs a new firewall and I have an engine for it. Its probably pre 1980 since the servos are futaba and have a square piece for the control arm to attach. Its an F14 USS America designed for an engine with propeller up front. It has air retracts. I would like to get drawings so i can make a new firewall. Any help identifying it would be appreciated

A few months ago my GWS pico Tiger Moth sustained an ugly Right Wing Crash because I erroneously took out almost all of the wing dihedral and was stupid enough to hand launch it and it slipped into an inverted flying position. Fortunately, I was able to recover it in time and had the model flying right-side UP again but, the landing was not good and Right Wing ripped.

My efforts of gluing it back was amateur like by leaving the wing in a position while glue was curing that caused some sort of wing distortion (Wash-In) instead of Wash-Out, definitely the two wings not matching for sure. I made sure that the wing dihedral was placed back by gluing an Aluminum short Tube at the bottom of bottom wing, however, during in-flight observations, the Tiger Moth was observed to stray (slide) to lean towards the Right (a gentle stall) while mid-flight. Correcting this was no issue by applying a slight down Elevator and of course a tiny amount of Left Rudder.

However, all of this has caused me to re-think things as my Tiger Moth is no longer "Hands-Free" type of flying and you have to watch it carefully. I have taken steps to correct the Wash-In and settled using some home made tools (Large Clamp with heavy magnets) to pull down the rearward bottom Right Wing to at least match the Left wing.

No guarantee of the results but, I just hate breaking up the bottom Right wing again to provide the correct amount of Wash-Out and the glue etc...

Everyone that has seen it fly recently with this wing issue says it still flys majestic but, guess who has to correct at the controls!

Has anyone seen or have a Alitalia Cap 232 with a 73" wing. All i see is a 80" wing . Looking for the manual for this place. I believe it is a Hangar 9

The wing profile is enough to give you headaches, double curved with drooping leading edge, a bit like the Concorde . There are no two identical ribs from root to tip.

Piel Homebuilts: Today Richard VanGrunsven has made homebuilding aircraft a very reachable goal with Vans aircraft. Of course Vans has a single seat version, two seat versions in both side-by-side and tandem variants and a four seat version. While that seems like a neat modern idea, a little french company actually had a very similar lineup a long time before Vans.

Claude Piel’s first particularly successful airplane was the CP.20 Pinocchio. Even being the first airplane in the Piel lineup, it carried the signature design feature. All of the Piel airplanes feature a complex elliptical wing not unlike that of a spitfire. The little single seat Pinocchio had a tiny VW engine up front which made it a nice flier. About 20 CP.20s were built with a handful of engines including one powered by a Salmson AD9 9 cylinder 40hp radial. (I can’t find any pictures but it must have looked awesome)

With the success of his first design egging him one, Piel designed a series of aircraft which may be the most popular french homebuilts. The Pinocchio was the single seat version. Next up was the Emeraude which was an enlarged Pinocchio with two side-by-side seats. Then came the Diamant which was increased in size yet again allowing for four seats. And finally came the Beryl which was the same size as the Emeraude but seated two in tandem. His plans also included nosewheel options in some cases just like RV does today.

It’s impossible to add up how many of Piel’s designs have been built,...Continue Reading

Heat sinks went in on

May 20 & worked well for a few months. Then came another case of a screw coming loose, the encoder going out of alignment, & the motor stalling. It quickly overheated & melted the PLA, feeding back into the stall. The heat sink was initially only slightly warm. The good news is the heat sink quickly got hot. It definitely took out some heat. The motor cooled down more quickly than it did without it.

The lion kingdom stopped using PETG because it's heavier than PLA & it requires enormous heat to print. The melted PLA has never permanently killed it. What's really needed is a screwdriver which can tighten the screws in the field. Those screwdrivers are gigantic.

There are some really ignorant individuals who frequent forums. The fact that they get banned from other forums - doesn't seem to change their attitude or ways.

You try to accommodate - you go the long road to accept their way of doing things - pointing out that their way is theirs and others have their ways .....

Its a wasted effort .... they keep plugging on ruining good threads - oblivious that literally no positive replies to their self-indulgent posts and videos ....

I understand that the larger a forum membership gets - the likelihood of such idiots increases ... but it still destroys good threads and makes for moderators headaches.

Anyone reading this - I am sure know exactly which idiot I am talking about ....

Lumenier's Double AXII FPV antenna is able to effectively more than double the gain of a standard AXII 2 antenna from 2.2 to an incredible 4.7dBiC. The results are close to a patch antenna despite providing omni-directional high gain!

Dogs have been owned and through genetics/breeding you have the 100s of breeds we have today...

The cat? Not so much. Relatively a new comer to indoor living, it's more of an arrangement. You hangout and kill of the rodents and I will give you a place to stay and food. Other than that with the exception of a few breeds they are the mammal version of a shark.

It wasn't all that long ago if you were found the be the keeper of a cat they would build a fire in your honor and roast YOU for being a witch.

A feral cat and I'm talking house cat size could tear you up bad if it had a mind to.

I was in the yard with my morning coffee, my cat likes to sit with me and it hit me, I'm harboring a midget mountain lion...

Top is my cat Goose, the bottom is a picture of Messi, a mountain lion living as a house cat. I hate to say it but Messi is the more domesticated cat.

Grumman Guardian: The Guardian may be one of the most aptly named airplanes in history. Built for anti-submarine patrols, the Guardian was built to be the coastal guardian of the US.

In 1945 Grumman had just completed a new torpedo bomber called the XTB3F-1S. (I know, catchy name right?) The XTB3F-1S had initially been designed to have a big radial up front and a jet engine in the fuselage. But when it became obvious that the jet engines would never be delivered on time, they scrapped the jet portion of the project without ever having used it. The resulting airplane was a two seat, side by side, R-2800 powered torpedo bomber that could carry 4000lbs of explosives.

Just as Grumman completed the testing, the Navy changed its mind and decided they didn’t need a new torpedo bomber, they needed a new anti-submarine aircraft. Since the Guardian couldn’t carry all of the equipment for this task, the “Hunter/Killer” pair was born. In one of the coolest adaptations of a military airplane ever, the Guardian was adapted into two very different airplanes. The AF-2W “Guppy” was the “Hunter” and carried an immense radome underneath it with sub-detecting equipment. And the AF-2S “Scrapper” was the “Killer” which maintained the original bomb bay for carrying anti-sub explosives.

As the “Hunter/Killer” name implies, the two airplanes would operate together in a team. The “Hunter” would fly along with a “Killer” in tow and search for subs. If one was found, the “Killer” would move in...Continue Reading
