  1. I have always been intrigued by the variety of flying wing and canard experimental aircraft ventures that were prevalent during and after WW2 in Britain. Some details of these are recorded in these two postings:

    I am rather fond of "wing things" **LINK** and thought it would be fun to knock up a flying wing in the form of the experimental ventures.

    I chose the EPP moulded Windrider Scout Bee as a base, so at least I knew the aerodynamics should work. The winglets were made from 2mm corflute sandwiched between two bits of balsa with the flutes and the grain at 90 degreees to each other. A Windrider pod and motor mount was used with a P-39 cockpit grafted on to the pod. Power is supplied by a 2200 3S battery. Covering is Solartex. The lower surface scheme was used on prototypes and experimental a/c to identify them to other pilots and to (hopefully) stop wartime gunners from taking pot shots at the strange shape in the sky.

    The model has just been finished and is ready for the maiden. I usually try and get the maiden in before doing all the finishing work, but am pretty confident that the airframe will fly well, so she's RTF.

  2.  Not sure If you are referring to the pics above or the album. In the album it would be the lime green coloured one, here's another pic - it's front and center.

    Very nice build by one of the USA visitors. He sold it to a local to save having to cart it home - it's name starts with a T. The other brute is also hiding in the background.

  3. Each year in September a group of slope fanatics get together at a place called Manilla in the Australian wilderness for a week of flying, drinking, line spinning and general slopey stuff. It's such a great site with such a good group of people that participants travel from NZ and the States to be there.

    The site has been developed by hang glider and parapente enthusiasts with astro turf laid and accommodation near by.

    The site has a splendid view and fairly unobstructed approaches which makes for a smooth airflow although landing out can involve a bit of a walk.

    As well a general slopers the strong lift also attracts a lot of PSS giders.

    I thought you guys might be interested to see some of the "down under" PSS builds at the slope fest that are recorded in this album: **LINK**

  4. We did discuss this in another thread somewhere, but I can't remember where. What actually happened was that the Do was doing a touch and go and hit a submerged object at high speed on the starboard side which caused the a/c to momentarily swing to the right. The pilot instinctively feed in a heap of left rudder which, due to the twin rudders and the relatively high water speed, caused the violent swing to the left. Took on some water, but was able to limp in to shore.

  5. Polyurethane glue in a canister will often give the appearance of having gone off from exposure to air, but there is usually a core of soft stuff left in the middle. Getting at it is the tricky bit. I use a hack saw to break through the mantle and have the building job handy to apply the oozing poly to. Once finished, bandage up the cut with masking tape till next time.

  6. 1 in 10000 odds aren't very good when it comes to the plethora of RC activities.laugh

    I was spotting for a friend one day at our club. He was using a JR 3810 radio which has the battery compartment hatch secured by a plastic catch. The battery used is a "button" type that has terminals like you get on small 9v batteries. The connection is just maintained by a slight bending of the terminals inside the battery bay when the battery is inserted. When the TX is held horizontally the battery compartment hatch forms a trap door and the battery hangs precariously above it, held in place by friction.

    So, he was flying along calmly, when all of a sudden there was a nasty "click", the battery hatch pops open and the battery drops out on to the ground at our feet. The model went into failsafe, which had been set up as a gentle circular turn and I made a grab for the battery. My friend held out the transmitter and I inserted the battery back in the bay and held it in place while he made a very hurried landing.

    He now secures the hatch with electrical tape!

    A 3d printed plane will deform if left in hot sun or a closed car in the sun .

    Sure will, I have seen some moderate examples at the club field - these two are a bit more extremesurprise

    The build is going well Martian - keep at it!

  8. I think it is a case of horses for courses when it comes to slopin' as the conditions will usually change markedly during the day with the wind usually picking up in the afternoon so it is fun to have a light wind model for some early morning sessions, but you need to know it's abilities and limitations. I often haul along 8 or 9 models to the slope and work through them as the conditions change.

    I love models like the Leprechaun and Sinbad as they have a lot of character, but do have their limitations. There are some similarly shaped "updated" kits around with reduced dihedral and ailerons that are also a lot of fun. One I like (available from Pichler) is the MotorSpatz which is a 2.5m powered model that performs well as a sloper and parkflyer.

    Here's a vid of mine doing a bit of slopin' in 12 kts - not a patch on the house of Woodfield's masterpiece I'm afraid as I was flying alone, so it is a "nutcam" effort.

    Just out of interest have you any idea of the location ?

    The vid was shot at Perranporth, Cornwall by John's long suffering and very talented wife. She does the editing too.perranporth, cornwall.jpg
