This ridge soaring glider just turned 12 years old. That's 275 in human years

It's a scratch build that was originally intended for bungee launched thermal soaring. I still ping it up on a bungee now and then, but she's carrying a few repairs from her long life and needs to hook a strong thermal to stay up. Here's a vid ridge soaring in around 15 kts.

I managed to get my mits on a Durafly Spit recently, like the ones HobbyKing sells, and did a PSS ridge soaring glider conversion on it involving alot of strengthening, a repaint and cockpit detailing. Had no idea how it would go, but was pleasantly surprised at how well it flies. Heres a vid of the maiden in around 10kts with no ballast. She should honk along ballasted up.

I have four Strykers that are designed to fulfill different roles:

This one was primarily designed for indoor flying, but is alot of fun to fly outside in confined areas.

Took my park flyer Elegance glider out to the beach the other day to see how it went as a ridge soarer - pretty freaking great actually. Wind was only 3-5 kts which was enough to keep it up and it was good to have the motor on board for back up. This model will fly in quite high winds so has a good flight envelope.

This is my Horten Parabola flying wing that is one of my favourite models. I have a fairly light outrunner set up in it so it is quiet enough for parkflying and is capable of thermalling too. I managed to source a pusher folding prop for it and have a lot of fun ridge soaring it.

The model is actually a Sif designed by the great Jupp Wimmer in Germany. Pic of him below with some of his followers. Also in that pic is a microlight version of the Sif. He has designed a whole range of models based on the crescent wing format.

Vid of my Canterbury Sailplanes Arrow ridge soaring glider masquerading as a Pfeil rocket powered point of defence fighter for the Luftwaffe in 1946. Wind speed in the vid was only around 10kts - with ballast the Arrow will fly in up to 30kts.

As mentioned in an earlier entry, I have recently got a Bird of Time operational and have been assembling an Elegance powered glider to complement it. I was rather impressed with the quality of the kit, accessories and instruction manual. The model was designed as a thermal glider, but I wanted to primarily use it as a warm liner and ridge soarer so it was time to pep this baby up (insert Tim the Tool Man laugh).



Main mods made were:
- cf strip glued to the bottom of the horizontal stab;
- sheeted the inside of the rear fuse with 1/8th balsa;
- inserted a 5mm square cf tube through the wing with 3mm c/f rods on the ends as the wing tips have dihederal. Servo wires encased in straws Ė see pic below;
- the stock wire and snake operating the elevator through a near 90 degree bend was an accident waiting to happen, so I replaced it with a small DLG servo positioned at the top of the vertical stabiliser, activating the elevator with a direct push rod; and
- fibreglassed the inside of the front section of the nose.



Power comes from a Mega 22/20/4 inrunner, with Hyperion 50 amp esc and 2500mAh 3 cell lipo generating around 300 watts.

Just finished it last night and did the maiden flight today. Flew great and I had a really enjoyable session. I was surprised how well it thermalled given the extra weight added by the strenghening undertaken.

Just to add to the pucker factor I shot this vid of the maiden flights.

Just a little vid I put together of my GWS TA-4K Sykhawk and scratch built Su-27 cruising around down at my local park.

Well work, wind, weather and wherewithal finally came together today and I was able to maiden the BoT. All went well, trim was almost spot on with just a smidgen more lead needed in the nose as it was slightly tail heavy - just fixed it with downtrim for the maiden flights.

Managed to squirt off a bit of vid - just cruising around getting the feel for it and practising some landings. She has a very good sink rate and is quite impressive on low passes. With only R/E control and a 3M wingspan you have to think ahead a few seconds, although having the twirly thing on the front makes the response pretty quick when you need it due to the increased airflow over the tail feathers which comes in handy for ridge soaring landings.

All in all, well chuffed and looking forward to some summer fun.

I have always had a hankering for a BoT as three of my flying buddies have them (two gliders and one powered) and they are great gliders.They are quite hard to come by in NZ as they are mainly built from kits or plans and you either have to go through all that drama or manage to snag a second hand one.

Finally managed to secure a second hand one that had been made from plans. Itís a motorised version, which is what I had been looking for, and required very little work to knock it into shape. My contribution was:
- a redesign of the electrical and ventilation system.
- white trim on the horizontal stab and blue on the bottom of the main wing with a racing stripe on the fuse
- BoT decal on the starboard wing, still deciding if I will do anything with the port wing.
- fibreglassed the inside of the forward fuse and fitted a cf strip to the all flying tail (she will be used for ridge soaring as well as thermalling)
- new securing method for main hatch.
- new prop and spinner

The BoT is no hotliner, but is a great thermaller and I am looking forward to some relaxing cruising around on calmish days and ridge soaring in lightish winds.

Anyway, hereís some pics of her RTF. Off to buy a white hat

I have been picking away at a few projects lately without making a lot of progress as I have been working hard and flying when I can, but have finally managed to get a few things out the end of the production line. This one was painting the underside of the Calypso Cobra.

It originally had the Cobra burnt orange colour on it to which had been added an asymmetric blue and purple scheme that I didnít really care for, so I decided to give it a make over - how hard could it be? Well it turned into a bit of a PITA actually with a fair amount of prep needed and lots of masking tape and the Cob was out of action for a while. Anyway, we got there in the end.

Itís important with a job like this to rebalance the model once you are finished. Checked the lateral balance and she was spot on. Had to add 1.75 ounces of lead to the nose to balance out the new paint on the tail and the 2/3 of the paint on the wing that was behind the CG.

All ready in case I get a tap on the shoulder for the F3B world champs. :lol:

Now just got to find some time to go flying.

A new addition to the ridge soaring fleet - a Reaper from South Pacific Models.
The Reaper is designed specifically for dynamic soaring and slope racing, so pretty much wasted on me , but we will try and do it justice.

This is my foamy slope soarer called an Arrow and manufactured by Canterbury Sailplanes in NZ. I have always liked the look of it and it reminded me of something from the drawing boards of Alexander Lippisch (designer of the Me-163 Komet). So when I picked one up recently I thought I would give it a bit of a do over and draft it into the Luftwaffe as a Pheil (german for Arrow). Its a fairly straight forward build. I just added a cockpit and some camo paint and she was done.

Evo Alula - fun little ridgey and flat land soarer, second pic with its older and uglier E-Alula sister.
GP Spirit - Beautiful thermal glider, also a lot of fun as a ridge soarer in light to medium winds.
Airsail Viper - Indestructable ridge soarer and combat wing - also have fun launching it with a high start bungee.
Fenix - conversion of an el cheapo chuck glider into a fun little indoor/outdoor flyer.

Well, hereís another one to cross off a very long ďto doĒ list Ė repairs and refurbishment of The Sting.
This ridge soarer has just turned 10 years old and itís a testament to itís builders that it has survived the brutal lifestyle of a ridge soarer for so long. It has been through a few owners and absorbed some severe punishment, but I hope its now somewhat restored to its former glory. Restoration consisted of finishing the rebuild of part of the wing (fence post!!), fibreglassing the tops of the wing with .75oz cloth and WBPU (two coats) and covering with Ultracoat and trim. Lower wing surfaces got a respray of black with white invasion stripes. All good fun.
This is a very nice looking and somewhat unusual model (7 foot wingspan) and looks a bit like a Scorpion that has been doing a bit too much DS-ing.
