One of my favourite slopies is the Calypso Cobra.





This model is somewhere around 16 years old, still going strong and always puts a smile on my dial.

It's an F3B model and has been to the world champs in Germany back in the day. F3B models are intended to be winch launched, but these are rather brutal affairs and my Cobra has had more than a few repairs done to the wings over the years so I would not be happy subjecting it to the stresses of a winch launch. The wings are hollow and, if the leading edge ever splits on a winch launch, the result is a catastrophic explosion of the wing.

So, I wanted to get a bit more stick time on her over summer and thought about attaching a SLS (self launch system). There is zero spare room inside the fuse so the whole mechanism has to be in a self contained pod attached to the wing at around the cg point to maintain correct balance.

Had a hunt around and looked at some eye wateringly expensive set ups. I had pretty much decided on making my own when I stumbled on one a German chap had developed himself and was selling online as the Lifter: http://www.tecshape.de/index.php/en/product-dev-en

This was sort of what I was after, but had the disadvantage that it could only be used once, then it collapsed and had to be reset manually on the ground after landing. Not a biggy, but I figured that the Cobra is such a brute of a thing that it should still fly well with the pod raised which meant you could get maybe four climbouts from each...Continue Reading

I have been wanting to build a "classic" type glider for ages and finally settled on one that I have had my eye on for some time - the Ka-8b, the original of which was popular in the late '50's. There are actually about five different models of this glider available and I chose one made by Phoenix Models in Vietnam.

The model has a power option and can be set up for aerotow with the motor still in place. Makes a good ridge soarer also, so is quite versatile.

There is a useful thread on the model here at RCG: http://www.rcgroups.com/forums/showthread.php?t=2047990

The build was pretty straight forward and the kit is well built.

Did the maiden flight yesterday and the model performed very well.

Shot a bit of head cam vid. Just some low and slow stuff.

Really thrilled with this model.

Been flying my Birdie for a couple of months and it has become one of my favourite planes. Very convenient to haul around and quick to set up. I picked one up when Ming at Windrider had one of his free shipping deals. The model is primarily designed as a sloper, but I slipped a motor in to add a bit of versatility.

In the first part of the vid below the model is being flown in a landing ground behind the ridge with a turbulent 10kt wind blowing, which it handled well. Then out to the ridge for a spot of unpowered ridge soaring in 15kts.

Been having a lot of fun lately with my Polaris Ultra from ModelAero.

Maiden was a non-event and the HK Skipper proved to be a good trainer. On 4S the PU has gobs of power, although it is a bit rowdier than the Skipper. I did expect this, but it makes it a bit marginal as a park flyer although the bulk of the noise is created above about two thirds throttle, so I just give it the full welly at a bit of a distance from the huddled masses and it sounds OK.

Real easy to fly and great fun on the deck. A few of the guys in the States have been using them for FPV - not long range stuff, just hooning around at low level. They reinforce the hull (which already has a belly pan) and the PU can then can just bounce off anything that it grazes. ModelAero sell a drop in gimbal structure that just replaces the cockpit.

Haven't done any vids yet, so here's a retail one that shows how she flies - great model.

Well it's over a year on now and the Jazilla is still going strong. Had a couple of smack ups due to a POS UBEC and exceeding the VNE, but she's a pretty tough model to kill. I usually fly it out on the coast and at the club field, but sometimes in a local park that is generally deserted mid week.

Here's a short vid from a recent outing.

In the last blog entry I recorded a vid of some of the adventures I have had with my 7 year old EPP Eagle. I sometimes wondered how it would go with a bigger wing and the project finally made it to the top of the build queue.

Built a 2.3m Condor wing to go on the standard Eagle body. Bit of tuning to do, but it went well - off to the paint shop.

My Eagle is just coming up on 7 years old and still going strong after over 150 flights. This model would have to be one of the best bang for a buck purchases I have made. Makes a great park flyer and ridge soarer and can also be flown indoors. Also good for exercising dogs and small children

Just chucked a few bits of vid together to celebrate her birthday.

Well the DG-808S is done and ready for the maiden.

Overall I was rather impressed with the quality of the kit and it is quite a good buy as an "entry level" 4m model. I have made some additional mods and resisted the urge to "stick a motor in it". It has a tow hook installed, but I will mainly use it for ridge soaring. The decals are some custom ones I had made up by the lovely Callie.

So, here she is:

I am now the proud owner of a shinny Neos Light DLG.

It's probably wasted on me, but is a special treat and a great step up from my 9 years old Raven beater that I have been flying for six years.

The Neos really is a work of art and the light version (weighing 260g/9.2oz in it's underwear) has wings and tail feathers constructed with Carboline resulting in a material weight saving being achieved compared to a carbon weave. The product was developed by Vladimir's models and, with a double weave, produces a light tough and beautifully smooth finish: http://www.hyperflight.co.uk/product...CARBOLINE-SC90

For anyone interested in getting into DLG flying, there are some cheaper options around like the Versus from HK and several from R2 Hobbies that fly well enough and also double as fun light wind slopies (watch out for EPP terrorists, but). Here's a surprisingly good vid from those clowns at FliteTest that takes you through the basics - at least David has a good taste in models

I have become quite a fan of powered warm liner gliders as they give you a good bang for a buck being good fun as park flyers and also suitable for ridge soaring - maybe also some thermaling on a good day

Finished my Gliderman (Bird of Time clone) recently and had some great maiden flights with it.

Flying weight with a 4s 4,000 mAh battery and 60 amp ESC is 3.1kg (6.8lbs) with 472g (just over 1 pound) of ballast. In comparison my BoT on 3s was 1.7kg (3.7lb), but it was RE and a totally different ship.I used HS-81 servos on the ailerons and elevator and an HS-82mg on the rudder as I popped a couple of servo cogs on the servo for the rudder of my BoT landing in long grass. Set the ailerons with 75% differential.

Here's a vid of the maiden flights.

Here is my 3.2m Jazilla, a flying wing cooked up by one of my LHSs as a 213% variation of their 1.5m Jazz. It is EPP covered in lamfilm with (black) automotive vinyl and (yellow) Towercoat covering. Winglets are corflute and the ESC pod is from Windrider. It’s powered by two 3300 4S batteries in parallel and RTF weight is 5.2kg.

Just maidened it last weekend – here’s a vid.

I have had a lot of fun with the X-8 (see recent blog entries), flying in parks and at the club field and it was a pleasure to see how well it takes to ridge soaring. It's a bit of a brute with a flying weight of 3.6kg o/a of a lot of strengthening, but seems light as feather once the wind gets under its sails. The blended wing lifting body was computer designed for maximum efficiency and sure works well.

Well, I got the X-8 finished last night and today dawned bright and sunny, so it was maiden day – yikes.

Further to the previous two blog entries, I finally made it out to the coast last weekend and had some great flights with the Z1. Here's a vid - at the start of the vid windspeed was about 2 kts and the Z1 was the only model flying

As well as being a great glider the Z1 flies great with a motor pod attached. Here's a short vid of some low and slow stuff from the powered maiden.

Here's a great model that became available last year - it's called the Z1 and is a flying wing built with DLG tech and available thru ZupAir.

I took a liking to this model as it has a variety of applications being able to be hand launched or pinged up on a light bungee for thermal and aerobatic flying, is good for suburban soaring and light wind coastal soaring and can have a power pod attached.

Here's some pics and a short vid of it being bungee launched down at the park. The launches were only at about 60% capacity as I knew the Z1 would speck out on the vid at full noise.
