Tossing ideas around for several years now, I'm making progress with a 3660mm, ducted fan glider. Firstly, I have to refine and perfect a scaled down version with a less powerful (relatively) EDF. Whereas the 12 ft version will get an EDF with over 3 kg of thrust, the 6 ft 8 in version now under construction only has 500 gms. I have to compensate by lightening it without changing the relative dimensions.
First picture is to scale but several adjustable features allow for tuning. Mainly fore/aft balance and air flow with EDF adjustment and tail size.

Following the success of my first polystyrene fuselage build, Solo 1500/Eaglewing, I'm building another hybrid. This one started out as a ST ROC, electric sailplane with a 2600mm wingspan. It was a horrible thing for several reasons and not even a nice looking model. It surprised me one day though as it climbed away from a slope without power. I tried it with twin ducted fans over the wing and soon after, trashed all but the wings which were the best part. Three years later and after looking for the ideal fuselage design, I chose the Windex 1200 style and because I had some issues keeping things simple regarding the tail/power pod being too heavy, I've gone with the Eclipse 400 'V' tail with an EDF pod between the wing trailing edge and the tail leading edge.
The build involves making a PS fuselage which is strengthened internally using 2.5mm fibreglass or carbon fibre and externally using plastic covering.
The shape is laid out to scale on the computer and side elevation is printed. This is the template to cut out the polystyrene in one peice which is then squared up accurately, then cut in half to make compartments for ballast, battery, ESC, Rx, wiring, servos, etc. The two halves are then re-joined with components such as pushrods, strengthening rods and wiring for motor, then finishing with appropriate covering.
I finally got my cutting table online and cut the tail parts and also the rough for the EDF....Continue Reading

I've been wanting a Pulsar Biplane for quite a while. I've decided to use the Saito 90TS I bought for my Aquila AT01 in my new Pulsar which I now have plans for. I flew my original Pulsar using a Saito FA80T 13cc which had plenty of power so this new Bipe with a 1500mm (59") span should have no problem with the new 15cc engine. To the basic design and increase in size, I'm making several other changes to enhance what is already a great plane. Construction involves, polystyrene, plywood, balsa, carbon fibre and fibreglass. I anticipate little change in the relative ratios.

There are fragments of information about this aircraft. It's a FG ARF??? kit from China. I liked the look of this little plane and have ended up buying two. AT01-1 is being fitted up as an electric and AT01-2 has got a Saito 90-TS waiting to power it up. My aim is to complete both aircraft with similar modifications except for power source. It's 1/6th scale, wingspan-1700mm, Flying weight-3200gms.
20th March 2012. Have flown it but tried to slow it down for landing and stalled it. Even so, I managed to come out of with some damage to engine cowl and bent nose-wheel strut. Now, re-glassing and strengthening front and making a better engine mount as the ply one supplied simply crumpled. I should have done these things to start with.
22nd April 2012. When I started strengthening the fuselage I found that the fibreglass is very dry with very little strength like usual glass/resin combo. The paint breaks away from this surface so me being a perfectionist, it'll be a longer job for it to be acceptable. With so many other projects I want to get into, I'm really regretting I bought this plane but so much work already, I have to keep going.
13th June 2012.
I've made quite a lot of changes, mainly to do with strength. The formers were mostly 'tacked' with a horrible glue that doesn't work particularly well so I made new formers 2 and 3 and FG'd these in. These also incorporate a nice strong but light ply battery box so formers are custom made for this purpose. Other strength...Continue Reading

My first model build in 1977 was a 116" Elmira sailplane. Of course there is always a first crash. Mine was on maiden flight with too little tension on bungee and too hard a throw resulting in a stall just 5m up!
Other craft I have owned include, Alpha-H, Hustler, Hustler-ail, Hustler low wing, Flair Pulsar, Capella and Trident 2000.
22 June 2010. Just completed re-building an old Quiet Advancer, 2 metre sailplane which was given to me. Well, the fuselage was totally mis-aligned so I built a new one using the plans supplied along with the bundle of bitsnpieces. My aim was to build the best looking Quiet Advancer ever and do justice to the original designer, Rollo J McKinley.

11 March 2012. New Elmira Plans arrived yesterday. I've wanted to build a new Elmira for a long time. Finally, I'll get to actually fly a copy of my first radio controlled model....Continue Reading

I started designing my scratch built glider in 2005. I wanted a simple and robust 'eagle' shaped design to fly with birds of prey. Wingspan - 1860/6'1", Length - 860/34" I've made several attempts at a first test flight and on 13th Sept I decided to go back to the building board and make some changes. Well, a lot of changes!!!
12th Oct 2009. I'm increasing the size of elevator and rudder before I test fly again.
14th Dec 2009. Whilst working on the wings I've decided to add ailerons. I'm also setting it up with a 2.4ghz radio.
30th Jan 2010. Re-built the tail, lightening wherever possible. Also managed to get hold of micro fittings (.032 inch) for aileron servos.
2nd March 2010. At last! Completed the re-build which weighs in at exactly 700 grams, ready to fly including added balast. Main points are: 1. Radical tail re-build with bigger rudder working inside elevator and bigger elevator styled out to a wedge shape. 2. Ailerons added with micro, 4 gram servos in each wing. 3. 2 x 6 gram servos for elevator/rudder. 4. Longer front with a solid ash nose drilled out for balast compartment. 5. retained black fuselage but beefed up colours and graphics for front. 6. Underside of wings are covered in metalic bronze type finish which matches front graphics. See new pics. Next - Test fly.
20th March 2010. First test fly. After making my first landing on a barbed wire fence with no more than a damaged leading edge, I continued flying and learning. 1. Glide angle is what...Continue Reading
