For a fellow RCG canard poster (Hi John), some graphs of a work in progress prototype DS section design.

Three graphs: 50mph, 150mph, 300mph

SR14-3e11 was my original effort with large -Cm
JM26 is the tried and very successfully proven D80 section
SR14-4e17 is my latest effort to reduce the -Cm. (I hope the fact that it goes + near the stall isn't disastrous?) If so, bring on the gyro!

Some time ago I got my hands on a D40 which stowed away, un-noticed by the Dynamic warehouse, on a shipment to New Zealand. Once it's whereabouts were established, I relieved Joe Manor of his stranded offspring and took it under my wing. I'm from NZ but I now live in the UK, but it didn't stop me from grabbing this golden opportunity with both hands, especially since my brother was about to come over and see me. He works for an airline so bringing a bit of extra baggage was never a problem.

I never intended to buy a D40 because until then I thought they were a bit of a gimmick. I can't sing their praises enough now though. After the painful build process, lots of swearing (think microscope and tweezers in comparison to a 60in build) and a ballsy move of cutting away much of the tail to rear mount the elevator servo as a mod, I finally threw her into the air for a front-side maiden. My first flight never resulted in a landing to test the brakes and elevator compensation etc... Too much mishandling had me spin her in from a 1/2 Cuban that I executed too low and pulled too hard. 1-0 to the earth.

Testament to how tough they are, a wobbly stab fix later I eventually got to DS her and I was very pleased.

She tracked like a plane more than twice her size and cut the DS circuit like a knife. It was only a light day, but good enough for a 125mph maiden. It was already evident she wanted more girth, I mean mass. I first built her with an all-up-weight of Joe's minimum...Continue Reading

I thought I might add this to my blog since i've been having massive amounts of fun getting to grips with it. The engineering quality is amazing too. I love it:

After chasing wind forecasts that turned out to be wrong and numerous walks up and down hills carrying an armfull of planes, I finally DS'ed my MCT for the first time on Friday 16-July-2010. Thanks to Graham Bridge for radaring my first flight. 194mph was the best I could manage. A shame to miss out on joining the +200 club but it's going to happen sooner or later. This thing practically flies itself. Rotors and turbulence - it barely even flinches.

It's finally finished. Last night I put the finishing touches on my new carbon MCT.

I built the entire plane in my lounge on my coffee table. The mess I made of the lounge was staggering (all done and tidied up again while my wife was away on business). Sanding, drilling etc was performed in the back garden. I also strengthened the wing seat area internally with carbon/kevlar weave and some carbon tow as well. Since all planes eventually end up blowing out the wing area, sometimes it even happens from perfectly good landings, so i've simply performed my first strengthening repair in advance.

She's all checked out ready to fly

The artwork:

New Zealand Maori inspired art. The graphics are from a 'Manaia' which is a creature with birdīs head, human body and fish tail, and it represents a guardian angel. In my example, the tail of the Manaia is not included - I don't intend my MCT to go into the sea, so I hope I don't need protection from that element . When the hand is drawn with three fingers, they indicate the balance between sky, earth and sea. Itīs a symbol of protection. The gecko is a magical creature, which is said to keep deseases away from the house in which they live. The sharkīs teeth motif stands for strength.

For illustration to a fellow RCG flyer, a repair I did last year, with the help of a more experienced flyer friend, to end all landing damage. It has certainly taken some punishment since:. (poor photo quality due to using mobile phone)

During a recent trip to my beloved home of New Zealand I bought a Reaper and brought a bit of NZ back to the UK with me. Just in case my wife reads this... I got married there too and that was the best bit!!! (hehe). When we got back I couldn't wait to get this thing built so I spent a lot of my spare time on it and thanks to the understanding of my lovely wife much of it was assembled on our coffee table in the lounge (houses aren't very big here in the UK, unless you're a football star).

This beauty flies like a dream. I'm stoked with it.

I'm not usually very good at keeping blogs up to date so don't be surprised if this is the only entry for ages to come...

An awesome DS day was had yesterday at Rushup, UK with some other RCG members including DSMan and Zimofile. Everyone except the UK record holder (Mark Abbott) chalked up new PB's. Mark's PB of 237mph is so spectacular that it's always going to be tough to beat and falling 10mph short at 227mph was downright spectacular nevertheless! For the rest of us it was onwards and upwards.

The following speed details are replicated in the Speed, Plane, Person, Location... DS thread: http://www.rcgroups.com/forums/showt...43385&page=112


Today's speeds (witness/radar gunner in brackets):

Mark Abbott:
Opus MCT 227mph, (GB/George Pilkington?)

Graham Bridge:
Opus V 185mph, new PB, (KS)
HP60 154mph, new PB, (KS)
