Never been really interested in 3 D flying,but my mate was building a model so thought I would give it a go.
Built a Yak from the scratch built foam forum,think it was a leadfeather posting...anyway built it out of 3mm depron with carbon rods and flat and kevlar wing supports.
Well I can say that it has been very interesting trying this 3 D flying. Have mastered a few moves but by no means an expert.
The guys that do all the demos I have to give them credit as they are aces.
It is getting a bit worse for wear now so will build another to replace this one.
Plane wt.169 gms.34 in w/s, blue wonder 1700 kv with a 8x3.8 sf prop.10 amp plush controller and 2s 450 mah Hyperion G3 battery, 3X HXT 9 gm servos
Plane hangs on 1/2 throttle and will just climb vertical on full power.
I have decided to continue with 3 D flying as it really brushes up ones skills for other flying.
A 5 min walk to the park, fly two batteries [16 minutes]then home.

Spent the day at one of our annual flying events.It is the Warbirds and classic Scale flyin,held at the now disused military base in Christchurch NZ
A good turn out of A/C and pilots.
Most A/C where military and a few civilian where represented in the line up.
Weather started very cloudy then came out sunny and windy.
Flying took place most of the day ,there was always an A/C of some kind in the air. A few pics here to give an idea of what was on hand.
My Tomahawk EYE was in the air for three flights.Turned out quite windy with very rough and turbulent air as the day progressed.
Over all a good day out.

After these few posts thought I would add a bit about myself.
Married with a very good wife and two growen up boys and one daughter inlaw.One a teacher and the other a Computor engineer and the wife a banker.
I am a licensed and rated aircraft engineer working for the Canterbury Aero Club in Christchurch NZ....we own a fleet of 36 aircraft. These are for the members but also another part of our operation is the International Academy of Aviation which is an International Pilot training facility.We lease our A/C to the Academy for their training.On an average we fly 20.000 hrs a year.
I help the other 5 engineers if and when they are busy but most of my work is in the rebuild, accident, hanger rash area.
A few years ago decided to specilize in the fabrication area,which is an area I enjoy as there is a great lot of satisfaction in the finished job.
We have a whole area that is used for this work and have now rebuilt 7 A/C in the last 6 years.Two twin engine Partenavia P68,4 Tomahawks,doing the 5 th one now.Rebuilt the wings on a Cessna 172 H.Put a whole new bottom in a new Piper Warrior.Rebuilt wings and tail plane for a Piper Arrow. Reskinned the wings on a Robin 2160 and all the other wee mishaps that appear along the way.
A good part of this work I am by myself all day,making all my own decisions and planning my work.
Over the last few years have been doing all the fiberglass work as well. My hobby part of the work that I was able to bring to the aero club we I started.I make all our molds, them fab all the parts we need. Also handy for models.
In all a good life, enjoyable and rewarding,with plenty of challenges.
The hangers are handy as we use them to fly our indoor models in when the Aircraft are all out.
My little hughes 300 chopper has done many hrs in the main hanger.

Some time back a good mate of mine tried to convince me to have a go with an electric model. He was into them and told me to give it a go..So I started to surf the rc groups e power sites and learn as much as I could...After IC for over 35 years this was something very strange to me.
Anyway started to get an interest in a foam CB float plane on this site.http://www.rcgroups.com/forums/showthread.php?t=954868
This would work out fine as I could now head off to the lake 5 min from home.[where I use my RC boat]
I didnt like the undercamber wing so I hot wired a full foam wing.The rest of the plane is out of depron with carbon fiber push rods.
Finally had it all done so off for a test fly.Well I can tell you flying a 365 gm model was a heap different to a 9 ib IC model.
Started off 3 channel but hated that so in went a 4th servo and cut out ailerons.Now we have a neat little plane.
The set up I have in it is a 1700kv blue wonder motor, 7x5 e prop,18 amp plush ESC.Zippy 1300 3c and 3 HXt900 servos.
This is now over 12 months old and last had it out to night [7 April]]after work.

This model is now 41 years old... I built it when I was kid about 15 yrs old.No plans ,just out of the head and if it looked right then it was.A couple of years ago we bought it out of retirement as we now have a very nice lake 5 mins walk from our new home. This lake is so nice decided to take the boat down for a spin.would you believe it, the wild life down there dont even give a hoot that the boat is on the lake.
Boat is 25 in long ,wt 3.5 ib and now has an OS 25 FP mounted after replacing the OS 10 ,so you can see this thing is fun.



But this has me deep in thought as I was sitting out in the lake after getting the boat ,I could see my float plane here. Ah one problem, the noise of the ic engine on the big float plane. The boat is fine as it is down on the water and the noise you cant hear from the houses.

OH boy so what do we do. .... more to follow.

This has been a very long build.Getting to the end now and it is coming out good. Had a few problems early on and the project has been shelved several times because of these.
Painting and panel lines are what I am up to now.Had to send to the USA for the chartpak tape and was helped by a very kind lady who sells the tape for other hobbies.
Could not get a jap pilot in full body so I managed to get part body and I made the rest out of blue foam .In my views he looks cool
Building an enclosed exhaust and muffler system.Spring air retracts.robart oleos and scale wheels,fiberglass gear doors.
Will post up dates as they happen.

First test flown in May 2007. and built over a period of 3 years. Now has 25 flights in the log book.Modelled off one of our fleet of trainers that I rebuilt.It so happened that as I was finishing the full size ,the model was close behind so I did it the same paint scheme.
It is 1/6 scale 72 in w/s, 9 lb and powered by a OS 46 LA.
It started off as a kit that is manufactured here in NZ and I did the undate mods as I went along.
The kit was quite good as a whole but when working on the full size I could see lots of changes needed to make it good scale.
The model is covered in oracover and the panel lines are done with the covering.All the trim is cut by hand but the club sign on the cowl and tail are computor cut.
Nose leg has been modified with new mountings and fitted in the correct position as the kit had it 34mm to far rearward. This made ground handling a real pain.[and it just didnt look correct]
Barbie is the correct scale and she flys it very well. I made up a scale head set for her and she just loves that.
Later I fitted a landing light in the cowl and that runs off a 9v battery through two resistors and a micro switch and micro servo.
Flys quite fast at full throttle but slows down nicely for scale flying.
Take off run on half flap, just like the full size. Landing on full flap very stable and positive.
Over all a really nice plane to fly and I use it when ever I can,which is not as much as I would like.

Often looked at this plane in the catalogue and dreamed about it..after one of my other planes was written off I just had to have this kit.
Both my sons where in the USA at the time so I asked them to bring it home for me.Well here it is and it is a blast to fly.
38 in span OS40LA power.After having a good look at the plans there was quite a few mods I was going to do.First off didnt like the banded on wings so that was to be changed ..
On construction of the wings I changed the mounting areas and fitted in anchor nuts so all the wings could be bolted.
wing struts are also bolted together as the orginal was only in a slot in both wings.
Side mounted the engine and built a fiber cowl
oracover for covering ,built and tested in 2004 and flowen ever since.It now has several hundred flights to its credit.
At our last flyin of two days this plane did 3.1 hrs flyin.
I absolutely love this machine,it is a blast to fly.
If anything ever happened to this plane I would sure as build another.

Another model that has had a heap of flying...First built and flowen in 1995.modelled after a full size here in NZ....44in span and powered by a OS 25FP..It is still flyable but having a rest at present so I can fly others. Done over 120 flights and 13.94 hrs
A very nice wee plane to fly and convenient size to pack up and take away.
Balsa construction with a home made fiberglass cowl.covered is oracover. Graphics are done on the computor using sign writing vinyl.
