It usually happens in threes. Well I managed to kill 3 planes in one afternoon in various degrees.

For all NZ parkflyers we have launched a new site for you guys to hang out in. After a recent discussion it was a gap in the NZ market. It is totally free devoid of ads and sponsership so you are free to review any kit you have had honestly there.

Also if you know any newbie or someone interested in starting to fly in NZ we are there to help them.

Feel free to join and ask any questions you might have.

Just through I would post a quick vid of what I have been up to recently.

Thunderbird almost maiden (3 min 14 sec)

<Winter rant mode>

I have a growing fleet of planes and sadly enough most of them have not been built yet.

When I am not working the weather is bad so I can't fly and it depresses me so I don't build.. besides the garage is cold so try and avoid it.

Now I have a Formosa half built on the bench. A 2.6m DG1000 glider on the dining room table in a box waiting to be built mildly annoying the wife. A Flyfly Thunderbird EDF on its way with some new extreme blades for my Lama. The Thunderbird is so I can get used to EDF before I build the Illusion which is still under my workbench.

That does not include the SAAB Gripen that I have hanging from my roof which I have halfway built. Just contemplating the engine for it. Pusher prop or ducted fan.

So time to get off my #$$ and time to start building I think. However I am not on my way to work... bleh...

Roll on summer.

After my 2 year old saying buy it .... well how could I resist.

Got myself a Learn v4 to learn how fly a helli. However that being said took me a while to get the hovering right.

Only problem I have is a good place to fly. Lounge is nice but not so friendly for flying around in. Garage is full of stuff... Garden is fine but the wind blows and it does not like that to much. Already had to break a set of blades when I dropped it after my daughter decided to get to close. Value her more than the chopper.

Either way now I am looking at ways to give it more power for flying outside, trying to make it more wind resistant etc. So any ideas are welcome.

Took the wife and daughter to the local park to show my wife that I am not just blowing up the planes. ;-)

Wind started picking up however gave it a good hurl and she was away... My first hand launch by myself.

Flight was good flipped her around and had lots of fun.

Second handlanch was an almost crash. Did not launch on full power as she was pulling out my hand on full power. So she just did not have enough go... Managed to get my hand back to the throttle just in time as she skimmed the ground.

Again a really good flight. ;-)

Been a while since I last flew, seeing my last maiden was a massive fireball. Bad luck but enough to make me think can I really fly.

Friend of mine helped me by allowing me to plug my DX7 into his DX7 and take his plane for a flip. At that point I knew that it was just bad luck the last crash.

So I completed that Mustang... Waited the perfect weather, and yesterday was it. So we ventured to the local field and my word there were a lot of people flying. (Dang now I have to maiden in front of a crowd)

Good side the battery was still not totally charged so I let that charge while I watched the other planes and gliders fly.

Eventually the battery charged up. It was my turn.

Heart beating like a fast revving engine. My stomach in knots and I throttle up and my mate gives it a good toss.........

My heart stops but hey it is flying up up and away... Told myself no acrobatics on the maiden just get used to it again... <Evil me pops in and sneaks in a loop or two>

Brought her in for a smooth landing. Let the heart return to normal etc.

Had a bit of water and relax... Then off for the second flight, much more relaxed and enjoyable.

I am back and can't wait for my Formosa to arrive now.

Well after my Big Nasty decided to go up in flames I have been slowly getting the parts to build another plane.

I still need to get a new speed controller for a brushless and a lipo and maybe a new brushless motor depending if the other one was cooked in the fireball.

However I decided I was am going to buy instead of build my next plane. Decided on a GWS Formasa which I will most probally wrap with something.

However it will be a brushless setup.

I my garage however I now have sitting some bits and bobs, which I am debating on how to build them into a temp flyer.

This is what I have...

1 x 7 Cell NiMH battery pack.
1 x speed controller and 1 x GWS EDF 75.
(see where I am going here)
1 x Spektrum Nano pack with 4 nano servers. (Man they are small)
Some EEP offcuts enough to make a basic fusalage I think.
some 2mm Depron... enough to make a wing or so.
some 6 mm Depron and I think I have some 3mm depron there as well. But not much..

Any ideas on what type of EDF trainer I could build out of this?

This guy really knows how to make this jet fly gracefully.

Will get there someday...

Thanks Darth Elevator for that comment.

Didn't scroll down Duh....

Trying to figure this one out... Must be missing something somewhere.

On to the path of recovery... New Spektrum receiver and 4 new servos have been ordered. There goes the budget. ;-)

Ok now that I have had a beer and a nights rest I have managed to figure out what caused my plane to go bang.

I have learnt something in my building of planes now because of this. Hopefully this will stop someone else making the same mistake.

For the first flight we moved the battery forward to give it a bit more nose down feel just until we get the hang of the big nasty. (There is the start of the problem) On my motor I have a shaft that runs out the back of the motor by a few cm. (The more clever of you might be seeing what happened already)

Looking at the wing I noticed that the left ones corner was slightly folded which indicates she tipped a wing into the ground as she touched. Looking at the motor mount and the way the wood snapped indicated that the engine bay took a knock in the same way.

This then in turn pushed the motors shaft back through and into 2 of the 3 cells. We all know that when a Lipo is punctured it goes bang quite nicely.

Moral of the story...

If you have any sharp objects in the area of the battery even a few centimeters away put some protection between the battery and sharp object. If I had put a bit of plywood just behind the motor it would most probably not have hit the battery at all.

The most depressing thing about it all is that if the battery had not gone bang it would have been about 30min repair work at most. Basically making a new engine mount. Wing would not even have had to been repaired.

Well I need a place to vent a bit. So I thought a blog would be a good place to start.

After many hours flying a friend of mines trainer and being successful in doing all the stunts that a trainer could do I decided to move up to a "Big Nasty"

All credits to the big nasty the design is brilliant. However I built it a little differently. Fuselage out of EPP and wings depron no undercarriage even through all those small mods the center of COG was spot on.

After much encouragement from my friend and many hours doing simulator flying simulating all failures such as engine failure recovering from stalls etc I felt I had the courage to take build and take the Big Nasty for her first flight.

Hand launched fine, and she went up up and over our heads... not a problem seems to have to much up elevator must trim it down. So right her bring her round but now she is going behind some trees. So to be on the safe side I know the field on the other side is empty kill the power and level her out for a unguided landing into the soft grass.

Take a quick run round the trees expecting to see a broken prop or at worst a wing that needs to be rebuilt to see smoke coming from the field.

She must have bumped the battery in the landing and it exploded into a fireball. All that was left was the tail section and the two wingtips indicating the landed fairly well for a unguided attempt.

Out of this I might be able to salvage the motor. However the battery pack (bugger)...Continue Reading
