I have retrieved another abandoned balsa build from around 5 years ago.
This HobbyKing Sunbirds only crime  was to have the wrong trailing edge stock.
I managed to find some suitable stuff in my balsa box and now it is ready for it`s maiden flight.
The weather has been pretty unfriendly  so we will see how she flies when the sun can be bothered to put his hat on and come out to play again.

That looks like it should be really sleek and fast

Very nice...got a chance to watch a Kunai fly this weekend...newer sleeker version...powered gliders with aileron's are very fun.

Hi Jeff,
I`m pretty sure you`re right , it has a nice thin airfoil and from what I`ve seen on Youtube most pilots are pretty pleased with the performance.
It has a 1.5 meter span and weighs around 500 grams, which is about 400 grams lighter than the Phoenix 1600.
I bought this kit for around £ 27.00 from HK but they have discontinued it.

It must be a good model as it sold out in most UK stores🙂
Looking at the specs it makes this Sunbird look somewhat prehistoric.
Trying to fly a Sunbird like the Kunai would just end in broken wings, but it does look sleek compared to the DB Rookie🙂

I was really lucky today as I manged to get a good window in the weather to maiden the HK Sunbird.
Just as I got home it began to pour with rain.
All up weight for my Sunbird build is 530 grams. It has a 2208  motor swing a 10x6 prop, but I can`t remember the exact kva between 1000 and 1300 I think. It is powered by a 1000mHa zippy compact LiPo and I have had excellent service from these little batteries.
Some issues need addressing, like cooling for the motor, ESC braking and a dodgy aileron.
I will probably get rid of the bulky rubber bands and screw fit the wing to fuselage.
When these problems are sorted I am expecting some good flight times with this little soarer.
I would definitely say i`st not for the beginner as once it starts to drop a wing you need to be on your toes to prevent a nasty tip stall.
The field was very wet due to the amount of rain we have had recently, but there was a bit of lift and lots of sink as well.
I am very pleased with the results and wish I had got this finished sooner.

Nice job. 🙂 15 minutes out of a 1000 battery that's pretty good, once you get the brake working you should really be able to glide around a lot longer.

Thanks Jeff,
Not too shabby for a maiden flight 🙂 39% left in the battery after the 15 minute flight🙂
If I were to change something on this plane it would be to have a slightly larger H stab and less of a taper on the outer wing panel.
Proposed legislation for RC model flying in the UK is draconian and I am on a mission to get as many attic exiles down and flown before they are put into place. It looks like I will be going back to free flight and sub 250 gram planes.

I think this is awesome of you getting out all the old builds and getting them going. It's like starting your childhood over 🙂 .

It is, but I never had planes when I was a kid apart from the Graupner Uhu my Aunts sent me from Germany when I was about 7.
We lost that glider in an oak tree after a couple of seconds. That gave me the love of flying but it was`nt until my 20`s that I could afford to buy and build.
When I fix up these old builds I do feel some of the excitement I felt all those years ago along with some happy memories. 
I had lost interest building with depron and these attic retrieves have boosted my enthusiasm for flying again.

Thanks, I didn't notice that you had posted the complete specs.

Very light considering she has a motor.

My 1,6 m ws Windrider Fox weights 430 g, but is a pure glider that I built without rudder.

Don't regret the added weight of the HK covering, she may fly better than at a lighter weight as soon as the air is not perfectly still.

With the same CG, I can put a 2200 or a 1500 in my Easyglider, and she flies more often than not with the heavier battery, that allows me to fly faster away of sink zones, and the glider is much more stable in turbulent conditions.

For the batteries of my Easyglider I try to land with 3,8 V left, this way they are at their storage voltage after landing, and can wait to be charged the day before I'll use them again.

For the pure gliders that have lipos, I just charge them at storage voltage to fly (more than enough for 90 mn flights).

Cheers.

No need to apologize, the title is pretty obscure🙂

Thanks Q. I am really looking forward to some settled weather to fly it again, it is so changeable, rain one minute and sun the next.
I suppose it is the same where you are.
