It's Gona Be HOT !

We are talking Bush Fire Hot !
Tire Melting Hot !
My radiator just blew up HOT !

Yes , the next few days are going to be smouldering !
Going back a few days I re-visited my V911 Wing ..
In a Nutshell it bites ..
Just a rubbish design ( DIY ) ..

That means I have a spare V911 board to play with
So with some seriously , seriously warm weather on the way .
I started a 480mm V911 glider .

I figure since I will be trapped behind Air conditioning for a few days , I have some time to kill . Eeeer or maybe time to build another glider !
So I got myself a bit of a head start ...
Got the hollowing out done , as it needed to be done outside over the rubbish bin ..
Everything else can be done inside ...

Raven @ the Park !

A) I didn't break the raven , even with a few too fast landings
B) With the larger battery the CG is a little further forward and the elevator is really nice ( Did I move it about 5mm forward )
C) I did need to completely re-tune the Raven , it is almost hands off now ..
D) Lucky for me , the glide tune works a treat on launch ( No launch setting needed )
E) The Raven does like to glide with a bit of speed , not overly liking the slow speed stuff
F) I did try tuning in some flap for a slower glide , but definitely will need some down elevator mixing , otherwise the nose lifts and the Raven stalls out .
G) I need to change switches for the flap , I picked a bad switch .. Not intuitive to get to .

Did I mention , I didn't break the Raven ...
Seems all that extra cyno is helping .. ( From the previous repairs )

Prime Jet pro
It's done , it's ready ...
I need to do a CG test to see if it glides or GLUDS ! ( Glud being thumping the ground )
The 800mAh 2s battery is literally as far forward as I can get it to match the back yard glide tests . ( FF )

It has been super humid for weeks ...
Today was relatively less humid ...

How far are we from the Equator ?

Got the 4ch FS2A Rx soldered up .. ( Pins to board )
Next I will bind the Rx to the Qx7 .. And then put it in the PJp ... And Program Elevons .

Getting there !

A quick recap ! sent me a 50mm EDF for review testing ..
To really test it , it should go into a plane ..
The plane is the Prime Jet pro from HobbyKing , and be one of those foam board cut out's ...
It took a long time for the EDF to get here , so the model did nothing for a while ..

Obviously for a EDF to replace a pusher prop , a little tweaking is required ..
Fuselage was shortened , and a cut out made for the EDF ..
Vertical stabilisers were moved inboard to stiffen the area around the EDF ..

Since then ...
The larger carbon spar was installed , epoxied each end .
When the epoxy dried I ran a bead of white glue along the spar for contact with the wing ( more stiffness )
Also I added some runners underneath to which I attached a skid plate for the EDF .. ( Keep it out of the dirt )
Also I used some budget 9g servos I got (?) a long time ago for projects ( Just like this ) ..

Needs doing ...
Solder the connecting pins to a 4ch Rx ( FS2A )
Bind the Rx and locate the 2s battery ...

Ooooh yeah !
After installing the EDF , I gave it a run on the intended 2s battery
Looks like 2s will power this project just fine ...

That elusive G Spot !
Where Oh where will the Centre Of Gravity go ?
Anyone watch the Chucky Video ?

I havent put in any RC gear ..
But I thought I might Chuck it some more ...
It does seem to like / favour a forward CG , perhaps it's that Canard ? Lifting the nose ?

Prime Jet pro Back Yard Chuck's (4 min 22 sec)

Next I will start installing the RC goodies , I will start with the 9g servos , then solder up a 4ch FS2A Rx and then install the ESC and EDF .

Hmmmm , I might Park it before I try to apply power ( The little hill = test glide )

HK Prime Jet pro - project is moving forwards ..
A little more work and the foam bits will be glued ..
It did require some thought , as one needed to re-design it for a EDF ..

Also the wing for Ripit Rev 2.? or Rev3 ( Havent decided yet )
But the wing is moving along ..
Depron and foam glued together ( laminate ) ..

Windy and warm / hot .. A whole week of it !

I do sincerely apologise if I gush a little , the Ganzo FireBird is simply the best Chinese made knife I have experienced to date . The firebird takes Chinese made knives to the next level and priced around $25 USD , one is simply getting a lot of knife for the money . The knife is tight , there is no slop anywhere . The carbon fibre handle feels solid and perhaps a little cold and mechanical . I thought the clip might bite my palm , but no ! Carving up a cardboard box I could barely feel the clip . Also the blade size / thickness is just right , cutting through the cardboard with little resistance . Speaking of cutting ! When I had completed the task of turning the box into strips , I tried to shave my arm . Surprise surprise , it shaved hair with no trouble at all ! Seriously ? , most other knives get quite a bit of wear on the edge and can't shave hair after carving up cardboard . I am amazed that the firebird held it's edge so well . Quite frankly this just might be one of the best Chinese made knives out there , certainly the best that has passed through my hands . I have to say , if you collect or like cheap knives . Then you really need to pony up a little more and get the firebird from Ganzo . Here is a knife that can compete with the more expensive brand name knives from Europe and the USA . If Ganzo continues to make knives like the firebird for the lower end of the $$ market , I would say...Continue Reading

I came home after my morning walk and there was a box waiting for me .

Inside was a 50mm FMS EDF ..
The bullet connectors were pre soldered so all I needed to do to run some current measurements was connect a ESC .

2s = The EDF pulled 11.5 amp from a 2200 2s battery pack

3s = The EDF pulled 19.5 amp from a 2200 3s battery pack

Now I have to say that the motor did run smooth out of the box .
On the 2s there was some useful thrust , how much ?
How ever on the 3s it was just crazy .. At full power the thrust is just simply impressive as is the noise this EDF makes .. ( Be loud )
This 50mm will go into a HK Prime Jet pro , and I will try both 2s and 3s batteries ..
3s will definitely power the Prime , and I think that 2s will do just fine ( I think ) , just have to see how heavy the prime turns out ..

Now if you read the speel on this motor , it is supposed to be 3s - 4s ....
On 4s this EDF would be insane , and I am not sure you would want to go there (?) .. That 4500kv motor is already howling on 3s ...
So from here on the FMS 50mm 4500kv EDF is partnering with the Prime Jet pro ...
This be only the first post on this project ..

Thank you , hopefully we will have some flying video's to view not to far into the future .

It's not hot , there was even a cool breeze ..
But with 70% humidity I was soaking wet when I got home !
I went straight into the shower to wash the salt encrustation of my body ...

How the hell can you have a cool breeze and be sweating buckets ?
Come to Melbourne and find out ...

Aaaah yes , the TechOne DLG 1000

A) I pulled the last remaining lead out ( how the ? , did the previous owner ? , ??? )
B) I did quite a bit of peg launching and the DLG 1000 wants a little right rudder on launch to keep it straight . Otherwise it tends to want to roll left / launching off the left wing .
C) I even moved the battery further back to nudge the CG back .. Now the elevator is a little more sensitive and I put in 20% expo which was amended to 15% expo .
D) Flying weight is right on about 199 grams
E) The DLG 1000 is really twitchy on the roll axis for some reason , drop flaps and the situation improves . ( Flies real nice with flaps down )
F) I did mix in one of the rotary pots to adjust the angle of the Ailerons ( Mild flap ) ? So far
G) It glides ok now , but really cant hold onto that altitude .. It drops out of the sky relatively fast . ( Why Im playing with Flaperon angles )
H) I think I understand now why so many SLOPE the DLG 1000 , possibly more of a slope model than a true DLG ..

One hour spent sweating at the park .. The battery was off the charger at 8.4v and when put back on the charger was about 8v ..
Thats not bad for...Continue Reading

Parking FF Fun (12 min 40 sec)

Parking FF Fun ....

I was at the park , free flighting , and having fun ...
So I took all 3 of my small powered FF models to the park .
It really was too windy for them .
I started off throwing them into the wind , which was some what of a wast of time ...
The trick was to simply throw them down wind .

Tuning was difficult with so much wind .. But I did get in some long walks to retrieve the models after the battery in the action cam gave out ..
Got to remember to recharge the battery . These action cams really do suffer from parasitic drain something terrible .

Which one was best ?
Well , I don't know that the word best applies in this case .
I do like the lipo glider as it gives you a 15 second engine run and you don't need any batteries to recharge a capacitor .. Just push the button and go .
The capacitor gliders are lighter , and when tuned seem to glide reasonably and slightly better than the lipo glider ..

Again the conditions were windy , so no glider was in it's element and too much POT luck was involved .
Not one of the gliders wanted to be launched into the wind . The wind would just take the glider and do it's own thing , most of the time resulting in the glider just smacking terrafirma ...

Launching downwind certainly improved the odds of a decent flight , but there was not much gliding in evidence due to the wind .. Once the power dropped off on the motors the wind took over...Continue Reading

I was on FeeBay and spied this Lipo powered FF Glider .
Be very similar to the capacitor FF gliders , well (?) - Only it's not !

A) This particular glider is much more sturdy , not flimsy like some of the Capacitor Gliders out there
B) It's powered by a lipo battery , so you don't need to carry batteries about with you
C) Some what easy to tune for a decent flight

The lipo battery makes this one very interesting .
The motor does a pretty much full power run for 15 seconds and then cuts off .
So the battery should last for quite some time .
Just push down the button on top the canopy for a 15 second burst of power ( simple ) ..
And to recharge the battery , just connect to a USB power source .. Probably want a low current source for such a small battery .
To date , this one would have to be the most impressive Powered FF Glider I have ( to date .. )
Starting around $10 Ozzi bananas , it's probably a very affordable way to get anyone out and about flying a model .
I have bounced mine of the brick wall a few times now tuning the glide with no damage , so I would suggest it is rather durable .

I would definitely rate this one = Cheap Fun !
Oh! And let's not forget the potential of the internal goodies , for use in possibly other models .

RIP V911 micro heli ( last flight ) (1 min 45 sec)

I don't remember how long I have had the V911 ?
But it was rather horrible on the factory Tx .
It was not till I bound it to my 9x that I got some real fun out of it .

But that was several years ago ..
And I do like the V911 boards for stuffing in other models ..
Since there seems to be no more V911 control boards available (?) , my V911 micro heli is having it's heart ripped out and transplanted .
Not sure where yet , but I have some stuff on order for 2019 that might benefit from the V911 heart .

I hope everyone is setting up there Ducks for 2019 ?

Where are we ?

RIP Rev 2.3
I lowered the wing closer to the carbon boom and still very little rudder ..

RIP Rev 2.4
I increased the rudder 100% ( See picture ) , it is huge ! Simply dwarfs the Ripit .
And still little rudder ..


Something is FUBAR ! , I can only guess it is the wing for some reason .
This much rudder and no rudder ? , na na na ! Obviously something is NQR on the Rip Rev2
So I have put the rudder and wing in the rubbish bin along with the horribly bad centring servo ..
I am keeping the elevator / boom / pod assembly and will come back with a new servo / wing / rudder ...

I just might go with Ailerons next time around ( Rip Revision 3 )

Will be doing some tests on the Frsky Rx from Banggood .
Hopefully some interesting tests .
Techone DLG 1000 - Found a used one to buy
Real DLG Drought here in Oz !

Banggood = More DLG's ... ( Please )
Would love to see WLtoys do a Micro DLG around 700mm ( 2 or 3 channel )

Speaking off !

Found my V911 heli , I will pull out the control board and put it into a glider ..
In fact , I might keep the factory Tx to fly the glider with ( Just for a lark )
The other V911 board ? , one servo is damaged ..
I have another V911 board , but it resides in a micro Wing ..

I got some 949 boards , so they will go somewhere ..

????????? A few things to kick off 2019 ..

Picture of Servo included ...

Dont know what to say - Just not impressed !


A) Rudder throw doubled ( Need that rudder )
B) Dihedral increased

I will re-attach the wing today ..
Way too hot to Park it ! ( 36c or 97f predicted for today ) Would not be surprised if it tops 100f though

Ripit Rev2 (0 min 44 sec)

Ripit Rev2 is ready ....

Flying weight wet = 49.3 grams
I did try to go light , I really did .
The depron must simply be heavy .

The small HK servos , not happy with them .
I do like the receiver though . ( FS2A )
Watch the video , I do some Free flight in the back yard ..

The wind is up a bit , but this morning when I was looking for the CG there was no wind and the R/R2 glided like it was on rails .
I will have to go do some chuck testing ..
The weight is very close to the Ripit 1 ( 50 grams ) , and the RR2 is 49.3 grams ..
I must - I must try balsa ...
Next one ..

Update :

Went to the park

A) Those hobbyking servos bite the big one , horrendously poor centring ( Will provide a picture shortly - they be bad )
B) No rudder = ?? - Yep , physically it's there but the effect is zero
C) Elevator , effective . Perhaps a little sensitive .
D) Need more dihedral
