HK401B GYRO on Atom 500

Very good tail control and hold in very strong wind. Tested this gyro on Atom. Couldn't see much different from GY401. So why pay more for the same holding power. :-).

PC-9 EP build

Project completed.










I cannot take it to see my PC-9 left cold so I start building her. It takes good 2 hours to install servo and landing gear.


Completed with the first part of assembly (landing gear and servos)


Aileron control. Only left with covering the servo's wire

Nose landing gear

elevator and rudder


servo bay

Tomorrow night with motor and ESC....stay tuned..

Maiden flight

.

UH1 Mini Titan

UH1 Mini Titan from Thunder Tiger. Nice detail and comes with all you need to fix your mini titan with this fuse.

PC9 EP

I always admire PC7 but the most important thing is I want EP not GP. But the closest I can get is PC9. So I today I went to yapan and I saw this PC9 hanging in his shop. This is just a sneak peak preview of PC9 EP made in Thailand.

Dragonus vision canopy

New canopy in action









I don't like the new vision canopy so I did some modification to the canopy. This is my modification to it. My paint job ain't great..it's crude but heck I just wanted a clear to see color. I think I like this design better then the original one that suppose to look like this.

Reviving my dragonus

Dragonus is my first training heli which really help me a lot to learn and progress up to my current level. But after I started to invest in new heli because of the vibration problem of my dragonus for the past several years. I had to retired all my dragonus and fixed them with fuselage. But later then after I've sold my current 3d training heli 450v2 to my friend I've decided to bring my dragonus back. And the feeling was awesome. I can do my 3D the way I like it. I can start my idle up and go straigth to inverted from the ground. The stability makes me fall in love back with my dragonus.

Here is some of the picture of my dragonus with new canopy I took from my 450v2. I like this canopy better than dragonus original canopy since it much harder and crash resistance. It can protect my lipo incase of crashes. Although I had to do some mod to the canopy support to move it to the front.

Corona CT8F V2 DSSS for futaba

My first experience with corona 2.4Ghz system. I bought this set second hand from my good fellow kelfo from mrc together with Futaba 9chp..really good deal. I believed this is the model spec. This system uses DSSS technology.

Spec.
Size: 37mm*59mm*22mm
Voltage : 4.8 V - 6V
Range : more than 1500m
Operating current : 30 MA
Sensitivity : 100dbm
Latency : 22ms

Included.
Futaba 2.4Ghz Module
Antenna
2.4Ghz Receiver

1. Fit nicely on the back of FF9 module slot. No wobble or moving part. Feel secure. Antenna design look like Assan module. The case design was not so presentable. Not as nice as Assan design.

2. The receiver is 8 Channel 2.4Ghz DSSS Receiver. The price is not bad aground usd22.

Spec.

Size : 46mm*25mm*16mm
Voltage : 4.8 V - 6V
range : more than 2100m
Operating current : 30 MA
Sensitivity : -100dbm
Latency : 22ms



I put this rx on 450v2 and fit nicely under the heli compartment. More than enough channel (8ch!!).



Binding takes bring me a little puzzle. Takes me a while to understand the binding procedure. Where you need press button under the rx belly and power on the rx. Then press the button behind the tx module then power up the tx. Then Wait for the binding confirmation. Then it's done.

3. First flight. Before that on the "switching on" procedure you have to switch on your tx first and leave it for around 10 seconds then power up your rx. The boot-up latency is quite high compared to Assan where you don't have to wait for that long. If you switch on your rx before the module initialize then your esc will stuck indefinitely and you need to cycle it back. Before this I though I have to switch on my esc first then my tx since it really worked that way. But then I've realized that I power up my esc quite fast before the tx done it's initialization.

During the flight test this morning I did noticed the servo jitter a bit but for a split second (or maybe my imagination). 2-3 times before take off. But after than everything was OK.

Good point
1. Cheap as dirt
2. Range??? the rx labeled as full range...never tested this claimed.
3. hmmm

Bad point
1. Unattractive module and rx case design
2. Binding a bit weird and confusing
3. Servo Jitter???
4. Boot up latency quite high
5. Powering up is quite strange since it need to switch on the esc first then the radio. Strange right?

Conclusion
Although the kit price is very cheap but I would prefer Assan system over corona. But this just my own view. Also the rx price range is almost the same.
