X525 V3 ARF from Goodluckbuy

Category : Electronics, RC

I just took the next step and ordered a real quadcopter, it is a ARF kit thats based on the x525 frame. The contents of the kit looks okay, and I guess for a first time build it’s just a good thing most parts already has been selected for me.

Kit Contents:

– X525 V3 folding frame*1
– KKMulticopter v5.5 *1
– XXD 2212 KV1000 brushless motor*4
– 3.17mm Shaft adapter*4
– GEMFAN Carbon Nylon 90×50″ 9050 9050R CW CCW Propeller *4
– Hobbywing 20A ESC*4
– ESC Connect Board*1
– Heat shink tube*12
– Not assembled,just a kit

I will most likely not be using the KKMulticopter 5.5 board, instead I have a KK2 from Hobbyking on it’s way. It looks much easier for a newbie to understand and setup. As some extras to the kit I also got a few extra props, one screw set, prop savers. I also ordered one extra frame kit!

The receiver I’m gonna use is the Turnigy 9x, and for powering this quad I will be using the lipos listed under here. Of course I will not use both at the same time, but I thought I’d give it a shot with different C ratings and mAh:

I’ll try to update this blog with a build log.

 

WL-Toys V911 First Impressions

Category : RC

I got my v911 RTF package yesterday and here is my quick review & first impressions, lets do the technical first.

Heres a video of me practicing with my v911:

RTF Package contains:

  • 1x v911
  • 2x LiPo
  • 1x Charger
  • 1x Tailrotor
  • 1x Mainrotor set
  • 1x Transmitter
  • 1x Manual

This helicopter is a clone of the Align T-Rex 100, a very good one in my opinion and many others. My previous experience with rc helicopters are a few 4ch coaxes and one 4ch fixed pitch. I’ve never flown such a small 4ch fixed pitch helicopter before, the closest in size is the 4ch coax walkera 5#6. And if you ever flown a coax helicopter you’ll get the hand of the v911 very fast!

I got it flying and hovering beautifully at second liftoff, first try went into getting used to the transmitter. It blew me away how stable and well it flies, compared to my honey bee fp2 the tail motor and gyro is in another league. The v911 never misses the tail and keeps it stable 99% of the time. I’m truly shocked at how amazing this little thing is! I’ve had a few crashes

It also handles outdoor flying much more than any of my coaxes. I would really recommend this helicopter, for the price you can’t go wrong!

Pros:

– Price & Quality
– Easy to fly & hover (Easy as a coax)
– Durable!
– Speed (compared to a coax)
– Handles wind better than a coax

Cons:

– Battery insert can be tricky
– Annoying sounds from TX

 

RC Season 2012 – New Toys!

Category : RC

It’s been some time since my last blog about rc helicopters, so it’s time for a new. There haven’t been any changes for about 2-3 years, still got my Lama v3, Honey Bee FP2 & Walkera 5#6. Only one of them are in working condition, only the 5#6 can fly. My lama has a broken TX, and my FP2 misses some crystals(where did they go?).

So, I went back to RCGroups to check out the news on the rc front. And to my suprize quadcopters had really dropped in price! Walkera has some new neat models, the ladybug for example. They still cost, but not as much as those custom built ones. Of course you get what you pay for to some extent.

But I found a thread on the forums discussing about a new brand named WLToys, and their Blade MQx clone the V929. It has recieved very positive response, and many good reviews. Presumably it’s very easy to fly, flies well and stable it can also take a beat. The main argument for getting it is the price which is around 40-50$!

The V929 is my entry into the quadcopter universe, I just ordered one from eBay 47$ including shipping!

Now for some tech specs.

WL Toys V929

Main Wing Diameter: 13.5cm

More about this model later!
