I love flying in the wind.

Don't get me wrong, I prefer to fly in no wind. In good conditions I can fly precise and smooth and so great stuff.

But when it is windy you can practice a lot of other techniques that are also fun. Playing with the wind and T Roll sliding down wind, reverse harriers, back up snakes, extreme waterfalls can be a lot of fun. Also, learning how to take out the burbles and smooth out a flight in turbulence is a great skill.

Lets face it, it is windy at least 50% of the time. Learning how to fly, "and have fun", during that other 50% is huge!

Crack Yak vrs Crack Yak Lite AUW

Have set up both the Crack Yak and the Crack Yak Lite with the identical 'lite gear setup'.
Results:
1) Finished build weight:
Crack Yak - 132 grams or 4.6 oz
Crack Yak Lite - 122 grams or 4.3 oz
RTF weight: add 17 grams or .6 oz to above weights (Nano Tech 2S 300mah battery)
2) Set up:
Motor: Dualsky 1620kv - 20 grams with built in ESC
Servos: D47 or equiv.
Rx: 3 gram
Battery: Nano Tech 300mah 2S (35-70C). 4.5 minutes of mixed flying uses 170 mah, thus leave plenty of reserve battery.
3) Flight results:
Very satisfactory in all respects. Extremely low wing loading provides for soft flight characteristics while still maintaining the precise control response that the Yak has become so respected.
I believe that anyone whom truly enjoys the concept of building lite, and the resulting pleasant flight characteristics, will not be disappointed. Both these fine machines respond very well to the 'lite gear' set up.

My CY probably has an extra half ounce of welders in it. I was worried about all the repairs building up over the months but I actually think I like it better with a little weight, vertical suffers of course, but I think it helps keep some momentum, which I like, makes it feel a little more like a bigger plane.

At my field, the guys all seem to like watching me fly the CY over my other 3D Planes, the Crack Yak is BOSS.

How does flying the CY in RF 6.5 compare to real life?

Its actually a really close representation of how it really flies. The CY in RF is a little too twitchy when hovering though. Its much easier in real life.

Excellent example of what can be done with some thought and effort. Well done. You have crossed the threshold and exceeded published specifications by a wide margin. Building heavy does not require much thought, building light to this degree requires thought and finesse....well done....enjoy flying lite.

Any chance somebody will model the CP in RF?

Nice work! Do you notice a big difference between the Lite and Standard being that the weight is now so close? I bet they still fly very different.

I believe I might best answer this by suggesting that the difference or, similarities, would depend significantly on flight style of the operator. You are correct in that they still have their unique flight characteristics, however with the added pleasure of extremely light wing loading. As always, both great machines......Cheers...D
