Hey Everyone,

Here is a sneak peek at Guru Aviation's Lucky Yak We are still in test mode with it, but so far it is flying awesome!! More pics and info to follow as we get done with testing!!

Brother, it looks even better in the sunlight!

Guys, this one has some neat features, most notably, it requires no carbon fiber bracing! Instead it features the innovative "Lucky Brakes" that not only strengthen the bird, but offer drag brakes at the same time, to keep your down-line speeds constant.

After Lucky is satisfied with the results of the stress tests, we hope to get this one and the GURU jet up for sale on our webstore.

We still want to test with a couple of different motors, but hope to have this done over the weekend. More details to follow!

That is really nice Chris. As mentioned those are big ailerons. Great control. Wish I could paint like that :x

 

Way to go Chris, she looks awesome!!!

Thanks Guys,

They are some big aileron's, I like to roll ...Actually they are just right..like Tim said there are some unique speed brake/brace system on the plane, which you can not see in the pic, when testing is complete, I will show more pics. So far it is working, the plane slows way down and the down lines are slow..this was designed to be an indoor plane, and so far it has been awesome!!!!! More to come.....

Man that's a cool looking plane! How did you apply the skull, is it air brushed on?

 

Thanks!!! It was airbrushed...I did the skull first, then painted around it.. it came out really good.

Chris

 

Video coming very soon guys!!

ok here is the video of the first test flight of the Guru Aviation's Lucky Yak...
It was about 10mph winds, so the first little bit was trying to get it trimmed..but for a plane that was design for strickly indoors it handled it great..I drop a little secret...some already know...there is no carbon fiber on the plane More to come about the design and the new lucky brakes!
Hope yall like
Chris

 

Thanks Randy..it did fly very well in the wind I love knife edge Now that I have the rates in my transmitter the way I want, maybe next video will have some wing drag knife edges in it...Tim did tell me not kill it yet..lol!!! He is my ground control...but what he dont know wont hurt him..hehehe.. oh wait a minute he will see this..lol

hmmm spar...hmmmmm...close it has two functions actually. It work out really nice. Im waiting for Tim to fly his so I can get his feed back...before we show all. I want it to be right!!

Hey Mark,

You left out what John used!!! I tell ya the way I learned. I have close to 3000 hours on a simulator, which helped a lot. Thats where I would go to learn the stick inputs, then I would go fly the foamie in the yard.
I think the best way to learn the inputs, regardless if you use a sim or not is to practice the different knife edges. For example, do a left to right knife edge which is canopy facing you, you using right rudder. Roll it to belly facing you now you using left rudder. Keep doing that faster and faster before you know it you can slow it down. Cause the only time you are going to use the rudder inputs are when the plane is in the knife edge pos. Of course after learning that you will need to know when to add elevator to keep the height you want and to make it in a circle.
It is not as hard as people think, it is all about timing, and once you learn it you got it.
Hope that makes sense.

Chris

 

Nice looking plane guys, I have a soft spot for Yaks and yours seems to fly really nicely. I know how good you are on the sticks Lucky (i've seen the vids too ) but it doesn't seem like it has any bad habits. K/E coupling looked minimal and I didn't see much wing rock in HiA although it was difficult to tell because of the wind.

Mark, like Lucky says a simulator is a great learning tool (i'm guessing that's what John recommended too?). I dread to think how many hours i've put in on mine, but I remember spending 2 weeks solid learning to do rolling harriers.
If you want to learn to fly knife edge then i've got one tip for you..
When the top of the model is facing you then push the rudder stick towards the tail.
when the bottom of the model is facing you then push the rudder stick towards the nose.
This works whichever direction you roll into KE and whether you start from upright or inverted flight.

Si.

 

Thanks...

From what I have gotten so far...I dont see any bad habits at all..it didn't have any wing rock in a harrier..hovers easy..even in the wind it locked in very well!! There was minimal coupling in knife edge which is normal.. it was hard to tell what was wind or coupling. I hadn't had a calm day yet to fly it or somewhere indoors. But so far this thing Rocks!!!

Randy, Chris doesn't have a scale (yet!) he can weigh it on, But we are looking more at a weight range of 5-6 ounces. Mine came in at 5.6, so Lucky's should be pretty close to that.

Hopefully we can get some indoor video before to long for you guys. Chris is working on an indoor site closer to home for him, and I am hoping to get some down here as well...of course, I am not half the pilot Chris is, so mine won't be near as impressive!

Thanks Randy,

The goal was to hit 5 to 6oz. mark. I tell ya it flys like it is lighter than that. The first motor I tried on it was a little under powered, dont have the numbers Tim knows them, Right now It has an Axi 2204/54 on it..which is close to an 300 brushless motor.
The speed brake system I designed for it really works, but with drag it has it needed power to move it. But the other motor flew it fine I just couldn't push it to the limits I wanted, but for a first timer indoors it would be perfect, it just flew around nice and slow like a trainer.
I'm throwing everything at it to test it, this afternoon at the field it was calm and I got a flight on it, all I can say... can't wait to put it indoors...would have gotten video but I was testing my big yak out for a fly-in this weekend. I learned this after noon...don't do a snap on take off on the wrong rates or enough speed cause it will make your boxer shorts turn into tighty whiteys :x My wife says her chest still hurts, she normally won't watch cause she says I scare her....
The cool thing about the Guru Lucky Yak is it will be offered in two versions a yak or a 260 and maybe another one Tim is working on.
