RE: Extreme Flight 87" Yak 54 - Build & Fly
I know a bunch of you guys have been using the Smart Fly Fiber Optic kill switch..I have 2 of them on the way..When using this on the igniton, couldnt you eliminate the actual switch and just use the SF unit to turn the ignition on and off via your TX? You would need to unplug the packs at then end of the day cause they do draw some power even when off...I guess if you can, then the same would go for the RX?

RE: Extreme Flight 87" Yak 54 - Build & Fly
Wayne,
I have been flying the 42% Extra 260 for one year, and it is a dream come true!
I have been following this thread for months now, and I have 3 of these YAKs on order (2 for my friends). This one has been stuck at the dream stage though. I just hope it will come true some day.....

CF landing gear
Hi Guys,
I have a KMP 87" Yak and I talked with Mike at Graph Tech to see if they were going to make CF gear for our planes. He said yes, but he needed dimensions. I figured I'd gather up the dimensions for the various brands of 84-87" Yaks out there and send them all to him. They should be close enough in dimension that he can make one that will fit them all, which I'm sure is what he'd want to do. So, if you guys can help out and send me the dimensions of your gear, it would help. Multiple responses are fine, since it would be nice to get multiple examples to make sure we're getting it right.
Here's what he'll need:
He needs three dimensions. A, B, C, D. Here is a description of what they are:
“A†is the width of the gear across the fuselage, “B†is the height from the top of the gear to the center of the axle, “C†is the width of the gear at the axles, “D†is the width at the top of the gear from front to back - at the mounting point.
They don't have a measurement for angle of the gear, but I'm pretty sure that will be close for all of them and I'll provide that measurement, but if you can you can add that to, that would be great. If you were looking down on the gear it would be the dimension from the front of the top of the gear to the front for the bottom of the gear.
Thanks in advance.

The TNT website quotes the height of the gear at 10"...

Thanks Torqued-Up. I had found that, but they didn't say whether that was total height, or the height to the axle, so I need to verify.
BTW, from the dimensions Doug gave it looks like the EF gear may be very close to the KMP gear, but the TOC gear seems to be quite a bit different, which is a surprise to me. I expected it to be identical to at least the KMP gear.

Graphtech RC is suppose to have carbon fiber gear for the 87" EF Yak any day now. I am not sure of the price, but I know he is making them. I will post more information after I talk with him today. I am a dealer for Graphtech and will be getting some in stock as soon as they are ready. Email me if any of you want some at [email protected]

If you read my whole post you will see that I am working with Mike at Graph Tech to get all the dimensions so he can make the gear. He is not making the gear, but you're right, they will be available soon....after I get the dimensions to him that I've been requesting. I still need the balance of the dimensions from Doug for the EF(or you for that matter if you can get them to me), and the BME and QQ dimensions. Obviously, it is going to make the most sense for Graph Tech to make one set for all the 50cc Yaks if possible.

Sorry about that Bill!
The reason I did it on MS paint was to try and show the sweep in the legs.
Here you go >

Thanks Doug, that does it fine. Actually, you don't show any sweep in your first picture, but you do show the angle of the back of the leg. Sweep is actually where the front of the bottom of the gear is in front of the front of the top of the gear. The KMP has a 1" sweep forward, and the TOC has a 1.5" sweep.
Thanks again.

The front of the leg is stright and the rear of the leg has a taper cut which sweeps the axle foreward some.

I added a picture below, which I should have done like you in the first place, to show sweep.
Thanks again for all your help.

RE: Extreme Flight 87" Yak 54 - Build & Fly
Hey Bill
your absolutely right!
Just checked my gear on a flat table with a square, and your right as I get about the same one inch sweep to the front. Just looking at the gear, I thought the front was straight. Wrong.
Man!.....not easy getting the right info out of me
Sorry about that, but I think you have the right info now.

No problem Doug. It's not you. It sounds easy, but getting it right doesn't seem so easy. I should have made the drawings in the first place and there wouldn't have been any confusion.
Anyway, thanks, that helps.

One of the reasons they "require" this is because the smart-fly actually draws current, even with the rx turned off, and would slowy drain the battery when the plane's "in the hangar". I am running li-ions, and have to unplug my batteries after every day of flying, so that debunks that, and this is the main reason for them requiring the switch.
The other reason is safety. Well, if properly set-up (meaning, the receiver part is not subject to stray light, which could give it a false "on" signal), the ignition will not work without the radio system turned on. Also, assuming you needed to quiclky turn the engine off on the ground, the plane should be fairly secure, i.e held by another person or a plane holder, and should give you time to either cut the throttle back and pull the throttle trim all the way back to cutoff to kill the engine, or to simply turn the airplane power off. The ignition should then cutoff, by design. If it is a major catastrophe and your ignition control takes a complete dump and your setup is like mine, you can access the ignition battery connection and yank it to kill the engine. Mine has the quick-release hatch and my battery and plug are right there, in the open. If this one-in-a-million situation occured, I could yank that battery in under 10 seconds.

If any of you are interested in the Ipod nano, you might find this interesting. I did. Freeeeeeeeeeeeeee. hehe.
Godspeed and fly safely.

RE: Extreme Flight 87" Yak 54 - Build & Fly
HOW EASY? So Easy my 10 year old can fly it!!!! This plane is really great. He did the take off, flight and landing all by himself......
My son wants to compete next year in IMAC with the Red Bull in the basic class. He still has a lot to learn but it won't be long till I am asking him if I can fuel up his plane that I bought for him[>:] I am sure that I will be the best pit boy around......
I tried to get better pics but I was too nervous watching him fly....
