Hey guys,
Check out Joe Hunts latest review on our 100cc Yak 54 QB!

Bobby Folsom

Mark, I flew my AQ QB 100cc Yak yesterday. It flew absolutely great!! It weights 29 lbs but you'd never know it. It has unlimited verticle doesn't bounce around in the wind, snaps so slow I'm going to have to learn how to do snaps all over, drops the nose just great in a stall and stops rotating in the spin when I let go of the sticks!!

I have a DA 100, MTW 75K canisters and a Biela 3-blade 26 x 10 prop on/in it, 5955s everywhere but throttle which has a 5985 ( won one at the Sherman, TX IMAC contest last fall that Hitec had donate prizes for). Using trottle management I can get it to fly the same speed upline and downline - it seems like I have to add power to get it to come down!!

The CG is at 3 3/4" and is just perfect. The recommended low rates on everything are probably okay if using a 28 x 10 Mejzlik but with the 3-blade Biela they are just a little slow so I used mid rates (which is 1/2 way between recommended high rate and low rate) on all three control surfaces

the electonics are: SmartFly power expander/super regulator, SmartFly pin switches (all with heavy duty wre and Deans connectors), Fromeco 4800 Peerless Li-ions on the flight pack and a 2400 on ignition with a Fromeco regulator and Electro Dynamics optical ignition cutoff switch. The RX is a JR synthesized receiver with the sysnthesized module plugged on a JR 10X.

All in all, Aeroworks has done another fine job. I told Rocco that if he built a plane with "bolt in canisters" that I would buy it - it did and the best part is that, hard to believe, flys better than the Extra 260!!


Thanks Rocco, Mark and the rest of the Aeroworks gang.

Bobby,
Glad to hear you like it! Ive been flying mine for about 3 weeks now and absolutly love it! Have fun with yours and let us know what you think when you get more time on it. My guess is you'll like it more than you do now!

Bobby Folsom

Here are several pictures of my Yak and equipment setup. The field is located in Mt. Pleasant, TX and is a great place to fly a first flight!! BTW, I went ahead and installed four 3/32" baffles behind the cut out wedge-shaped slots just in case. I added a 3/4 oz and epoxy finishing resin to them so that the oil/gas won't soften the wood. Didn't have a heating problem a tall.

Enjoy.

Bobby,

I really like the way you did your baffles. They should work out very well. Thanks for the idea. I'm going to borrow it and use in on another project.

Bobby Folsom

You're very welcome Silver. I'm glad to help out. This project is my first with canisters - I love the way they sound. BTW, Tom posted some pictures on canister installation the other day and I realized that I had installed the silicon tubes incorrectly. I was lucky that they hadn't fallen out!!

We are 3 guys here in the Oslo area (Norway) who has this plane. We have only gotten a few flights on them, but so far it really looks promising.

I also have the 100cc Yak, DA100 with stock mufflers, carbon gear, tail and tubes, Li-ons, Hitecs and Spektrum. Came in at 27lbs 1 oz. I noticed the three blade props. Im using a Mezlik 27-10 now. How much difference does the three bladers work and which size are you using? I am not a IMAC guy, just a fun flyer that does sport and 3D.

stick with the 2 blade for most types of flying. The 3 blades are nice for keeping the noise down, they accelerate smoother, and can sometimes help a bit with downline breaking. And, of course, they give you more ground clearance. Typically, though, 100cc planes used for freestyle/3D flying have a 2 blade. two blades accelerate the plane faster and typically have a little more grunt to the way they pull.

Lormuhl

Thanks for the info Bodyworks. Im happy with the plane the way it flys now, but always looking for improvements. I ll stay with the carbon 27-10 Mez.

Is it necessary to use the clear iron-on mat'l on the leading edge of the main wing panels? as per plans

larshkj

Who knows if it is necessary... ?
But I wouldn't be the one finding out it actually is! So my advise is to apply it. It's not a time-consuming process, and the clear strips of covering are supplied in the box.

Where do your graphics generally start to peel.... along the leading edge. That's what the clear is there to protect. Sure, the plane will fly without it, but next year, it will look better with it.

Hey Bobby, I'm in the process of putting together a 100cc QB yak. In the instructions in says to set up the ball links in different holes on the aileron control horns on the same wing panel, did you do this? just wondering about the ratio difference.

Thanks
Frank

Bobby Folsom

Yes, I did the aileron ball links exactly as the instructions state. I think it has to do with the varying aileron taper and total swing.travel volume. But since I used 5955s and programmed them with the programmer, I don't have any issues with the servos fighting each other.

Hey Bobby, do you recommend the baffles? also I'm using an older 3W 100 and I didn't need to use any spacers and I'm right at 71/2 inches, I thought I would need spacers, are 3W's usually this long?
Thanks

Hey Bobby, have you had any issues with the gear plates ripping out? This is what I've been reading

Bobby Folsom

Definitely put in the baffles and yes the 3W is a bit longer in the nose than a DA. The gear plate can't take much side load. I taxied into hale (only moving about 1 mph) the wheel dropped into the hole and rip - the gear plate pulled out. Others on the AW support list and Fling Cirkus have also mentioned avoiding side loads. Bottom line is LAND WELL!! Ha, that's easy to say but sometimes hard to do.

LOL Thanks for the info Bobby

I should also mention that the clear covering material has come off of both wings!! The first side to come off really threw us for a loop becasue we thought is was flutter and could not for the life of us figure out what was fluttering. I walked back to my trailer and some of the guys stood the Yak up on it's nose to get a better view and low and behold, there it was!! The clear covering was only attached at each end - the fluttering sound came from the stuff vibrating like a rubber band in the wind. Well, off it came and VIOLA - no more "flutter"!!

Two weekends ago at an IMAC contest in Yukon, OK the same thing happened on the other wing! I knew what it was this time and RIP - off the clear material came - no more problem. I had ironed down the covering very well so there is no danger of it coming loose!!

Take care.

Hey Bobby Folsom, can you tell me how and where you balanced your Yak? I know it says 3.5 inches back at the tip, crumby way to balance. Did you balance at the root and where?

Thanks
frank

Bobby Folsom

The technique that I used is to put the wing tube in a wing panel, slide the other wind panel on and push them together so that the tube hits the stops. Weight down the trailing edge just enough to keep the wing from rocking back and forth. Take two straight edges - one along the leading edge at the tip and the other from the tip as square as you can get, measure the 3.5 inches from the leading edge back and make a mark with a felt-tip pen. Do the same for the other wing tip. The next step requires some string and masking tape. At the mark on one of the wing tips, place the string and tape it so it will hold a bit of pressure, stretch the string to the other tip and tape it down on the mark. Now make a mark at the root on each wing panel. You can also put some masking tape several inches out from the root and put a mark under the string on each side.

Now you have the CG marked on each wing panel a bit away from the fuse to allow your CG apparatus to sit on the wing panels where you can see your mark. Get someone to help you hold the plane so you can see where the CG is located. I moved my batteries back to get the required locattion as a starting poing. After flying several times I moved the batteries back a bit (about 1 inch) which moved the CG back about 1/4 inch but I didn't really measure the CG again.

The Yak will fly very well at the recommended CG but for IMAC flying I like a CG that will give me only a slight nose drop on a 45 degree upline with the plane inverted.

Good luck.

Bobby
