I have about 20 flights on my 50cc AW Yak. It’s a newer release so it has the mods and all is well. Has anyone weighed your yak?
Mines at 19lb 13oz with an Evolution 58, pilot, and dash added. It seems heavy but flies lite.

I'm about 4 flights on the newest version using the 3W55i and I'm right at 19lbs. It still flies like the first one did at 18lbs with a DA50 in it but it does have better vertical. I have not really wrung it out yet so I cannot say what kind of rock, if any, it has

Hello,
I just wanted to remind everyone when you receive your kits to inspect everything for damage right away. I did a quick inventory and check when I got my AW 50cc YAK 54. I did not un wrap the wings which are now shipped in a separate box.
I started assembly last weekend to find on wing had some damage. It is not major, but required removal of the covering and repairing three crushed ribs and some sheeting. I was told it is non structural damage. Non the less it was extra work to repair that could have been avoided if I would of inspected everything in detail shortly after receiving the boxes. I really like the kit & hardware and it will be ready to maiden shortly.

Bottom line... Inspect everthing as soon as you can.

Chuck

Thats right I allways check all my kits when they come in. It makes my hair stand on end when I here guys say they are going to build it later and not going to even open the box till then. That is a big mistake for sure. The 50 cc Yak is a sweet plane I have the New Extra 260 coming I just talked to Rocco on Friday and its shipping out next week. From all reports its a better flying bird than the Yak. But will see. It is 1 pound lighter right out of the box from what I,m told. There will be a build thread started soon for the Extra stay tuned. My Yak is flying real good I had it dialed in untill last week when I had to dead stick it into the corn field. It took the crash landing pretty good. My wings where totaled but the rest of the plane made it ok. WOW was I lucky. I ordered a new set of wings that where in stock!! They will be shipping out with the new Extra 260 next week. Yhe Yak will be back in action by next weekend. I,m having Yak withdraw!!!

This has probably been beat into the ground on other threads, BUT.... I have mild wing rock when trying to fly an upright harrier or descending elevator with full up elevator at idle. Inverted the plane is stable with maybe just the slightest hint of rock. I'm flying with 1 1/4" arms on my 5945's on the stabs and perhaps not getting the full throw required for this maneuver. My CG is aft of what is called for by the directions with initial setup and is virtually dead neutral upright, inverted and on the inverted 45 degree lines. I don't want to move it back more than perhaps a 1/8 to 1/4" at max.

Question is: Do I simply need more elevator throw, or do I need to move the CG back to a magical point?

I have mine at 16-lbs-15oz. However, this is based on my memory. Could be a bit lighter. I just don't want to under report. I wrote it down yesterday and don't have it with me. DA-50, canister, no pants, carbon gear, carbon spinner, carbon tube, wood prop., 3 TBM lions and miracle switches. 5925's and 5945 rudder. All from
TBM. How does this compare?

Neither put flapperons on your side sliders if you have them and programme in 1/4" up on both ailerons, the rocking will dissapear.

Thanks, Mike. I will have some time next week to try the spoilerons mix. Changed to 5955's all the way around. By the way, I went to a 23A Vess prop and love it. Great hover at 1/2 throttle and a whole lot of braking on the down line or coming hot on approach.

Thins have been pretty quite on this thread. Did everyone go somewhere else? The planes been out awhile but there has to be someone still interested in talking about it.

My AUW is 17-lbs-3oz. But after reading this entire thread, she's fixin to get a little heavier. I added the parts AW sent to reinforce the gear but it doesn't look like that will come even close to making it dumb thumb proof. I went with the 3" standoffs to help with the balance. My kit is issue 1 and I think ill fix the wing with 1/4 plastic bolts and then for the second method just connect the two wing halves with a strap if nothing gets in the way. This way only one connection attaches two wings.

I really like the looks and the engineering. It is easy to reinforce the plane to make it a bit more durable but it would be heck to make it lighter if it were idiot proofed. Anyhow, I like is so much, I want a bigger one. Any thoughts on the 100cc? I have my name on the list for the 100cc - 260 and I may change my mind cause I really like having something to open on Christmas day. Can you feel my pain?

I have been flying flying mine since they came out with the first run and I really like to fly this plane. Since I did the initial modifications I had no problems. i been changing the CG around allot and haven't found the sweet spot yet. Anyone care to say where they found she likes it I been as far back as 5" and now moved up front back to 41/4 as in the manual.

Hey guys,

Just an update to this thread. I have close to 100 flights on mine now. I'm still using the 3W55i but went to the KS1060 tuned pipe and the Vess 23B prop. I removed the spinner and pants and added smoke and I'm still right at 19lbs but what a difference in vertical the pipe gives me.

Here are a few pics from the other evening just as the sun was setting


Buzzard,

I cannot say where my CG is but I can tell you that with a full tank of fuel, I can go inverted on a 45 degree upline and let go of the sticks and she just continues going up without lowering or raising the nose, It hovers just fine at this setting and still does sequences well, in other words I'm very neutral

Question for you. Did you have to use standoffs when you mounted your 3W55i? If so how long are they?
I'm mounting one on my new Yak and wondered if I will need them.

Thanks

you do need them ,but for the life of me I cannot remember the length, sorry

It's not hard to figure out, get the length of the engine and look up the length from the firewall to the cowl in the planes manual, subtract the engine length from the number in the manual and there ya go.

My 50cc Aeroworks Yak arrived today. The DA50 from Chief has already shipped. I hope to get it this week. I am still trying to decide on the radio equipment. I plan on reading this entire thread. I can't wait to get mine flying. I have been in the sport since the early 80s. I still cannot get over the quality of today's ARFs.

I"m going to start to build my YAK 50 cc next week. I'm using a DA 50 for it. How long should the motor standoffs be? 2 1/2 or 3 inches?

THanks for the response

Chuck

You'll want to go with the 2 1/2 inch stand-offs. For some reason, mine came with 3 inch versions and I got some of the shorter ones from DA. 2 1/2 inches gives you perfect distance from front of cowl to the spinner backplate. You can look in my gallery and see what the spacing looks like. Good luck !!

I actually bought my DA-50 from Tom at Wild Hare when I bought my Extra 300 from them. For that aircraft, the 3 inch stand-offs were needed in addition to a 1/4 inch spacer. For the Yak, I needed the 2 1/2 versions, so I called DA up and bought them for about 7 dollars a piece. I don't know since I didn't try, but you may be able to swap them out for the other size through DA. Never know, give it a try...

How did you setup the carb servo for your 3W 50? I have one and can't determine the best position for the carb servo, given the location of the carb when the motor is installed (carb is on the bottom).

Thanks,

It's easy. I soldered the arm they give you onto the carb so that it points down. Then I cutout a little more of the lightening hole on the left side about 2 inches back from the front former where the cowl lines up with which places it just in front of the fuel tank, so that the servo would fit in. Then I glued a small piece of 1/4 inch balsa block to the front of the cutout under the front servo ount screws to get it to line up better, waited for the glue to dry and mounted everything. Worked like a charm

Hey guys,

I'm still using the 3W55i but went to the KS1060 tuned pipe and the Vess 23B prop.



Can you say what kind of RPM or thrust numbers you are getting out of this setup before and or after the KS-Vess add on?

Thanks,

Richard

Richard,

I do not remember the numbers but the original setup with the 3W "L" can and going to the KS pipe gave me close to 600rpm more on the PT model 23x8. I lost a little rpm with the Vess 23B but gained tons of vertical pull. At full throttle with the current combo it's at 89Db so it's very quiet. Guys flying 2 stroke glows and 4-stroke glows cannot hear my plane over theirs

The main thing is I was a tad nose heavy with the can and the pipe put it right where like it and this included having the twin Fromeco 2400's sitting on both sides of the rudder servo

I purchased the motor from a buddy and it did not have the carb arm. I make the modification you indicated and move forward.
