Smacka has a problem mounting his cowl.

[Smacka]

Hi All:
I have installed the engine suggested in the manual for this bird, an OS 1.20 AX. I also installed the muffler suggested in the maunal, "for ease of installation". I cut the cooling holes and the clearance holes exactly as stated/shown in the manual, yet my cowling will not fit. The center channel of the cowling gets hung up on the bission pitts muffler tubes. I have tried to coerce the cowling in place, to the point where it may crack if I continue doing so.

What am I doing wrong? Please help....

Why another? I hadn't heard about a lot of problems with this plane.

I guess this means you cannot help?

It means that more than one has problem according your statement saying " Another Aeroworks 1.20 Yak 54 Problem"

Uh - cut the holes so your cowl fits.

And what are the other problems with these planes?

I have this plane, but not with an O.S. 1.20. This plane builds easier than a child's log cabin set. If you followed the directions you should not have any problems. Have you made the correct cuts in the cowl? I suggest you change the title of this thread to "Problem with AW 1.20 Yak", as the original is swaying the actual purpose of the thread.

Okay...if you go to RC Universe, there is an Aeroworks Support thread. In this thread of over 1500 responses, there is a myriad of issues different pilots have had with the build. One of them being my issue with the cowling BUT with a different engine, so it was zero help to me. Another example is a great many people having issues with obtaining the correct "CG" per the manual...and the like. There are more examples of build issues in the thread. If you would like to read the thread, it is under 3D flying...then the AW Support.

Did I cut the cowling correct? Who knows...as I stated, I cut the cowling exactly like the instructions stated on the section (with photographs) on how to install the OS 1.20 AX Engine.

The only reason I posted on this site is because I was hoping that someone else had built this aircraft using the OS 1.20 AX engine, and had the same issue I am having. Then, I was hoping that person would share how he/she worked through the issue so I will not unnecessarily butcher my cowling by "just cutting holes to make it fit".

It appears I have caused more waves asking for help then actually receiving help. I will now move back to the other board and leave you folks alone.

Thanks, I guess...

well your second post is not going to help you, if you act like an jack$ss your going to get these responses. Cut the cowl to fit your engine! whats the problem? No one nails the CG on the first flight, get it close and adjust it from there, I start balancing my planes by picking up the fuse from the wing tube with the wings off, once I fly it, I can adjust the CG till it works for me.

Jack$ss? Now I WILL act like a jack$ss. Stick your comment up your arse!

I am done with you cry babies...Thanks for nothing...

I have read the threads you are talking about and it seams that most of the people moving to this plane came from a trainer or a U-CAN-DO-60, at best, so the questions/problems posted on those threads are mostly the result of people that have very little experience in this hobby.
Back in my day, and I am only 33(but still have 20+ years experience), a guy would have at least a couple years of flying/building experience behind him before he moved to a 1.20 size plane. Such does not seem to be the case these days, and everyone want's instructions a first-grader can understand to build their new planes.
Yes, I have owned this plane, and converted it to electric with my OWN R/C experience. Ironically, although I no longer need the instructions for such an easy-to-assemble ARF, I did read them, and they can't get much more simple to understand.
The only problem I know of with the 1.20 Yak is the weak gear plate - a simple fix. Not being able to get a cowl to go on with ANY powerplant is a builder experience issue, not "another Aeroworks problem". It seems pretty simple to me - cut the cowl to make it fit and be done with it.

bodywerks , thank you that needed to be said a long time ago.

Dude, I was one of the first people to post in that thread and have been following and posting in it from the begininng. There are no problems! The only minor issue was the gear block and that it was built light taking away a little of the integrity. That's it. No CG problems or anything. You might be referring to the people who have been using gas engines. The plane was not designed for gas engines so obviously, it will be a lot more nose heavy due to the ignition and ignition battery. Other than that, I've got everything in the stock location with a Saito 1.80 and it balances perfectly.

I've had the plane for over a year and it still looks new! Best plane I've ever flown so far.

Maybe this will qualify as "another" yak problem?

All:
I have a build issue with this bird. I posted on RC Universe and sent emails to Aeroworks but I am dead in the water on the build until they respond. Hopefully, someone on this board has built this plane...

My issue is that for each control horn of each flight surface there are two pre-drilled sets of holes. The manual only shows one pre-drilled set of holes for each control horn installation. The manual does not mention different locations for different results or flying styles. The photos clearly show one set of pre-drilled holes.

I can understand two sets of holes (almost understand anyway) for the ailerons. This would allow for the differing length servo arms to be used and still keep the 90 degree geometry intact. But that does not explain the rudder or elevators (??).

I have no idea which set of per-drilled holes to use.

Thanks,
Smacka
