i have also put some thin stripes of selfadhesive black tape under these pink collars and when i screwed everything it just won't move.
Maybe not today but sometime in the future it will. It is not good to use adhesive around a clamp unless you have a way of tightening the clamp after the adhesive cold flows. In the tape industry there is a term called “blocking”. Blocking occurs when the tape is wound too tight on the roll and the adhesive cold flows out to the edges and bonds with successive layers. Have you ever had a roll of tape that just keeps ripping as you try to peel it? Anyway, when the sun hits your boom and warms up the adhesive it will ooze out to the edges. This in a sense decreases the diameter and loosens up the clamp. With the fiber board between the clamp you can not tighten it up. You may see problems in the future so keep an eye on it.

In your original photos this servo wasn’t there. It appears as though the servo was forward mount which on most helis is an upgrade. Did you change this to rear mount?

Other observations:
It looks like the control rod is very close to the mounting screw to the clamp in the photo. Make sure they don’t make contact or you will suffer RF interference. There appears to be a shield / ground around your HT wire. Get rid of it.
one last question. has anyone used FMA copilot? is it any good? does it really work?
Yes, maybe, yes.

I learned to fly my Predator with the FS8 copilot. It works very well but on a gasser it requires opto isolators on every channel and a separate battery that only supplies the receiver. Luck would have it my power switch failed on the receiver and that resulted in a chicken dance. If you add the cost of the opto isolators to the FS8 you are almost the same as the APi2000 stabilizer. The APi will give you the benefit of a PCM receiver. I switched both my helis to the APi stabilizer. Without the need for the isolators my receiver is backed up by my Jewel generator so even if the switch fails I won’t loose control.

You have been experiencing some problems that may be generating RF. Unless your ship is pristine to begin with I wouldn’t go the FMA copilot route.

What could be more fun?

thanx AceBird for the info about tape issue. i will make sure to check it from time to time. the clamps hold the tail firmly even without tape. i just fell like there should be something soft between metals. so i just stuck 3 small pieces of very thin tape. but it's just tape on metal not tape on tape. it's only one layer. when i tightened the screws it's just rock solid. you are right factory placed the tail servo way up front. my control rod is more than one 110cm and it's not in a straight line. that's why i decided to move the servo to the tail. i made my new control rod from carbon. it's about 65cm and now it moves really freely. i think it will be a good solution. well actually i will check that out when i have everything ready for my first flight. the rod you see on the first picture is the original one and the servo mount was just put there for the pic but it wasn't finished yet. on the second picture all is finished. nothing touches the screws. anyway i will do my range check before first flight.

Nothing is easy in this life . so i have ordered a wt 644 carb and i received WA 213a. it's supposed to be for 230puh engine. can't find any info on this carb on the net except for plenty of pages with replacement parts. does anybody know what kind of carb it is?. it must be petrol i guess ( priming bulb) but how does it compare to wt 644?
this time i will skip buying through local rcshop. i have ordered wt644 directly from the states. so i will be waiting some more but i wanna see this bird in the air so if somebody knows WA213a and it can be used then i want to try flying with this carburator.

well so it's not a problem. people use wa 213 with PUH230 engines. so i guess i can spend some time today to fine tune the needles and maybe try to hover.

P.S. pozdrowienia z Lublina

Almost finished. Will have to use black maverick blades although i prefer white funkey blades. But somehow i can't tune blade tracking on the white blades. I really don't know what can be wrong, they are exactly the same, weigh the same, bend the same under pressure. Maverick blades work without any problem. So as i said it's almost finished. Will have to do something about the tail serwo, i just don't like the wires sticking out of it from behind, and i will have to connect and program gv-1 later. the magnets are allready mounted. I will have to wait for better weather. It's very windy for the past few days, up to 120km/h so no flying in these conditions. All i did up till now was to fire it up a few times on the ground to fine tune the engine and blade tracking.

I have a hirobo eagle sst II standing in the basement. os nitro version. I know that these machines were also with a petrol engine. I wonder if i could rebuild it to fit a zenoah engine in it. I think it would be a great flier. I just don't know how mamy things or parts i would have to remake to make it work. If anyone has this machine with a gas engine i would be very much interested in some data about it and some pics to see how it looks.

well next post i think will be the last. hope to upload some video of how it hovers.
