img_1152.jpgI started with a bit of dismantling. It's easier to work on without the tail, and I have plans to replace the central elevator servo with two in the tail.

The plane used to have an OS60GT and I have plans for something very different, so the holes in the cowl had to be filled.

Thanks John, it was certainly well looked after by the previous owner.

Hope you don't mind me asking Rich, but why are you planning on replacing the central servo with tail mounted ones?

In my opinion, pull-pull controls are the best there is.

Interesting comment, but I've never come across separate elevator halves on a pull pull system and on a single servo (I believe that was the setup)? Not saying it doesn't work well. My main reason for changing was because I am using a slightly heavier motor than what was used previously - the model was designed around the heavy Zenoah 62, so weight not an issue!

Cheers! There appears to be no damage at all, just very minor wear and tear.

I used to use the pull/pull cable system with a single servo on the elevators for 2 reasons. Mainly because my radio at the time couldn't satisfactorily set up the ailevator method to drive two servos and second I always thought it was more precise.

However, I don't go that route now because I now have a decent computer radio that I can programme using two elevator servos. Also using a single servo usually meant a couple of mods to the fuz and it is a pain to get the wire tension right. Lastly, I am not convinced that the cable system is and more positive than using 2 short pushrods and 2 servos.

How did you find the setup Adrian? Did you notice much difference?

Opinion seems very divided on this issue, I think it comes down to personal preference, but I'm with you Adrian, push rods seem more accurate/less slop to me. yes

I understand the logic for converting if the CoG needs moving rearwards.

I also understand that pull-pull can be tricky to set up in the first place for the reasons given by Adrian. As the model is already set up for pull-pull though, it shouldn't be too difficult to get it working again. Just a thought before you dis-count the option of keeping it as it is.

Edit - you posted as I was typing. Best way is whatever you prefer.

As Gary says it's personal preference. That said I get on with the twin servos much better and using the sub trim when setting up the elevators negates the rolling out of a loop sometimes caused by uneven tension on the cables in the pull\pull method. I just like the simplicity of using a decent radio to help with the job. Clearly, depending on the CoG weight distribution this may not be as agreeable. I am a bit hamfisted, but I found it took me a good couple of hours to set up the cables while I spend less than an hour using the two servos setup.

Best way is a short pushrod if model allows it, n ball links whilst we are at it wink

That's my preference.

As Gary suggested, I may just wait until I know where I stand in regards to the cog.

The motor has turned up! My first DA, any guesses on what it might be? wink

DA motors do not come with headers/mufflers, who knew? I didn't factor that in! So now I have to research the options for the exhaust...

John

p.s have a look on bmfa, lma, high alpha, they come on quite a lot.
