Thread: Elevator Trim
19/04/2009 17:35:50
Well, I moved the battery to the rear a little and it made no difference - I still needed up trim.
The really strange thing was when inverted it needed up elevator to maintain level flight and not down. I must admit, I only had one flight today and will double check later in the week and do the "diving" test.
Thanks for the input so far.
PS - Timbo, nice of you to say so!

Well I balanced with an empty tank and used a jig made out of copper tubing which allows me to balance the plance. As below, albeit with a different model:

I moved the battery etc until it balanced level at the mid point of the recommended range.

Thanks for the replies gents.
I'll move the CofG back a bit and she what effect the has. I will also look at the thead you mentioned. Thanks again.

In order for my plane (a large Yak) to fly straight and level I am required to hold in up elevator. When trimmed there is a few degrees of up elevator required.
My question is what could be causing this? The engine has no down thrust (as specified) and the CofG is as per the recommendations.
Any thoughts would be welcomed.

OK - for those who may be interested I have started a build thread on our club website:

You will fond it under the News section and Items of Interest

Was about to start a build thread on this forum but have decided against it.

Don't like the fact I have to upload my images to seperate server first and paste the url into the post. Also, there is no preview option.

So, for those who are interested I will add the thread to my club website and add a link once I have done so.

Hi Graham

Sounds like I will end up with a very similar setup to you. I did get the cnc pack - which when I added on the cost of the "additional" wood pack found to be quite an expensive combination.

Anyway, I have started and got the wings about ready for sheeting.

Like you, I am not sure what to cover it with but am leaning towards the epoxy/glass solution. Film always tends to wrinkle in hot weather and if it is a painted surface I am worried the paint may crack.

David, I may well start a blog - once I have figured out how to!

I have just started to this model and was wondering if anyone has as yet posted a "build thread" with pictures?
