Default balancing 86"

I'm finished assembling the new 86" Yak per the manual less the canister. I used the stock muffler that comes with the DL 50. It seems to balance very tail heavy. Is this to be expected?

Wasnt there a recommendation for an aluminum spinner with lightened backplate listed in the instruction manual? Anyhow, as with every airplane. Move the batery pack until it balances. [sm=idea.gif]

I'm going to maiden the new Yak tomorrow, we'll see how it goes. I don't have a spinner but I don't think a spinner alone will make that much of a difference on CG. I'm also using the stock side muffler that came with the DL50. I'm guessing with a canister set up and spinner the plane would balance as per manual. I had to move the receiver pack up into the motor box and added an old transmitter battery pack to get the correct balance.

Mine was pretty tail heavy. I have a spinner and both battery packs on the engine box. I still had to add 4 ozs to the nose to get it to balance. After a few flights though I started to remove the added weight and finally removed all of it. I love the way it flys, still a little tail heavy I suppose but I love it. It does make landing a little more difficult but it flys just wonderful. This is an excellent flying plane.
Thanks
Barry

YEAH........ maiden went as well as expected.... Another validation to a brand I've been partial to for a long time.

I wasn't sure that I would be as please with a smaller version of my 102", however I am no less impressed.

I'm using the DL 50 so I took it easy on the 3 flights today. These engines are not run at the factory so I'm taking it easy. BUT THE POWER IS AWESOME.... I think I'm going to like the DL, runs like a charm...

I don't like the standard side exhaust as I had to chop a lot of the cowl, and it's loud. I'm going to order a new cowl and probably get a pitts style muffler or canister in the near future.


Just though i'd share my experience.

Hi,

How much fuel have you had when balancing?
