Just measured mine at 0.730" (18.54mm). I set mine up with a very close spinner backplate-to-cowl fit (about 1/8").

What!! You got a Krill Earl

Just kidding......just miss your awesome scale "tweaks".

Hahahahahahahaha.....Very funny!

I DID get a little wet sanding and primer done today

Earle,

I have had to let mine bleed also. Murry had more on his plate than he could do so work stopped there and I'm covered up with my business. Perhaps this fall I can get it going, it's pretty close now.

Where have most you guys been placing your batteries to get a good CG?

Also, I presume a good starting point for CG is on the wing-tube?

Thanks,
Jacob

the cg is on the wing tube,but this plane flies even better with it slightly more forward say 5mm.. mine balanced spot on with an MVVS116 and their canisters with my packs on the rc tray. when I ran the lighter DA120 I did have to add quite a bit of nose weight..

Hope this helps….

also guys double check the length of standoffs needed against the type of motor you're using and the distance between the firewall and spinner backplate with a 2mm gap… I will also add that you need an extra deg of right thrust..

Finished my extra and flew it today.

All I can say is wow. It does exactly what you tell it to do, no more, no less.

Thanks for the info for setup.

I have the 31% krill. It may have been mentioned here. What are y'all doing to secure your stabs to fuzz? Dowel glued in the end of tube or splitting a dowel and putting a blind nut in it? Thanks

In my Extra 35% I have two hardwood dowel (one on each side) glued with 30' epoxy. I have drilled them all way long and fitting a long hex screw. In this way the screw do not flex into the stab composite. If you choose the blind nut with half dowel you will not have the same strength in term of flex. This is my opinion.
Hope my English is correct

Thanks Rigo

Hello everyone. This is a really nice airplane. I am really tempted to get a 30% or may be even a 35% Krill Extra. I have owned many 3DHS and EF 3d airplanes over the years. I have never built or owned a composite. I was wondering if there is a build video on this plane. or do you guys know of any un-boxing video at least? Cheers.

There is no manual. Best source I have found is on these forums. It is a different assembly than your wood arfs. But it is pretty straight forward as other arfs just few different techniques. This is my first composite as well. So far I'm liking it. If they fly as good as they look I will own more.

There's no need for instructions as it comes built, only thing needed is CG location. I have the 33% yak 55m and the quality is outstanding.

hey guys! its so nice seeing good comments about a product than the usual negatives, means a lot.

at Krill we do try our best to design and produce the best composite airframes money can buy. yes there may be a few that have minor QC issues but thats expected on a mass production like anything else and is quickly rectified. We are here to always help where we can and I personally take pride in this as I compete with their airframes too.

Hey Craig. It would be extremely helpful if you or someone could make build video for this plane. I am pretty sure it will boost the sale of this amazing plane and it will help rookies like me A LOT. Cheers.
