Well it is not a cool as Matt's but I am not going to do much more to this ARC Akrobat.

As Joe Gilbert says.... it's a tool.

Came in a little over 53oz.

LA .46, clunk tank on pressure.

Will test it out this weekend at our Spring Fling.

PS- Thanks to my friend Louis Rankin for helping me get the wing and stab in and dialed in. And that Slacker guy on the Tech support line that was there most of the time to answer my stupid questions. (Zuriel Armstrong)

What a beautiful white canvas for some color! I love the Sig Akrobat. Flight report please.

Isn't this the one that was posted recently as being way noseheavy?

Yep.
You can not see it in the photo, but there is a brick tied to the tail.

We will see what happens this weekend.

OK, so maybe I'm living in a closet. But what is an AKROBAT? See no mention of same in ARF column. Thought it might be a Sig something, but, un-unh...Would it be suitable for an OS .46 VF and a pipe? What size? etc.

Paul,

Slacker here. That looks great. You are supposed to use the brick for a stooge, not install it

. I look forward to seeing it fly and I'll bet you will be suprised how well it does. Nice and easy now.

Paul, where did this kit come from? Are they back on the market, now? I bought one from a hobby shop, years ago, that was supposedly ready to fly (Fox 35 installed, etc.). Never could get the engine to run. Surgery followed. Tank had been installed with the pickup on the inboard side of the plane. Pretty smart, huh? Plane was later destroyed when a train derailed and went through my storage shed.
I've tried to find a kit, but Sig doesn't make them anymore.
Just wondering.............Glen Wearden

Ward - It was made my SIG, and I got this from someone's estate. It was mostly ready to go together but needed some minor fixes and upgrades.

And no they are no longer on SIG's site. You can get the Akromaster or the Chipmunk.

And I will need the Tech support guy to look this over before I fly it.

I love the simple paint scheme. But, if you had loaded it down with all of the color garbage it might have came out tail heavy. Looks like it should fly great.

Paul Taylor · « **Reply #9 on:** May 20, 2010, 09:12:33 AM »

Good thought Doc,
Maybe I will put my AMA number an all the trim color on the tail.

Harleyman · « **Reply #10 on:** May 20, 2010, 11:19:59 AM »

You've done a great job bringing it back to a flyable state.

Give me a call form the field with a report. Can't wait to hear how it flies.

wwwarbird · « **Reply #11 on:** May 20, 2010, 11:15:18 PM »

Ready to fly, what does the plane weigh not counting the weight you've added to the tail?

Paul Taylor · « **Reply #12 on:** May 21, 2010, 06:33:20 AM »

Wayne,
I had to add about 3.25oz to the tail to get the CG just in front of the spar. Start from there and hope I will not have to add more.

wwwarbird · « **Reply #13 on:** May 21, 2010, 05:57:45 PM »

Paul,

Please re-read my last question.

Paul Taylor · « **Reply #14 on:** May 21, 2010, 06:06:07 PM »

50oz

Randy Ryan · « **Reply #15 on:** May 21, 2010, 06:07:50 PM »

Looks GREAT Paul!!!

wwwarbird · « **Reply #16 on:** May 21, 2010, 10:32:39 PM »

Thanks Paul.

This is good to know, 50oz should be a totally acceptable overall weight for that airplane. In my opinion many people overcomplicate and overthink a lot of this stuff for the average flier. I recommend sticking to the basics. If it was me in this case, I would take off the tail weight you've added and go out and fly it, just to see what you think. Noseheavy is safe for some test flying on a plane this size, even if it's somewhat excessive. You might be suprised and be just fine with it. I never get too hung up on a CG location from any plans, just see that the model not tailheavy hanging from the thickest point of the airfoil, and go test fly. Beyond that, just trim it to your personal preference.

If it turns out to fly OK I will add some color. But it will be very little and very light!

john e. holliday · « **Reply #19 on:** May 22, 2010, 09:35:17 AM »

Also if you have the adjustable leadouts, hang it by the forward leadout to see if it is nose down. If it does that is good for a start. Once flown then you can start triming to your preference. Make sure there is enough wing tip weight also.
