Ken, that is a really great weight with that size battery. Nicely done. Best of luck with your maiden flight!

Hi Tallflyer,

The CG is dead on! and that is without the battery. So my battery is held with velcro right at the CG. Easy to make battery changes without upsettting the CG. Mounted the aileron servo in the plans position and adjusted rudder and elevator servos to set it up. Also used Dan's pic's as a basis where they should go.

T minus 04:45:00 and counting to launch.

Mark, sounds good. I'll be ther 1-5 today, flying thursday (not working ), 1-8 Friday, 10-6 Saturday. I'll try to get it built this morning just in case.

Ken, 600mAh? That thing should fly what? Half an hour? You'd only need 2 or 3 packs for a weekend worth of flying.

Recently Welders glue has been difficult to find at Walmart not just in my area, but in other areas of the country as well. I contacted Homax the manufacture of the product with the following:

Customer support,

I would like to inquire about the following product. I have been using the Welders industrial strength contact adhesive that is packaged in a red tube. The product was readily available at Wal-Mart, but recently it has been very difficult to locate. A search of the Homax website showed Welders glue in a grey or silver tube. The question, are these two products the same and just packaged different? I have attached images of the two products.

Best regards,

Mark


The response from Homax:

Mark,

You are correct! The first picture was the older look and now the welder is available in the silver tube. You can usually locate this at Lowes stores.

Please let me know if you have any further questions.

Regard,

FLuffy Yak Flight Report

All I can say is "YESSS!"

The Fluffy Yak is all that. Very nice flights at lunch. Had a small group of engineers asking all kinds of questions to which I had answers. This one will put you on the fast track to hovering as well as other manuevers. Now I need to take it to a larger venue to practice. At the close of the flight some others came by asking questions, so I plugged the battery back in, gave it about half throttle and she climbed slowly vertical up to about 10 feet, where I back the power down and she came right back to my hand, without torqueing (I was lucky), or yawing, but looked fully intentional.

Flights were nice and slow with very little power required to stay aloft. This aircraft is all that I had hoped for and more.

Now go get Yakked,
Ken

I just picked up a package last week at Wal-Mart. It was the older one with two tubes, a large one and a small one. I noticed it was red tagged and a reduced clearance price. This explains why.

Thx

Congratulations Ken! It really makes my day to hear a flight report like this.

Dan,

I thought is was a fluke that this thing hovered so easily that time in the previous post, but I showed a couple of guys on second shift the plane by turning on everything and with the TX sitting on my work bench adjusted the throttle to climb very slowly. Pointing it straight up, I could let it go and hang there unassisted for about 3-5 seconds and grab it before it climbed out of reach. Repeated this several times. What a trip! Must have got the trims and lateral balance just right (accidently).

Looks like more Fluffy yaks are getting built and flying. For those who have asked I now have some more 1.0 EPP on hand. I put together a simple order sheet to make ordering easier. Go to http://www.emailmeform.com/fid.php?formid=249057 to make an order. Eventually I will have a regular web site up and going.
Thanks.
Mike

Tallflyer, What is the AUW on yours with that setup? Mine is almost identical except for a 9050 prop. Tested AUW with a 3S 610 and it came to 8.1oz. I think with a 2 cell it will be in the high 6 to low 7 oz range. Get to fly it for the first time tomorrow night at the indoor event in Eden NC!!!

Diggs

OH, forgot to mention my foam isn't really 9mm. I ordered 9mm but it is actually about 10.2 mm

My plane on the scale with no pack is at 5.4oz
with the battery I practice with 5oomah takes it up to 6.5oz If I went with a 300mah I could save more weight also.

but at 6.5oz AUW I'm happy
