Looks good DD! Hope the maiden goes well. I have to say, I like the brown paper dodge, I'm going to file that one away for future use.

Thanks Jim, I'll give you that one Mate......wink LOL

I am looking forward to the first flight, plus I have the Boomerang to thrash....

I will post a video when she flies, that's if my Girls will do the honours with the cameras again.

Well of course i couldn't leave it without the customary photo shoot with the wheels on....laugh

It took a bit of time today as well, to get all the bits of the power train in the smallish space, but it all fits.

Also, I had recently bought 4 orange rx's from H K, the plan was to use one in The Puddle Duck, however, the first one out of the box had a faulty Throttle channel, So I have fitted a Spektrum 8 channel I had in the drawer, a bit over kill, but I know I can trust it.

The more I look at this model, the more I like the way it looks, and with the wheels on, the vintage stance just sets it off right..

In all the excitement, I had forgotten to make and add the screen, so today I cut some material and glued it on.

Always a tricky thing to do screens, but with a bit of patience, and cutting a bit here and a bit there, it all works out.

Some canopy glue and a few clamps and the job is done.

Talking about clamps I got 4 New ones from Wilko the other day, while I was killing time waiting for a rear seat to be fitted in my van. Reasonably priced at a fiver for a pack of two.

Here you can see the glue that has not yet dried, it goes clear when it does eventually dry. Normally fully cured after about 24 hours...........Zzzzzzzzzzzzzzzzzz

Ok, so today I thought I had better balance the little Puddle duck, it took 130g of the churches finest roof to balance her on the main spar. I put it , well wrapped, in the front of the cowl, under the motor.

I also did a static power test, results as follows

Half throttle 124 W @10 A

Full throttle 200 W @ 18 A

This was using 3s 2200 mah lipo, with an 11 X 6 wooden prop, the motor is the PO-2834-910 Kv (1020Kv as per the article no longer available), and a 40 A ESC, I ordered a 30 A but got a 40 for the same money so happy campers.

Numbers are well within margins and I cant see that I will need 200W but it's there just in case.

Maidened both models today....................YAY!! laugh

Both were non events, the Puddle Duck had power to spare and flew quite happily on 1/3 throttle. The first flight saw the rudder on the left stick, where it should be for mode two, but my thumbs were so rusty, that I decide to land and put the Rudder in the Aileron port (right stick), that felt better, and a more comfortable second flight ensued. I had to add 2 clicks of left trim and thats all.

Well chuffed..

The Boomer was the same, I put the watt meter on her before the maiden. The recommended prop is 14X7 on 4 cells, I used a 13x7, as I was worried about ground clearance, with the field grass being a bit tall.

I got 500 W at 30 A I reckon I would see 600 W with the 14x7. Same with 5 cells and a 13, also there is an option for 6 cells with a 12x6.

Happy campers.....laugh

Video of Puddle Duck to follow.

Looks like a great day out DD, good to see the Puddleduck in the air!

With rudder/elevator models I always have the rudder on the right stick - the way I look at it, mode two puts the primary roll control on the right stick. With a four channel model this would be the ailerons but for a three channel model it will always be the rudder. Hope you get plenty more flights in over the summer!

Yes Jim, it makes perfect sense, and it made for a smoother flight.

It's a cracking little model, and I think it would handle a bit of wind too.........

Keep 'em coming Matey..laugh

I also fly mode 2 and on rudder/elevator models I mix rudder and aileron 100% so I can use either stick. I found if I put the rudder on the aileron channel I was wiggling the left stick (rudder) on take off and it was having zero effect because there was nowt connected to it

Well DD your Puddleduck looks great. However that's the quiet, sunny, no wind day for 2018 so you might as well put it away ready for next year yes

That is a good idea Geoff, I may well nick it....wink I too was wiggling sticks and wondering why there was no response..................

Thanks for the compliment by the way, I'm quietly optimistic for some more nice weather, however, that's why I built the boomerang......to fly on all the other days. laughlaugh

Right, I've taken the plans out of the mag, and put them in a nice clean plastic folder. Come the glorious (or not) day that my Stevens Aeromodel Skybuggy gives up the ghost, I'll build the Puddle Duck...
