lovin' hobbyking

I've been using hxt 900 and hxt500 for a while. Make sure you order replacement gear sets if you make an order to the US.

btw, I've also been using hyperion digital servos of all types from allerc.com for all my builds that are 'hi end digital worthy' for a while... they are great, and cheap for what you get. USB programmable!

I never realised I was so transparent!!
I was going to send it to "Layer"
Steve also knows that they only get better....towards the end.

Well... The lay-up is finished
The rear opening makes the seaming a lot easier and stronger.
We'll let her mutate for a while..
She could be all nice and shiny inside...
Pity about the fish eyes!

Hey Layer
What slopes do you guys have around you?
And... Wind conditions?

I suppose it's a leading question.
Sean's just broken the news..
The 1st one is a "lead sled" of note!!

Back to the drawing board!

Sorry to hear that...
Setbacks are always a leap forward!

All kinds of winds and conditions...

Inland and coast, we have a long coast line so there is no problem finding places to fly!
Cliffs, round tops, deep or shallow U name it...

I however am a lucky guy, 2min from my house I have a fairly good slope to do my tryouts and fly my wings... Not the ***** standard but there are worst places!
15/30min drive to the coast and there U can choose depending on direction...
The wind usually in this time of the year (summer) is N/NW and average 10/15 knots going up...
Calm mornings, and strong towards the afternoons almost everyday!

I usually fly alone, always looking for new places... don't like crowded skies...

first layup done...

hi all.... I polished up my mold last night, using a 'flannel' buffing wheel from Dico with tap plastics fine scratch remover worked better than I expected. I chucked up the bufffing wheel in my cordless drill on low.

I layed up 3.7oz x 1 and 5.6 oz x 1 on the bias, using a template. It went OK. My first real mold layup!

I'll post a pic when I pop it out later tonight.



(BTW: Whats the purpose of the mold clamping bolts?? why do you need to clamp it? Its not going to move on its own is it? Does it allow better manipulation for seaming etc, and not worry about shifting? It seems like the curing process (barring use of silicone inserts or bladders) doesnt need all the pressure. Just wondering.)

We're having a great "show and tell"

Sooo...
The next one is out!
A few steps forward!! (at last)
So, besides the fish-eye...
She looks great!
All shiny, neat and....
70g
Yeah!!!
She's strong enough and clothed!
The last one weighed 92g and no colour
If you were to take Ben's Tail at 11g, and +- Dave's 39g for his pod..
Not looking to bad!!

Fingers crossed Ben!!!
By the sound of things,
You have followed the textbook to a T!
I'm sure it will be great!!

Johann that new fuse is surly a thing of beauty,
I really like it.

When you guys figure out what should be changed
in the extensive flight tests I know she be through (All around the world)
maybe I will have to make a Sally 2.0 for my next project.

A light/medium wind sloper would be prefect for my local spots
My Jart is just slope bling for those awesome days.

Hi Alex
I could not agree with you more...
We had a good laugh today when Sean was explaining the follies of my ways as regards weight..
And to reinforce his point he said " I think your heavy wind Quiver is now full"
And, he's right! Those perfect, straight up the slope heavy wind days are few and far in between....
We have more light to medium days expressed as a percentage...
Soooo...
Why don't we have more of those planes????
I've come to realize, I can't build that light...
Not in composite anyway!
So I've joined the Alula and Weasel fraternity!
Just buy and fly!
Really relaxed flying without holding on to the seat of your pants stuff!
(for someone who vowed that he'll never fly one of those!!)

Thanks Ben
The paint is a two part automotive paint known here as 2K
Pretty toxic as far as i know and contains arsenic in the hardener...
I don't know about the US, but in some countries it has been taken of the shelves..
I sprayed and then left for an hour and went right in!
The wax is a problem in that the paint fish-eyes..
I'll try to spray lighter dusting layers..
lets see...

So true Johann we spend all this time
building planes that can be flown maybe 10% of the year.
What about the rest?

I do have my beat up Zaggi,
my first and general light/med day sloper
but I've grown very bored of it.

I learned as many tricks as it can do with it
and I would like something a little more fun to fly.
I too vowed not to buy another plane if
I could make something similar with my own two hands.

I was hoping the composites would be the key to that,
but composites seem to be too heavy unless you
somehow master the weight problem or refine the design.

Maybe I should invest in a large block of EPP and see what I can
make from it. I just really don't like the look of foamies they seem
cheap and only out of necessity.

I guess I better change my ways of thinking about EPP/Foam
