EDF version of my Viking pusher prop .. sea plane or slide on grass ... no undercarriage needed

This one has a 100mm larger wing and a proper airfoil .. I am using a 70mm EDF although I would think a good 64mm EDF would power it OK

Unlike most EDF jets, this one has the jet blast (or EDF exhaust) directly over the the control surfaces ( rudder and elevator) so this should make for better slow fly handling and better ground and water control

So far everything seems to be going together well .. after all parts were cut out.. about 6 hours work so far

My friend Bob ( birdofplay) suggested that we try "pocketed slots" on the wings so as the slots were not visible from the underside and it worked a treat ... we use a CNC router machine to cut out the parts, but this could be done by hand with a little care and patience .. this simply means that the slots to line up the ribs only cut into the wing about half way through

Have you heard about a new Flex CA ?
I found this at a Woodworking / Craft supplier in the USA ,
who normally has a reputation for being pricey.

It's much cheaper than HK or Hobby outlets that I found.

Thanks for the link Bob, I have emailed them to see if they ship to Australia .. and how much .. BUT, I bet its not foam safe .. OK for 3D printed parts though

Lockey

EDIT .. Nope, they don't ship CA to Oz .. FCUK em .. thats what I say

Foam safe ? ! ?

Yikes I forgot about that - Y I K E S !

I just ordered two bottles of the stuff.

I guess time will tell just how foam safe it IS or IS NOT.

I have seen the stuff at HK, but in smaller bottles and a bit priceyer

The write up says no go on foam - arrrrrgggghh ! but that's the HK of this stuff.

A N D ! while I was at the HK site I saw something referred to as RUBBER CA .. WTH ?

I guess that's one more thing to look into.

IF and ONLY IF I find anyo of these glues "workable"
I get some to ya one way or another ! ;^}

BTW are ANY of teh 90 lookey looz ever going ot participate inf this discussion ?

More build today but had to give it away for today at 40.5 degrees C it getting slightly warm in my workshop

About 5 hours work today

Hey David, how they hanging I will try and do a right turn mate .. just for you

Lockey

Right on !

Maidened the Viking EDF this morning .. MAAAAAAN does this thing fly nice .. like its on rails

Even nicer than the pusher prop version I find that quite unusual .. most of the other planes I have built as a pusher then converted to EDF seemed to be always a bit sluggish and not as responsive as the pusher prop ones .. WOW .. this one beats the pants off the pusher

Just a short flight (as I tend to do with my maidens) mainly because I cant keep my thumbs from shaking

I flew them both this morning .. EDF maiden first followed by a flight of the prop version

Sorry David, forgot the right hand turn on the EDF .. BUT .. I did remember on the Pusher Prop .. sorry guys .. just a "in" joke between David (dpalmer146) and myself

Now to put some colour trim on it
