New build - RCME Bambina
« on: December 18, 2017, 19:23:55 PM »
I know it's not ideal perhaps in Irish weather, but at £15 for the laser cut kit, I decided it's worth a shot.

It's slow going with perhaps 10 minutes in an unheated attic at a time.  Not because I'm a wuss and can't handle the cold...  ;). Well, maybe partially that.

Started off with the fuselage... Didn't have anything else square to hold the corners in place...


But it seems to be square...   :D


Started on the wing to allow procrastination for fitting the motor.


Then the other, and join them.  Which I think may have been a mistake, since I need to shape the leading edge yet.


None the less, onto the tail plane and fin...


At 31" wingspan, she's a dinky little thing.  3 axis stabilisation will likely be required...

Looking good  8) and looks like a fast built too!

You have a photo of the finished model?

Fast? Perhaps in time spent actually building... I've had the model for s month so far.

I'll post the finished item when I get to that stage...  ;)

Finally got back into the (cold) attic again for another few nights of small bits and pieces.

Upper wing centre sheeting


Wingtips


Wing underside sheeting started...


And finished.


Back to the fuselage, with the rear lower decking getting glued in...


And a test fit of where the wing servo will go...

Vital addition to the "shed"  ::)  A heater!


I know self-praise is no praise, but it's certainly a lot tidier than building the skylark!



Wing assembly is complete.  The upper side of the LE is roughly formed, so the final shaping is next on the agenda.

This is all I'm seeing David.

That is because he uses Photobucket, not the forum Hosting :(

I don't see them either at work as this is blocked. And the older photos are all gone  :'(

I'll have to fix the photos...
I thought I'd be smart and use Google Photos, but while I can see see the photos, it looks like the rest of you can't.  :(

What's the forum hosting? Using the attachments?

Yeah, put that on the forum directly, better :)
And you can do it from your phone also etc etc. Plenty of room, and nothing will get lost or deleted/removed :)

When you create or reply to a message, simply do the below. You can put up to 30 attachments in a post. Let me know if this works for you :)

Hopefully all the pictures are visible now!  I changed the hosting and also attached directly here.  Overkill, perhaps.

Anyway, I shall duly continue with attaching photos here.

The LE is closer to it's final shape and it seems to fit the fuselage rather cleanly.

The motor is miniscule, but is supposed to be capable of chucking out 135W!  :o  It'll be running off an 18A ESC and a 7.4v 800mAh lipo.  The mount is fitted to the firewall, but the grub screws need an allen key of <1mm!  Fitting could be a problem...

Thankfully, I seem to have been capable to keep everything square and tidy.  I think building is strange in that you don't seem to make much progress any night I get to it, yet it's taking shape really quickly.

All good, can see your photos now  :-*

And you are right, this motor is tiny!! (I know nothing about electrics, so I will not comment further  :-[ )

Anyway, looks like a nice and clean build!

Ah, now I can see what you're talking about! :)

Much easier to work on stuff when you have an assigned room, rather than on the kitchen table isn't it. Can be a wee bit chilly in the attic though. I had an attic workshop for years and found it cold in winter and hot in summer, but beggars can't be choosers. At least you have somewhere. (I found fingerless gloves a benefit during the winter. And a woolly hat. Ha!)

Well, it all seems to be coming together quite nicely. Did the motor come with the kit or have you just purchased one that they recommended?
Looking at the wing leading edge, is that the final shape or does it need a bit more "rounding"? From the picture it looks a little 'flat fronted' David.
You're certainly getting on with it!

It is easier in an assigned area... It just needs assigned time!  But, I can't complain, she did donate the heater!  Unless she intends to make me move into the attic...  :'(

The motor was selected based on the specs supplied on the plan. I'm going to make the cowl removable, somehow, so that I can change it out, if I need to.  But I'm hoping I picked correctly!  You are perfectly correct, Keith, the wing is still "in progress" for sanding.

Thank you Keith! Having checked the specs of the motor I purchased, I find it can only tolerate 7.4V, not the 11.1V I need.   :-[  The appropriate motor has now been purchased.

A bit more work finishing off the bottom of the fuselage this evening and sanding the LE and wingtips to the correct shape.  I think I'm mostly there.

Just out of interest, what size prop will you be using David? Due you have any idea of the intended All Up Weight of the model? (including the motor and battery)
