2nd year in the hobby, 2nd BluBaby ready for takeoff

I infected a friend of mine with the virus of rc-flying by taking him with me a couple of times and handing him an X-twin ("AirHogs" in the US afaik).

He wants to get into flying "real" rc planes but seems to be resistant to the scratchbuild-virus.
So for the last couple of weeks he kept asking my advice about what RTF to buy. But since all my planes are scratchbuilt and I have never flown any RTF I really couldnt help him. (I know the EasyStar would propably work, but that is a pretty expensive plane too)

Long story short:
I bought a HK 2.4Ghz Tx and built a BluBaby from stuff that I had.
After only one year in scratchbuilding myself I really had Esc, Motor, foam, servos, even wheels in the drawer

Hope to maiden this baby next weekend and hopefully will get my friend on the sticks soon. He already managed to fly my Mini Cassut a bit, so the BluBaby should be no problem at all.
In my opinion this is the best platform to learn on.

You can use any type of water based paint, or you can use a clearcoat water base then spray paint it with regular acetone type paints. It's been suggested to scuff up any tape for better adhession. Alot of these guys use airbrushes which turns out fantastic. I've painted my before with a brush and didn't like 'cause of all the brush strokes seen in the paint. As soon as I can I'm buying an airbrushes and mini hobby compressor.

This one has the exact same setup as my own BB (1600kv Emax):

Here's a video of mine:

*edit*
btw, I used createx airbrush colors on this plane. I dont know if this brand is available outside EU, but I really like it a lot because its water based, easy to use and works on pretty much any surface.

Very nice looking BB. Your friend should be thrilled!
My flying buddies and I have decided we like the Oskosh Special even better than the original BB. It is a great trainer with small stick and surface movements and yet it will do some great acrobatics when your ready. Vertical climb outs, basic hovering, inside and outside loops, and even inverted. All that with the slow flying UC wing. Yet any time you can let go the sticks and it will recover nicely.

LOL. I like the BB assembly line. I almost built two BBs at the same time. I did accidentally cut a KFm3 wing before I realized that I really wanted an UC Kfm5b. So,I have a wing, a top fuse, a bottom fuse, and an extra rudder (the latter three being extras that were cut from the scraps). Since I have seconds of almost everything, and I am going to start on a second tonight...

Blu Baby cousin Blu Dragonfly

I love the Blu Baby... Thank you all who had a part in sharing it with all of us.
I built and flew a couple now and it is in my blood to change things. I know with air planes changing thing can make things go wrong fast. Well I changed the looks a lot leaving wing distance the same and I seems to fly great. NASA watch out here I come. enjoy and if anyone likes I will share PDF of layouts or what ever. Sense the video I have put a bigger motor on and it flies even better.

I want to build a 33 as my first scratch build foam. Assuming that I can't find a friend with a band saw, what's the best way to cut the (2) 1" pink foam monoblocks? the number 11 x-acto blade doesn't seem to be the best, but may be.
How did you cut the block?

One of those electric meat carving knives with a reciprocating blade works pretty sell. If you can find one of those at a yard sale or second hand store that's a good way. I got mine new for $2.99 at a closeout store. It is wonderful for separating sheets of FFF from the bundle.

Another way is to try almost any of the various large (10" or so blade lengths) slicing and carving knives with serrated edges that have been sold over the years. The more jagged the edge the better it will cut. Use a sawing motion with light pressure more than trying to force the blade through the material.

I have a flat thin piece of wood (actually a cedar roofing shingle) with 60 grit and 100 grit open grit woodworking sandpaper glued on the front and back of it. I use that is smooth and flatten any roughness on cut edges. It is also perfect for taking the sharp right angle corners off of foam in almost any form or shape.

If you block the sanding shingle against something that is vertical and slide the monobloc against it it is perfect for squaring it off.
