Title: Blue Baby - Scratch Build
Post by: atul_pg on February 17, 2010, 10:42:06 PM
A friend of mine suggested me to build Blue-Baby as my first scratch build. :) So here we go...

I got the tiled plan from rc-groups and as of now just printed them out & cut them by scissors..

Tomorrow will lay these paper cut outs on the foam and do a surgery..

Using a 5mm sheet for the entire build..any suggestions ?

Check out the pic....

use 2mm coro for wing as entire structure with 5mm will be quiet heavy as my experience says.

Going with a powerful enough power system would also work, right ? :headscratch:

Am using a rcforall 2212/13 motor , 9gm servos, 30 amp esc and I guess will go in for 1800 mah..

Sandeep It wont be heavy..one of the guys on our field has made a 3D plane completely out of 8mm and he uses this motor... So no worries..

Surgery in the night or evening..

cheers..

Hey Atul, the wing is depron and the fuse is coro right?


Title: Re: Blue Baby - Scratch Build
Post by: atul_pg on October 31, 2010, 01:44:06 PM

Nice to see it in the air :thumbsup:

Looks like you have to reduce your throws, or add a good amount of expo.


Title: Re: Blue Baby - Scratch Build
Post by: atul_pg on November 22, 2010, 03:12:48 PM
Bang on anwar..The throws were too much..prady helped me reduced the throws by using the dual rates..

Infact was just checking this link..

Hey guys. I am planning to make a blue baby 42 inch model  :P and as per the plan I should use blue or pink foam for monobloc. And wing should be Kfm3 with dihedral. I have folllowing questions. Please help  :banghead: :banghead:.
1. Can I make a Kfm3 without dihedral? Not very comfortable with dihedral ;D.
2.  Will Kfm2 wing work? 8-)
3. Can I use normal foam (one used for packaging) for monobloc  :P?
4. Styrofoam which is 1 inch thick can be used for making fuselage/wing 8-) 8-).


Title: Re: Blue Baby - Scratch Build
Post by: dineshk13 on April 30, 2011, 10:38:54 AM
bump. Basically my doubt is styrofoam of 1 inch thickness can be used for what purposes. common guys.


Title: Re: Blue Baby - Scratch Build
Post by: KALYANPRODHAN on April 30, 2011, 10:44:10 AM
Dinesh, Use hot wire cutter and you can get the desired thickness foam sheets as you want.


Title: Re: Blue Baby - Scratch Build
Post by: bokilap on April 30, 2011, 10:51:28 AM
Use 5mm thickness biofoam (depron) for fuse and wings.
I made monobloc using 1 inch thick regular thermacol. However you need to make it tougher using fiber reinforced tape.It gains good strength with it.
Use fiber tape on leading edges as well as trailing edges.

Hope this helps.

Go for 3S battery and your blue baby can do acrobatics.
I have used 1000mAh 3S battery with 10A ESC, 2204 motor and 7x6 prop. 7x3.5 would be better. But with 7x6 prop, I have to limit throttle upto 60%.
My Coro 24" WS plane AUW is 270 gm.
