The moderators here have refused to make the following thread a sticky thread, they seem to think that we Blu Baby 33/KFm wing/Tony65x55 aficianados are not deserving of that. So a couple of the regulars have gathered up the info and made a thread that contains just about every link anyone would ever want about those things:

** Tony65x55 ** planes and plans. - www.rcgroups.com/forums/showthread.php?t=997484

And post #5 in that thread has an list of a few of the power systems used on the BB 33, and as you read through the thread, you'll find other have posted the details of their power systems. :

Blu-Baby Motor/ESC/Prop Combos - www.rcgroups.com/forums/showthread.php?t=997484

Many of the newer builders here have not added the details of their power systems to that thread. If any of them should read this consider it a polite request to help the newbies here out by posting a brief list of their power system components for the various builds to that thread.

This is a quick and easy way to add it is a post with this info:

BB 33 (or whatever build it was) and wing type

Motor:
ESC:
Prop:

If you want to flesh it out you can include any or all of the following bits of info:

AUW at maiden:

Power System Details

Motor:
Kv:
Weight of motor:
Battery: (cell count and capacity)
Prop:
ESC:

Electronics

TX:
RX:
Servos:

And thanks in advance for the help if you do that!

Jim_W, where does your plane balance with the battery that far forward? If it balances in the right spot, you might want to check the incidence of your wing and your horizontal stab. Maybe one of those is a little out of wack making it fly funny and not being actually tail heavy. Just a thought. Looks good!

You could be right as it is difficult (for me) to get incidence spot on with my scratch building skillz!

It balances in the same place all my other BB's have CG'd, at the highest point of the airfoil or about 1/3rd the chord from the LE.

Also, I'm satisfied that this green foam wing is "shapeshifting" due to its lack of rigidity!

I'm gonna give it another flight or two if the weather ever cooperates again. I've cut another slot in the fuse for the battery and it's as close as I can get it regarding CG. If it still acts crazy I'll cut my losses and move along.

Thanks guys. The wing is KFM5a, Undercambered with fwd 40% double thickness. It has a 1/4" spar at the step on bottom, and another spar at the LE that is sanded to form the airfoil curves. I have heard several times that Undercambered wings don't like ailerons, but this guy handles the two features just fine.

Looks like your new BB is flying very nicely. Congratualtions on a successful flight!
Don't go hanging it up in one of those trees there though!

I built a 33" last night after finding some suitable 1/2" thick foam at Dollar Tree. The blue section is made up a 'kneeling pad' and the rest is plain DTF. I added a bamboo skewer spar just in case.

Looks like it has a chance to fly! What is the AUW and the power system?

About 7-8 Oz. without the battery, waiting for a new lipo to come in, hobbyking says they weigh 80 grams (under 3 oz) so probably 11-12 oz total.

Motor is a turnigy park 250, rated for 8 amps at 2s voltage, I'm guessing less than 50 watts without any measuring equipment and a 7x4 apc prop. Esc is a turnigy plush 10 amp. Battery will be a 1300 amp 2s zippy flight max.

Congrats on the successful build and maiden!

It looks like it was pretty windy and gusting as you flew, is that not so? From that long period of hovering as 2:00 to 2:30 or so, it looked like the flight speed was matched to the head wind. That gave a good long close up of it.

And I think you got away with a cross wind launch at the start too.

Congrats again!

Jack
