Default Micro Beech Baron project

Hello there! Making my first appearance on RCU.

I was planning on doing (after some others) a new project - a 1/24th scale, 17.5" WS UM Beech Baron. I have most of the details worked out, I was just woudering if they would work.

I will be building a plane from these plans:





I was going to scale it down from 53 to 44 cm, use these motors:
www.hobbyking.com/hobbyking/store/__7230__hexTronik_2_gram_Brushless_Outrunner_7700k v.html

possibly an AS3X UMX beast brick, Hobbyking servos
www.hobbyking.com/hobbyking/store/__17540__HK_5320_Ultra_Micro_Digital_Servo_1_7g_0_ 05sec_0_075kg.html

I want to make this plane a 6ch, with flaps and retracts, plans of which can be had from Rcgroups.com.



Your input is much appreciated.
Thanks,
JSS4

I will use a UMX MiG brick when it arrives,
Just noticed Spektrum is out with UM servos. I would trust them better than HK:
Servos

Any guidance is appreciated.

I would suggest using a mosquito brick instead of the mig. While it uses brushed motors and dosen't have as3x, it has dual ESCs and the mig brick dosen't. Another option would be to use a hobbyking micro orange rx and two separate ESCs to go along with your motors of choice. However, It is hobbyking and you would have to use hobbyking servos, becuase the reciever requires servos with a special connector that nobody else makes to my knoledge. Personaly, I would recomend the hobbyking setup because you can use the motors that you already picked. And even if you found a way to connect two motors to the mic reciever, they would have to be the eflite brushless ones instead of your hobbyking ones.

Just my 2 cents

Why would the motors have to be Eflite motors? Is it some kind of binding protocol or something? Or is it something to do with the amp draws? I checked and the motors draw 1.5 A while the MiG brick can handle 6. Also the props I'd use are too small for the HH motors, but just the right size for the hextronik motors. Also the Parkzone motors are 8-9 grm ea while the Hextronik motors are 2 grm ea. Also what I'm after is a 6ch Rx instead of a 4ch.

Props: http://www.cermark.com/products/EMP-...-3x2-prop.html
These props are also just the right size for 24th scale whereas the PZ props aren't.

My mind is running circles on this. A wiring diagram or illustrated advice, or ANYTHING you can offer would be much appreciated.

If you can wait a bit, I'm thinking there's a really good chance that at some point, HH will probably release an AS3X UMX brushless twin, it's almost inevitable. I know that sounds hard to do, but it would probably be worth the wait! You could still build the plane in the meanwhile...

I'm still waiting on my UMX AS3X ICON A5. I am hoping they do a UMX twin, so I can get the guts and build this one because I am shooting for flaps & retracts. The best HH has done is flaps on a UMX.

OK I've almost finished the retracts, I was wondering if I could wire the motors in parallel or if I could attach Direct Drive 3 x 2 props to UM mossie motors to save weight. I might go AR6400T, but I still want to know if the AS3X brick would work on twin 1.5A BL motors. I'll post photos later.

cabin is in progress, and right wing is almost done. Retracts are proving to be a pain. Can I use servos other than the high performance servos for the retracts?

You know, Im pretty sure that spectrum make a 6 channel micro reciever simmilar to the hobbyking one. You would probably want that instead of the umx bricks.

http://www.spektrumrc.com/Products/D...odID=SPMAR6310 this is it.
You would have to put the ESCs on a y harness but it would work.

Thanks Waffleman. I got my AR6400 back from my buddy and I was thinking of  using that in external ESC mode. That way I don't have to worry about the battery(?) or overloading one ESC. The tail is almost complete as are the nacelles. Next up is ordering the ESCs and the motors, etc. from HK and buying other stuff from my LHS. It's coming along nicely.

Here's more. I redesigned the nacelles and the mounting system. More on that when it is completed.

Thanks Waffleman! I have just started skinning the fuse, and it weighted in at ~23 grams with half the tail covered. I'll post pics later.

Sweet... I just started building a guillows bf-109 which will use my old corsair brick. I might not use an electric motor though. The plans say it is posible to mount a cox .020 for tether flying. It will be the smallest glow plane at my flying club

I will resume the plane later because I am still waiting on parts.
