Well this was a project about 4 months ago....lost interest, but after I converted the Estarter using the wings I decided to rebuild this one.

Its a little rough, because it had been built, crashed,built crashed, etc.

My main problem before was brushed motor controllers....just don't have any that were capable of handling the j-250s with DD props

anyway it was reborn this morning....with two 4100 kv motors setup for DD 4" props

elevator
and rudder

took it out and it will climb on 1/5 throttle! full throttle is insane and I actually blew one of the props apart :eek: thankfully it was on the ground

btw it flies nice, and I will put ailerons on it.

I'm currently working on a BP21 version
the inrunners on the original are overkill

The bp21 coupled with a 5" prop will produce enough thrust and draw low amps. This will allow a smaller lipo

I've been playing with prop sizes.
The 5" props work, but don't give a lot of "O S***" power out. I tried 8" props and it can take off straight up...waaaay too much
I need to get some 6"

I have one of those in its bag still. :o

I just may put a 2408-21 on its nose. :p

How did you mount your servos? :confused:

darkside212
06-09-2006, 06:35 PM
hot glued em'
using SG50's on rudder and ailerons
Sg90 on the elevator


its a great flyer and one BP21 on the nose would pull it around nicely.....but I gotta have a twin

Good idea. :D

BTW, the F/W motor mount that came with the extra motor, is that available through you separately? :confused:

I'll be getting me a few on the next order. Have quite a few planes here (7) that can use these motors F/W mounted. ;)

well I got the 6050 props today....put them on, and ran up the motors :) me likes! should haul pretty good.

I also got some 6030s if I don't "need all the power"

two bp21s

the 8040s were too big, and I didn't need all that power. One bp21 with an 8040 will power this plane nicely.

the 4100 inrunners setup for direct drive really hogged a lot of amps.....Even though my EP20c 2200 pack handles it fine, I would prefer a setup that can utilize all my packs (large and small). My 1300 handled the 5" props fine, and I'm sure it can handle this setup as well.

darkside212
06-11-2006, 03:46 PM
Well I test flew it this morning. Flies nice on the 6050s! plenty of power. It was a little windy but it will climb on 1/3 throttle!

I'll do so once I am finished with it. :D

Cutting, digging and carving foam and cameras don't go togheter quite well. I almost pushed one of my two cameras off the workbench while moving the Airfoilz YAK-54 around. :eek:

Close call that was! :o

BTW, I found the ideal model for the BP21 motor on RCG. It's a two year old BLUCOR design called the "FAT BEECH" as in Beechcraft, so don't anyone get ideas about reporting me for getting near the foul language line on my posts. It's a cartoon version of the Staggerwing Beech. :D

It's one of those models that one can't help but like Paul. Ernst, a friend in Bavaria sent me photos of his this morning. It looks hilarious, so I asked him where he'd gotten the idea. He put me on to RCG where I found the plans and pics. :D

Putting my airliner aside for this one. The thread is from June 2004, but still active. When I saw this little thing (28" wingspan) I knew I had to build one. All I have to do now is get me some more BLUCOR. :D

ahhh another infamous gene bond plane.....Gene Bond did the Flat Beech. :)

DPW did the FAT BEECH. Two different models. The FAT BEECH (undercambered airfoil) flies really good, the Flat Beech (flat plate airfoil) is a bit quirky as per his own (GB) impressions further down the thread. :D

Did you see the photos of it in flight? It looks comical! :D

darkside212
06-12-2006, 05:29 AM
any way...I broke one of the 6050s and put the 5" back on...When I originally flew it with these props it was really windy, and I guess the wind inhibited my perception of the flight characteristics. It flies nicely with the 5" and I even did a pathetic loop. :)

The ailerons really don't do much. The rudder is a lot more effective in controlling the banking and turning!

I might use the ailerons as flaps....just for kicks

darkside212
06-15-2006, 04:14 AM
I setup flaperon mix allowing me to utilize the ailerons as flaps. It is very easy to setup on my futaba 9CAP.

I went out and flew it using flaps....flies great! the flaps do a lot! I don't need them, but it sure is fun!

its comming along

I made the nacelles a few days ago out of blucore and have been painting them. I ordered some replacement edf55 housings and rotors. I was disappointed because the rotors did not come with the hub to secure them to the motor.

I just attached them a few minutes ago

darkside212
06-20-2006, 11:59 PM
If you look at the tail you will notice I have a layer of blucor under the original horizontal stabilizer. I also put a CF rod in between the layers for support.

Those two EDF units look kool side by side. You have come up with something rather unique in the DIY area of this hobby! :)

It is really easy to do all you need is a jelly jar and a hot glue gun :)
the a10 scratch build uses a similar design

I'm still working on the elevator....not sure what to do

either split surfaces, or one


one would be easy, but might not look good

two is a little harder to do, but would look a lot better

06-21-2006, 02:19 AM
I went with one surface:

I went with one surface:It looks good, but will two hinges so close to each other be enough support for the entire elevator? :confused:

I put a cf rod on the other side....solid as a rock! :)

I just got back from the maiden.......:D

winds were 10+ but I couldn't help myself

it flies great!!!!!!! full throttle is not necessary only for take off

it will fly/climb at about 1/3 throttle


I actually like it better than the bp21 version :D

but will need to put flaperons on it
of course I will be painting as well

Unfortunately I crashed the EDF version, but I got some good info from it....I took the aileron idea and the T tail and put it on the twinBP21 version. I put the fluke on the bp21s and got a whopping 9amp draw using the 5" props :D
