There are Brushed and Brushless versions of what HH calls the "AR6400".

Dr. John's Mig 29 uses 2S Brushless equipment like what is found in the AS3X Mig 15.

For 1S planes, most people stick with Brushed, because it is more efficient, because of the gearing.

What UNGN said. This little 16" ws Jumping Bean sport/pattern ship uses the motor and Rx from a Stryker UMX. This is a 2 cell brushless non AS3X system. The X in UMX designates 2 cell brushless.

I launched the Jumping Bean right behind a 70mm F-16 this past weekend at a fly-in in Mullberry FL. I was able to pass him at will. When I went to see what his setup was he had packed up and left the field. I will admit it was not a very fast F-16 but the Bean will do 60 +.

And.... based on when I flew your prototype, it will fly really slow as well. I was doing inverted harriers at a crawl and was pretty darned impressed. It was almost like it was hanging from the ceiling on static display. I look forward to seeing how V2 performs. Should have time for video this weekend, weather permitting.

these are worth a look brushless with gearbox ...about 60gms thrust on a single cell

They would be great if they had a 1.5mm shaft instead of one of a 1mm one made of buttermetal.

I think 40gms thrust is more realistic also. If you can find just the motor this would be a perfect gearbox for it(direct fit), but you would have to ream the hole in the pinion gear to fit the motor.

Light Carbon Cub (1S set up)

After having crashed the CC that went crazy for a unknown reason, i decided to make a light version without AS3X, without flaps too, but with a pilot!
I made a removable wing with 2mm depron and struts are made from balsa.The transport box will be tiny!

Motor: 5g Mighty Midget brushless motor
2.5g ESC
5030 prop
AR6400
2.5g Servo for ailerons
1S 180 mA.h battery

AUW is 70g (20g less than the original CC).

Here are a few photos of my first custom built indoor plane, an Etrich Taube.

I have an outdoor one, 2m (80 inch) wingspan for RC and really like it so I thought I would try my hand at building one using my Ember 2 module and gearbox as the Ember was getting a little tatty.

I copied some 3 view drawings of the real plane to cut all the sheets out to get a good outline, and with a large RC model available I knew how it should look. The build is all depron sheet, 2mm for the wings and the flats ections of the fuselage. The curved turtle deck is 1mm depron, scored and rolled. UHU Por was used for assembly. The undercambered wings were created by warm beinding, the sheets were coverd with plan proctector and then taped down on the leading edges of one of my large RC models wings and then heated with the hot air gun. The reflex sections at the wing tips were then heated seperately. Colour is by Promarker felt pens which give a reasonable antique colouring. The wheels are commercial items, laser cut plywood. The undercarriage is self made from thin piano wire and is a simplification of the real thing. A bit of scale detail from light balsa for the engine block and radiators has been added along with waterslide transfers. The transfers were made by photographing my large RC model, messing about with Paint Shop Pro and then printing out the results onto the waterslide.

The most difficult part was getting the down thrust right to match the undercamber of the wings and I still have ended up with down elevator mixed in with increasing throttle to stop it climbing madly. It flies around really nicely on about half throttle.

Absolutely beautiful

Could you do a construction thread and/or post the plans. That is beautiful and I bet it is really beautiful just floating around.

I'll see if I can find the drawing I printed out to cut the sheets from and put that up along with some notes / sketches. As I made the design up as I went along there is no plan as such and I never took any pictures during the build.

I'm planning on building a twin engine plane with about a 26" wing span (I know, might be a bit big to be called a "Micro", but it is 1/24th scale); all 1/32" balsa (fuselage crutches will be 2 layers laminated 1/32) construction and fully sheeted in 1/32", retractable landing gear, and probably at least 200mah battery capacity. I'm guessing it will weight some where around 4-5 ounces, perhaps as much as 6.

Now, the props to scale would be about 6" in diameter and three blade; is that getting a little big for the mustang motors, and where can I get props that size and counter rotating?

If I have no choice but to use the mossy props, would they along with the mustang motors be able to haul a plane of this size?

Assuming the mustang motors won't do the job with 6" props, what about an AP05 brushless with the same props and a two cell power set up?

Thank you for the help in advance.

Are there any pics of how people set up the push rods on these micro planes?

Cheers
