I have been waiting for this bird.....even got the Cessna O2 to play with the push/pull thing...…..wasn't expecting it NOW. I am not really in a position to get yet another 400 buck bird, that is a grand by the time it is airborne.....but I love it Even got a Revell 1/48 model as a mule.
7 left.....that IS what credit is for I suppose....my wife wants to buy it for me as early xmas…..bless her heart. Have yet to fly my HE111 ! only 7.....will t6hey get a second batch pretty soon? What to do what to do....damn..... **she just got a 4 grand bonus....but that is hers....I feel bad taking any of it....I am retired.
7 left...…..coin flip? hahahahahahahahaha

So why are you not considering the recommended 17" more scale diameter prop?. Price of the recommended power system.?
The powerplant that I used on my 93" ASM A-26 was the FL 5055-390kV from the Spitfire using MAS 16x10x3 CW/CCW props.
eCalc spec'd out the mixed flight time @ 7 min using 2 4000 6S. They developed almost 3000W of power combined.
This looks to be my approach for the Pfeil.
The price tag for the FL motor @ $60 is a lot more palatable than the recommended Admiral @ $130

WC,
I’d failed to write down all of my thoughts. I’m am thinking 16x9x3 or 16x10x3. Might even try a 17” 3-blader, to see how what that power draw is. The SK3 5055-430 and14x8x3 only pulls about 60A, static; so, the 5055 is definitely capable of swinging a bigger prop.

I checked HK last night, and the SK 5055s are out of stock, of course. The recommended Admiral motor seems huge. I think that I want to stay in the Power 60 region. I did see a couple FMS motors that looked interesting. I could go with EFlite or Rimfire Power 60s, but I like the price point of the SK3 5055 better.

I’m very interested in some more details about your ASM A-26 and its power train. If it’s okay, I’ll PM you, to keep from going too far off topic this early in the thread.

I think that I'm going to go with Aerodrive SK3 5055-480kv motors (which are roughly Power 60 size). I'm running these motors, with MAS 14x8x3 props, in my 91" Phoenix A-26 and love it. In a plane that weighs about 1/3 less, I bet that they'd give the Pfeil a real kick in the pants. The 335 is supposed to be a speed demon after all. :-)

I'm not sure if there'll be enough room to hold two 6Sx5AH batteries though.

Don't think u will fit 2 x 6s 5000 in the front , u might be able to get 2 x 5s 5000 ….. I ran 1 x 6s5000 and it gave about a 4 min flight.... believe it or not theirs's not a lot of room in the front for the batteries and the hatch further back is where the servos also thats where i put the 2nd ESC..

Motors I used were sk3 5045 500kv with a apc props 14 x 7 front and 14 x 8.5 rear.

Also if u open up the scoop under the fuselage be prepared to get grass around the rear motor :) hehehe

reg the number on the tail, in my opinion font is too big and would of preferred it wasn't there..

[Oxotnik]

It does indeed require two motors. Something in the .46 to .60 equiv range should be good. Haven't fully decided on my choices yet.

I don't know how many DO-335s Motion brought in but they are going fast. Website is showing only 7 left. As much as I want one my finances right now can't justify another plane. :disappointed:

[CF-105]

I had a feeling it was a copy/paste fail ;)

[Twowingtj]

The packages and specs seem to only list one motor? Does this model not use 2 motors?

Thanks for the catch folks...These new product are always shifting in specs/data initially. Especially when we launch several new product at once. Some of these are simple "cut and paste" casualties that get carried into other product pages by accident. Nature of the beast sometimes. Thank you for your vigilance!

Oh, you can definitley count on us to find ANY inaccuracies. We're special that way... LOL

Good catch on the scale. Even without crunching the numbers... most single engine fighters at 1/5 scale are in the ballpark of 90” wingspan.

Regardless, it doesn’t change the fact that it’s a nice looking model that I’ve seen lots of people clamoring for, for a long time. I’m curious to see how fast they sell out!

Agreed. I'm not complaining. I was just scratching my head a bit, wondering if I'd screwed up the elementary math in some way.

Based on the provided wing area and estimated AUW, I also swagged out the following:
Wing Loading: 32.7 oz/ft^2 (which is very close to the 97.72 g/dm^2 on the product page)
Wing Cube Loading: 11.2

I'm actually pleasantly surprised by the WCL. I'd expected it to be a good bit higher.

What is the quandary with that number

My curiosity is peeked, too. My quandary is that the tail isn't marked with a swastika. Callie to the rescue (actually, I already have a sheet of swastikas of various sizes that I had Callie do for me a year or so ago, since hardly any Luftwaffe airplanes come with proper tail insignia). I know why they don't, but I then have to add them back on, for scale accuracy.

[Oxotnik]

I'm struggling with the scale math. The product page says that this model is approximately 1/5 scale (quoted below).




Full scale wingspan (per wikipedia) is 45.4'.
Model wing span is 1724mm.

Scale = (model wing span)/ (fullscale wingspan) = [1724mm/(25.4mm/in)/(12in/ft)] / (45.4 ft) = (5.66 ft)/(45.4 ft) = .1251, which is approximate 1/8 scale.

Where does the 1/5 scale come from? Am I ciphering incorrectly?

[OV10]

Shame that they left the number 163 on the tail still , would be far nicer without it
