ok so I don't know if I would trust the stock spinners, the front is an elliptical and the back is a std. I have one of the spinners from the place I posted for a 2 blade prop, have not flown it yet. if I have time i'll see which one fits.Platt: fw190d9 Dynaflite:PT-19 IMP:Macchi202 ESM:fw190 ESM:Tank, Hien Jackson:DH-2 BH:macchi200 Extr:fw190 Holman:me109F H9spit2 FL:F4u,spit 9 FW:me262 GP:us60, Stuka, cub, F4u PZ:me109, albi EF Hurri, T-28 FMS: 2x fw190, me109 Lone Star:Skat Kat RSCombat:2xfw190d9

For all of you who are living vicariously through my Pfeil exploits, here's my nightly update.
All servos/pushrods/control horns have been installed loosely, awaiting the first power-on of the control system. Main retracts have been installed using XWave RM400-90 retract units. I'm still waiting on my retracts for the nose gear and pull-pull system installation. Also, waiting on 5055-390kv motors (FlightLine Spitty). There have been absolutely no bad surprises during the build so far. The H Stabs went on nice and straight and the wings also slid right into place for a good, snug fit. While I wait another day or two for the front retract trunion and the motors to arrive, I'll start programming the 335 into my JumperTX. I'll be using two FrSky X8Rs to have 16 channels available, although I won't need that many. I'll also start installing the vacuum-formed plastic trim pieces.
The only thing that I've seen so far that I wish had been done differently is that the dorsal and ventral rudders are mechanically Y-d together and the left and right elevators are also mechanically Y'd together. I'd have preferred that all four have had their own servo, so that I can subtrim them with the radio. There aren't accommodations for two extra standard servos, but I may look into adding a another PW tray within the Servo Bay, to add two additional servos. I mounted my pushrod connectors a bit differently than the instructions, but we all do pushrods and connectors our own way. Six, one half dozen, or the other....
Oh, one other thing that I did a little differently... The instructions said to epoxy the plastic wheel wells in place. I, instead, chose to use five #2 sheet metal screws to mount each wheel well in the wing. That way, I can easily take them out, if I need to get inside the wing for wires or something..

The aft spinner is more conical. Here are a few pics of the full scale at the Hazy-Udvar museum from last fall.
The Naval Aviation Museum (Pensacola) is different, in that nearly all of the planes are fully accessible. You can walk up to, crawl under, whatever. I enjoyed getting a lot of details shots of their two-seat ME-262.
I was looking at some photos of a Do-335 under construction -- turns out they did the fuselage much like the ME-262, in that all panel lines were puttied and sanded smooth! So really, the only lines should be removable panels. Nah, I'm not going to repaint the plane!

Did my first power-on today. No smoke, no fire, no shorted servos. Well, I did smoke the landing light LED. I guess that it wasn’t rated for 8.4v. The LED ran for about 10 seconds, then died. Oh well, we’ll just constrain ourselves to fly during the day. In hindsight, I should’ve mounted the landing light cover with #2 screws, instead of epoxy. If I have to open up the wing again, I may replace the landing LED.
Installed the plastic trim pieces. All of the trim pieces fit nicely and were easy very to CA in place. I trimmed the aft exhaust stack quite a bit and it looks a lot better than the untrimmed piece would’ve looked.
Doing some mechanical aligning/trimming, while I wait for the motors to arrive. I’m still thinking about ways to mount 2 more servos, for the elevator and rudder.---

Oh well Guess the booze patrol is gonna have to monitor your build consumption You can pretty much bet that all "standard" RC LED's are maxed out @ 5V---

The rimmed down exhaust looks much better. Looks like weathering the vacu-formed add on bits will need a bit of weathering to blend in.
I was surprised at the difference in presentation character the plane has when in the sun vs. in the shade. In the shade, it looks almost over weathered. In the sun, it really nice.

The aft exhaust stack, I moved upward so that it'd fit between the balkenkreuz. The exhaust weathering is a bit lower though. I may have to get my airbrush after it, too.

Looking good, without a doubt the exhaust looks better trimmed down. That's a must do for me also, stock is out of proportion.I'm hoping the Spitty motors work as I already placed the order at Motion.

You and me, both. We're committed. My only concern will be getting the MAS prop to work with the hex on back end of the prop adapter. It should be easy to engineer a solution, though, even if it means filing/grinding down the corners of the hex., or, maybe, using a Forstner bit to open up the end of the prop through-hole enough for the prop to seat around the hex. I guess that a hard plastic shim is another option. There are multiple ways to skin this cat. :-)

The Spitty's prop shaft adapter has no hex to worry about. That was a bonus reason I selected the motor set up when I told ya about using it with the MAS prop on the AMS A-26.

A couple other blending-in tips...
The G-10 control horns are ugly. I hit mine with a wide tipped black Sharpie, and the black control horns almost disappear from sight.
The inside of the of the FG cowls are very light colored. I painted the inside with acrylic flat black, severely diluted. Diluted black quickly dulls the inside of the cowl, without adding much mass at all. The interior paint doesn’t have to be consistent or pretty, just dark, and will black out the inside of the cowls when they’re installed on the plane.---
