Official Black Horse 1724mm Dornier DO335 Pfeil ("Arrow") Thread

[MANFRED]

Will somebody please produce some 3d main gear doors to cover up the ugly strut? Thank you

For those considering the FlightLine Spitty 5055-390 motors. Test fitted mine a few minutes ago.

Mounting holes need to be drilled ~ 1/4” outboard of the existing 3mm holes. The length of the motor is just about perfect, to fit within the cowl. Maybe a small shim is needed, but not much of one.

What are you using for your battery setup?

Looks like the motors were made for the DO 335. My set was due today but still showing in transit, most likely will be here tomorrow. Thanks for the preview Oxotnik.

I've been eyeballing the EF one also but it is just tough to swallow that $90 cost
It would be really a huge win for the modelers if Motion/Xwave developed a RM400-105 for an affordable cost of like fifty beans

Yeah eflites are expensive. I have one from another project so it won't cost me extra to try it out. My biggest problem is too many projects at the same time.

[Oxotnik]

Received the XWave RM400-90 for the nose gear yesterday and now have the nose gear installed, including the NG steering. Getting the pull-pull cables the right length was a bit tedious as the NG Steering Servo is pretty far forward in the servo back and there's not a lot of room up there to fiddle with tensioning the cables. I'm glad that I have small hands. LOL

I did finally get the pull-pull cables tightened up and to reward myself, I dorked out my 335, by programming the gear to retract on different delays. Why? Because I could. I'm such a dork.

Hopefully, my motors will be delivered this evening.

And if anyone is thinking about hiring a full-body pilot to drive their 335, the 1/7 - 1/8 scale WarbirdPilots pilot will fit. The seat will have to be cut out to lower him so that the canopy will fit over his head. Openings will also have to be made under the instrument panel for his feet to reach the rudder pedals. Easily done.

Not a problem as I was planning on shimming anyways. AS far as the weight of the ship compared to the tigercat, do you have the tigercat? It is heavy! and tricycle gear generally do not take a lot of the landing stress on the nose gear... unless you land poorly. These are only $15.00 as well

I had the FL Tiger until the infamous garage inferno that claimed the majority of my fleet.
The Tiger weighed in about 9 lbs with 2 4S 4000 LiPo's and a couple mods to the airframe and gear
Yes, the $15 price of the FL/FW etracts have always been a more palatable price than the long standing FMS line or the much higher priced EF stuff.
But the short of it really comes down to the fact that these etracts all really need to be of more robust metal sided construction.
The days of the FMS etracts saw some salvation with the after market aluminum side plates made by Small Parts CNC whereas side plate fatigue and cracking was eliminated with etract longevity being greatly increased.
I can't distinguish the difference between them, but the FW A-10 nose gear(Type C) is basically the same as the Tigercat(Type E) however the Warthog weighed about 12 lbs.
With the Pfeil weighing in close to 15 lbs, the plastic case etract is gonna show it's problematic characteristics (cracked cases) real quick.
A bird of this weight and price really deserves an Xwave etract (what the others are proposing to use) or something similar to provide gear reliability.
That's is the reason for my subtle prod in the prior post for a RM400-105

Hate to be the bearer of this info but the Flight Line Tigercat nose retract is merely a 90 degree unit.
It looks like it is more based upon a side view of the nose gear but that is how the retract is mounted in the airframe with a forward up angle.
It is the same retract as the mains on the Tiger except for that the trunnion which accommodates the steerable nose strut which is e-clipped at the top of the trunnion versus set screwed in hard.
The nose retract is also used on the FW AL37, 90mm F/A-18 Hornet and 90mm F-4D Phantom.
If you look at those product pages you can see that the nose gear is straight down.
Sorry :neutral_face:

Yep, I checked out the parts and confirmed what you're saying :frown: It might also not be able to handle the extra weight of the DO 335. Still thinking of using the Eflite 105 degree NG

i'm going to try this:

bush the 3/8 hole w a wheel collar on top of the bushing to allow steering. but will most likely be flown first w nose gear locked down. we'll see once it gets here.

I ordered 2 of the Xwave retracts for the mains and the nose retract from the FW Tigercat, it has probably a 105* angle. My Do-335 should be here by tomorrow... by the way, wash your hands!

My Do 335 arrived today! I have to say the box is huge. Will open it tomorrow to check it out. Spitty motors are supposed to arrive tomorrow also. Great idea using the Tigercat NG for the DO 335, keep us up to date how it works out.

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.

[Oxotnik]

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.

Excellent. Thanks!! I love it when a problem becomes a non problem. I guess that I should’ve actually pulled the spinner off my FlightLine Spitty and taken a look before I bought the motors for my 335. Hopefully the Spitty motors will arrive this evening or tomorrow. I’m anxious to get the motors mounted and run the motors/props with a wattmeter. I’m expecting to really like the power of the Spitty 5055-390 and MAS 16x10x3 prop. My preference would’ve been to have a bit more kv, but the lower kv should pull less current, and thus give me a little more flight time, at the expense of a little power and speed.

[OV10]

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. :-)

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.

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.

Agreed. The gray plastic pieces need to be blended in, for sure.

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.
