What is the relationship between these two organizations? Do they coordinate on national scale events?

Does anyone know where to get a replacement wing for these? Can be new or used. Maybe someone that can cut the cores? Any help would be appreciated. Thank you.

US Scale Masters in Hemet, CA

Mon, 26 Oct 2026 10:25:23 -0600

Here are a few photos from the U.S Scale Masters Championships 2026 that took place last weekend at the Hemet Model Masters field in Hemet, CA.

Just sort of odds and ends photos with a few random flying shots. I don't have the gear for great flying shots.

lozenge printing

Mon, 26 Oct 2026 07:49:12 -0600

Having read the topic on Scalecover and Oratex lozenge patterns, I noticed the topic is now closed.

What I would like to ask - those that know, what is the best printer/scanner ink to use on Scalecover or any other heat shrink covering to produce a lozenge pattern that will withstand the weather/temperatures of our hobby and would also accept a fuel proofer such as Klasskote.

Thanks

For Those in Search of a New Project #407

Sun, 25 Oct 2026 21:27:44 -0600

The Heath Center Wing CNA-40, developed from earlier mid-wing racing aircraft, was popular with those able to fly one. The aircraft was also available in simplified kit form pioneered by Heath. Unfortunately 1933 was the depths of the US Depression and only about six aircraft were built (plus an unknown number of kits).

On board air compressor?

Sun, 25 Oct 2026 06:43:12 -0600

Greeting to all fellow scalebuilders,

I am building a Jet Provost, at 90" span, scaled up from a smaller edf. It will be my first turbine. The rather large, boxy fuselage space is being gobbled up by the need for at least 3 litre of fuel, preferably more and the space that I had intended to hold a large air resevoir has disappeared.

I have three large scale retract units plus air brakes to feed with air at around 100psi and even ganging conventional size air tanks together, I don't think that I have enough air in reserve.

You can now buy really small, self contained air compressors at decent prices, most can be set to cut off when a certain pressure is reached, but generally, they need a button to be manually pressed to start the fill.

Is there anyone out there who has experimented with something like this to provide an in flight, air top up if needed??

I know that air retracts are yesterdays news but I have used them reliably in aircraft for a long time without too much hassle if certain rules are followed, one of which is to have a decent sized (large) air tank, often home made from an aerosol can.

Any thoughts or suggestions would be appreciated.

More from Less?

This tandem Mistel flight is impressive for several reasons.

https://www.youtube.com/watch?v=GD6MzOwfTYA

First there is the flawless build execution and nice scale-like flight choreography.

If you read the description this might catch your eye:

DFS 230 (Glider):

Wingspan: 4.4 m / 14.5 feet

Length: 2.3 m / 90.5 "

Weight: 8.5 kg / 18.7 pounds

Klemm 35-B

Wingspan: 2.08 m / 81.9"

Weight: 4.2 kg / 9.3 pounds

Engine: Saito FG-17

Thats a combined 6.5 meters wingspan / 13 kg all flown with just a 17cc gas engine. That's 1 cubic inch displacement.

It does look like its flying on the wing and its clear that the pilot(s) understand proper energy management in flight.

I was worried that my 3 meter, < 10 kg biplane project could not be powered by 20 cc nitro and instead opted for a 30 cc gas engine.

I'm sure its a good choice from a safety & redundancy perspective.

But this video shows me that perhaps its also a question of skill.

1/9 Yke Rusticus Lancaster molds plugs

Sat, 24 Oct 2026 13:50:45 -0600

Been awhile since I posted on here. Ending my mold making career. What better way than to make the Lanc molds and plugs. Made the cowl, upper engine nacelle, inner and outer lower engine nacelle molds. Made plugs for Main canopy, front nose,front turret,middle turret and rear turret. Got back a little while ago from Keith Sparks house. He pulled all the canopy,front nose and turrets. All those have the frames molded in. Engine cowl and nacelles have panel line and details in the molds. I have breathing problems from copd so reluctantly I am going to put the molds,plugs and parts I made up for sale. As soon as I figure out how to upload pics I will

Robart TFGS Fw-190A trunion houseing

Fri, 23 Oct 2026 22:40:31 -0600

Hi everyone, a friend of mine has a TFGS fw-190 for sale thinking about buying it. But it has the robart fw-190 77degree retracts.

What I would like to know is is There anyone besides robart who has made these trunion housing or where to get some.

If I get it I want to do the double trunion housing mod cause they are electric gear. E-mailed robart nothing , e-mailed highvis Rc , nothing, and e-mailed Darrell at serria to see if he ever made them like the p-51’s he’s made and nothing. So any thoughts any one have a spare set.

And the other thing , Does anyone have a copy of the wing ribs and mounting plate to fit a set of serria 1/5 fw-190 to the top flite gs fw-190 wing I have a set for a kit I have , if I feel like using them.

And JGrc, what exactly do I ask Darrel to get a set of the new angle trunions that you got made for your fw-190 gear.

Thanks Joe

I know RCSB is mostly large scale planes, but I heard that there is a sub-forum for small scale planes, which is what I'm interested in: mostly hand launched, roughly 1 meter wingspan or smaller planes, like the so called 1/12th scale planes. I'd appreciate tips to finding these guys.

Additive Manufacturing - 3d Metal Printin

Thu, 20 Oct 2026 11:49:59 -0600

A new technology (for me) and i'm curious of its application to our hobby. There are many accessories slowly getting more difficult to obtain (unique mufflers, struts, landing gear, ect) and I'm curious if its something usable for us (matters of strength and cost vs machined aluminum). My specific frustration stems from a project I started on with the confidence the landing gear was being made in the background. Well I've reached the point in my build, that I cannot go any further. The project is a Romanian IAR-80 in 1/4 scale. Nothing too crazy with the landing gear other than has a dual fork that holds a 6" tire (very similar to the Macchi 202). I'm practically at the point where I'm considering using the Electron Uppers and having a strut made. The Aluminum Components (upper strut, scissor links, fork) would be metal 3D printed and the lower strut and springs commercially bought SS. A friend of mine is drawing up the design in 3D now. There are many places popping up where you can send the .stp file and they will print in a variety of materials. I am just unfamiliar with the 3axis printing, is there a weak spot vs machining from 6061-T6. Opinions?
