2028 FAI F4 WSC Planning Now?

Mon, 20 Jul 2026 12:42:39 -0600

City of Ostrów Wielkopolski... trading heat for milder(50~60 F) but breezy (18~24 mph) July conditions. The US Team Trial will be held in summer 2027 @ NATs

Exact physical location in Ostrów Wielkopolski has yet to be determined.

What’s your BUSA 1/4 Dr.1 weigh?

Mon, 20 Jul 2026 10:41:01 -0600

I have recently completed a BUSA ¼ Dr.1 and the maiden flight was successful. Back in the shop, I finally got around to weighing it and am surprised to get 19.0 lbs. I am not surprised to be above the box weight of 13 to 15 lbs but didn’t expect this much above.

The finish is Coverite Super-Shrink painted with Behr latex. I rolled on a single coat of the base yellow then dry-brushed the streaky green top coat. I replaced the stock landing gear with the Scott Annis aftermarket kit with bungee cord suspension. Engine is GP-38.

I am interested in what weights others are getting for this kit.

Thanks,

Rick

Heritage Wings RC - Canopies available

Mon, 20 Jul 2026 08:51:55 -0600

Just to ensure that everyone who has been waiting for a canopy is aware. Canopies are now available for all plan sets with the exception of the T-28 and the Wyvern. The T-28 will be available within the next month. I just need to do a bit of work to that plug first. I did not receive a Wyvern plug so I will have to create one.

These items are now listed on the Heritage Wings RC website.

If you have any questions about this or anything for that matter, just reach out to me either via PM or email at heritagewingsrcinfo@gmail.com

Engine for 1/2 scale Sopwith Pup

Fri, 17 Jul 2026 12:34:10 -0600

Folks, I have the opportunity to purchase a 1/2 scale Sopwith Pup weighing at a bit over 100lbs.

It has a 3W240 engine in it, but was wondering if a Fiala 250 radial would fly it or even a Fiala 215 twin. Four stroke.

Thank you for any help and opinions on this.

Trailer Ventilation

Thu, 16 Jul 2026 14:21:35 -0600

I have 6x12 v-nose cargo trailer I keep my planes in for storage and taking to the field.

Problem I am running into is the heat buildup inside the trailer in the summer; I have been researching an exhaust fan that is solar powered and has a thermostat on it for auto operation when it gets warm enough to kick on and run.

My search has led me to attic fans, and they seem to be the answer for what I want to do but I wanted to know if anyone on here has done something like this for their trailer.

Rare Laird Super Solution Large-Scale RC

Thu, 16 Jul 2026 13:44:46 -0600

Offering a rare large-scale Laird Super Solution RC airplane kit that's been stored since new and has never been started. I believe this is a circa 2011 Jack Divine Models kit.

The kit is complete and new in the original box, including:

Fiberglass fuselage

Fiberglass cowl

Fiberglass wheel pants

Complete hardware package

Decals

Balsa-over-foam-core wings

Built-up ailerons

Built-up horizontal stabilizer

Elevator

Rudder

The flying surfaces are professionally built from balsa over foam cores, while the model still requires final assembly, covering/painting, installation of radio equipment, engine, and finishing.

This is a hard-to-find kit and would make an excellent project for someone looking for a unique large-scale aerobatic/classic racer.

Condition: New, never started, complete in box.

Price: $550

Willing to ship at the buyer's expense, and I'll package it carefully for safe delivery. Local pickup is also welcome.

Thanks

Chris

Messerchmitt Me.163 "Komet"

Thu, 16 Jul 2026 10:06:56 -0600

I have been fascinated by the Me. 163 ever since I discovered it many, many moons ago, over the years I purchased several plans and even a kit made by Joe Saita.

About a month ago, one of these was offered for sale on RCGroups for a very attractive asking price:

https://www.aeroscale.shop/collections/airplane-kits/product s/messerschmitt-me163b-1-3-5-2-75m

The kit was offered by a well known local fellow modeler who put it for sale on behalf of Goetz Vogelsang. I bought the kit and picked it up. When back home I inventoried the box's content and found out that all the nice prefabricated fiberglass parts were in there including some "extras", however: the wood formers for the fuselage were missing.

It became clear that the box was opened, parts taken out and as I know that there were at least 3 kits: if and when parts were put back in their boxes some were misplaced.

It took another 2 weeks to finally get the missing wood parts and when I finally got them, I could not tell what belonged where because there was no bill of materials, plans, nor building instruction. The only "manual" was a somewhat fuzzy online "manual" comprised of fairly poor quality pictures.

I did not plan on building this airplane now but since it became obvious that should I find issues later on, there may be no one to talk to, and, given that it so hot that I cannot work in my shop or my garage, I decided to build the model indoors at least to a point where I know for sure that I got all the parts.

There is a ton of challenging information I would love to share but before I do so, I want to see if there is enough interest.

Please let me know.

FINAL 2026 FAI F4 World Scale Championship Results

Understanding "K" Factored FAI Scoring

Wed, 15 Jul 2026 21:40:56 -0600

Judging precision scale building is difficult to differentiate with a simple 0~10 point judging tool. FAI utilizes a point multiplier to further express either deficit or enhancement of a model's physical attribute by the modeler's craftsmanship/creative skill. This is utilized in both Static and in Flight Judging.

These finer points of reviewing a competitor's skill often determine a winner from an otherwise placement in Contest Final Results. K factoring tends to reduce probabilities of tied scorings.
