Brilliant!!!

With all due deference, cutting back the foam allowed for a longer bell which in turn allowed for a smaller opening for the electric motor.

For my build, this also allowed the first cylinder row to set back closer to scale location aft of the cowl ring.

I compensated for the motor thrust line offsets and the tighter tolerance at the motor by angling that portion of the print to match the thrust line offsets and prop adapter.

Different strokes for different folks.
I love the idea of the photo for back row of cylinders which have saved me about 1/4" of foam surgery.

Again, really nice work gentlemen; you guys are awesome.

When Dave sent me those pics, taken at our field last week, I just sat and stared. It looked so real!
The original bellhousing is really long and in order to get it to fit over the motor with enough clearance and to meet the maximum length of the overall project ( which was around 2.5"), we had to leave a fair amount of the front of the motor open, what we gained for the sacrifice in looks was the amount of air cooling flowing across the electric motor, a good trade off.
Here's a shot of the bellhousing with the front row of cylinders glued on:

Then, I washed the cylinders down with black and placed it onto the photo of the back cylinders.

I used some elastic thread, the kind you find on greeting cards, for the spark plug wires, unfortunately for me, I had to use two different kinds, they were different shades of gold so I decided to go black and be a little different than Dave's. BTW, I designed the ring that the wires come off of.
this is what the rear cylinders look like:

I just printed it off on photo paper in black and white and it worked quite well. A lot easier than trying to get a proper picture.
Here's one of the concepts we tried using the 1/8th" thick rear cylinders:

And these are after removing the original motor from the cowling and trial fitting the new motor:

This is Dave's finished product, all ready for final installation:


This project was so much fun, goes to show you what can be done with this new technology!

Yes absolutely incredible rendition of the r2800

Even without 'hacking foam' it is a thing of beauty.

Bravo Zulu to each of you.

Fantastic Dangerous!

[Aros]

Wow! Simply beautiful!!

[Grossman56]

So, here it is guys, the new and improved R 2800s, after a lot of redesigning, refitting and playing around around with shapes and numbers, we finally came up with a pretty good design.

Better than the stock one!
I bought the STL file for the R2800 but it was too large to fit straight in.
The original has the bellhousing and the rear cylinders all in one piece, I ended up modifying that by slicing off the rear cylinders and shrinking the remaining part to the correct diameter, then altering the height to fit. This meant recreating the circular base that the mags sit on, which wasn't hard and then trimming the nose of the bellhousing for the angle(s) of the motor. Once that was done, I handed it over to Dave to work his magic on the printer and he came up with a great set of parts. The rear cylinders ended up being a picture blown up to size. On mine, I resized the rear cylinder part using Tinker Cad and printed a picture of that in black and white on photo paper, came out great! I did try 'squashing' the part in Tinker Cad so that it was 1/8" thick, but there just wasn't enough room without hacking foam, wasn't worth it.
Have to get mine out in the sun next weekend, it's supposed to be in the 80's, right now we're clouded over and had a bit of snow. Wyoming has five seasons, this being 'Sprinter'
where we can go from the 70's to snow in a day, sucks, but it's worth it to live here!
Anyway, got our creative juices flowing!!

Welcome to Hobby Squawk.

Great question, if it were me, I'd take a couple pics or a short video and contact Motion RC Customer Service.

The plane is new, right? I'd check with those guys first.

Glad to have you onboard.

Hi. I solved it by buying a replacement elevator because of the shipping cost. I will fix the original one later when I know what it looks like inside the hinge. I have flown it three times, it flies great and lands as easily as a Jumbo Jet.

[Grossman56]

Ewww, stand by folks, there's something cooking in Dave and Dan's hangar

Hi. I have a new Corsair and while assembling the model I discovered that the elevator has a lot of play in the hinges on one side. The play in the hinge makes a big deflection at the end of the wing, about 3-4mm. Does anyone know what the hinges look like inside, their shape and principle? I don't want to use a lot of force to take it apart and see what it looks like inside.

Welcome to Hobby Squawk, glad to have you onboard.

Go back to the webpage at Motion RC and 'click' the "Notify Me When Back In Stock" and enter your email.

This is the best way to get the information you want.

Best, LB

Thank you! I did set up to get notified when back in stock

[jetfool]

Dan,
I agree with you. Going to be a roller coaster ride for a while. I stocked up on everything I thought I'd need and purchased the F-4 Phantom before prices went up or out of stock. Planting a larger garden this year, wife cans food so models and food are taken care of.
Best Regards, Rex

[Grossman56]

Just a guess, but I'd say that we probably won't see any new stock until the tariff issue is solved, then, hopefully, we'll see the Golden Age of RC begin with reduced prices and plenty of selection!!

Does anyone know when Motion RC will get these back in stock?

Dan,
A new FL 1600 Warbird would be great. I'm plane poor at the moment but an SBD-3 Dauntless would be nice. You could paint a pilot and gunner, and a scale cockpit detailed out would keep some of us busy next winter. Just assembled the FL Phantom and finished a small 3d plane I bought at Toledo. Now back to finishing the P-47. Tell Dave I will contact the HS class next week.
Best Regards, Rex
