This was my second attempt at a MiG-21, the first used the same power set up but was smaller and had a higher wing loading, and it needed improvement. This second version is bigger and has a lower wing loading and flies much better. In the spirit of Ben's F-16, I left off ailerons and used only...

This is the print file for the custom EDF motor-mount-ducts that I designed for my 7ft B-52. It has been updated to work with 2" props, and has motor mount holes for the 1106 size motors.

Here are plans for my 7ft span B-52, powered by EIGHT 1106-4500Kv Gremlin motors. It's a pretty simple build, but for more info visit the forum thread!

So I'm in a slightly awkward situation. I have an X-29 with movable canards and modified with a landing gear. I'm unable to get it off the ground and I think I'll get one flight out of it then build something else, already lost my patience with that one... I also have two 1100kv NTM 28-26 motors...

For this 2018-2019 Build along, I plan to build The Ductinator-E by Ziroli I scored from a hobbyist who cannot continue building for health reasons, and a member was helping him unload them, bought for a steal. The EDF just came in. (my other kit is a Contender 40) I have NO Balsa Build...

Inspiration: 90mm EDF, 80A ESC and 3000 6S battery with no plane. Looked around, the diamond looks appealing. but I thought about what else... and decided to design the Romanian Air Force IAR-9 SOIM (hawk) Plane Specs: from the Wiki Page: General characteristics Crew: 2 Length: 11.01 m (36...

Is anyone flying the X-29 with an EDF? Do you have any recommendations for the EDF and ESC? I know they mention a 70mm EDF, but I have no idea what RPM, cell count, or Amp ESC. Any help would be appreciated!

Here's my take on a ~28" wingspan Foam Board EDF F86: I'm personally extremely proud of this design, especially the Mk2. To be honest, it's the fastest aircraft I've ever flown and it's probably beyond my skill level to fly. So I decided to share it with you guys, hopefully, some of you will...

The F-14 has some of my favorite curves of any jet, and I would love to scratch build one out of foam. So, I'm here to begin my efforts! I'm still in the process of drawing the plans and I am totally looking for any advice anyone has. This is also my first build without anyone's plans to hold...

SPECS Span: 30 in. Length: 43 in. Empty Weight: 27 oz. Power: 70mm EDF Battery: 3000mAh - 5000mAh 4-cell Lipo Flying Weight: ~45 oz. I highly recommend a 12-blade EDF, but this jet will fly on any similarly-powered fan regardless of the...

I worked on a MiG-21 for a while and that had a really high wing loading so I want to try something in the opposite direction. The U-2 is one of only five planes in service with the USAF for over 50 years and was designed back in the 1950s by Skunk Works. I'm really excited to attempt an...

The F-86 Sabre is among my favorite jets. How can you not love the greatest MiG killer in history? I decided to make the it scale to my F-15. It requires ONLY 2 sheets of foamboard! This means that if you lawndart it (I did the first one!) it's no trouble to rebuild! I used a FMS 12 blade 50mm...

Hello! bought this edf/motor: https://hobbyking.com/en_us/blade-high-performance-70mm-edf-12-blades-ducted-fan-unit.html https://hobbyking.com/en_us/turnigy-2226-3000-70mm-edf-outrunner.html The setup draws 50 amps on a 4s and produces about 700g of thrust with a thrust tube. It would be...

Any ideas on this concept? So you know how jets usually have the engine in the back and some canards in the front, well what if you replaced the canards with the engines (I swear I'm not drunk!). Essentially the concept was for a twin edf aircraft to have its motors rotate on an axis for...

Ok so here goes my 3rd post on this amazing website. To summarize this thread, This is going to be my first scratch build without plans and I was wondering if you had any suggestions. Now that the summary is over here's my idea. The Russian Su-47 has been a favorite of mine for many reasons...

Started scratch Building planes a year ago and have since made 3. Just wanted to see what people thought of it. It's made from foam and balsa, Between raising my 2 kids its taken me 3 months. I'll show the build process if anyone is interested. It's almost finished.

So it started out with a set of 64mm (3S) EDF motors and some 40AMP ESCs. It ended with what appears to be a decent setup. Fingers crossed. The initial glide tests showed me I could move the battery closer to the main fuse and shorten the nose section. The 2nd round tests with flight controls...

I know EDF's are not like a jet engine, but if you added more then one set of blades onto the driveshaft, would that increase thrust? My design is an internal motor with outflow going through 90 degree ducting so it will theoretically have more back pressure. If you connected two or more stages...

I was inspired to attempt to create my own designs after finishing up an FT Viggen. This is a model designed by me although I must admit it turned out very similar to an F-16 style aircraft. I model the aircraft using blender in 3D and then utilize UV mapping and some plugins to "unfold" the 3D...

Hello all, I recently built a twin edf engine plane. However, while running over the preflight checklist I did an engine check and my esc's both started smoking furiously. Both engines were the same, the were the 64mm EDF Viggen package from grayson hobby. Why did they catch fire? I was using...
