Post your Giant scale builds here!
With the release of the new Giant scale Maker-Foam, I had just purchased some motors that spin 12-14" props... approx. 4-lbs thrust each.

IMAA Criteria

  • Minimum of 80" wingspan for Monoplanes
    • Minimum of 60" wingspan for multi-wing planes
  • Ducted Fan and Turbine aircraft must have 140" combined length and width
A true quarter scale RC airplane or larger will be permitted even if it doesn't the above requirements.

Sooo. with the new Maker foam What aircraft should I make?

It would depend on how obscure you are willing to go. In the late 70s The USAF was running a study called the Advanced Medium STOL transport program. One of the aircraft that came out of this program was Boeing YC-14. It incorporated the blown-flaps concept and took advantage of the Coanda effect over the upper wing. Ultimately only 2 aircraft were built though. There is one on display at the Prima air and space museum. It would make for a unique large scale build, and wouldn't take much to get a working model. There are plans on here for a C-17 with blow through flaps, add the forward fuselage of a C-130 (ish) and the tail of an Airbus A-400 then scale appropriately. The engine nacelles can be made by scaling the nose of the FT corsair down to fit a 90mm EDF. If you kept the weight way down you could probably even run a BDF style setup instead of EDFs.

You could probably fly a 100" BV238 off of C-pack motors and still get it to take off from water :p That's what I had in mind for my Me 264 (if I ever start that...) and according to the math I did it should work and that plane is about the same size but with two less motors...

FoamyDM- Thrust reversing engines sometimes create a votex when backing. YC-14 was a STOL aircraft and the thrust reversing was used to aid in braking on short runways with heavy cargo.

@speedbirdted - is that a spruce Gander?
@cgoffroad - Merci
For those who Don't know...Monster Maker foam is 3/8 thick, 30"x40" (creased in half to 30x20). there are 25 in a box. It is water resistant, and translucent (great for LEDS). My local hobby shop is getting some for us to buy by the sheet.

I have two of something like these with the props and escs. This means I have around 20 lbs of push on whatever I build.
I'm thinking two things... either a Large 747 with parasite craft. pusher style or the Crimson Skies heaven's spades carrier.

That would be sweet!

Assymetrical, 3D, Carriers.
I was also thinking large Vampire or P-61 black widow. The front will have to have a Scarlett Johansson nose art
lastly, a Synergy
