FoamyDM - EZ Viking S-3b

[FoamyDM]

I have a project building a Master series style Viking S-3b. (Link here). I just got my EZ kit, and thought I should make an EZ scale is the Viking S-3.

The other day I made a paper pattern to about 18" wing span, using Dollar General Foam Board (3/32" thick). I used poster board for patterning.

Then started cutting. And before long I had a working model. (no glue) I used the big model c.g. (note the 2 dots)

From this it was time for a glide test in the yard:

Based on the tests it clearly glides well. The balance might be a hair tail heavy, and it tip stalls.
Likely, it will fly well with the motors.

That looks really good in the air. A couple motors maybe a stablizer I could fly that all day. Or till I run out of batteries

I tried the c-17 control board, with some E010 19000kv motors with Tinywhoop props and I didn't have much success, yet. Could be needing to set it up differently. I'm not sure yet. I'm still working on it.

However, for those more adventurous, might I suggest the MMS (Micro Master Series Viking S-3b alpha). No working landing gear, (yet). Glide test forthcoming when the grass dries.

Although if it works... This is a ~1:48 scale. a similarly scaled Nimitz would be 22.5' x 5.25' x 1.5". (almost reasonable.) I know a British carrier would be smaller.

Love it!

Did this go Whoosh ZOOM!!!!1 yet?

Did this go Whoosh ZOOM!!!!1 yet?

ROFLMBO I remember that sound well. I remember hearing the Hoovers on final everyday. Living under the active runways flight path was such a joy. LOL #SoundOfFreedom

 

[PsyBorg]

I just thought back about them wrist rockets getting tossed off Nimitz by the cats. That is actually the sound you here WHOOOSH!!! Zoom!! with a slight shudder under your feet.

 

[FoamyDM]

No. no Whoosh ZOOM!!! yet. The gear is slowing me. But as the nacelle's are in line with plane bottom, the gear are important. I built the second EZ version, is built and it glides very well.

Today I discovered why the profile version was turning.... It was the rudder. The AUW is 40g.


EZ - V-3b Viking maiden flight:

This was very easy to fly within the cul-de-sac. And handled the turbulent air in front of the house well.

Plans are on their way. Keep and eye out.

Foamy EZ S-3b Viking 3D. Success with an underpowered system:

Time for drawings.

 

[FoamyDM]

OK, you can thank the FT 2021 Micro/EZ Build Off Challenge for me finishing the Drawings of the simple version of the EZ Viking.
Plans:

It is sized to 11x17. It is ~18" wing span and works off the FT-EZ power system.
