Dynamic tilting arms 330 racer multirotor

Hi guys,

After long time playing with the idea of a tilting arms multirotor concept and several proof-of-concept prototype tests (see Youtube video below) we're ready to show you what's coming guys: a tough, sleek, aerodynamic, efficient and fast (super fast!) tilting arms multirotor.

Name: TILT

Unlike traditional frames that tilt the whole body to acquire forward and lateral velocity, rotating the arms provides greater performance:

  • Less mass to move to acquire forward velocity: higher acceleration
  • Better aerodynamics (especially with a well-designed canopy): higher top speed
  • And more to come
    wink.gif

We started from the ground up, (literally, EVERYTHING has been assumed it can be improved) and we've re-designed the preliminary system shown in the Youtube video (see attached pictures) to exploit new materials and manufacturing technologies for a tough hybrid frame made of 3D printed carbon fiber/polyester blend and traditional CF 3K woven plates and tubes. Other materials are being reviewed to reach a much better toughness but still weight contained overall system.

We can say we are in right track for releasing soon a commercial tilting arms multirotor with improved design, aesthetics, aerodynamics and speed.

Main specs (being expanded and will update them):

  • Dynamic tilting arms system designed for reliability, simplicity while lightweight.
  • 330 system for up to 7 in props. Can use bigger props just changing the woven CF arm tubes (standard D16 mm tubes in the current version, tougher arms coming).
  • Low profile, super tough hybrid frame (3D printed CF + regular woven CF plates). We won't compromise on this, this system must be fast and tough! Extra rigidifiers not shown in the pic below
  • Front and back replaceable plates. They are being designed to absorb as much energy as possible in case of a crash. They will allow for mounting different things like different cameras.
  • Motor mounts ready for X8 configuration
  • Battery tray system that avoids continuous CoG balance every time you change the battery, even if they are different.
  • Aerodynamic canopy to reduce drag and protect the system.

The tilting system is governed by an open source code that anyone will be able to tune (although it will come with pre-defined modes for those not wishing to modify it).

Keep an eye here, we'll be posting the development and (probably next week) a maiden of the new system!

The frame is basically finished and with the motors mounted. The actual setup is a 330 motor to motor (can obviously be modified changing the CF tubes) and for fit purposes in the pics I mounted 7x4.5 HQ props. Who knows, I might actually give it a shot with this combination: Cobras 2208 2000kv and 7x4.5 props on 4S... Let's see!

I must say it feels indestructible and tough, crash tests will confirm that or provide information for improvements. Can't wait...

##############################################

Verifying of CoG within a certain 4S batteries' range (2200 to 2700 mAh) and for Mobius and GoPro cameras. Deviations from those capacities will still be possible of course. Now we can design the canopy around the system. Canopy coming soon....

##############################################

All the mechanics finished: battery trays with logo, top rigidifier and antenna, cameras and servo supports. It's damn stiff but tough (tests will confirm that. Tomorrow is electronics' time and maiden afterwards.

Can't wait...

##############################################

13th March 2015: Today I've maidened the quadcopter indoors and worked great. Even no jello at all with the Mobius directly on the frame. This weekend the real maiden. Will post videos as soon as they are ready.

Nice idea- looks effective and you could well be onto something here.
 


Bartman

Welcome to MultiRotorForums.com!!
nicely done, Kilby and I had talked about a concept like this but neither of us ever had the time to get to build it.

good luck, looking forward to seeing your results (and may still build a prototype of our own at some point!)

Please do and let us know how it worked for you!
 

Hey, that looks pretty cool, I just finished building a Tarot 810 and was thinking about building a racer, now I'll have to wait and see how this works out, it looks like it will be fast!
 

Good news guys: I've maidened the quadcopter indoors and worked great. This weekend the real maiden, can't wait. Will post videos as soon as I can.

Happy flying!

Hi guys,

Been super busy with the development bc we approach the pre-order date! Will be from May the 10th (will post site here) and first shipments beginning of June. If you want me to keep you updated directly, send me email to pau.mallol@inkonova.se

Some summary of what happened until:

- 6 PDBs arrived: awesome stuff!
- We got two complete pre-production kits (the 3D printed parts in Carbon fiber) with PDBs and started assembling them with different motors and ESCs.
- CNC parts for two kits are awesome: aluminum alloy anodized red and black (depending on part) and Delrin
- We got most of the wholesale prices (Cobra and KDE motors, DYS SN20 ESCs, Tiger, original Naze32 ...). Waiting for SunnySky and discussing mfg costs of the parts.
- Test pilots have been already providing useful feedback for coding the tilting algorythms on Cleanflight. So far we are testing four different strategies with Yaw/Roll interaction and Thrust compensation, already on Cleanflight.
- Today we've shot the race part of the promo video we'll have: we raced against a Lamborghini!
- E-commerce platform (webshop) is coming along very nicely
- Resellers are becoming interested. After the pre-order period (May-June for now) we'll sell only on establish webshops (at higher price as the shops add their margin)

See picts below, more on Facebook ('Pau Mallol')
