After some minor updates and changes, I started my Indiegogo campaign.

Hi, it's me again from Hungary. Let me show my next design, a 480 sizde heli built for FPV and aerial shooting.
First of all, let me tell the origin of my idea. I saw a video from 2012 about a 480 size T-rex sport, with 32 minutes of flight time!!! Although he used 8000 mA with ~1500g AUW, I think with the same weight and about 6000mA battery 20 minutes could be reached.
So I started to design a custom heli based on T-rex 450 PRO parts, pixhawk controller and Mobius HD camera with 3-axis gimbal. Since vibration is quite a big problem of helis, I separated the frame into two main parts and connected them with rubber dampers. I hope high amplitude low frequency vibrations can be eliminated from the lower frame part:
To avoid vibrations from tail drive, I decided to use Direct Tail Drive instead of belt or shaft (thanks to Robert Lefebvre's idea), I found a suitable Hacker motor.
For materials I'd like to use 1,5 mm G10 for frame parts, 2,0 mm G10 for gimbal holder plate and 2,5 mm G10 sheet for battery tray. Gimbal parts will be 3D printed. Aluminium parts will be CNC machined.
Now the 3D model and the part designs are ~90% ready, for further optimisation on parts I will need the electrical components, motors, rotor parts, etc. to colledt dimension datas andexact weights. Now this modell takes ~1550 g of AUW, I think 50-60 g could be saved with parts optimization. Solidworks can also calculate the CG, now it looks like it is OK. But CG will be tuneable with battery position too.
Since this heli will take a lot of money, I'm looking for sponsors because I don't have enough spare money to build this project. If can offer the complete 3D solidworks model and 2D drawing of all custom parts for producing of course. (BTW I don't want to sell this heli as a kit or in any other way, I don't have enough time and energy to give support for customers, produce parts, etc. I can't quarantee the success, but at least I hope... :) )
So if you like my design and would donate me you can do it by Paypal or you can send me any of the missing parts instead. Just connect me by e-mail (nhadrian @ gmail.com) for further informations.
Here is a continously updated parts list. The red colour shows that the part is still missing, the green means I already have it. Further renders and pictures will be shared in this folder continously.
Many thanks in advance.
