Frame is complete.

A few changes that were made;
obviously removed the servo and yaw control, replaced with a V tail. Each rear motor will be faced down, at a 30 degree angle.
Positioned front arms forward. Increased the amount of useable space inside the body cavity for ESC placement, wiring, etc.


Distance between two front motors: 700mm


Distance between front & rear motor: 550mm


New arm placement. Note the marked lines which shows previous arm placement.


Closeup of rear V-Tail mount.



Can't wait to see this thing in the air again!

I guess the next step is to finish the wiring and mount the motors. I am alittle concerned about the weight of the frame, but I am confident it will take the abuse I am sure is to follow.

hey those arms dont look as if they are at 120' ...have you purposefully kept them at a higher angle ....what purpose is that going to serve??? except make the craft more difficult to stabilize for the board....

The board wont care, and will compensate i am sure. I did it to help with orientation.

I'm sure it will compensate, but I think the concern would be significant differences in RPM/loading of the motors might lead to problems or at least require some interesting mixing.

AKA, you don't like to make things easy on yourself... do you :-)

Where is the fun in that?

See my other build thread for my 450 quad ( http://www.rcgroups.com/forums/showthread.php?t=1752736 ). That thing bores me. I had it fully assembled, from a box full of parts to flying in my front yard, before my son ever woke up from his afternoon nap.

Besides, I have seen T-copters fly, and spider quads fly, and i am certain the flight controller will do a good enough job compensating that I shouldn't notice a difference. I suppose we will just have to wait and see.

Got the landing gear figured out. A huge thanks to Snipeworm for hooking me up with some pool noodle!



Tomorrow I will complete the wiring harness & get the ESC's mounted. Then work on a decent battery mount and i think we'll be set!

Holy crap! Haha I left the forums for a month on an overseas trip, and I come back to see your ugly tri has turned into a meaning looking V-Tail!

Nice work mate, I'll have a tonne of questions for you when I start my build if you're willing to put up with!

Have you considered mounting the battery, control board and camera onto a seperate plate? If you attach that plate to the main body with thin, rigid piano wire - it'll act as a dampener and stop vibration affecting the camera and gyros on the control board.

Here's a link to it on rcexplorer site - looks pretty ingenius.

yeah I thought about it. I have some wire rope that would work great for this, and doesnt look terribly difficult to fabricate.

I wouldn't, I'd keep it close to the centre of gravity but you need the mass of the battery to stop the vibration.
