Something a bit different.. K-frame 700 AP Stretch

nightflyr · 10-28-2011, 05:49 PM

Taking this 600 design...

http://www.helifreak.com/showthread.php?t=325284

and stretching it out to 700 for a AP rig.

The frame set happens to be incredibly strong and rigid and should make for an interesting build.

tott · 10-28-2011, 06:03 PM

It would make for an interesting build.

I am not so sure how WELL it would translate for AP though.

Being a full "rigid" frame, it may cause and or carry more vibrations. This could be a good thing in that you would be able to trace and eliminate all or most vibrations because even the smallest one will show (I would assume anyway). OR, it could be BAD in that you may forever be chasing vibrations and looking for ways to help absorb some of those vibrations.

I think that is some of the advantages that are built into semirigid material (G10, thinner CF, etc).

I am NOT a designer / builder so these are just my thoughts after OWNING many many many different designs for AP use.

Either way that design of those frames are awesome. I would like to see this build....so if you go for the Ap build PLEASE keep us posted.....

It's actually half & half, the bottom half is designed in G10 as a break away section to save the upper mechanical.

In any case it should be completed by this weekend less the camera mount need to test fly it first

Goldenhour · 10-28-2011, 07:13 PM

Did you CNC that yourself? It looks freakin beautiful.

tott · 10-28-2011, 08:33 PM

@ nightflyer......Yeah I saw the 1/2 and 1/2 for materials. With the TOP 1/2 having all the mechanical movements from servo throws to mainshaft rotation to tail connections, etc. This is where the vibration would manifest from ......and having no material to help soften such .........may become a problem. THEN, again as I said...this is just my educated guess....

I feel the benefit would be more aesthetic for 3d / sport flyers......

Either way....it is a great design and looks great...

nightflyr · 10-30-2011, 04:07 AM

About 80% completed..

Here's what been done so far...
Needed to modify a few things in order to get some items installed..

Main shaft bearing block assemblies...

Needed to rework the Scorpion 50 series motor in order to allow it seat correctly between the frame set. ( this was designed as a 600 so in order to fit over sized components a little modding is required)

3rd bearing block fits like a glove.
Along with a pair of 6S 5000 long packs

Cyclic servo install is straight forward.

Fitted an ICE2-80HV with a set of additional caps

For the preset I'm using the 3G along with a 750 tail gyro, needed a place to mount the 750 which was fairly easy to do.

Yes I know it's a bit untidy...
As soon as i complete the setup on the 3G and tail gyro it will all be dressed out

Navigator53 · 10-30-2011, 10:08 AM

Saaaaaaweet Night

Will be interesting to see this bird fly

Man that's a big freakin' motor!

pril250 · 10-30-2011, 11:00 AM

Night, is the tail drive going to be TT and if so is it based on Trex gearing system or propriety?

nightflyr · 10-30-2011, 12:22 PM

It should be a TREX 600 TT tail set, but .....

Can't leave well enough alone, it's fitted with a 700 TT tail assembly.

About 95% completed...
All the electrical is done, wiring dressed in..what little soldering is finished.

Just need to do the 3G setup and tail gyro.

pril250 · 10-30-2011, 12:45 PM

Can't wait to see this airborne on its maiden

Luvmyhelis · 10-30-2011, 01:32 PM

Once again, outstanding work!

nightflyr · 10-30-2011, 02:02 PM

Completed..

Charging up now..vid to follow

nightflyr · 10-30-2011, 03:46 PM

K-Frame first test hop..

YouTube

Navigator53 · 10-30-2011, 04:47 PM

Looks good from here Night

How'd it feel to you?

I'm saving this winter for an 800 ebird, ya got me hooked (Psssst don't tell Stumblebee)

pril250 · 10-30-2011, 04:59 PM

Well you got there, outstanding work if I may add. Surprised how far forward the packs need to be in order to counter balance the tail. Since this is built with AP in mind (presumably) then once you get her right and assemble the AP gear then the pack will move accordingly for perfect C of G. Well done mate

BTW I noticed lately that the light and sound levels on your videos are somewhat lower than previously making enjoyable viewing borderline......you see we need to see the details...

PS It looks like the exposure may be set for the background which obviously is well lit by an autumn sun shine.

nightflyr · 10-30-2011, 05:25 PM

Broke out the laptop and did some tweaks..

I think it is as far as I can go with the 3G for the present... Will see about ordering another BeastX..

Though it is far more stable in the second test hop..

kregan · 10-30-2011, 07:11 PM

Very neat! That is one long battery pack but it looks like it fits great.

nightflyr · 10-30-2011, 07:55 PM

Like a glove

nightflyr · 11-04-2011, 08:02 PM

Well in order to get this machine where it needed to go...

A few custom pieces were required..

Combination motor mount / camera mount (excellent work Kelly

)
And taking the original 600 design and doing a 700 stretch to it required a set of laminated lower frames to take the extra load.

Test hop the new layout tomorrow weather permitting

nightflyr · 11-05-2011, 04:48 PM

Well this just proved a solid rigid mount is a viable solution..
