Is that a foam core top-plate? Any problems with durability for your plates? To save a couple of grams (maybe 3?), I just ordered ten of your bottom plates (lite 1mm version) to replace those on my 4" & 5" Adam Wilkinson's quads (also on armattan) which also use a 30.5 / 20 mm stack arrangement. My quads have 4mm thick arms @ 4gr each for the 4" and 4.7gr for the 5" (seem light enough), but the plates are really thick and solid @ 3gr which I think needlessly adds weight. I really like your 1mm plate design - any idea on durability or weight? (I'll find out soon enough ;) Also, I was curious if you have weights on your 3" and 4" arms? (maybe I'll upgrade those too!) Thanks for making your parts available on Armattan!

Sorry I took 25 days to reply (I'm not very active on here anymore). Its cool that youve found some use for my centre plates on a different quad! The top plate on my build is actually a power distribution board made of fiber glass. Foam core plates would be cool because solid carbon or solid fiber glass plates are more durable than they need to be on a 3 inch I reckon. Unfortunately I cant remember any exact weights of my parts but I think the 3 inch arms were around 1.5g.

I got your top & bottom plates and weighed them @ 1.31 grams each (weight averaged over 4 plates). This has saved me almost 3 grams on my Adam frame! Thanks for making these available on Armattan. In the small chance you might be willing, I was hoping you could offer your 3" arms with screw holes for 11xx motors (I want to install 1108 motors)... I guess I can dream ;)

Love this build! What does the frame weigh? And your build?

crz55 Sep 29, 2017

Cheers! My build weighs 116g without battery. Haven't actually weighed the frame but would say it is around 20g with steel hardware.

Loving the pod design! Definitely gonna order one of these frames. :) Where's that PDB from though?

Yeah, you can see where I got some inspiration!

I'm diggin' it too! just got one of armattan productions, really feelin' this frame! looks awsm! the pdb was not an option tho, where did you get it from?

crz55 Jul 19, 2017

Thanks, I wish I could offer the PDB with the frame but I don't think that's possible on Armattan Productions yet. See one of my previous replies (above) where I posted a link to the PDB on OSHPark.

Really cool frame! is it possible to fit 2 20x20 boards or would that be too tall? would like to use a 4 in 1 esc + fc.

crz55 Jul 16, 2017

Thanks heaps! Yeah, my build uses 25mm screws for mounting the pod and might just fit two boards under it but longer screws can be used if you need more headroom.

J-Lar Jul 16, 2017

Awesome, might have to order one, probably gonna get some longer screws as well just in case.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
