That's the plan. If I don't like what I get with the 5 inch props, I will back down to 4 inch props. That IS the beauty of using a frame for 1 prop size larger. The Flywoo FC from RDQ has just arrived today, so I can get on with the build.

Stay tuned .... 

Staying tuned! ❤️?

Yeah, I know, it has been a while. I just had a lot going on and still collecting things for this build. 

Guess I am following Snow for long build time. Ha, Ha.    Anyway...now I am getting back to it.

I have received fiberglass sheets and have been redesigning the frame...will be cutting fiberglass soon. I am anxious to see how the weight compares to carbon fiber. Since a unibody frame is harder for me to fabricate, I am going with a multi-part frame; separate arms and central fuselage plates. An advantage to a multi-part frame is that I can swap arms or central plates and get different configurations.

I am also working on a holder for 18650 cells that somehow will incorporate into the frame.

I have been working on fabricating a custom frame which has been a little more interesting than I would have thought. I have went through a variety of designs. I tried to incorporate the 18650 holder, but nothing seemed to work out the way that I wanted. So...I ditched the idea of an incorporated holder and worked to simplify the design. Keep in mind that I don't have precision cutting devices so this is all fabricated with hand tools.

At 32.5 grams, the frame is little heavier than I wanted, but I decided to leave the arms wide for strength rather than cut them down or skeletonize them. The arms are also long enough to accommodate 5 inch props. I could probably shave off several grams from these arms; plus, a set of 4 inch arms will be lighter; I will likely cut new arms which will be shorter and I might cut down the width a little, too; if I decide to go with 4 inch props.

intressting material choice, i always liked to get one of those fpv360 frames :-)


why did you choose splitarm over unibody?
edit; found the answer in post #41

i builded with a buddy a quad 1404 2750kv on hq5030 biblades at 100g weight, we didnt try 4inch - we got 35min of true flighttime with gently freestyle. i dont remember the used battery. i cant imagine it can be even extended with 4inch :-) awaiting your results ifly :-) believing it will takes some time - in the aimed way ;-)

Hi Bat,

I am hoping to keep the total dry weight as close to 100 grams as possible...and the race is on.

Now, the actual build begins.... stay tuned...
