So I worked on the design some, and decided (despite what I said earlier) to make changes to the wing in order to up the area. I got it to around 225"^2 Now I think this plane should fly just fine

Here she is!

So far 110 grams, with all 4 servos (Futaba S3114), linkages, and carbon fiber reinforcement.

I have an Axi 2204/54 that I planned to use on it, but it looks like its gonna be wayyy to heavy, so I will probably order a MicroDan, which will get me to around 150-160g RTF. Looks like it will be a few more weeks till she flies

It flies!

The maiden went great. I had to guess on the CG but I guessed right! It rolls spectacularly, straight as an arrow. The elevator and rudder are not as sensitive as I would like, so I am working my way backwards on the CG. It is surprisingly floaty despite the high wingloading.

I ended up getting a Hacker A10-9L motor, spinning a GWS 8x4.3 SF prop. I am running the Hacker on a Turnigy 300 mah 2s, but the flight times are quite short. I'm using a Turnigy Plush 6A, is this a high enough amp rated ESC for the hacker? The recommended ESC rating by Hacker is 4-7 amps, but my ESC does get warm after only 30ish seconds of running the motor. The motor gets warm after a flight, and the battery too, despite its 35-70C rating.... Do I need to change my setup? I ordered a 10A Turnigy Plush which i can stick on the plane.

It came in at 169g AUW, and with 225 square inches of wing area, it has a wing loading of roughly 3.85oz/ft^2. Despite the high wing loading its still quite floaty, which makes me happy. I think there is room for a larger battery considering the ballistic vertical that the hacker provides

I already have a V2 in the works. Its got 37" length, 35" WS and 250 square inches of wing area, it will either run an Axi 2204/54, or a Hacker A10-9L.

Here is a sneek peek Milled parts weight 38.1g V1 (unmilled) weighed 35g

I have decided to name it the Axiom.

Hi, nice work!

Same motor, prop and I use the X 5 pro from Hacker. No warming and no issues. Just program it for your needs.

I calculated my W/L at 2.7oz/SF for this model. Note it is a freestyle design but will do F3P with a good set of hands at the sticks.

Thank you! Is that the Metis? It has really nice lines

What is the wing area on that model? Your loading is quite low

It's the Metis. Most fun I've had with a depron model.

I have about 270 sq inches by my crude calcs.

Hmm, I think Im going to have to change my Turnigy Plush 6A for the 10A, the BEC on the 6A (5v/.8A) is too weak. The 10A has a 5v/2A which is much better.

Axiom V2

Hey guys,

I just finished the V2 of my design, the Axiom. I got a quick two flights in today, it flies awesome. Wingloading of around 3.2oz/Ft^2 makes it very floaty. With the Hacker A10-9L it cruises around at under half throttle The milling was definitely worthwhile, it shaved off a good 6-7grams, bringing the depron parts to 38.1g, versus the unmilled, smaller V1 which was about 34.5g

AUW came out at 161.5g, just 1.5g over my target weight of 160g

Setup:

Aileron: HS65MG (running on 6v)
Ele/Rudd: Dymond 4.7 (Running on 8.4v)
Motor: Hacker A10-9L
ESC: Turnigy Plush 6A
RX: LemonRx 6Channel
Batt: Turnigy 2Cell nanotech 300Mah

Specs:
WS: 35.25"
Length: 36.7"
AUW: 161.5g
Wingloading: 3.20oz/Ft^2
Material: Gediplac (I have noticed great weight savings using this instead of depron. I think if i had made this plane from depron, even when milled it would have still weighed 3~4g heavier than the gediplac)

By running the servos (Dymonds directly from the 2s lipo, HS65 on a 6v regulator straight from battery) I bypass the BEC on the Plush 6A and dont have to worry about overloading it
