FOAM BOARD HJK SPEEDWING DISCUSSION

[Mr Man]

Nowhere near as aerobatic as the Ultimate 3d though.

Decent, my motor melted through the firewall though, and now I've already robbed it of everything😂

Just thinking of building one.....

Maybe not enough throws?

No, I had a ton of throws, probably just nose-heavy. (it still flies nice though)

 

[Mr Man]

Correction: flew.

If you want to fly 3d, there's this: https://www.rcgroups.com/forums/showthread.php?4727661-Flex-Innovations-Mamba-10

Oh, sorry misread 🤣. Hopefully before July! I had to redo the fuselage cause it was too wide..

sad I would really like to see ur plane in the air before the end of the week but seems it might not happen

im nul I used to hate 3d and aerobatics but after seeing some turbine planes doing aerobatics im actually getting interested.......

and here is a crazy idea put a jet turbine on a foamboard apex phantom...........

and yes I know the foam would melt in 30 sex but either put some of those head absorbing pad thingies that petersripol put in his jet turbine foamboard f18 and some people put on thier turbine hjk big monster and maybe cover just the top part of the fusalage and the top part of the vertical and horizontal stabilizer in a thin sheet of fiberglass

Yeah, I’m trying to take my time and not rush it. Plus I need more metal gear servos and a spar.

why do u need metal gear servos ?

cant u just use regular plastic 9g servos ?

Noooooooooo….. Nowhere near strong enough for the forces that 200mph would create. Plus, it’s just better to play it safe👍

 

[Piotrsko]

Might have to use linear servos, if they still make them. Or steering servos. The control surface engineering blows my mind for those speeds

ohh........I was planning on using standard 9g servos on my apex phantom...........

well ok ok so 2 standard 9 gram servos aren't enough for the wings ok but what if we just used 2 servos on each wing soooo....4 servos in total and then for the horizontal stabilizer we can use 2 servos for that aswell so 6 servos in total would that work ??

also had a question about connectors im gonna be using a 150 amp esc and my battery comes with xt 60 connectors my esc wire is probably 10 AWG and my battery wire is like 13 AWG can I use 4mm bullet connectors or should I go bigger or smaller ?

You could probably use 4mm bullets. That;s what I’m using on mine. (With a 7x15 apc prop it’ll be over 200 Amps!
