Official Freewing 70mm F-35 V3 (2019 Version) Thread

[Russ]

RcJetDude,

My 64mm Freewing Panther uses nylon hinges stock. $90 plane.

Here is what they say on Motion RC site:

Nylon hinges on all control surfaces (superior to a foam hinge)

I've had the Panther for many years now.

The 70mm Hawk did not.

[Quickstop]

What? no screwdriver....then I'm not getting one!:Silly: oops never mind, I already did!

[Russ]

Good news is your Hawk has lasted, right?

[fredmdbud]

From the many screwdrivers included in previous kits (Su-35, 64mm F/A-18E, T-45), it was no biggie for me. That the screwdrivers were also magnetized (from the handle) sure came in handy. :)

I put the 80mm Mirage 9 blade and 100A ESC in mine :Silly:

Yes the hinges have held up. Even through a vertical fin separating in flight because I failed to install the screws that secured it after having to remove it for transport. :Loser: Even with that though I have found foam hinges are fairly easy to fix with a little Foam Tac and some Blenderm. If they get really bad then nylon hinges are the answer but so far I haven't had to resort to any.

So what C of G did you fly yours on .The manual puts it at the leading edge of the wing but on this forum they are saying 60mm aft of the leading edge .I am confused on where to put my C of G .Need to sort this out before I fly mine HELP

[Evan D]

Cool, have you flown it yet?

Hi CaptainMoron, see James' post on the previous page for better clarification and photos:

I balance my finger where his are in his picture according to those markings, and that's where I've been flying the majority of our test flights.

Here's the foam hinge fix. Its called welder contact adhesive. Rich Baker did a video on YouTube as the rc informer, and shows how it's done. Just did it on my 70mm f16, and it's bullet proof. The video is a must see. Even on a new plane, if you coat the hinge line with a brush it will likely never come apart.

Thanks Alpha, that is different to the manual but looks about right so I will try your C of G .I am sure you are right

[TiredIronGRB]

Cool, have you flown it yet?

Yes, I have 4 flights on it...pretty fast ;)

[Russ]

Will FoamTac work the same way for hinge bolstering?

[Apriliamgt]

This currently where I have the 5000 set to. And using the points James has set out for cg?

look about right?

[RCjetdude]

That is where I have my Admiral 4000 Pro. I would think the 5000 is a heavier battery.

[RCjetdude]

Will FoamTac work the same way for hinge bolstering?

Yes. The stuff is great for it.

I've used this to great effect, made a hinge for my freewing f-16 elevator and has worked great for over a year now, very strong and very flexible. There are a bunch of different kinds. plumbing household, etc. but they are all exactly the same.
