HSD 105mm F-16 EDF Jet

[PaulZ]

Thanks Lcacing I just flew a bunch today. I am going to move the CG even further back next time. I was at 168mm and had to trim the elevators right down to the edge of the fuselage, too far in my opinion. The book has CG at 178 and I am wondering if that may be better. Still without the TH-ELE mix...that thing is truly unnecessary.

[Aros]

I was thinking 165mm for the maiden but now I am thinking that might be a touch nose heavy...Maybe I will maiden at 170...No mixes, straight aileron/elevator. This is one model I always tend to overthink due to the flying space constraints and high approach for landings...I've had some flights where the drive home was pure elation and happiness, and some where the drive home was seething anger and regret, lol.

[Lcacing]

PaulZ 2mm is about where mine are. Didn’t see any trim adjustment from 168 to 170. The elevators are not neutral even at CG 170 so probably there is still room to move the CG back a bit more. I might try 175 next time I fly.

[Aros]

PaulZ I haven't been able to setup my new one yet (waiting on the 2S batteries to arrive tomorrow) but I believe I recall on my first two that the trailing edge of my elevators always aligned with the trailing edge of the fuse (see photo)...

[PaulZ]

Guys, with the the CG closer to 170 and no TH-ELE mix where do you have your elevators for level flight? Manual has them at 5mm from bottom edge of the fuse, I'll start with 2mm and see how she flies.

Roger that Lcacing, thanks for the info!

[Lcacing]

Aros in stock set up, the MFC has double servo outputs On the main controls and servos are connected that way, two servos per channel. To be able to set up stock controls and a condition for tailerons, flaps, and flaperons you will need to connect each surface to its own channel. The MFC has plenty of spare channels to do it. Then all the mixing is done at the transmitter

[Aros]

I haven't heard anyone try anything beyond 12S for the EDF version...I don't want to be the guinea pig.

[lauterbacher]

These F-16 still need more power when are one of you going to try 14s. for the most part all the ESC's that handle 12S also handle 14S

[Aros]

lol I think you're right on the same photos...Thanks for the info and vid! Now about the controller...Do you have to manually set everything up through it or can you still hook up your rx and use your radio for setting up like usual?

[Lcacing]

Let’s try it again

[Lcacing]

Aros I think everyone that gets the HSD F16 takes the same picture.....I did lol (A10 has 90mm upgrade)
Tailerons are actually less sensitive than ailerons since they are closer to center line but are responsive. It makes the rolls more scale, not axial, plus with rudder input they look great. Just create a condition so you can have both modes.
Here is a quick video of the 3 conditions I had on maiden.

I got her today...Dang I forgot how big she is. Here's a photo next to the Freewing 90mm, and she ain't no slouch either. Flaperons I get for shorter takeoffs and slower landings but tailerons makes me think hyper-sensitive roll, no?

[Lcacing]

That’s exactly what I’ve been saying, T/E mix off and CG back near 170mm. Now if you want an even nicer scale flying model add tailerons and flaps.

[Aros]

Nice! Yeah I am with you PaulZ , I don't see the need for that throttle/elev mix. There's got to be some science behind it I guess but I never understood it and always deactivated it.

[PaulZ]

Aros i I flew mine today with the TH-ELE mix turned off to see how it would behave. I like it much more, now the rolls are clean and axial. A great model flying even better. With the mix turned off my CG is now closer to yours at 168mm. I am not sure why HSD ships these with the TH-ELE mix turned on, maybe something to do with the fact that the same controller is shipped with the turbine version? Anyway the TH-ELE mix is staying off now.

I've had mine for about 3 years, so I have the one with 150 amp esc in it. Haven't done much with it past year, but looking at improvements that have come along, I plan on getting the new HSD fan when it comes in in mid May and the newer control box.
has anyone converted their older model to the newer control box? What was the difficulty setting it up?

[Aros]

Initial tracking said it would be here Friday. Now it says Monday. Dang tease.

[Aros]

Thanks for posting that PaulZ ... Looks like you like yours more reactive/responsive on the sticks than I do. For me it's mainly because of the area I fly is a lot of Pucker Factor with the buildings, trees, poles, etc. So I like to feel that she's as smooth as possible in all axis' throughout the entire flight envelope...Rolls are pretty scale looking, still maneuverable enough to get out of a jam if need be. I suspect if I had the unobstructed open land to fly her that I would love, I would open up the rates more. As for the throttle/elevator mix, I think I did use it on my first one for a few flights but shut it off. I think it's because I read enough about it from others that I agreed it was just one more mix that could create an issue if something went wrong...Isn't it also a CG issue when the gear is retracted? I can't think offhand what it's main purpose is for?

[PaulZ]

How does it fly inverted, always wondered how it would react with the throttle/elevator mix on.

With only a slight touch of down elevator. I am also surprised that the TH-ELE mix does not impact inverted flight more.
