Official Freewing Twin 80mm EDF A-10 Thunderbolt II Super Scale V2 Thread

Is everyone flying the book CG ? I saw Jon from 2Bros was 20 mm further aft on his AS3X setup. It looked like it worked well. I am going to put a Hobby Eagle in mine so wondered how suitable his CG was .
many thanks.

You gotta realize that Jon was originally a 3D flyer, so almost everything he flies since those days are balanced "tail heavy". He loves to do "high alpha" on virtually everything. A rearward CG from recommended helps to do high alpha easier. Not "everyone" gravitates to high alpha passes.
For me, high alpha flying gets really old, really fast. I set my planes up at the recommended CG to start and in almost all cases, I leave it there for the entire life of my planes. You should do what feels right to you and not necessarily following what someone else does.

Hi 400driver. Of course “everyone” is a broad stroke. It depends on what flying characteristics you want. More tail heavy = more twitchy in pitch. More nose heavy = less twitchy in pitch…more locked in feeling.

With Admiral 6000s pushed back as far as the hold down straps will allow and still hold….she’s just a touch nose heavy when lifted on the CG mark.

I am satisfied with this CG. She’s locked in and still performs reasonable aerobatics. The only way I can get a more aft CG will be with tail weights. I don’t feel the need to do that.

Your A-10 looks awesome Aros and I also use the Sharpie pens for all kinds of touchups on black painted surfaces or rivet detail like you did. I like the twin tip black Sharpie pen, one end has the Fine and the other end is Ultra Fine.

Thanks buddy! Like minds! They really work great for all kinds of detail work.

[DCORSAIR]

Thank you! I simply used permanent ink pens (fine point) in black and metallic silver. Just light dots along the panel lines and a lot of patience.

I am curious about the optional springs - wondering if they are harder or softer and ...what effect to they have on grass field

Please keep us informed !!

I have 18flights on my FW V2 A-10 and slowly getting comfortable with it....continuing to monitor throttle with flight times for mixed acrobatics ....so far I can toss it around for 6:30min landing and taxi with 3.86v per cell .... very pleased with performance and flight times

Has anybody successfully removed the main wheels to try the two springs in the included hardware bag? I've removed the grub screws on both, but can't rotate/loosen the main wheel axles. Once I get those out, I should be able to remove the e-clips holding the arms in and get to the landing gear strut springs. Thanks!

Continuing my test flights of this new FW A-10 at AMA#1140 Greater Southwest Aero Modelers of Fort Worth Tx grass field:

Confirming full armament 6min flight duration with mixed throttle and acrobatic flight routine (Aileron rolls, Cuban eight, figure eight, loop, Immelmann, split S, dirty pass, lazy eight, fast pass, slow pass, vertical climb spin into descending 360 power glide etc etc) landing with taxi via SMC 5900mAh LiHv at 3.85per cell. 7min flight times cruise landing at 3.80v per cell.

Be careful of touch-n-go to ensure enough runway is available for "Slow throttle increase" rotation for rollout take off....otherwise aggressive throttle input will hold the nose down causing long runout for take off.

The flight envelope of this twin EDF is impressive ....very responsive aggressive flight performance with Aft CG. Flight duration of 7min display cruise is astounding

I did see gyro undulations at 100% throttle nose into 13mph winds......so be mindful of possible gyro flutter at WOT.

Take off flap setting works well for landing, full landing flaps may work better by refraining from elevator flare to prevent secondary lift (bounce)

Okay your link shows what I wanted to know, thanks. So my choice of Lipo would fit perfectly,
Thanks and regards

Hi. Question about the ESCs. Are the 100A the long term current or only short term? I would like to fly 6s 5800mAh 30c (long term, 174a) lipo 60C short term

Thanks, regards

Long term, short term? This is a new designation to me. You are describing a LiPo battery's "c" rating, not much to do with ESCs. Long/short term for batteries is also unfamiliar to me.
Here are some specs on the ESCs:

I've seen them described as "continuous" and "peak" (or "burst").

The feeling is mutual my friend!

I forgot to post a picture of the whole darn plane

In the primary language of Miami, Que Bueno!!

Great work on your "Hawg", Sir.

She's a beaut.

Here at the Squawk we are fortunate to have many "gurus" in one form or another.

There is a delicate masterful balance between humility and confidence that many share.

I am proud to know you all.

Best, LB

Ahh the classic Sharpie! NICE

Aros can you post a pic of the pens?

No problem!

GURU? You definitely have me confused with others, including Elbee. I'm more of a fraudulent snake oil salesman. :partying_face: Give me some cans of spray paint and florescent colors and I'm happy as a pig in :poop:

Add self effacing to your fine qualities young man!!

[Hugh Wiedman]

Only 1. And only 1. Person. U me or anyone else needs to please is yourself..... And if U can please hugh along the way all the better 🙏. Cause he is the guru
