Official Freewing Twin 80mm/90mm A-10 Thunderbolt II Thread

I just thought of something else from my flight this past Sunday that has been troubling me a bit. I'm running a Lemon Telemetry RX and have the voltage probe stuck into one of the cell voltage wires in the balance port. So, the Main Battery Voltage reads 4.2v at the beginning of flight and counts down as that cell voltage drops. What I noticed, a minute our two into the flight was that the cell voltage was announced as 3.0v. I nearly panicked and landed the Hog PDQ. On the ground, the static voltage was 3.6v, and when I checked my max and min log on the TX, the cell voltage had dropped as low as 2.8v. When I ran up the engines again, that cell voltage dropped to 3.0v again. Are you guys seeing a 0.6v drop in voltage under load? It scares me that it's dropping that much because somewhere around the low 3v range, the ESC will stop supplying power to the engines.

Hello, and Happy Easter. I am new to Hobby Squawk and I just ordered my 80mm A-10 today. I tried to read all the post from day one, but it's gonna be a minute before I actually catch up. But some of the ideas and paint jobs are truly inspiring.

Welcome Errick, I be a 'newb, too. Ordered an A-10 yesterday. I have a Phantom on 2nd round pre-order and presume this will be a great summer for edf's at my house. The guys and gals here are just the best and offer sage advice. I could not be happier with my return to the hobby. Post your progress with pics and vids. Best, Elbee

You guys are going to love the A-10, by far the best EDF out there. I enjoy every minute flying the hog, the new Phantom is awesome too but there is something about the hog that makes it the best, it does everything right, I guess that is the way to put it........:);)

Gotta pass time somehow while it's too windy and wet to go flying. I might have gone overboard with this one:).

Now to see how well it prints.

Nice!!!

Sounds a lot like batteries that are past their prime. It's normal to have voltage drop under load compared to at rest, but this is much. Check internal resistances.

Yep, 0,5v drop under load strikes me as too much, too. Will definitely check these batteries before I fly them again in the Hog.

I Also have The FREEWING 1700 mm A10, and I have 6S, 4500mah, 45C batteries for it. I Wonder if I fly it mostly at 1/2 throttle how much flight time I should get. 4 minutes maybe?? LOL.

You'll get less than 3 minutes .............. "maybe"! This thing was meant for 10,000mah of batteries and then you might get 4 minutes. You've only got 9000mah with those. You'll burn up some of it taxiing out and then a bunch more taking off. Do a couple of small circuits and land. You might get one go around if you flub the first attempt. If you fly this at 1/2 throttle, you should have gotten a Piper Cub. It's about as thrilling.

[F106DeltaDart]

It really does depend on how you fly it. I can get 4 minutes out of it with my Admiral 4000s without too much of an issue. However, I enjoy flying it slow and scale, and even occasionally gliding. It still surprises me just how well it glides! I still mix it up with a few loops and rolls with a few blips of full throttle, but I don't stay there long.

The Piper Cub comment seems a little harsh there dude. I fly the hog at half speed most of the time and I think that is actually too fast for scale speed. I do agree about smaller batteries being an issue if you have to do a couple go arounds. You need that safety margin IMHO.

You can possible get near 4 minutes, but that will take a LOT of throttle management and calm flying.

I had about 5 minutes total on mine, including taxi, so a tad over 4 minutes airborne, with 5800 batts.

Same here. Before getting the model, my biggest concern was whether I would be able to make it behave slow and calm enough for good scaleness. It certainly did not disappoint at all in that regard.

Harsh? I guess the humor was lost on you. I can't help that. Just as you calling me "dude" offends me. I take offense at that term being used in this context but then, you can't help that either. Why do you get offended by a comment made to someone else. Oh look! Someone gave me a "like" for my post. I guess the humor was NOT lost on someone else.

[ColtPilot]

I can do every maneuver in the book at half to 3/4 throttle giving me 4.5 minutes with some left to spare just in case. I'll leave the Cubs to the Cub flyers. Love this A-10.

It was me

Sorry dude, I mean man, or fella, or guy.:) The word dude is a pretty common term around my area and no offense was meant. As to taking it wrong, LOLthese smilies are supposed to help with that so nothing is lost in the typing. Didn't see one of those. As to being offended by your comment, I wasn't, but having said that. I hate to see anyone capping on someone else, especially a newbie. So again, I apologize for misinterpreting your original comment.:Loser: Back to the hog trough I say.:Cool:

Apology accepted. I should have used a smilie. It's just that your post was very reminiscent of some of the weirdos on RC Groups, which I despise and try not to post any more than I have to there. A few of those tend to do a "gang bang" on someone just because they feel the need to belong to a group greater than themselves. To me, "dude" is a term used with light hearted conveyance of a form of addressing someone (like "sir or mister"). However, when used in certain context, it's a derogatory term used to put someone in his place or to stifle his point of view when that view is interpreted in a negative way and we all know, interpretation is in the eye of the interpreter.
