FlightLine Fw 190 D-9 Dora 850mm (33") Wingspan - Official Thread

[SanExup]

I thought about a folder too, but was thinking because the cowling is so big that it wouldn't necessarily work as well as I had envisioned. But I didn't try it, so it's all speculation. The apc does work well and I did find some cheap nylon 9x6s on Amazon. And just this week I received this prop, also an amazon purchase via china. I can't speak to it's performance or even balancing yet.

Anyone try using folding props I’ve already used three stock ones in three flights the last one the plane just plopped onto the grass perfect and it broke other than this I’m liking these planes

[SanExup]

I just used a dremel to modify the stock spinner. I took a little off then test fit, take a little more until it's near perfect. I just remove plastic until it works. It will fly fine without the spinner 'cover' I cracked mine and have flown it plenty without it.

I have a spare prop to use now. I also have an APC 9by6, haven't figured out how o use it yet. Anyway, I will use the spare prop first.

No problem. I broke the prop on my first throw of this Dora with an overhand toss onto the dirt. I got lucky as it just belly flopped. Once I got the launch down, this turned into my favorite plane to fly. 3s, 4s both are so fun, slow and fast! By the way I have flown with a non electric APC 9by6 and it holds up better than the stock prop or the APC thin electric but you have to mod the spinner and mounting plate. And it requires a perfect toss. The thin electric works well too and bites the air better. I'm really good at breaking props so the stranger APC is what I use the most. Cheers!

SanExup , thanks a lot for the advices!

I should be able to fix it, the damage is not that bad.

I came up with the 100% throttle with 3S because I heard someone used 60-70% for 4S. So I thought 100% throttle for 3S is ok. Seems I need to try your suggestion of 70% with 3S next time.

Definitely I will try underhand toss next time too. Overhead toss is kinda of hard to control the launch direction. Also next time I think I will use left hand to do the underhand toss too, such that my right hand can hold a bit of up elevator!

Hopefully the third time will be the charm! Thank you again for the detailed explanation!

[SanExup]

long-love-rc I'm sorry man! I hate to say it but it was the 100% throttle part and the overhead throw. It likes to be underhand tossed with a slightly upward angle. And probably more importantly is to have the throttle above 50% and below 80% roughly. The motor causes torque rolling at 100% and the prop is just stalling, not biting the air, at that high rev without the plane moving forward yet. And since the prop is providing propulsion and the motor is causing torque roll, without airspeed the plane most likely just stalled. Again, I'm sorry that happened, if it' lessens the sting, most of us have experienced it at some point or another. If you can fix it with glue, which you probably can. Next go at it, have someone else launch it for you. And watch the MotionrRc videos and watch how they launch it. When I launch mine I am inputting a little right aileron and a little up elevator while at 60% throttle. I hold it behind the wings in my left hand and give it an underhand toss. It flies away nicely. Honestly it was probably the 100% throttle that bit you. Don't give up! You will get it!

Also, my terminology and concept of it might be incorrect, maybe someone else will chime in. I think I'm correct in my wording of what the problem might have been. I know I'm correct in how to launch it successfully though. Again, watch the videos of James launching his Dora. That's how I do it as well.

Edit: I just saw you said it turned right. I can only thi k maybe it was just a bad tip stall...

[long-love-rc]

Today I brought my new Dora 850mm out for its maiden! It was a failure.

I put on a 2200mAh 3S battery. And the throttle is the max 100%. I threw it out over head. Nose upward. It quickly turned to right and crashed into grass. Main wings was loose. Propeller was broken. Right aileron was partly tore apart. Seems motor or esc was damaged, when giving it throttle, it only clicked and turned a little bit. The whole thing happened very fast, less then half second.

I tried to come up a reason why it turned right! Imbalance of the aileron? No enough up elevator?

I have badly crashed another 850mm Mustang last month. This class of small model is really making me nervous! I know a lot of people succeeded with flying it...

Hi im just useing a 600mw fpv cam with fatshark goggles

[SanExup]

My Fw 190, not true markings for the Dora but I had to.

[SanExup]

jefd36 What are you using for FPV setup? What camera? Goggles or screen?

[jefd36]

This is my new fpv bird wow is it a blast

Hi SanExup

Thanks for the info. If you would, when you get er dialed in post another pict of the CG with the 2200.

Yeah still haven't flown er yet. I was hoping Motion would get back to me about the skid plate. I wrote twice. I know its probably not a big deal but not answering my emails kinda made me a bit skittish about their customer service. Even if they said they wouldn't send me one at least they would have acknowledge my inquiries. I was gonna ask them to put one in the Lippisch p15 I was goin to buy but since I didn't hear a word from them I went another route. Oh well guess I'll put some packing tape on er.

I haven't been able to fly much since the beginning of the winter so I want to get some stick time before I even try the Dora.

Sending PM

Glad you got er figured out. What battery are you using? I have an admiral 3s 2200. If you used this battery can you give me the cg or take a pict of the battery in the plane. Kinda nervous about this one. Never flew anything like it before. I would like to get the first toss without smacking the plane up. LOL My Dora is still on the build stand. Just haven't gotten her out yet. I thought they said to take the motor brake off. The theory being it will be able to move as it touched the ground to prevent prop breakage. Idono again no exp yet.
Hey spent some time around Jackson. Mostly in Victor. Only in the summer months. My daughter and son in law ski there on both sides of the mountain. Anyway beautiful country in Idaho and Wyoming.

Thumbs, I flew the Dora again today, both 3s 2200 and the 4s 2500. After my flights i am thinking I will probably get another 3s pack. I already have a few 4s. The 4s is powerful and fast but so is the 3s, sort of. An indication of the difference is the 4s is fast in vertical flight where the 3s maybe falls off, either way both are fun. I just see myself doing warm up flights on the 3s to shake the butterflies. I will try to post a photo of where I have the pack. I'm terms of CG, I think I have it where it should be, maybe a touch forward. But I check it, inverted, on the perpendicular panel line just aft of the black exhaust paint. Check my photo. I was wrong with my forward pen mark but you can see the second mark lines up with the battery. I've done 4 flights with it there. I think this is correct, maybe a touch nose heavy. I am not totally trimmed out on my elevator yet, it's been windy for both days of flying so I am close to thumbs off but not quite. I still hold a little back pressure. I don't always have the balls to trim in flight when it's a little gusty. And I probably need to put the fun aside for one battery pack and just focus on getting a good trim at cruising speed. Maybe someone else will chime in on where they have their CG.

Hand launching is not that bad. I go 60% to 70% throttle and hold a touch of up and a touch of right. And like I said earlier, I'm getting on the throttle quick while leveling the nose and correcting a little to the right with the torque. It does practically fly out of your hand. I have to remind myself, it's meant to fly and more muscle will only go another foot before the stall of you don't have power. I underhand with my left hand.

I love this plane. I probably will get another one down the road and add a rudder. But I will likely get the P51 or the 1100 Fw 190, and have rudder, flaps, and gear. I'm not sure yet. I like the simplicity of not having things that can get torn off with rough ground. I didn't get the plastic belly protection in mind either and the dirt is tearing up the yellow area at the nose. I threw some clear packing tape on it tonight, we'll see how that works. I left the brake off and didn't break a prop today. I'm pretty sure if you bring a spare with you to fly you won't break one. If you don't, you're sure to break it getting out of the truck.

My wife and I live in Jackson currently, she teaches skiing here in the winter. And I try my best to skip work for snowboarding and sledding as much as I can. Though I have been building us a house in Victor with the intent on moving. Jackson was quiet 20 years ago. I can't really complain, but then again... the traffic is insane in the summer. Two arteries to the heart of town and they are always clogged. And I have obviously started getting back into flying again and the land is flatter and more open in Idaho. I ride a couple of motos too, which Idaho has more to offer there as well.

Get your Dora flying! You won't be disappointed. I did paint my wingtips yellow thinking it would help to see it. They look cool streaking by but do nothing to help with orientation. I like the small size, it'll live in my truck all summer but it is hard to keep it straight in air visually sometimes. I'm interested to hear how it goes for you. I used to fly a lot but hadn't in years, so some things are a little new to me but I have a couple of planes and feel like I'm understanding more as the days go by. Thanks Coronavirus! Nothing like a quarantine to justify messing with rc planes!

Hello, I got around to flying my Dora this weekend. Two flights, two broken props.Well, I wouldn't call the first one a flight, it was a pathetic underhand toss to a stall and drop but in hindsight I am glad I didn't get it into the air. The flying zone I chose would have been a face full of tree branches for the Dora considering how much ground it covers and how quick. A parkflyer she is not. At least not for the first flight. It's true as everyone says, the prop that it came with is brittle. Handlaunches aren't that bad at all, over 60% throttle with slight up ele and slight right, and get your thumb to the throttle quick and juice it. My second flight consisted of handlaunch to wild wing wagging, barely landing it, turning down the gyro gains a little, handlaunch again, flying and trimming. And amazement at how well she flew. Rolls to loops to a immelman. To low level flying at around 50% throttle or less. I landed, checked the battery, 40% so I launched it again. Once you feel confident that it is an airplane, the handlaunch is not a big deal. Not mad throttle but not 50% either, get it in the air and give it throttle and be prepared to lightly bank to the right to compensate.

However, at the end of my second flight i did break an APC prop as well. I am wondering if anyone does fly with the esc brake on? I like belly skid planes because of the simplicity and not having to fix landing gear all of the time. I live in Wyoming and don't have access to a flying field close by, so I have to land on dirt or grass. The tall grass is what broke my APC prop, why I didn't go for the sandy dirt 3' to the right of the tall grass i don't know, first date jitters most likely. The Dora glides really well. Twice I set up for landing at my feet but it flares forever. I love this plane. It looks and flies amazingly well.

The low rates that they recommend are probably what I will program as my high rates and reduce those a little for my true low rates. I have expo mixed in but the high rates were excessive, maybe just me. The low rates were plenty fast enough, it rolls like a windmill. Again I love this plane. It's everything I hoped it would be. Once trimmed and the CG correct, it was on rails. It felt really good flying at eye level, not that scary. A rudder would help but other than low flight and knife edge, it doesn't fly like it's lacking anything.

A quick note, you do have to program the esc to get it to work out of the box. Maybe not everyone, but I did. And I had to reverse my ailerons in my dx6e transmitter, and reverse the elevator on the admiral gyro. But if you watch all of the great videos, for the plane and the esc and the gyro, as you're setting it up, it will save on some time. The only thing I wish motionrc would show is the cg. I was very doubtful that I had the correct cg. Why make me guess? Doo I invert it, or do they mean inverted? For a.$120 plane, that already looks amazing and scale, just mold the damn cg in. Make the marks look like the fuel cover o r something. A panel line is really close to the cg but it will still leave you second guessing. The plane flies amazingly well once balanced, take that first date uncertainty out of the equation and let us focus on keeping our hands steady for the proud first launch. Just my two cents.

Again, anyone flying with the prop brake on? Or other recommendations? I don't want to be buying props by the dozen. I love this plane and want the relationship to last!

I fly it with the brake off. Just make sure you get her nice and slow when you are landing. The Dora can slow to a snails pace

[paladin]

while I don't have this one I flew 704 scale combat for years. you should have the break off so that the prop is free to move out of the way.

Ha funny you should ask. You got lucky you got a skid plate I did not. I wrote twice about it but I never got a response. Kinda disappointed. The plane looks great though.

[James]

What did you folks use to glue on the plastic landing protection?

Hey Bighi . Just used your standard foam tac. I forget if the Dora has included glue if so use that
