Tail Heavy Planes Fly More Than Once (HobbyKing/Arrows Corsair 1100mm Maiden Flight)

[@buddy1065]

Admire your courage. No way would I have flown a buddy's plane without confirmation of the CG. Thanks for sharing.

Awesome flying to get that girl on the ground in one piece, it looked like a pissed off bucking bronco!

[@stardustsparklin4867]

Any maiden where the aircraft is still flyable after is a success in my book. Great job Jon! I've found my war birds like a long take off, roll out, and approach. Much easier to control and looks more scale. In the air I'm an angry bird, but on or nearing the ground I pretend I'm driving Ms. Daisy sipping a hot cup of tea. Lol!

[@TwoBrosRC]

That's the way to do it buddy.

[@LiftVector]

Impressive skills bringing that wild girl back in. Cheers man!

[@ltfadl1]

Very nice flight. I'm sure he was happy to see it in the air finally and that was nice of you to get it going for him, that's awesome. I'm so glad it didn't do much damage when it went into the tree. If that was me and my luck the prop would've gone south lol Love the Corsair, they fly great but will get ya in the air, I have the 750mm HK and it has 2 4oz weights in the nose plus I have to shove my 3s battery all the way up in the nose so they are just designed like that full scale due to the engine weight up front possibly.

[@TwoBrosRC]

Most likely, that sounds right to us.

[@ryanyoung54]

Nice work!

[@ArthurRC]

Wooooow very nice safe !!!!! That’s Tail heavy 😅 and with a good pilot it can fly more than ONE 🤣

[@LoveRC]

OMG that was crazy!!

[@dogfoodking]

Nice to see the taxiway getting some much needed love! Oof with the takeoff...

[@cwwisk]

Absolutely! All 3d planes need to be tail-heavy.

[@TwoBrosRC]

At least somewhat anyhow.

[@cwwisk]

@@TwoBrosRC neutral to slightly tail-heavy is usually still controllable with 45 degree deflections of large surfaces you'd find on racing or 3D planes. You can get some really flippy floppy rolling loop tumbles that way.

[@kleinbottled79]

Martin Pickering claims the opposite, but maybe that only applies to 3d jets or madlads like himself or something. I really wouldn't know. My Ultrix 600 seems to 3d best with as nuetral a balance as possible, but I'm a noob so /shrug. School me internet, I wanna learn.

[@cwwisk]

@@kleinbottled79 a tail-heavy jet with thrust vectoring will not behave as well as a neutral or forward CG. Think about it this way: the CG is the fulcrum of the yaw, pitch, and roll. When you have cg behind the center of lift (wings) the fulcrum of rotation, the wings have to travel through the air in a way which produces more drag. The flat top or bottom of the wing winds up resisting the roll, pitch, or yaw being input from the nozzles. The more wing surface in front of the CG, the less effective the thrust vectoring will be. However a Slick 540, for example, with the CG around the center of the main wing root chord will be effectively tail-heavy because the symmetrical airfoil creates lift in front of the CG, but the CG acting as a fulcrum induces the least drag at the center of the wing's surface area from front to back if that makes sense. If the wing is swept extremely, then roughly the midpoint between the farthest forward and farthest aft point on the wing would be this point. These types of wings are uncommon for 3d for this reason. The exception is the SU-47. Most 3D planes have a slight wing sweep (usually slightly forward).

[@TwoBrosRC]

@@kleinbottled79 Neutral is usually best, but slightly tail heavy can make for amazing 3D setups.

[@D-Slowpass]

They fly better without the drag from the ordinance and drop tanks too

[@AerospaceMatt]

2:18 Nice shirt!

[@SONICBOOM-117]

If I learned anything about corsairs, they are pitch sensitive. Well done Jon.

[@TwoBrosRC]

Especially when they're tail heavy.

[@gbro8822]

Great job, thank you.

[@fastrack59]

I had the same exact plane. No problems with the CG. But was always hard to take off coz it would torque roll aggressively to the left. So I installed spacers behind the motor mount so the prop faced slightly to the right and down a bit. PERFECT! Never had to use right rudder again on take off. Straight up each and every time. I admire your skills in controlling this twitchy/ unstable little beast! 👍👍👍

[@TwoBrosRC]

We don't mind using rudder for takeoff - it's standard procedure for most taildraggers - but this one just felt super weird.

[@RubyS.1]

I noticed the new eflite model has the the prop facing so far down and do the right it looks bent much more than their other models. Seems you where on to something

[@MrWagner528]

That F22 crash into the pits was brilliant.

[@TwoBrosRC]

Couldn't have done it better if we'd tried.

[@katrinatrafford5104]

Good to finally see those lumps of grass being cleared off your runway. I bet that awful flying someone else’s plane into the bushes hahaha. Glad it worked out though

[@TwoBrosRC]

Definitely didn't feel great, that's for sure.

[@FFE-js2zp]

Corsairs are tough to balance bcs of the main gear swinging backwards. You have to balance them gear up.

[@TwoBrosRC]

There you are. We were wondering what happened to you.

[@calaiscruiser]

I have to agree, I fly a FMS 1700 Corsair V3 and I have found it to be quite CG sensitive. Definitely a gear up CG setup.

[@FFE-js2zp]

@@calaiscruiser Yeah I have one too. Fun airplane. The wing wrists have some stress cracks, but I’ve flown it a million times

[@s9523pink]

I have the FMS 1700mm version 2 of this and just maidened it today, had it sitting for a few years! Bigger is easier to fly than smaller, air molecules don't change size! Also, Corsairs need to be balanced inverted because of the gull wings with gear up. You can find CG for these models online, usually the instructions are conservative. Tell your friend to go bigger, he'll see better and they're more forgiving and appear slower and are less twitchy. Also use expo, especially on the elevators.

[@TwoBrosRC]

We always use expo - usually 40 to 90%, depending on the model and the amount of throws we're using.

[@s9523pink]

@@TwoBrosRC , well you’re right that thing is real responsive!

[@shanehoule9477]

Pretty cool guys. Pluss the helicopters flying over was awsum

[@dungeonaged]

I have the Arrows version, I use a LemonRX Stabilser and its quite nice to fly, the dark color can make it hard to see the orientation, otherwise its a nice flyer. I use a 2700mah 3S battery rather than the recommended 2200mah and I have barely any trim at all.

[@capnhardway]

It did fly very well in the end.

[@velcro62]

Can you tell us more about the spray at 3:30?

[@TwoBrosRC]

It's CA accelerator. It causes the CA glue to cure and harden in a few seconds instead of 30 to 60 seconds.

[@old-rcplane-phart]

@@TwoBrosRC Foam SAFE accelerator. Takes 5 seconds to set instead of immediately like other (wood) accelerator. (I found out the hard way. It works on foam, but will eat some foam compounds)

[@aragorn318]

@@TwoBrosRC Did you use Zap CA and kicker? Mine's not nearly as effective as yours.

[@TwoBrosRC]

@@aragorn318 No, it's BSI medium CA with CA accelerant.

[@kevinbelanger9948]

I have to agree the corsair is one of the great and beautiful planes. Other than the me 262 and p38 lightning. If your quick on the sticks the corsair flys amazingly no matter what make they are. Love flying them. And dont feel bad corsairs like alot of right rudder on take off and nose tippy. But once up they are beautiful things to see flying

[@Airguardian]

How much expo were you running?

[@TwoBrosRC]

50%. Which is good because the tail heavy aspect of the flight would've been almost completely uncontrollable without it.

[@saito125]

That's a Durafly Corsair, I had one years ago. It's one of the best foamie Corsairs out there.

Dude... i can feel the pressure on you all the way in santa rosa ca..... i know o get stressed out in this hobby too, and im not flying someone else's airplane. For what its worth, i think you are an incredible pilot and should be proud of your self. You also have a bad ass youtube channel!

[@TwoBrosRC]

Appreciate you, Patrick!

[@TheFrenchPug]

Man, you could have wrecked that thing again with that balance point. Nice job saving it 👍

[@TwoBrosRC]

Absolutely. You get a feel for how it flies and what thrust (and no thrust) will do in that condition - which is part of the reason why it came down safe. The other reason is that we just got super lucky.

[@TheFrenchPug]

@@TwoBrosRC There is a lot of skill in luck sometimes. You could have plastered that thing too but you didn't.

[@TwoBrosRC]

@@TheFrenchPug Timing the oscillations so that it plopped on the ground instead of smashing into it was the hardest part.

[@TheFrenchPug]

@@TwoBrosRC Definitely. Like balancing a marble on a cocktail table.

[@capnhardway]

I always see the spraying of "activator" what is that exactly?

[@TwoBrosRC]

It hastens the curing time of CA glue to a few seconds instead of 30 to 60 seconds.

[@PhilBender612]

I was waiting for the foam to start melting when you were putting CA on ,😆 could you imagine that? lol it could always be worse. He didnt seem to mind,. I think once you got it up he saw how pitchy that thing was he understood. Those old hobby wing planes left a lot to be desired and usually needed a bit of work to get them to fly. you seem to have done that. Tell him bring it home and hang it back up for another 8 years.

[@TwoBrosRC]

We use foam safe CA glue. It won't melt.

[@charleswinter1335]

My...Bruce is so right, I've been trying to learn how to fly and keep struggling 😫.

[@TwoBrosRC]

It's definitely not the easiest hobby to get into - but with practice you'll make it. Try starting with a durable trainer like an AeroScout and work your way up after mastering the fundamentals.

[@kleinbottled79]

Pica sim is a free RC plane simulator. You might need to buy a cable to connect your radio to your computer, but you might already have it; and some just use a usb-C. There weren't sims when I was learning but I sure wish there were. Working with a Heli sim atm. Few more months of daily practice and maybe I'll actually buy an RC heli. (Those things are fiendishly easy to send into the ground. Make planes feel easy.)

[@old-rcplane-phart]

I would lay cash money the eflite corsair is very close if not exactly the same plane as far as replacement missles go. IF it was me, I would buy them to see & GIVE them to him.

[@TwoBrosRC]

He's taking the missiles off. It's not a big deal - he'll be maidening an experimental full scale STOL aircraft soon that he's a bit more worried about. We'll film the takeoff and landing next month when it takes its inaugural flight.

[@TwoBrosRC]

[@Sabotage_Labs]

Ur killing me smalls! Crashing my all time favorite plane....lol. So yea, as some who held a PPL flying just Cessnas and a RC Geek now... as far as flying dynamics... I tell newbies all the time that it doesn't matter if a plane is 2lbs on 200 tons... the same principles of powered flight apply. Air is air, bornelli's principle does not care. Lift keeps you in the air. Lost of lift equals dirt nap and dollars lol. Now, as far as piloting... there's very little in common. With RC.. you can't feel ANYTHING. That was the first thing I had to grapple with going from a PC Sim pilot to POC in a 172. Flying IRL gets soooooo much harder when you're bouncing around on a hot day in Phoenix and trying to get a class B transition over Sky harbor...lol. Mountain are just black voids of nothingness. Could be a hole in the ground or a 4000' high granite and basalt cloud. I hate those clouds! Fly at 130knts an chop the power and just feel how you slow down. Or, feel stick shudder (in many aircraft type but not all) when you're about to stall! Feel the sluggishness of slow and dirty flight. In RC, You can't feel almost everything! You can't feel floating in ground affect. You never have to look outside the door window during a nasty crosswind landing. Not a natural feeling. And... if you did some of your snap rolls in a real fighter....you'd likely vapor lock your brain and nose dart at 400knts lol. For example... when I was in flight school I had a problem with nose gear steering on the runway and consistent landings. A family friend with 8k hours asked me...what kind of shoes are you wearing? Told him Doc Martin's. He said yea dude... get some soft soul tennis or ball shoes. Sneakers. Even a cheap better can be better so you can feel everything in your feet! Best advise I ever got. Made a huge difference. You can do that with RC. BTW. A Properly configured corsair will fly like a pussy cat. It's why they were so effective in WW2. Well, that and most of Japan's well trained pilots were fish food. Any plane with bad CG will fly like a pig. I love flying the Corsair. And...she's one of the most sexy planes eve built. All the curves like a sexy round woman...lol. that huge nose with all that engine in it. Yea boys... what is that a reminder of...lol. the gull wings like the nap of a beautiful woman's neck! Yea sexy as hell! Now... look at the F35! All kinds of ugly! Like someone with a glandular condition...lol Hip tip... not sure if you know but didn't notice you doing it. With taildraggers, apply full back stick on the ground and especially on taxi. It'll keep down pressure, even from prop wash, on the tail gear. Can help for avoiding ground loop. Can even be used for first few seconds of roll out. But, often people forget to back off and get into bad habits. Just a tip or maybe for beginners. Please don't ever crash a corsair again! Breaks my heart and... reminds me of pile driving dirt napping a couple years ago. Bloody Spektrum! Have fun!

It's clear to see that you had NO rudder in to it when accelerating down the runway. These aren't serious RC Planes, they're just 40 size foamies...

[@TwoBrosRC]

It had rudder input but we made a mistake and let go of the rudder while throttling up.

[@calaiscruiser]

Yikes! he would not have been able to handle that thing.. Personally, I would have removed the ordinance to reduce any unneccasry drag which I'm sure would have helped but yeah that thing looks scary tricky to fly. Typical Hobby King rubbish..

[@neilsaeroadventures1116]

I have a question for everyone. Do you use gyros or safe? If so, why? If not, why not? I'm just curious because I see so many people talking about safe and I only recently learned what it was. Personally not for me but I'm just curious what the overall opinion is.

[@TwoBrosRC]

No gyro on this model - it was flown fully manual, even with how tail heavy it was. We usually fly gyros on everything though - there's no good reason not to that we've seen.

I hate flying other people's planes, but sometimes you have to.

[@scottmonroe6522]

It stopped responding to rudder because you took it out. Watch it again, it drifts left and you give rudder to correct and the airplane stops it’s drift at the left side of the runway and then you quit with the rudder.

[@TwoBrosRC]

Yes, at that point we wanted to focus on getting it up into the air quickly hoping it would prevent it from, well, doing what it did. Mistakes happen, unfortunately.
