Simple Cub... With a TWIST

[PoorManRC]

Back. Full throttle is pretty powerful on my plane, maybe overpowered for its size. I have to give it some altitude and line it up good for straight shots,cause it's fast and it gets touchier as the velocity of air over the control surfaces grows. Good thing is it's got a great speed envelope so I could fly it in a gym if I stuck to slow high alpha. Your Cub should be much more of a no brainer to keep in the air, but still quite agile and capable of some basic aerobatics. I'm not sure what throttle you want to launch at for the Cub but if I don't have to crank a plane to full to get it to launch I generally don't.

......... I'm doing the slow, dramatic Throttle Up, for a SCALE looking Takeoff! 😉

You've seen my trick of sanding all the Leading Edges round and smooth, then "painting" them with White Gorilla Glue to add rigidity, right?

In my case (so far), it's been purely aesthetic...
In YOUR case, it might add high speed stability, by eliminating the Turbulence caused by those FLAT or even CONCAVE L.E.s.....
Might at least be worth a try! 😉

I'm going to go FLY NOW!!! 😲

Best of luck! And maybe I will give that technique a try on my leading edges some time. What you are saying makes absolute sense.

Good luck my friend, can't wait to see it. The build up is worse then a horror movie lol

I generally fly at 1/2 to 2/3 throttle on most of my planes...Cub included.

Lol, not me, I'm full throttle till my pack has expired then I come in to land ha ha.
On my high altitude flights I cut the throttle at near empty whilst very high and glide but I will reserve a very small amount in case of needing power to make the last bit back because of headwinds or if I miss judge my decent and need a more foe a go around but generally I get it right first time as I know my flying area to an altitude of just over a mile up

 

[Steve Fox]

Do we have a test flight yet?

Heres one of todays flights, i reached an altitude of just over a mile at the highest point but the clouds were very high today and strong winds also kept the clouds running from me and then i had to give up else id never have made it home as although it does not look that far, i was 2 miles out at one point as well as 1 mile up lol

 

[Vimana89]

Really hope the wait is because that Cub flew to the moon and is on the way back.

Plane sponsored by Viagra... all the way up bro. Nice work

My ft cubs get flown in ways Josh Bixler never intended lol.
I am the only one on YouTube flying the ft cub like this, I'm really surprised.

 

[BATTLEAXE]

Thats some sweet footage man. How do u get that kinda range

 

[PoorManRC]

Well......
The few who were SURE it would end up in disaster, weren't disappointed. 😖😭

To all of you rooting, thank you, I really appreciate it!
I started with Taxi problems... When I'd turn left or right, it would just keep TURNING regardless of input!!
MY FAULT #1, for being so insistent on a Flight TODAY, that I kept pressing on.

Kept trying to control her on the Ground, same issue. Except that time, in a perpetual left turn, it hit a Fence, and the Tape ripped on the Power Pod!

MY FAULT #2 SHOULD have gone Home THEN.

Then, the LANYARD STRAP BROKE!!! 😖
MY FAULT #3 - Should have went back to BED!

THEN, I just said "F**K IT!" I'm going for it!
Took off beautifully, flew smooth as silk!
THEN, I made a left turn, and she kept going left, until she rolled and DIVED into the Ground!! 💔😠😭

Cindi didn't know I was actually flying already, and had the Camera in her POCKET.
I have Video of the Taxi calamity... Might post it later.

MY FAULT #4! I had more than enough Power and Thrust. But I listened - and REMOVED the Wood internal Bracing, that supported the Power Pod!
Control issue notwithstanding - IT WOULD HAVE EASILY FLOWN AT 940g!!!!!

Still would have Crashed. SOMETHING was locking the Rudder. But I MIGHT have had a PLANE afterwards!!
The damage is MUCH worse inside...

The ONLY Silver Lining.....

 

[Grifflyer]

Damage doesn't look too bad, might be able to chop the nose and re-build. At least you got a short flight on it...

I'm running 2w amplifiers on both the antenna lines of my transmitter and on my diversity fpv reciever I'm running a Omni for close range and a directional antenna for the long range/ high altitude stuff and my vtx on the plane is 800mw

My range is pretty decent and the 2.4ghz amplifiers were well with the money

I use turbowing amps, the others are fragile and also not the advertised power, I had other amps and they sucked hard.
Here's the amps I use, the specs on the page say 1w but the instructions what come with them say 2w:

That's a weird sounding issue. If it was thrust angle or trim related, it wouldn't "keep going" a certain direction if you bring the stick back to center or reverse the throw. Don't know what to tell you about that.

Thanks....😉 I'm considering it.
When I'm less Butthurt, I'll give it a thorough debrief and damage assessment.
I'm satisfied with the Wing Root and Aft Fuselage reinforcement. Not a SCRATCH from the Windshield back!

Do I feel bad about all the finishing and details? NOPE. It's just how I do things.....

 

[OliverW]

My cub looked the exact same. I just cut off the nose and built a new one. I just need to remaiden it.

That damage is easily fixed, I'd have that back in the air the next day.

Never been a fan of transmitter neck straps, I have one but I find it restrictive and it also causes neck ache so I just hold my tx

Weight IS critical, it's not just about how much thrust your motor produces but also the lift the wing generates.

1kg is really pushing it weight wise and when I'm flying that heavy it's very noticeable.

It does not matter how much bracing you have, hit a metal pole and your gonna do damage, it's better to be light than overweight.

You have two options, pull the nose straight and re glue it or chop the nose off and bond a new one on, I do both depending on the level of damage.

It's a VERY weird issue....
I THINK it will either end up being a defective Servo, binding in the Pushrod, or maybe the Rudder was too soft , with the only control under the big cutout at the smallest portion, with the highest leverage....

I'm in a REALLY bad mood! This, and being Threadjacked, makes me just want to step away from this.
I'm going to concentrate on the Scout and Storch, then come back to this....
THANKS for all your support!

Don't put it off. You can have that airworthy again tomorrow!

look at the pics I posted, it's not hard to replace the nose and I've done it a few times, the tail part of my fuse is also glued on my current daily flyer , I tore it off the plane before the horizontal stab and it was hanging by the pushrods ha ha.

My wing has patches where I've cut out damage and bonded in sections of foam, the poor thing has been abused like crazy but I know I can repair it easily and so take risks.

The first damage on a new build is gutting but now it's happened you can rebuild the damaged part and fly without fear.

The behaviour you stated the plane exhibited is not normal for the ft cub, something was wrong , figure it out and it will fly well, I'd also consider hand launching it and if you have access to that grassy area, loose the landing gear and belley land it.

anything can be fixed

Looks fixable.

I must have missed something though. Who threadjacked you? Just curious.

I love ball parks.

I hate chain link fence, steel reinforced concrete, and metal bleachers.

All of which do weird things to radio and horrid things to motors, props, wings, cameras, and ESCs.

Outfield is a cool place to fly. Infield, not so much. At least not when you are learning, IMO.

Bummer about the foam, but how are the electronics?

Assuming the electronics are sound, YOU CAN FIX THIS. You built this. You can totally fix this.

When you do, before you maiden the plane, test the flight control directions and film that test so we can see both the control surfaces and the movement of the sticks. Then film the balance and show the CG with the lipo in place.

I'm bettin' you had a reversed rudder today or a tail heavy plane.
