A quick unboxing of the Fireball

[toadiscoil]

You sure know how to fly. It was funny I could actually understand since I am from Mexico

How did you find the Thunderbolt blades or is it the same with the Lynx blades?

Per Bert's video today it seems like for what you want out of it a Mini Comet would be better for you.

The Competition motor should help but you again would need a lot of headspeed. The motor just gives you more. With the special motor and lack of pinion you would have to mod a lot to get a regular motor to work.

Excess weight, 200 g more than ox3, it penalizes.
My friends is starting to call it the whale.
The only acceptable way to fly is at 100% rpm
But it lacks stability, and agility by weight. swasplate swings continuously.
I am very insecure with him.
I recorded a video of fireball and oxy 3. You can see the difference.
Has anyone managed to fly like Oxy?
I'm thinking of changing the engine for a lighter one

So- not attacking, or being a naysayer....

But if a hack pilot like myself, and countless pros (yes, I know they a Pro pilots) can fly this well- I have to ask if the lack of performance is tuning related?
Yes, i know its heavy, but a blanket statements of "The only acceptable way to fly is at 100% rpm - it lacks stability, and agility by weight. swasplate swings continuously." just seem pretty far out there when weve seen it fly well.
If you do have it tuned properly, with quality blades and you just dont like how it flies, that's totally inderstandable. Sell 'er and enjoy the Oxy goodness.

And with the weight of this heli,are the non-reinforced 275mm lynx blades a good choice?

IDK, everyone has a different definition of "acceptable way to fly".

To me, videos of pros flying the Fireball made it an undesirable model for me - I see from the videos how heavy it flies.

But that's just me -- I like low disc loading.

P380 vs G380 illustrated that perfectly for me. I like the heavier feel of things- may change as the skills grow thou.

[jrman83]

To me, for anyone to say they may mod to accept regular motor, knowing full well what that would mean just shows a defeated feeling. Surprising, to say the least.

Sorry I disagree you need to leave headroom when flying governed.

The SAB esc is a rebranded hobbywing esc

The hobbywing manual recommends up to 86% throttle when running gov store. So the max throttle % I would flying the Fireball is at 90 %

Of course the motor will bog badly when running 100% throttle in governor mode. There is absolutely no headroom

You need to shoot another video flying the fireball at 90% throttle governed

I did not say that I did not like ... fireball
I love the mechanics of this heli .. but lighter, would be perfect for my.

Still believe that the smaller, plastic blades are contributing to that feeling.

For me as well. I like the lighter feel of the P380 better.

No one is suggesting you don't like the fireball

We just saying perhaps on stock motor you cannot get a high enough governed headspeed to get it to fly similar to the oxy3. If that is the case you need to get the competition motor as it can run 20% higher headspeed.

what governed headspeed did you run on the oxy 3 ?

100% on the fireball with stock motor and esc headspeed is approx. 5000rpm and with competition motor it is around 6000 rpm at 100%

My suggestion is run 4500 governed headspeed on the fireball and 4000 headspeed on oxy 3 with same blades and then compare both helis.

[dl5973]

Bert & Kyle Goblin Fireball - Low HS vs. High HS (11 min 3 sec)

In this video Bert is flying on stock motor at 80%. 80% is 4000 rpm.

85% is 4200 headspeed so I assume 90% is 4400 rpm.

4400 is probably as high as you can go for a good governed headspeed for the fireball on the stock motor.

In the video Kyle is flying the competition motor @ 95% which gives him 6000 rpm.

So that means @90% governed headspeed with competition motor you should get around 5500 rpm

[Smoggie]

Presumably he is running 100% because that's what it takes to get the performance he's looking for.. But as pointed out it's not a good solution because the motor will bog.I think to be fair the Goblin should be flown with the blades supplied in the kit. If for no other reason than to stop people blaming the non-standard blades for the poor performance.

I've banged on about it too much already but 200g is a huge weight penalty to be having to drag around on a heli of this size. It just has to have an effect on performance, even SAB cant change the laws of physics.

Agreed

He would have to run both helis on the SAB 280 blades to compare and work out what headspeed for each heli gives similar performance. It will take him some time. He cannot just fly the fireball a couple of times and say hey it is no where near as good as the oxy 3.

It takes me at least 10 or more flights to tune my helis to how I like them to perform

[Borobilbo]

So... if the SAB280's are the key regarding the flight characteristics... would it mean OXY would fly even better with those ones on it??
Just wondering.

Oxy also flies with plastic blades
I broke the original blades.
I'm waiting for new ones.
The blades do not influence the power of the heli.
Maybe the problem is that I was expecting more of this heli ... I'm not
Going to change the engine, it's too expensive.

What do the official pilot change the motor?

Smaller blades, that flex = less lift and pop On a heavier helicopter.

The main difference is plastic vs. CF. The difference between 280 and 285 will be minimal in comparison, assuming both are CF. The main reason some Oxy pilots are interested in the SAB blades is for the possibility of having one blade for both helis. Since the SAB takes 2.5mm and the Oxy 2mm, this is really only feasible with the SAB blades.

Depending on flying style and skill, some Oxy pilots much prefer CF blades over plastic. The main benefit of plastic is that they're about half the price when you need to replace them.

But as Doom mentioned, they flex a lot more, so they fly differently if you're doing anything much more aggressive than circuits.

[toadiscoil]

To his defense he did fly the Oxy pretty darn good on plastic blades and he was expecting something similar on the 280 (Fireball). The 280 is heavier because of the motor and being 6S by default. But I also agree the best comparison would be a well tuned 280 on Thunderbolts versus the evidently well tuned Oxy 3 to make a fair comparison. Still indeed they are different animals the 280 is a Goblin so requires some high headspeed but is designed to be easy to fix and cheap to repair. As Bert put it the Mini Comet with a lighter body seems to fly actually better.

Tons of pilots with Oxy's that now also have 280's can other pilots put more comparisons together?
