Ok guys. I know the lights are going dim here in a couple months but before that happens, I'd like to get some opinions on the current Diabolos.

I've been flying (and loving) Logos for 8 years. While I still love how they fly, I feel like trying something different.

My style is about 50/50 medium 3D and big air.

I like floaty but not too floaty. As an example, I like 560 blades on the Logo 500 and 623 blades on the Logo 600.

I thought about the TDR but I would prefer using 12s stick packs on a tray vs 2 separately mounted 6s packs. I'm also not crazy about the newer linear servo design.

Which brings me to my question. If I was going to buy 1 Diabolo, what would be similar in disc loading and general flight characteristics?

Diabolo 550, Diabolo 700 standard, or Diabolo 700 black edition?

I think I'm leaning towards the 700 Black edition but wanted to get some input.

Thanks!

Owning both a TDR and Diablo 700, they are both fantastic machines,performing very well. I have my Diablo on 14s, while the TDR is on 12s. I'm no stick banger just toot around and have a good time. I love the black edition and would love to have one but I'm very happy with the standard version. A buddy at my field, that I trust, loves both birds and he's a stick banger. I hope this somewhat helps...

Going Diabolo you will love the flying. I'd go BE just to keep with the times. You might also consider the Light Edition. Having said that I'm flying a regular 700 and I use the pack weight and blade size to control floatiness. I've been flying 12S4400 to get lower rpm and lighter feel and 14S4400 for higher rpm with the same pinion and 710 blades.

Thanks guys!

Here's the thing... I'm not a hard 3D pilot but I fly like one. Meaning, while I can fly soft and smooth, I like to use lots of collective, pitch and rudder so I like to lean towards the over-built side.

The original Logo 600SE was built for very smooth flight and I was constantly stripping one-way gears and the main shaft collar was constantly shifting from my hard collective. I have now shortened it to standard 600 length and the one-way and collar have been fine.

The other thing is, I really prefer light helis and since my Logo 700 seems about the same weight as a 700 Diabolo (5.5kg) I'd rather not have the two at about the same weight.

Therefore, I'm leaning towards the Diabolo L to keep it lighter.

I'm just worried I might have gear/one-way/other issues with the L edition.

Do you think the L version will hold up to very hard 3D (and not have Logo 600SE type issues) or should I just go black edition and try to build it as light at possible?

Power would likely be 12s 5000.

As robust as the Diabolo is, I doubt you'll have any issues stripping gears or anything.

Thanks Demetrius.

I'm still leaning towards the L but I just found out that it comes with a rubber band mechanism belt tensioner.

I'd rather have the shock absorber tensioner (even at a little weight penalty) so I plan to order the shock and use it in place of the rubber band on the L.

Just a quick note on the shock absorber. The rubber band version is used to good effect on the Diabolo Speed. I assume that's for space reasons. So unless it's for ascetics there probably isn't a need to switch.

I'm thinking the rubber band was used to keep the L as lightweight as possible.

From what I understand, either the shock or rubber band can be used on the L.

If not, it will make my decision harder.

Personally, I'd just prefer the shock on the L and just take the slight weight increase.

The other model that I'm now interested in is the 600. I don't like the stubby canopy though so I'd be ordering the long/traditional shape if I went with the 600.

I will be examining them all up close and personal at IRCHA. After that, I'm sure my decision will be made.

Ok so I'm 99.999% decided.

This is what my build-spec looks like so far:

-Diabolo L 700 kit
-17t motor pinion
-Scorpion 4035-560
-VTX 697
-Rail/VTX/Rotortech 106/107 tails
-V-Bar NEO
-Pulse or Gens Ace or Optipower 12s 4400mAh

HS: 1200/1600/1900

I will probably fly 70% of the time at 1900, 20% at 1600 and 10% at 1200

Therefore, I'm not really intending this to be mostly low headspeed. I've never flown a Diabolo though so that could change.

What do you guys think?

Quite frankly you do no need to turn the head speed that fast to get performance out of the Diabolo, unless you like 3D smacking.

Also, I would go with the HKII-4525-520 and a 18t pinion, and that will give you lots of RPM range and torque. It is a more efficient motor too.

I fly mine mostly around 1600 and love it, and get longer flights.

My style is also mild 3D and big air.

Thanks Santiago.

Sorry I didn't see you at IRCHA. I met you there back in '10 or '11 while watching some speed runs. Haven't been back since then.

The thing about the motor is, I got it from the Scorpion raffle at IRCHA and even though it's brand new in the box, I don't think they would swap it for the 5425-520, however I was thinking a lower KV would be better.

If you think it would be that much better, I can ask.

I think there's a good chance I'm going to prefer a HS lower than 1900 myself. I just thought I'd rather aim for 1900 since that's where I liked my lightweight Logo 600SE swinging 693's.

Thoughts?

Given the Logo 600 SE is going to most likely be a fair bit lighter, I'd go with 710 blades. Not sure about the motor though. I agree with Santiago re the 4525 as a go to motor if not the 4530. I run a rewound Pyro 800 myself I've read the 4035 used to be the go to for 700's so you could give it a try and let us know.

I just put a set of the NHP Agressor 742mm and let me tell you.... I'm falling in love with this heli, more and more. Big is awesome with those blades. I put the GPS module on it and my Vcontrol read 89 miles per hour and I'm running 13° of pitch. I'm bumping my head speed up with a 22t pinion, so my bank 3 can be screaming but bank 1&2 is mild.

Thanks guys. My style isn't really "3D Smacking", but I consider it fairly hard so I tend to build for medium 3D.

In addition, my plans have changed slightly.

I just noticed that the Diabolo "L" does not come with the battery tray system (and cannot use one).

I've used rubber bands to secure by batteries before and I do NOT want to go back to that. I also want a very lightweight Diabolo 700.

Therefore, I've now decided to wait for the 700 version of the 600 that just came out. Chuck told me at IRCHA that they are coming out with just such a model next.

It has also been said that I could buy the 600 and just stretch it with the 700 boom. I'm not planning on buying this until next spring though so I should be able to wait for the official 700 kit.

That being the case, I'm not sure if 12s 4400 packs will be best so I'll be watching to see what others use.

As for the new 4035-560 Scorpion, I'll either try it to see how it performs or try to swap it for a 4525.

I actually have an Xnova XTS 4525/2Y-530 on my Logo 700. I suppose that, or the 4530/4+5YY-525 would be a good alternative as well.

So for now, it's:

-Diabolo 700 V2 Kit
-VBar NEO

Everything else seems up in the air.

Dave,

Sorry I missed you, I was in site 5 (North) running the Speed Cup there this year Wed-Thu-Fri.

The 4035-560 will be fine with the 18t pinion, even with the 17t.

I would also favor the longer blades if you have them, (710-720) but the machine performs well with 690s too. I really like the feel of the 740s at 1400rpm, it sounds like a big rig but still agile like a 700.

The Diabolo allows to choose any combination you like. Get ready to fall in love with all of them

Santiago, thanks.

I was hoping I would be ok with that 4035-560 motor. That said, I consider my upcoming Diabolo to be my "crown jewel" built to the best specs so if I can use a better motor, I probably will. My 2 top priorities are 1) run cool, and 2) good flight time but not at the expense of power. A hard combo, I know.

I really like the new VTX 717's on my Logo so I'm pretty sure it will either be them or the 697's

I'm getting ready to rebuild my Logo 700 after a bad crash. As soon as that's done, I will start focusing on the new Diabolo again.

I plan to make IRCHA next year so I will make sure I come visit you at the speed trials.

Maybe I'll even try a couple runs even though I've never done it and my Diabolo won't be built for speed. It would be fun to see how fast I can fly it.
