New Logo 690SX!!

So of course you could fly it with 690 blades and a pyro 700-52 on 12S

It's only odd gearing if you want to use a big pinion to prevent gear strips. then you would drop down in KV. The stock bundle comes with a 15 tooth pinion and a stronger

Regarding the weight of a more powerful motor, That's why I went pyro 750... Only 1.6 oz more than a pyro 700, and I don't want crazy stupid power,

I am looking forward to it... I am upgrading a 600SE, which was fun but has been hanging on the wall for a couple of years.

I did the same with an old logo 500, upgrading to 500 SX... wAY happier with that than I was with the 500

I hope you enjoy your 690SX.

The results will speak for themselves. I imagine all but the most aggresive pilots will be perfectly happy with the 690SX and that is the vast majority of us.

I was running my 550SX at only 1900 and 2170 yesterday, so it is unlikely that I would be pushing the limits of a heli like this either.

If the 690SX is as well balanced as my 550SX is then it will be a winner because people will enjoy flying it whatever the motor is.

I love my TDR, but will admit it is not balanced as well as my 550SX is, and in some ways I'd compare Mikado to Lotus's world renown suspension work. They just get all the geometry right.

Sorry to hear that, did it catch fire or just shut down and what esc ?

Maiden flight was about 10 seconds when smoke came out from the canopy. Esc is Scorpion 120a. The esc is not burned but can't turn a motor anymore.

It's not my heli. We've got a Helijive in there and for this first testflight we set it to about 1750 RPM.

Hi guys
If you use the carbon fiber boom do you have to use the static kit?

[prototype3a]

Yes.

[M52 POWER!]

Is it possible for me to convert my 600SX to 690SX or is it a major change?

[taosgraveyard]

pretty major

different:
head, canopy, tail boom, tail boom supports, tail control rod
counter bearing and motor (if you want the 15T pinion for robustness),

additional stuff to get:
- battery support at front of frame and the platform under the frame

and probably stuff i forgot.

cheaper than buying a kit - yes. especially if you sell the stuff you don't need

i am upgrading my 2010 600 SE, for which the list is even longer.

[alexf1852]

How about going the opposite direction? Buy the 690SX and the parts to convert it to a 600. Seems like only the tail boom and support, belt, tail servo control rod. Am I missing anything? I would be using 630 blades with the 5mm bolt hole.

Why? The 600sx is already more than capable of running the 630's with no issue. Why add the extra weight to a 600 size heli. One of the things that makes a Logo fly like a Logo is the light weight.

[prototype3a]

I suspect he meant the drivetrain components. I've had the same sort of thought and wonder when/if Mikado will update the 600 to use the new double oneway unit.

I used to own a Logo 600 3D a couple of years ago and sold it. I know how light it is. It's one of the things I really liked about it. But there were other things that I didn't like about it.

But I feel myself gravitating back to a 600SX. But one of the things I like about the 690SX is the bigger canopy and battery support that would be perfect for some 4500mah packs that I have. I also have a lot of 3600 to 3800mah packs. Larger packs than the normal 3300mah. Hence my thoughts to use 630 blades that have the 5mm bolt hole.

One of my 600SX has Rotortech 640 mains with Rail 116 tails. There's plenty of clearance but I'm using the longer main shaft for the 600SE. Running 2260rpm with 12s 3800mAh. When I do hard reversals I can hear the belt under strain. I would welcome a belt and pulley upgrade like the 690SX for the 600SX. I will try the bigger canopy too but if/when they release it in the XXtreme Red/Yellow colour scheme.

A new belt and rear pulley would need to be created for this to work. Either that or a new front pulley with the original tooth profile, as the 690SX is a different design.

[mahbouni]

I would have thought that everything on 690SX can be retrofitted to the 600SX, but if you want to keep the 600SX boom then you would need a shorter version of the 690SX belt as it has a different tooth profile.

[taosgraveyard]

You are correct. Everything can be retrofitted. If someone finds a belt with the new tooth profile that is the right size that would a great thing.

Anyone tried building the 690SX with the MKS X8's yet?
A little bit of overkill, but I've got a set available I stripped from another build and figure why not?
They should fit I guess, just the metal horns instead of the mikado carbons will bother me a bit.

[KevinB]

X8 servos are what I have in my 690sx. They work great!
Waiting for the 690 to become available, I originally had it's electronics in my 550se. X8 servos all around, heatsinked 160amp YGE ESC, 18a WR BEC........now THAT'S overkill !

Definitely overkill!

BLS 451's do a great job are lighter and use a lot less current.

But whatever floats your boat!!!!!!

TBH, I had 451 and I wouldn't put them in any heli ever again. They're just too slow and too weak...

451's don't have flashy specs. but they do fly well and are a affordable high quality servo. pretty good one to use with a BEC. I have them on my TDR and on a logo 600. both heli's fly excellent.
