11T too small I think. Evrytime overkill the main gear about 10 start. The 12T no this problem

When the 11T kill.

When the outside temperature is <20celsius everything great work !!

Kontronik recommend >80% really, so either go 11T or higher RPM/lower pitch with 12T...

Make sure alignment is 10000000% perfect, I mean it, a little off and with these type of watts we are pulling, you strip a maingear in no-time.

I fly 11T..

You write this.

106T main, 12T pinion, 12s1p 5000 packs, 77% throttle, about 1935RPM at hover.

therefore I changed 11T to 12T.

I found that the scorpion were running quite hot and making the gears strip easily (now i run kontronik and no gear wear), you need to have a little backlash in the tightest spot.
Use some grease on the gear also.

The lower peak amp draw leads me to believe this motor might be more gentle on lipos. This could equate to longer cycle life. I'm wondering if it would make sense to push 620's on 12s with this motor over say, the 4035-500kv.

Logo 600 SE is in the building
The "happy truck" came today, and gave me a Logo 600 SE full kit.

To speed-up the experience, I used the boom, boom supports, tail control rod and belt from the kit to "convert" one of our existing Logo 600's. I'll build the full kit ASAP though. No such thing as too many helis, right ?

Ready to fly with Scorpion 5020-450, Thunder Power 2X5S 5000 mah 45C battery, Jive 120, Edge 693 mains and Edge 105 tails with canopy on is 9 pounds 9 ounces (4.34 kg). CG balance is almost perfect with the packs all the way back in the frames.

Unbelievably light for a "700" size heli. Waiting for Kyle to get home from school to take it out for a test drive .

Good to hear Mr. Dahl

One question, what are the differences between a 600 and 600se besides the tail section?

And glad to know that Kyle finds school the most important.

Long,

Nothing. The SE has a longer boom, longer boom supports, longer tail control rod, and longer new style belt.

Oh yea, and the cool looking red canopy .

But with those small changes, it opens-up a whole bunch of new possibilities (-:

For those interested, we’ve managed to get some flying done with our new Logo 600 SE over the past two days. See the set-up posted earlier in this thread.

Since the “Logo 600 stretch” is not a new idea, most of what I’ll say probably has been covered by those already flying them. But this is the first time Kyle has never had one in his hands.

When comparing the standard Logo 600 and the SE, other than the words “Logo 600” in their names, the similarities stop there. They are two different helis in flight characteristics, each having their own unique qualities.

Some stats: Air temp. was 80 degrees F (27 degrees C) on both days, wind was 10-15 mph (16-25 kph) (which was good as we were able to assess the model in a little wind). Motor temp. averaged (with Kyle doing 3D work) 138 degrees F (59C), and ESC 100 degrees F (38C).

Over a two day period we tried 13, 14 and 15 tooth pinions, collective pitch ranges between +/- 10 to 14 degrees, and head speeds 1800, 1900 and 2000.

We never flew longer than 6.5 minutes, but never shorter than 5 minutes. I can’t say specifically how much time you could get for any particular flying style / head speed combination, as Kyle would mix styles during all the flights, and we adjusted the flight time “on the fly” based on what he was doing with the heli during each flight. However, we never used more than 75% of a 5000 mah pack’s capacity on any flight. I’ll conclude that if you ran 1800 head speed and cruised around doing forward flight aerobatics and light 3D, you could get longer then 6.5 minute flights for sure.

Rather than a flight-by-flight report (take forever…this is long enough already), here’s the deal: the “sweet spot” for Kyle with the set-up was on a 14 tooth pinion, 11.5 degrees collective pitch @ 1900 head speed. 14 degrees of collective pitch is too much for the power system to reasonably maintain its head speed. Using a head tack and observing the heli during 3D maneuvers, we lowered the pitch to 12 degrees, then 11 degrees, and then settled on 11.5 degrees as the threshold between the most pitch you can use and still have the head speed stay reasonable constant through tough 3D maneuvers. The heli is very capable for sure with these numbers.

It’s all about what feels right for each pilot however. Kyle felt 1800 on a 13 tooth was too timid for him, but the heli was still fully 3D capable, yet had a more mild feeling to it…and would of course produce longer flights.

2000 head speed on a 15 tooth was over the limit for our machine. We established the “over the limit” threshold by putting in a flight with 14 degrees of collective pitch at 2000 head speed, and Kyle hammered the heli hard for the whole flight. Our set-up includes the 5020 motor (which is no lightweight), and 5000 mah packs, so it’s on the “heavy” side as this model goes I’m told (if you want to call a 9 ½ pound 700 class heli “heavy”). After the flight a close inspection of the head dampners (we were warned about this so knew where to look), showed signs of the small black washer between the o-rings and inside blade grip radial bearing, starting to cut into the o-ring. There was a small sliver of rubber in one of the gaps between the head and the grip. That was the last flight of the day. On disassembly later that night, the dampners showed signs they didn’t much like that kind of abuse. However, the dampners already had over 50 flights of hard 3D flying on them prior to the test. But still, we find no reason to go into that flight regime, as the heli flies great and is very capable using more conservative numbers.

In summary:

The thing Kyle disliked most about the SE, was due to the large disc size and the relative lightness of the machine, in maneuvers where the disc was vertical and with the wind blowing, the disc was kind of like a sail being blown in the wind. You have to correct more to maintain your position relative to a fixed point on the ground as compared to a standard Logo 600. Other than that, no bad tendencies at all. Flies like a dream.

The thing Kyle liked best was a result as well of the larger disc and light weight. The heli will stop on a dime. As an example: while performing a forward flip to a stop and reverse from high speed forward flight, the momentum of the standard Logo 600 requires a certain amount of patience for the heli to slow down during the flip, and using negative collective, get it going in the opposite direction. The SE on the other hand, once you flip it forward and present that large disc to the on-coming airflow, it stops “right now”.

Also, it will hang in an auto forever, and ever, and ever…(-:

One last note: Although we will “fine tune” the V-Bar settings for the SE as we go, looking for subtle improvements where possible, other than the changes to the collective range and lowering “pitch pump” down from 25 to 10, the SE was flown with the exact same V-Bar settings as Kyle uses with his standard 600’s. There was no “pressing need” to change anything for it to fly really well.

Was he using edge 690 flybarless blades? Mr Mel previously stated that for his logo 600 SE conversion he really like the radix blades, but on the normal 600 he liked stiffer blades such as the edge or other brand.

Did you try turning the integral up from 45 to 55 on the main rotor?

Not exactly, right on the Radix on the 690, but Edge is virtually the same as Radix so I do NOT like those on the L600

But that's me, Blades are totally PERSONAL in what you like, there is no right or wrong.

No. Did not see an immediate need to. Not to say things can't get better, but it flew pretty nice with the standard Logo 600 default
parameters in the main rotor's expert menu.
