I am going to to running the Logo 500se with the extended boom for my very first Logo I have ever owned. I will be running a 12s setup on the 500. I have a few questions/concerns. My motor will be the scorpion HKIII 4035-560 for sure with a 13T pinion. I will for sure be using the silverline vbar for my FBL system. I will also be using for sure the Kontronik Helijive 120 ESC. My question of what servos to use would be the JR DS8717 on the cyclic with a JR 8900G on the tail or should I use the Savox 2271 on the cyclic and the Savox 2272 on the tail? I will not be running a HV servo or a external battery pack on the servos. I'm on the fence on which one to use here as I think they are both great servos. If someone has any input I would love to hear what they think or have experienced. Also if anyone is running this setup or this heli please let me know anything I should be aware of for this build and stuff that will save me some head aches! Thanks so much!

We have A LOT of experience (and I mean thousands and thousands of flights over the past few years), with running 8717's and 8900G's on the Kontronik Jive 120's default BEC voltage of 5.6V, and can state without a doubt the combination is solid. We used a Western Robotics .8V step-down for the tail servo, and all was well.

Don't get me wrong, I'm not saying the Savox combo is bad, it's just that we have no experience with it.

Now, as for the power combo. The stock Logo 500 gears (Mod .7), are designed to handle 6S systems (which the stock Logo 500 is designed around). A 12S battery and 4035 motor is a Logo 600 power combo (which has stock Mod 1.0 gears). Using the higher power combo on the Logo 500 with stock gears is likely to cause you gear stripping problems.

If you're going to change the gear and pinion to Mod 1.0, then things will be closer to the ball park, but even then, with a 560kv motor on 12S (especially with a 13 tooth pinion) will drive your head speed pretty high (too high really).

I'll assume you're going to run 600mm mains with the "SE"'s extended boom, but understand that a 4035-560kv motor on only 10S with a 12 tooth pinion is a "classic" Logo 600 combo, running @ 2200 head speed. Go 12S and a 13 tooth on that same 560kv motor, and look-out!!!

Thanks so much Dave! I was thinking of running the 8717's more so than the savox's as most of the guys I fly with run JR. I am really excited about this being my first Logo. I want to give it a go with the 12S setup b/c I am running a Trex 550 on a 6s setup. I have a sweet setup on the Trex with all aftermarket parts and electronics but I want something that really slams. I think this Logo will be the answer to this request of wanting a slamming heli. I have Edge 603 blades to run on it. I assume this will be more like a 600 than a 500 with the set up I have. I really don't want to be stripping out gears and having problems so I may consider a 12T pinion if that becomes an issue or possible going to Mod 1.0 gears. I will also look in to a western robotics step down for the tail servo. Once again thanks for your input and I look forward to learning from everyone's experiences. Thanks again Dave!

You say: "...I really don't want to be stripping out gears and having problems..."

And: "...or possible going to Mod 1.0 gears."

And: "...I want to give it a go with the 12S..."

Well, I'll be more blunt. If you go 12S with mod.7 gears, you WILL have problems. Just plan on going with the Mod 1.0 gears from the start, and save yourself the problems you say you don't want to have.

And if you want to "slam" the heli on 12S, you might want to go with the counter bearing as well...and learn all you can about setting the proper gear mesh with the herringbone gears.

Remember the heli was designed some years ago for 10S set-ups. Going 12S and living on the edge with it, requires helping the system hack the 12S where ever and however you can.

Then I will for sure run the mod 1.0 gears upon your recommendation and experience! Once again thanks for your recommendation and I will use it and get a counter bearing as well and check the gear mesh with the herringbone gears!

Along with maingear issue that Dave mentioned I would also add that the 500 has smaller main grips, spindle, and bearings than the 600. The 500SE is great if you want to "slam" on 553s but IMHO is not the heli to do that with 603s and the components you want to run.

I'm going to order some edge 553s as well bc if I don't like the 603 I can run them on my Trex 600n and if I do like the 603 I can run the 553 on my Trex 550. I understand where you're coming from I. The bearings, spindle, and grips it does make sense! Thank you too big fil!

Hi guys

My advice...... Don't reinvent the wheel.

There is so much info on what motor/esc/battery/blade combo to run. Follow the good advice from those that have tried it all.

I could not be happier with my Logo 600 with Kontronik 120hv, Pyro 700-52, Futaba bls252/256 all on 6v and Edge 620/95 blades. It is by far the nicest heli i have owned in my 12 years and +25 different machines.

Regards
Paul

Another Question about batteries
On this motor what batteries would you recommend running 3000mAh, 3300, or something bigger? It will be 12s setup just curious on anyones thoughts!

Edit to the motor listed above
I mistakenly quoted the wrong motor I have an HK 4035-500 not a HKIII 4035-560 motor. Sorry for the wrong information!

4035 + 500se = dumb.

4025-550 on 12s with mod 0.7 will be PLENTY of motor in that heli. Keep to lighter batteries like the 2200ma if you want to slam it around

The grip design comes from the logo 10, a 4s 500mm heli that was good up to 550mm at about 22-2300rpm....any 4025 motor can do that easy, they can also spin 600s at 2000rpm just fine and save 4oz, 2000rpm is plenty of headspeed for a 500se or 600 that weighs under 8lbs with light batteries...

I've already have the motor with the kit! The only thing I have not bought is the electronics! I really don't want to sell the motor at this point! I'd rather try this motor for a bit and see how it works out and if it's too much then I will get rid of the motor! Even though this motor is new I will still have to sell at a used price now or later. With the KV being 500 instead of 560 would I be ok with the mod .7 gears or should I still go with Mod 1 gears? Thanks for the Info on the batteries KC!

ok gotcha, the 4035-500 will definitely work in a little 500se, just a porky motor with expensive shafts.

If it were me, I'd run it on 10s with mod 1.0 to stay with the stock 6mm shaft, it will be fun with 600mm blades, but those grips shouldn't be pushed too much past 19-2000rpm, they don't have the bearings for long blades and high rpms.

500kv x 35v = 17500rpm ..../ 106t = 165.....2000rpm / 165 = 12t

the kontronik at 70-75% will be about .87-90 of 2000rpm, about 1750rpm

too slow....

nice thing about a big motor on a small rotor and the Kontronik governor is you can step up to 13t and drop the governing down and it will work out just fine.

I'd go 13t with 10s on the 4035-500....a 10s 3000 or 3300 would save some weight on the rotorhead so you can still slam her around

btw I have the 4035-400 on 10s in a 600 that weighs 8.5 lbs swinging 690s and it can party, you're gonna be around 7 lbs with the hotter -500

153 / (106 / 13) = 18.7.....hey you can use mod 0.7 too if you want to, the 17t and larger are 6mm

had good luck with mod 0.7 on 600mm rotors, the 500se is light, worth a try
