Mini Titan 4s motor choice

[Gscott]

What motor is recommended for 4s on a MT? I was looking at the JGF 450TH and 500TH since they are not overly expensive. My plan is to run the Evo Lite 2100 packs since they are the same weight as the normal Evo 1800's. Anyone running either of these motors? Which would give longer flight times? Also, where can I find the 10t 3.17mm pinion? The smallest Revco that Ready Heli had was 11t.

I don't think I have seen a 10 tooth 3.17 pinion. I think the shaft might be too big for 10 teeth. I am pretty sure you can get the JGF 450TH motor with a smaller 2.3mm shaft for the smaller pinions although I think most people run this with 11 tooth on 4s... I am not sure about the 500. There are 1 or 2 people in the Trex forum running the 500 on 4s on 11 tooth too.

No one makes a 3.17mm 10 tooth pinion. You can run a 11 tooth with a 3.17mm shaft and it will work fine on a 4s. Be sure you run a metal head!!

I run a 4s setup and this is what I recomend for a motor. A NEU 1107/2Y sorry but I can't recommend the cheaper motors. You get what you pay for and if you want reliable serious power a Neu or Medusa is the only way to fly. The Medusa is around $80 and has a 2 year warenty. It makes more power than the NEU but draws a tad bit more amps.

If you want to run a cheaper motor like the JGF450 or 500 then I feel your better off sticking with a 3s system. The reason being those motors aren't going to give you near the punch of NEU or Medusa on 4s! So if your wanting 4s power then you really need a 4s motor.

Himax 2815-3000KV is quite good matching to 4S for Mini-Titan . The motor is cheap and can output more power than 450GT . Running a 11T pinion is powerful enough for hard 3D flight and current draw is around 280-300mAh / min.

I have the jgf450th & I really like it. It is very cheap, very light, efficient, and has decent power.

I am running a 10t. they do make 3.2mm 10t pinions(smallest size physically possible). They are a bit hard to find but I believe I bought mine from helihobby.
http://www.amainhobbies.com/product_info.php/cPath/2_389_414/products_id/11460 I just found this... It looks like TT has some. I think the OBL motors are 3.2 also right?

On the 10t I get 2800rpms with enough room for my governer and get about 10 minutes of flight time doing mainly sport flying and some loops, rolls, & flips.

If you fly harder you may want a higher watt motor but if your after flight time I think the 450th is a great choice for the price. A NEU motor would be better but is 2x the price and is heavier.

I tried the stock motor (resting now with the original ESC in a drawer).
- The Z-Power Z-450 TH on 3S
- The Z-Power Z-10A on 3S and 4S
- I prefer the NEU 1107H / 2Y but that's just me..

Happy Flying

Happy Flying What pinion are you using with that motor?

[noguy]

NEU is undoubtabley the best.... However some of us are cheap bastards...lol

[henrik04]

What pinion are you using with that motor?

12T from Mikado

The JGF 500th on 4S is ever bit as strong and better then the NEU 1107-2Y, and it is 40 grams lighter......:wink:

[Funky]

I flew Gary's Mini Titan with the JGF500 on 4s.... that heli rocks!!!! Definately a great combo.

[LITHIUMSTATIC]

Funky, Shawn.... I repect what your saying but I've never owned any of the cheaper motors that have held up. I haven't owned a JGF500 but from what I've heard in reports it makes lots of power, but I've owned a few of the other cheaper motors Z-Power etc and found that I was disapointed or the motor died completely after some good thrashings. Even if I got to spend more money or gain some grams of weight, at least I know it isn't going to turn into a paper weight overnight.

Just my .02;)

That is interesting. Is there any review of this JFG 500? Must be quite power hungry?
I don't mind the few grams.. More interested in efficiency (running cooler). And the 1107H / 2Y is not bad at all in this domain.

As I don't have one JGF 500TH I can't compare.

How did you came to the conclusion that this motor is better than the NEU?

[Funky]

No doubt the Neu is an excellent motor. I only had a chance to fly one Rex with a Neu 4S setup and it flew great.... tons of power and everything came down cool...

BUT... I had a very similar experience with Gary's Mini Titan. Its been a long time since I flew the 4s Neu so I can't make a direct comparison, but I have to say this 4s JGF500 rocked!!! A pro pilot flew Gary's Mini Titan for 5 mins of VERY hard 3d. The heli was running an 11 tooth pinion with a 100-90-100 throttle curve. I took temps immediately when he landed. 110 on the 2100 Evolite, 110 on the motor and 115 on the ESC. Those are VERY good numbers for the pounding that heli took for that flight. The Neu is possibly better, but with this kind of performance for the price, there isn't much reason to spend the extra money.

Durabillity is definately a concern, but I won't be able to determine this until I am running the setup myself and can rack up a bunch of flights. How many flights on yours Shawn?

[henrik04]

Even if guessing is mother of all goof, I assume you are talking about Fahrenheit degrees? If that's the case then it is 43.3 Celsius and I would agree that is a very good temperature.

However It would be nice to have a temp recording on board to check while in 'action'. I sort of recall that some data logger have temperature input as well.

Anyway thank you for the info.

Happy flying.

I did a long a$$ed review in the 450 rex forum on the 500th motor, graphs, amp draws, headspeeds, weights etc.... I know this to be fact. Sure the NEU does make fantastic power I am not denying that at all, as long as you do not mind a heavier heli is all. The difference flying the 500 JGF and the 1107 NEU on my little rex is very noticeable imho. The JGF being 40 grams lighter and having abit more grunt really shows.

[OICU812]

BTW the only thing negavite about the JGF I founds was like a Zpower the can can move up and down, so no big deal. Once I get one now I simply put in some 690 green loctite to the inner race of bottom bearing and it is good, nothing moves ever and since the motor stays cold that bond is not broken till you decide to heat it up to change a bearing if need be.

For the record I will be trying the JGF500TH, as well as teh newest 3300kv Zpower both on 4S with my Mini, "when I get it". I'll let you fellas know my thoughts, be well. :)

After reading this thread I have bought all the parts for a 4s set up but think I may have dropped a clanger! I have bought FP 4s 2170mah packs NOT 1800mah.
Does anyone know if I will have an issue fitting these under canopy and/or weight issue?

[LITHIUMSTATIC]

PV0841 is the part # for the new 4s battery tray. They just came out so it may be hard to find one. The EVOLite 4s 2100 is the hot ticket in flight time and weight. Still makes plenty of power.

Your 2170 should be fine and fit under the canopy. It's only .5mm thicker. My 1800 rubs slightly so you will most likely have the same problem until we can get our hands on the new battery tray.

FP 25C 4s 2170 - 222g
FP 25C 4s 1800 - 185g
FP EVOLite 18C 4s 2100 - 185g

[Chris Corbett]

Thanks for this, its really helpful. I will look out for the new battery tray!!!

[szo]

I just picked up a couple of 'JGF' 10t pinions from Miracle-mart. There really isn't a lot of metal on these, so you have to be very careful when installing them (lets just say I'm glad I got a spare)

[Prophet]

Hey guys one question, can you use the stock speed control if I use 4S and JGF 500th? Just need sepearate bec?

[ghtracey]

Should be fine, it doesn't draw more than 40A does it? Personally, if I was going 4S, I'd probably do it with a 450TH. That 500 just seems a bit hot to me LOL *** see edit

One thing to note is their specification on motor timing. They tell you to set mid or high timing, which requires a change to the stock ESC's default settings.

Edit - You may want to read this: http://helifreak.com/showpost.php?p=233024&postcount=18
Edit2 - I pulled my manual out. The Ace BLC-40 doesn't mention not being able to run the BEC circuit on 4S. I imagine though that doing so would probably cause more heat buildup unless it has a switching regulator.

[ghtracey]

Wow do the TT manuals ever suck. Ever read the section on motor timing?

There were 3 options in this funtion that allows you to maximize performance of your motor output. You could choose from low/med/high to fit with different brushless motors. Higher timing offers more power output at the expense of efficiency. Please check the current draw after changing the timing option in order to prevent overloading of the battery. The 3 options are listed as below:
- Auto Timing
- Soft Timing
- Standard Timing
- Hard tim ing


That's 4 choices for their 3 options. No explanation of what Auto does, and to top it all off, the JGF website (for the 450TH anyhow) says
Heli's should stick with soft timing but use Mid or High Timing. Looks to me like those options are mutually exclusive.

Maybe just leave the ESC at the default Auto Timing? LOL

[Chris Corbett]

Hi Guys

I just wondered sort of head speed you are running with 4s set up. I am about to finish mine and it would be useful to know when setting up etc

Cheers
