Why do you add a connector good for 3-5A tops on a 12-15 ESC, especially when it is clear it's spliced on? It will simply have to be discarded before this thing can be properly used.....

[tallflyer]

I did Test using different types of conectors! and after about 50 hours of flying my slowstick with this setup I have not had a failure!

The motor only pulls 3-4 amps using this setup using the prop that I supply!

I also did a study on the most common battery packs sold for this type of plane (even gws using there stock 350C motor (d) gear and there new lipo battery pack have a male bec installed.

I have sold a good qty of this setup and have not had one come back with problems!

(I market the flightpack as a truely plug and play setup) and test each one of them by hand before I ship with a 2-cell 7.4 and a 3 cell 11.1 and wont send them if I dont get the results I'm looking for.)

If you want to buy them and connect your own conectors and use them for another setup well then maybe this is not the setup for you!

(A question for you if i might ask. I tested thundepower lipos- xpower lipos-gws lipos- dualsky lipos some off brand with no names and all the ones I tested came with pre installed male JST plugs! should these then all be removed and replaced with another conector)

[BEC]

Well, if it only pulls four amps that's fine. The connectors can handle that at least until the pins start to get loose from connect/disconnect cycles.

Those little JST connectors, like their Tamiya forbears on larger models have one virtue and one virtue only - they're cheap.

I'm glad they are working for you.

[tallflyer]

Bec!

Do you think I should sale the kit with no battery connector installed and let people do it themself! put on there conector of choice!

Im open for input from anyone!

Why do so many mfr's put JST connectors on there packs?

[BEC]

Well, because there are so many choices available, some good, some less so, no matter what you pick many people will have to remove them anyway.

As for why som many battery pack builders use JSTs.....my only guess is that back when GWS IPS drives were new tech (and only drew a couple of amps anyway) some ESC makers started using the JSTs because they were cheap and worked, and now so many of them are out there that battery makers have just installed the JSTs to be compatible. This is one of those situations where just because lots of people do it doesn't make it a good idea (in my opinion anyway).

But over 3 or 4A they're really overloaded and will eventually fail.......

Jeti's new Spin controllers come with connectors for the motor side (and they supply both halves) but they're not installed - they know that while many will want the connectors many others will not. BTW, they do not supply any battery connectors at all - even on the smallest ones.

At least Great Planes uses the mini-Deans (a MUCH better plug) on their small brushed and brushless controllers. Most ESC suppliers don't supply a battery-side connector even if they do the motor side as you have done with the bullets (a MUCH better choice).

Thanks for all the great information!

I'm trying to market a package towards the new pilot that just want to plug his stuff in and go fly!


He or she might all ready have a GWS slowstick type plane and just wants to try brushless to see what all the talk is about!

The basic builder does not want to have to buy a soldering iron/solder heat shrink tubing, connectors! anyways I think you understand my point with that!

They just want to fly!

The problem is that there is no standard in the industry!

[BEC]

The problem is that there is no standard in the industry!

That's it exactly.... and the JST is close to a standard - but it's a bad standard, just as the Tamiya plugs are on bigger batteries in the car market and in airplanes, say, 10 years ago a bad standard.

I understand wanting a plug and play setup for those who would rather not mess with a soldering iron or crimping tool. I don't have a good answer but the mini Deans is a better choice for up to 10-12 A, even a bit more. Unfortunately not many sell batteries with them - even distributors who do sell ESCs with them (like Great Planes).

As a relatively new flyer (february 2006) with a lot of new planes and parts, I have learned two things. Anything but a Deans is a waste of time, and any plane that comes with a brushed motor is a waste of money.

I guess the Deans thing is a matter of taste. But if you want consistent connectability, you need to go with something like that. All my batteries that came otherwise configured, had to be updated. Same on the ESC end, obviously.

I mention the brushed motor thing because they are a waste in my mind. They don't last long, don't fly as well as brushless, and are way too heavy. So you end up going brushless and having a bunch of parts you paid for but will never use in another application. I have a box of motors and ESC's I won't use.

I like your plug and play idea, but I responded here because I too had the same knee-jerk reaction as the other poster. I guess I equate a JST connnector to a brushed motor--simply a waste of time and money.

First off Brushed motors are not a waste of time its what got many of us old gas flyers into electric planes, when the gws eps100 then 300 now 350C motor came out we all stood up and said wow you can do that with a electric motor! and the motors were $16.00 still a great bargin in my book! and the esc (electronic speed control) well they were about $19.00 at the time so for $36.00 you had a good combo.

Check out the video all stock planes using brushed setups!
http://media.putfile.com/GWS-Planes

All planes in the video were flown with Stock Brushed motors!

Most of these planes used heavy (ni-cd) battery packs remember those battery packs that had memory) jst connector..

Then came (Ni-mh) no memory packs held charge longer. (jst connector again)

Next thing that started changing the game was lipo packs! they came out and the packs were lighter and gave you doubled the flight times we all got excited again! (oh my god Jst connector again)

(then everyone Bi--hed) that some of the new high cap packs did not fit into there old models ore they were 2 small or two big and the plane kits had to be modified. (could talk all day about that!.

And the first gen lipo were about triple the price of a standard 6-7-8 cell ni-cd ni-mh pack! a stock 6-7 cell was about $19.00 and a lipo was about $45.00 back in the day!

and somewhere between the ni-mh stage and the new lipo we started hearing about micro deans connectors and new types of high amp wire leads.
that were needed to get the most out of your gear! Most kits were still being sold with Brushed motors and only required a GWS ICS300 type speed control
to work good (jst connector)

The Internet has passed information on about better this and better that and people have tested this and tested that and people say this is a waste of time and that product Su-ks, well most mfrs build for the masses and then let us as builders upgrade to what we think gives up the best performance that we are looking for (read that line again THAT WE ARE LOOKING FOR)

Ok now we can talk about brushless motors and esc's (well maybe not as much as you think) they are dollar for dollar the best motors out there and offer more power and performance then any brushed setup! (they are sold as upgrades still at this point) and dont come with most stock kits as a way to bring the price down and get more people involved in the hobby.

(After doing some research and building and flying a bunch of planes) not just going off what others said! I decided to start offering the bp12 combo as a upgrade to people that have a GWS slowstick type plane and were looking for an upgrade in performance and could still use all there original gear! (ni-cd or ni-mh or basic lipo packs all with JST connectors) no work would be needed just plug it in and go flying.

As like everything people are giving the right to offer there opinion! good bad or otherwise. (don't just say that stuff is a waste of time) offer information that helps new pilots young and old and of all income levels! information that will help them see all there options, not just your side of the story as you see it)

I have been posting on the boards for along time, I have taken pictures and posted video clips and have have tested and flown more planes in the last 10 years then I could count!

And Im allways open to new stuff (kinda like a kid in a candy store)

So the bottom line is this after all that was said! use what you like and can afford. go out and fly and have fun. try when you post remember to take out emotion.
(I had a guy post on another thread that he thought this mfrs plane was the worst) it didnt fly at all! was as he called it a real piece of(S--T) anyways I run into the guy at a flying club later that year and funny he had a car full of broken parts and after watching him fly it was not the kits!

Just get out and have fun, go flying..

Well, I read most of what you wrote and scanned the rest. I have to stick to my opinion. And you should take it for exactly what it is worth - a single opinion. But I am a customer in the market, so it is my opinion that counts, at least versus yours (this is not to say that you may not have found a robust market for your package). I also listed my experience in the hobby so you could get a sense of why I might have this opinion.

Brushed motors and ESC's ARE a waste of money. I'm not going to re-outline why. I think you shed some light on why they exist. My sense is that they were a stepping stone. But they are now obsolete (maybe not quite yet, but rapidly approaching that!).

I think I got involved after brushless/lipo "killed" earlier technology. So I am not clinging to an older, possibly then-cheaper, technology. I was getting a taste of it early on and trying to understand why anyone would not want to start with brushless from the get-go.

I guess I feel strongly about this due to my experiences with my PZ planes (Cub and then the P51). I loved those planes at the time and they were a great "stepping stone" for me as well, coming up the curve. But when I look back at how much time and money went into trying to keep them powered, it's difficult not to feel an aversion to the technology. I can't see how it would cost more money to swap a prop shaft in a brushless motor versus a brushed PZ one.

My intention was not to start a battle here. You ultimately will decide what your customers are going to pay for. I simply read what you posted and felt compelled to give my opinion. And for this particular potential customer, I am sticking to my guns.

I just looked at the join dates and number of posts. No contest as to the member with most experience which in my book is knowlege.

Let's not drift too far away from the original topic here......there are endless discussions about the merits of various motors (and connectors, for that matter) up in the Batteries and Chargers and Power Systems forums.

I've not experience with this particular motor and that make of ESCs so I'll have to be quiet about that. It so happens I do now have a plane that uses a Slow Stick fuselage - the Stevens Aero stik. Hmmmmmmm........
