Possible brushless setup (your thoughts)
 
A made a thread a couple days ago on what would be a good buggy to convert. i have decided on the Hyper 7 tq black. Now, as far as the setup goes... i found a $60 radio that has $25 receivers sold seperate. I would run the stock servo, rcm motor mount. I'd like to run a MMM esc, and a 80mm medusa on 6s zippy from hobby city. Looking for your thoughts on the setup... things to improve on, etc. Also, just to make sure; can the hyper 7 DL handle the 6s? i know it will be crazy, but hopefully it will keep me entertained! :yipi: Looking for your imput... Want to make sure i get this right the first time.

On a side note - i made $15 on easter, and $50 today for helping my grandma. I have to ride over to my grandpas to pick up $40 for my work over there too! That's over $100 saved so far... Plus i am going to sell my phone, and maybe a rc. the stock kit is only $300 minus what the nitro crap sells for. On my way! :party:

6s gets my vote. There is no such thing as to much power.

e-rev project 04.14.2009 02:51 AM

as long as the $60 radio is 2.4 ghz.

azjc 04.14.2009 03:02 AM

6s would be good as long as it is mated with with the right motor, and you go with a pack that is smaller than a 5000mah...probubly 3700-4300 due to weight...lok to keep the battery weight below 650 grams

Always Dreamin 04.14.2009 10:14 AM

the $60 radio and $25 receivers are 2.4ghz.

As far as mated with the right motor.... how does the 80mm medusa sound? And that is a little less mah then I wanted, but i can always get another pack. you are talking about zippys right?

brushlessboy16 04.14.2009 10:19 AM

6s in a buggy is overkill. i run 4s in my truggy and can outpace nitro buggies.

Zippys are worth there weight, but if you have money to spend get an RCM pack or enerland based pack. and 80mm medusa is too big for a buggy. Try a 70 or 60. remember that the buggy will be about 8-9lbs when your done- Doesnt need THAT much to make it move how you want it. MMM and a 1512 or 2650 seems to be the hot ticket in Buggies

lincpimp 04.14.2009 10:46 AM

I agree that 4s is fine in a buggy. With 6s you run into problems fitting the larger lipos under the body, and the addl weight really throws off the balance. I run a 1600kv medusa 60mm in my hyper8, and plan to use fp 3200 5s lipos, as my 2170 6s setup just does not have enough runtime.

As far as equipment, a decent budget setup would be the hobbywing 80amp esc with a 2200kv 60mm medusa on some sort of 4s lipo, around 5000mah 20c+.

Better would be the cc mmm 2650 combo on 4s.

The budget setup could easily be done under 300 bucks for motor esc and lipo. You will spend 50-75 bucks more for the MMM setup.

azjc 04.14.2009 01:19 PM

if you go with a 6s setup choose a motor that will get you a max motor speed of 35k and this will give you a better run time than a 4s 2200/2260kv setup so you can afford to run a smaller pack. One advantage that the 6s setup has over the 4s is it will run cooler, if you live in a hot climate this will be an issue

Takedown 04.14.2009 01:33 PM

He lives in orange county and once in awhile vacates by lake havasu. I use to live near lake havasu and its hot as hell in the summer. As for orange county, it can get quite hot there id imagine aswell.

FastXR 04.14.2009 01:58 PM

I would go with 4s and a 60mm Medusa in a buggy, personally, a nice light weight setup that should work nicely for you.

Always Dreamin 04.14.2009 05:06 PM

:lol:Ryan and i talk outside of the forum

... I wouldn't mind the thought of 4s, just don't want to get bored a month later and have to invest in new electronics.

And yes, although i do go to Lake havasu, it is for no more then a week at a time. I have had problems with temps on some of my cars in the past. especially if i am going to build up a battery collection to hopefully get longer runtimes, i wouldn't like to worry about heat.

can anyone confirm that the 80mm WILL NOT fit? I like the thought of $300 for batteries and motor/esc. What about running a HW esc with a medusa motor? or a mmm and medusa? So many options. i guess it depends on the budget mainly. Keep temps in mine as those are fairly important to me. I have seen buggies on youtube on 4s, they look pretty fast. Then again, i don't just want to keep up, i want to be long gone. :yes:

I like the hw esc, but i have heard of failures, and i don't want to ship it back to china... i really like the MMM esc but it is also more money. And i am undecided on if i should use medusa or the cc motor.

Going to look into it more later.. at school now :whistle:

scarletboa 04.14.2009 05:37 PM

i say, go for a hw 80a esc, medusa 60mm 3100kv motor with a 4s lipo. that'll make the motor spin at about 45k rpm and will leave any nitro in the dust.

Takedown 04.14.2009 06:00 PM

Im not a creeper. I just pay attention and have a good memory. :lol:

BrianG 04.14.2009 06:04 PM

...and nothing better to do apparently. :wink:

Takedown 04.14.2009 06:09 PM

Most likely...

Always Dreamin 04.14.2009 06:13 PM

just had a major brain fart! the triton 2 has a 5s limit... so that leaves me to just pick out a 4s setup.

Takedown 04.14.2009 06:17 PM

May I ask why you excluded a 5s setup?

Isn't 45k rpm too much on a BL motor?

I also think 5S would be nice for you... Mike has some nice 5S 4500 packs that should give you good run times at 538g so it's pretty decent weight wise (well under 600g) and run times should be well over 15min more like 20ish. A 1900kv motor would give you right about 35k rpm, which is from what I understand the rpm you are looking for in a buggy running BL.

Another setup that is REALLY tempting me would be running 6S with mike's 2600 packs, they only weight 380g and will last a good 10 min racing, with a 1500kv motor this could be a really killer and cool running setup.

Man, sooo many options :)

brushlessboy16 04.14.2009 08:29 PM

or you could always run a dual 3s setup...

45k does sound high, try to get your setup to rev between 35-40k.

Takedown 04.14.2009 09:47 PM

Betcha he brings up how charging will take to long ben. ;) But ya thats what i'd do if i had a 5s limited charger.

Always Dreamin 04.14.2009 10:49 PM

what about charge times? :lol: but yeah... 2 hour charge times are not exactly what i want. And Ryan, I don't know why i excluded 5s. I guess i either wanted to have a nice 4s setup, or go all in with 6s. I don't do middle stuff too much. :whistle:

i can charge them at night, but then once they are gone... 2 hours later and I am finally running again. I figure if i go 4s, i'd get good runtimes, along with a cheap setup. (hw 80a esc) And FYI my biggest concerns with a BL conversion is cost, and runtimes. and 2 hour charge times will only make me frusterated.

Takedown 04.14.2009 11:57 PM

Who called it! If you get two 3s 5000mah lipos and wire them in parallel and hook it up to the charger just run it as a 3s 7000mah pack. It will charge it at 1c only so thats the only way possible to be able to charge as close to 1c as possible. It should be fine seeing how the t2 has an overvoltage protection.

Takedown 04.15.2009 12:01 AM

Oh and your going to need a 7a or higher ps. I would just sell the t2 and the ps and buy a 6s charger from UH. That way you can charge in around an hours time.

Always Dreamin 04.15.2009 12:02 AM

New charger was not in the budget... i'd rather go 5s at that point

that reminds me...

Takedown 04.15.2009 12:07 AM

You could buy a brand new 6s ac charger and a 10a powersupply for the amount that you could the t2 and ps... UH is dirt cheap.

Always Dreamin 04.15.2009 12:22 AM

A $300 setup, a $200 roller, a $45 motor mount, the LAST thing i would think about is a new charger. not that i don't want one, but 5s should be plenty fast.

Takedown 04.15.2009 12:38 AM

Exactly.

Always Dreamin 04.15.2009 12:42 AM

But that does mean a more expensive esc. the hw80esc was dirt cheap. Now i might be better off running the mmm? but with what motor

Takedown 04.15.2009 01:01 AM

MMM or a hw150.

Always Dreamin 04.15.2009 01:08 PM

I would like to set a price for the two setups...

Setup 1:

HW80 esc
Medusa __mm motor???
Zippy 4s
RCM mount

Setup 2:

Hw150/mmm esc
Medusa __mm motor????
Zippy 5s (probably lower mah then the 4s would be)
RCM mount

Which setup would run cooler? with the 4s i would get more runtime, but the 5s i will get more power. if I can get a nice 4s setup for considerably cheaper, i will have no problem with the power. But if it's not much more, then why not? Don't know how many mm/kv motor to run on the setups. With 5s i will probably run the MMM, but the Hw150 is still up for grabs.

If you gear for the same speed you will have the same total draw. Personally I would stick to the 4s setup with the cheaper esc. It is just a buggy, not much tire/wheel weight there. Plus you do not really want a big heavy lipo in there, will just upset the balance and cause more draw and heat from the weight.

Plus 4s will be cheaper than 5s, both esc and lipo. I would get a medusa 60mm 2200 motor and a 4s 5000 25c lipo. A decent power supply and charger are a good investment for electric, maybe put some money towards that first.

4s sounds good to me! I already have the Novak black box power supply and triton 2 charger, so I am good there. You sure 2200 kv is high enough? I was looking at the CC neu motor that was 2650.

brushlessboy16 04.15.2009 04:25 PM

2200 is alot for a buggy too... my friend runs the 2650 in a hyper7 pbs.. its plenty.

Always Dreamin 04.15.2009 04:51 PM

The school computers have youtube blocked out, but I know that the 2650 hauls. I am just wondering if the 2200kv will also be fast? Temps are important, so i guess that would work.

I think i have mysetup.

Hw80 amp esc
Zippy 25C 5000mah lipo
Medusa 60mm 2200kv motor
RCM mount
RCM battery tray

Always Dreamin 04.15.2009 04:55 PM

There is always the 2300kv 70mm medusa. Only $10 more, but is it worth it?

If it is only 10 bucks i would go with that. The longer motor will handle the load better, and temps will be better too.

Always Dreamin 04.15.2009 05:04 PM

Alright. What about just going balls out with the 80mm? it's not THAT much more, and if it runs cold. temps are important.

and anyone know how the hw80 will run???
