brushless 1/5 4wd conversion about to begin! couple questions.

Lookin' SHWEET !
Carbon top plate came out nice,good job.
Q; will you install a brace where the cut out is on the right side of the chassis ?

[KaztheMinotaur]

Would the 2215 2Y be too much on 12S?

You can wire brush that copper color off of the rar hub carriers if you don't like it. I did that to come of my copper stuff.

The stock shock shafts are very thin and bend easily. I am running the Baja front VVC heavy safts. They are a little long but you can take that extra lenght up with some tubing under the piston.

that was the main reason i bought that parts lot on ebay. it has a set of shocks with the 6mm phatdad shafts already on them. i will just end up using those. i did also already buy a set of front VVC shocks though that i was gonna use but then found that i couldnt really mount them up. if you switch the shaft do you need to switch the parts at the bottom of the shock case that provide the seal around the shaft?

a brace? i dont like how the side parts of this chassis have all the cutouts. that will just let dirt in. so i already have a fix for this. i found some huge mudguards from another 1/5 kit that match up sweet. i will be mounting those up soon. i want to keep the inside of this thing as clean and dry as i can being as it will have $1k worth of motor and esc in it. lol.

[KaztheMinotaur]

Yep, you need the VVC bottom caps also.

hey kaz,
do you know if the baja 5t body fits well on the rampage? i love the 5t body and it looks a lot more like a truggy body but i dont want to drop $180 if it doesnt fit very well. mainly i want the sides of the body to extend at least down to the chassis. i have my body posts lowered all the way and the rampage MT shell comes down all the way. just wondering if you have tried the 5t body?

btw, the 2215 can handle 12s i believe but that pretty much maxes out the rpm capability if i recall. anyway, i will be running 10s and just use gearing to get the desired speed. i used the rc calc just the other day and it estimated this thing at around 60mph with what i put in. that will be insane. i am thinking its gonna be in the 50mph range. which is fine by me. my buggy does 55mph and it is so insane already. i cant imagine this huge beast doing more than that.

If you're still considering 1/4 scale servos, here's one from Hitec for $40, puts out 343oz in .14sec at 6v.

[KaztheMinotaur]

Don't know about the 5B body. I know some FG bodies fit on though.

If I were buying new servos I would get ones from the new HV line from JR or HiTec.

That 805 is nice servo. We use them in gas boats all the time. The only downfall is the Nylon gears...

There's never too much power...

dude, i love your avatar!

so i have been looking at servos non stop the last day or two and having a tuff time deciding. i have looked at that hitec one but i wont get a servo with nylon gears no matter what they say it is rated at. just a thing. i got to have metal gears. so here is what i have found. i already bought one servo that i thought was a 1/4 servo but it turns out its regular size. just got it yesterday. its the futaba s9157 rated at 425oz so i will just keep it for the brakes.

i think i want to stick with either futaba or the hpi servo though cuz that way i can use the HD HPI servo arm.

one option is to get the HPI sfl 10 and then get the metal gear upgrade here.

http://www.davesmotors.com/s.nl/c.88...t.A/id.5654/.f

there is still one plastic gear this route but its good for over 300oz at peak torque.

then there is the new sfl 30 which is good for 250oz thru the entire sweep of the servo arm. http://largescalerc.com/index.asp?Pa...l=&strCompare=

then there is this homemade servo on ebay that is all metal gears and 310oz
http://cgi.ebay.com/ws/eBayISAPI.dll...m=200342803691

but whats a "programmable servo" and is the spektrum dx3r a analog or digital radio? what is the difference between digital and analog servos?

and here are the futaba servos i am considering:

http://largescalerc.com/index.asp?Pa...l=&strCompare=

http://www.servocity.com/html/s5301_...hi-torque.html

http://www.servocity.com/html/s5302_..._hi-speed.html


here is what i dont get though. how come the standard size servos put out way more torque than the large scale ones? also, when it comes to the large scale servos the nylon gear ones offer mor torque than the metal gear servos. why is this?

why cant hitec just offer a 1/4 scale titanium gear 480oz servo like their new standard size servo? that would be sweet!

i am pretty sure i am gonna get the either the futaba s5050 or the s5301. i just need to know whether i need a digital or analog servo and what difference does it make.

so many questions.


oh, and check this out! wish this would have been on ebay 2 weeks ago.

Torrents - as in Bittorrent - a popular method of downloading software or media content through a peer to peer network. If you are willing to use an unlicensed and cracked version of the software then it is available for free. I'm not advocating, just making aware of options.

I use a fully licensed version at work, but at home to mess around with on various personal projects, I use the unlicensed version I downloaded. And yes it is a few thousand to purchase.

The 5T body has a longer wheelbase than the Rampage. The Proline 5b/5t "conversion" body might work though as it has a slightly shorter wheelbase.

I'd go with the S5301 if you're sticking with futaba. FYI the Hitec I purchased for my FG came with a heavy duty aluminum servo arm, not sure if they all do or not. As far as digital goes, it depends on your radio. Some radios can't use analog servos because of the module in them. Thats all I know, maybe someone else can shed more light on this subject.

As far as programming servos, unless its a track vehicle and your that picky or some highly specialized application (robotics come to mind) its not something most would mess with. Most high end radios have enough adjustments (epa, subtrim, etc) to not need the feature.

cool. thanks. i did find an article today that explained the difference between digital and analog. i am gonna get the s5050 after reading this article.

i wish i had a 5t body i could check to see how it fit. i love how that 5t body looks.

here is the article: http://www.futaba-rc.com/servos/digitalservos.pdf

DOh!
I just got done dismantling a perfectly good s5050, you should have been about a week earlier :(
