1/5 Brushless 4wd Conversion

[Chadworkz]

That one is cool and all, but I would rather have the first one you posted, with the nylon parts and the clear body...it's more bashable, the one above is just a "looker" and would get bent up under severe 1/5 bashing.

i agree. its just nice to know that aluminum upgrades will be available. i prefer to have aluminum hubs, hingepin carriers, and things like that but keep a-arms and other parts plastic for some flexibility.

seriousloy that outrunner and the cells you will need - did the spread sheet power to weight ratios etc - it adds 33% mass to the stock car and its power levels start to look pretty lame and it is VERY innefficient at the amps te car will run at most of the time - but then at 2.3kg its a hell of a heat sink.

If you can change direction smaller motorswill do the job better and not require the sort of strengthening the proposed motor will require. It will be quicker and more nimble .

After reading a bit more, I am probably going to use the layout Ryu James used on his Rampage conversion. Outrunners look cool but the inefficiency, heat and the fact they dont like to be dirty makes them a hindrance IMO. Now I need to find a suitable motor/esc/battery combo that wont break the bank. Looks like more research for me :D

its a tough decisions cuz all of the "cheaper" options out there have not had good feedback. for example, kershaw designs makes a 1/5 brushless motor for a couple hundred bucks but i have not been seeing good things about it online.

maybe you should just get a Neu 2215 from offshoreelectrics.com for $425 and then a Castle HV 110. that would put you just over the $600 mark and then you can have my CNC'd motor mount and spur gear for cheap. i will pm you price. it would be a sick buggy but you almost need to wait to get it before dropping coin or doing too much.

obeast,

just a couple of quotes to consider from the forums as i have been reading more on 1/5 conversions:

"Neu, Plett, Lehner and Castle are the only guys with viable 1/5 inrunners I know about"

"I did a lot of testing with the 1717 motor and found that the top speeds are right about the same as with the stock gas motor, but the acceleration is much better."

that quote is with a baja conversion which weighs 28lb. it might do well on a 20lb conversion and could certainly reach that 40mph mark. but, if the buggy weighs 20lb now its likely to weigh a couple pounds more after redcat does their improvements to it.

The lighter setup will serve you much better. A great motor with a 12 cell single series pack will only weigh 2.1 kg and give much more power and much better power to weight and 12-20 minute runtime depending on gearing.

The Neu 1917 variant I sell has 8mm shaft and fan and runs approx 18500 on 10 cells (5.2hp peak) or 23000 on 12 (8.5hp peak) - they weigh approx 1.1lbs. They run cool with bucket loads of power and cost $249. I recommend a sock or a open cell foam filter for motor cooling.

You can use cheap esc like the turnigy 200 and moderate rate cells - at least 30C cont and have a fast relaible car.

I just exchanged a couple emails with "Mike" at RedCatRacing and he says they are 6 months out yet and a roller is a slim possibility.

Last I heard the new gas versions would be out in September. This brushless version may not even make it to the states, due to cost.

The attitude I got from the RedCat Rep I'd say they'll be here for sure. I'm willing to bet the demand would be high enough, I'd surely buy one!?
A giant "1/8th scale type" 1/5 Buggy would totally Rock !

[Obeast44]

I sure hope so! Theres a lot of interest in it over on www.redcatrampageforum.com. I really do hope they bring in the electric version, the main cost reason I mentioned is that it uses 2- batteries. Given Redcats trend of supplying the lipos and chargers for most of the brushless stuff, it might be a little pricey. Hopefully, they just decide to drop the lipos and chargers. Considering most of us interested in it, already have those.

I don't see why everyone is limited to the discretion of Redcat Racing. Wonder who they buy the product from and if someone else wouldn't just import the same model under a different brand name.

[Obeast44]

Well for one reason, spare parts. If they dont carry it, itll make it hard to get parts.

[killajb]

Same point source I'd like to believe for spares. Like the king motors baja, what would stop the OEM from selling to a different distributor?

[Obeast44]

You cant go directly to HSP and buy just one buggy, then order a part here and there from them. They wont even respond to a request for just one. They have distributors for a reason.
I dont know of any HSP distributors in the US other than Redcat. And theres no way im paying/waiting for parts shipped from overseas :D
