Here is the pdf info on the gear familar, just look at the 36t hubless info in the 1st table.

https://sdp-si.com/eStore/..%5Css%5CPDF%5C78501072.pdf

At 22 bucks plus shipping it is not too bad. Diameter is 57mm on the 36t gear, so not sure if it is too big to fit with the stock center bulkheads...

If those links do not work, search sdp si on google, and put this part number in their search feature: A 1C 1MYK15036

Linc, you are the f-ing man!!

that should be perfect. the stock bevel gear is 54mm. i could probably get a gear as large as 60mm and be fine. that 40t might even fit but i already ordered the 36t one. so now all i will have to do is have my machinist drill 4 holes and in 5 minutes i have my spur gear. woo hoo!! and Mike said his pinion gears should be available for sale by Monday. 11t to 22t pinions! sweet!
cant wait!

assuming this works the next aspect to be tackled is the mechanical brake setup. i have already orded some parts for this and have an idea of how to make it work so i will post some pics when the parts arrive. probably wont be til monday.

Are you going to mount the motor to the front? If so where are you going to relocate the radio gear to?

nitrostarter · 07.02.2009, 06:13 PM

Are you going to run that Mod1.5 gear of Mod1?

This thing will be nuts if you mount that 2230. I hope the diffs will take the power.

KaztheMinotaur · 07.02.2009, 06:49 PM

The diff gears were recently updated. They and the dog bone pins hold up OK as long as you don't land on power.

Ryu James · 07.02.2009, 07:00 PM

the only radio gear i have is a tiny spektrum reciever. i am gonna build a small waterproof box like i did with my slash and finding a spot for wont be hard as this chassis has tons of room.

i will be using mod1.5 gears. RCM is due to have the mod1.5 pinions anyday now i think and i have found a mod1.5 spur gear with the help of Linc the Pimp.

i dont think i am going to run the 2230 now. i do want tons of power but i defintiely dont want my driveline and gears busting everytime i get on it. i dont mind breaking my toys but i am starting to think the 2215 will be better suited. still not sure though. i am defintley keeping my 2215 no matter what. i will run it first and see how it does. if it feels underpowered or running too hot then i will worry about finding a way to get the 2230 in. but for now i am moving forward with full intention of running the 2215.

What ESC are you going to use? How many amps do you expect to pull?

lincpimp · 07.02.2009, 09:50 PM

Glad I could help! Nice to see someone tackling a big truck like this. I will be interested to see your success as I would like to do a truck like this.

thanks Man,

i really hope it turns out well. i am kind of a perfectionist and so i would like to think i will deliver a 1/5 brushless that will look factory. unfortunately for me (but fortunate for my wallet) the Redcat doesnt have near as many hopups available as the Baja.

Have you looked at 1/5's yet? you plan to do a 5b? or considering others?

i have looked at doing a 1/5 conversion for months now and i think the Redcat offers the best all around package for one.

$500 price tag
4wd
plenty of parts support and US made. HQ in AZ.
decent amount of hopups avail.
has its own forum
very large chassis/platform for easy conversion options
seems to be good build quality. its not like the FS or Smartech 1/5 stuff that is total junk.

by the time i finish my conversion i should have CAD files and stuff for a 22xx motor mount and different things and could perhaps do a couple of extra kits. not sure yet but i will be sure to post if its something i can make available.

i plan to use the Castle Hydra 240 HV, which is capable of 240amps. i will run to 5s, 18.5v, 5000mah, 30c packs in series. i may pick up some of the many differnt new 35c packs popping up everywhere now.

btw, do you have a rampage?

KaztheMinotaur · 07:06 AM

Yeah, but you inspired me to convert. Mine is still a gasser though. I love the power but I usually take it down to the state park to run it because of the noise.

That will give you close to 30,000 RPMs which is almost double what the 2 stroke gasser will make.

I think I might sell my helicopter that I've not done anything with in a while for funds.

lincpimp and others : Do you think the HV 180 would handle this OK?

Unsullied_Spy · 07.03.2009, 08:21 AM

Your conversion is coming along nicely! IMO it's smart to start off with the 2215, I am sure it has plenty of power for this application.

Thanks for the pics of the 2230, I've only seen a few pics of them. I can't imagine what a person could possibly use one of those for...

lincpimp · 07.03.2009, 10:06 AM

If you run 10-12s and are not trying to gear too high I am sure the hv180 will work. Up at 10 and 12s pulling more than 100amps is making some serious power. I used a 60amp esc on 8s in a savage and had no issues, so triple that rating with higher voltage in a 15th scale should not pose a problem.

RJ, can you weight the chassis without the motor or batteries as it sits with the tires on? Just wondering what it will weigh with my proposed setup, and I know the weights of all of the individual components.

aqwut · 07.03.2009, 12:50 PM

I think I emailed castle last year about using the Hydra's in a Land vehicle.. they said it wasn't a good Idea, if I can remember...

BL_RV0 · 07.03.2009, 12:52 PM

It's been done though.

Ryu- Maybe you can do a watercooling setup for the hydra? I mean... you do have all that extra chassis space...

MetalMan · 07.03.2009, 12:53 PM

Just to throw it out there: my XLB (1/7 4wd 15lb center diff buggy) now runs a 1521 2Y on 10s 3700mah Lipo through a HV-110. It's geared for mid to low 40s but it pushes out over 5hp on peaks (loads of power). The HV-110 heats up to about 120-130deg. after maybe 10mins. I'm sure things would cool down a bit if I played with the ESC settings but this might give you an idea of what to expect from an ESC.
