my hands are roughly 9 inches...


but seriously i could fit the 2230 if i just flip the front and rear drive shafts and make new holes for the center diff assembly to mount. hmmm. keep the ideas coming guys.

On the spur gear front, are there not any other 1/5 scale trucks/buggies etc with a 'normal' center diff unit you could retro fit? Seems like a lot of hassle to get a custom gear made, especially if you might need 2 or 3 to adjust the gear ratio..

Liking the giant motors though, you just know something that big is gonna be alot of fun.

thats what she said..... just not to you



Im sorry that was too easy..

Just borrow this setup from a muggy for steering:



Dual 7955's won't have any issue

But then there is issue of the servos fighting each other.

[brushlessboy16]

that is what the linkage in the middle does, you adjust that so they dont fight each other....

i already picked up one of the JR high voltage servos and a Castle BEC so i can run at 7.4 volts which will let the servo pump 480oz of torque. about the best available from what i can find. i picked up these aluminum servo mounts on ebay that i plan to mount for both steering and brake. hopefully they are strong enough. i think they will work fine.





as far as finding a "normal" center diff from one of the other 1/5 kits it aint happening. not by me anyway. i have looked everywhere. all the 4wd units use a conical style gear in the center. i have already posted some of my gear ideas from the other kits earlier in the thread. perhaps someone can tell me the diamater of the spur gear on the rear diff of the baja 5b. i would like to use that as a center diff and just have a custom mount made but i have no idea what size it is. i think it is too big though. can anyone tell me?

here is what i have decided to do. i ordered this spur gear in 37t. (a 43t is also avail.) it looks to be the easiest one to modify. all i will have to do is bore out the middle to 12mm and drill 4 holes to screw it down. i think it will work. if it does work i will can order the 43t and do the same to adjust gearing if needed. but i want a fast ride so i am starting with the 37t and see what happens.

Very nice. I have the Rampge MT with a ported 30.5 CC engine. I hope you are able to drill holes in that gear to make it fit.

[lincpimp]

Do you plan to use mod1.5 gearing for the pinion and spur? Or mod 1? What is the diameter of the bevel center gear?

[lincpimp]

Ok, had a look for a 12mm bore, hubless, mod1.5 steel gear. Came up with this:

https://sdp-si.com/eStore/PartDetail...70&GroupID=591

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.

[KaztheMinotaur]

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

[nitrostarter]

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]

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