I would flip the motor to front right and run saddle packs - you have the room...

thats a good idea. i might try to do that. that would put more weight forward for better steering response and i have been a bit concerned about having all the weight so far back.

so i think this is going to be ideal. here are some pics of the layout this way. this layout will require i use the 2215 since the 2230 is too long to fit.

here are a couple of pics of the 2230 that just came today. thing is a beast. it would be fun to try this motor just to see what would happen. not sure if i will be able to though.

i have a couple of questions about servos. i have been looking for a 1/4 scale high torque servo. the highest rating i have found is like 300oz which seems low for a truck this size. i have the standard size JR9100 HVT servo which is capable of 480oz. so it seems this would be the better choice or will it not work as well since it is a smaller servo? is it ok to use a standard servo as long as it has enough torque?

HO-LY CRAP that is a beast of a motor! If you really wanted to you could move the packs further outwards and slide the center drive unit to the rear and allow you to run the 2230..... as for the servo- i dont think the size of the case matters as long as it has the torque to turn the wheels how you want them... Good luck- cant wait for the rest

HAND PORN ALERT!..... :lol:

Tell me you have small hands tho..... Wow thats a big motor!

my hands are roughly 9 inches...:wink:


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.. :neutral:

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 :lol:



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.

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.

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?

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

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
