Sh#t storm of GST's here's mine so far
 

i'm starting to see alot of these conversions which is really nice. there just aren't enough. i got this roller a few months back and was on a very tight budget since introducing dave ramsey into my life for the build. i already had most of the things on the truck. the only thing i've purchased for this build was the motor with i requested as a bday present from my mom since castle was having their sale, and i bought the 66t spur gear.

the motor mount was very difficult for me. all i have for tools are a dremel and a cordless drill and some bits. i plan on redoing the mount in the future, but i was anxious the get the truck in a running state to play since it was my only rtr at the time.

specs are a castle 1717 motor, mgm22418 esc, and a monster robot servo jr dsr8801. as of right now, i only have a 4500 30c 11.1v battery to run in it. i wont complete my motor mount or battery tray until i get the batteries i will use in the truck at six cells. enjoy

One servo i s enough for you? I prefer two servos in push-pull setup.
I hope to see soon the end of your project.

its way plenty. the weak point right now is the spring, but i haven't even looked to see if its adjustible yet. servo is rated at 396oz and .14s at 7.2v. i'm not sure what i'm getting now, but it moves just fine.

That center diff is interesting, 2 spurs?

Yes, is the original diff inside the original nitro gearbox with reverse

unfortantly, the allen screws are stripped so i can't get it apart. i've been watching for a center diff for a matrix tr arena, but got tired of waiting and just ordered the spur. i will fix the problem later, but for now its just a little more weight to spin.

well, i got a chance to get a small feel of 25volts in this truck. its going to be insane. it was dark once i got the batteries charged, but i chanced some throtle stabs in the front lawn. first one resulted in what looked like two flips. that was full throtle and scared the crap out of me. i went again about 1/2 maybe a little more and still easily completes flips. i can tell now i may be taming this thing some how. i'm hoping to get some daylight running tomorrow so i can really feel it out but we have rain in the forcast so i may be screwed.

i'm also thinking a center diff will be in order as first attempt to control it a little better. mine now is locked.

Somebody needs a wheelie bar! :lol:

i have plans on making one using a roller blade wheel. already started mocking it up.

Are you using the 16 Pinion in the photo?

got a new mount made for the motor and diff and i found out very quickly that a locked diff with a 1717 on 6s is a bad idea. did a high speed flip(insane power) and landed on front tires with throtle and lost a tooth on my front pinion. so far i've gotten less than a min of drive time with my newly purchased MMM in there. i fried the mgm22418 right after i put together my mount.

still a work in progress. i'm going to score a complete diff on ebay and get rid of the locked crap. if i'm still breaking stuff i'll look into a sliperential.

How does these trucks handle?

He has no idea. lol

Sorry about your misfortunes. I like the fact that for the first time ever Castle green matches.

I was asking how any of them handle, not really just this one.

you can also play with the esc to tame that monster, thats the kind of power i like may not want to put in on the street but off road where there is some give

its easily my most powerful truck i've built. this was off road that i did this. thru grass. the truck was running before i did this and on 4s with a different esc. it handles ok, much better for fast driving with standard maxx sized tires. the stock ones change things alot but looks cooler. to compair it to a lst, its stiffer i guess. not as plush, but seems to turn better at high speeds.

My GST with 6s 11 pinion and 66 spur is perfect. Yesterday i downgraded my MMM to 1.21 firmware and cogging issue has disappeared.
I use GST original tires.
I have no idea how Tashpop can use it with 4s.

I have an E-LST XXL and it handles much much better. LST has a lower setup, it's lighter and the wheels are smaller.

i have much better setup in this than my lst, could be a spring issue and also the steering servo. i just set that truck up for a basher for my daughter. the 4s setup i had in the truck was just temporary until i got my other 3s to make 6s that i'm running now. it was 5100 25c pack and i had that taller pinion gear from earlier in the truck. easily made the truck fast enough and fun for bashing without being overpowered. now i'm setup with a 13t pinion. i don't know at this point how the mmm is setup. i got it used and only programed it to the radio and went on a test drive before it broke.

want the gst to handle like a racer give it a stance like this.

this was during mock up phase, but you can see what these wheels and tires do to the truck.

still waiting on parts, but while i am waiting to fix the diff i got in a fs gt3b rx combo. i was running a mx3 but couldn't pass up the deal. its pretty neat looking but feels cheap, but not too bad. the rx is real small, so i'm happy about that. if they are glitch free i will order the gt3 set since i need two tx's and i'll chose my favorit and pass the other to my daughter. im just a basher so these radios will prob. do just fine for the time being.

okay, i got the truck all back together with a non locked diff in the center. this has helped soooooo much. i can reach full trigger now. with a 13t pinion 6s is wonderful for power hungry moments. i can still do flips from standing still and upto maybe 15mph, then after that it won't but i can pull the front up any speed.

4s is alot more tame, and not too fast but the truck is very fun on 4s and handles great. perfect for lawn bashing and if a friend wants to give the truck a drive.

i haven't connected the new radio up, may get that done today and snap some updated pics of the truck.

Can we expect a video and finished pics?

i'm so lazy about getting videos lol. i can do though. it will have to wait, wife won't do it and my daughter is at my moms. i can get the updated pics soon though. i guess i need to try to get a vid before i break it again. i may try to shoot one while i drive.

here you go coolhand, best i can do by myself. i'm not going to try to hold the camera and drive this guy. these are just some flips with the center diff just recorded.

Damn Man! That was thrown around quite well!! :yes:

Nice Truck! What weight oil is in the CD now?

i'm not sure. i don't have anything as thick as whats in there. i used the diff from the front diff because it had some thick oil in it and put my new diff with thinner oil in the front. it feels like syrup, and very thick. i will get more vids with a fresh charge once i get a camera person. i still need to take some pictures too.

How's the Cen slider holding up? How do you have it attached to the center spur?

I have some Cen drive parts I was going to use on my Sav, but I was unsure of the long term durability of the sliders. Saves me from having to get a custom driveshaft (at least for a while.)

Thanks

Cool!
Video shows the power of it.
Thank you!

i lost a tooth off the front pinion but my slider still looks great.

sorry, no pics yet but my daughter was helping me film some video. its short because she kept missing shots. i was paying more attention to her making sure she was pointing the camera than the truck so my driving and landing sucked. the last bigger jump i broke the truck. i didn't think i needed the motor plate in the rear and i landing on the rear bumper. that bent both vertical plates and broke the cross brace.
