Just received delivery of a 2024 AMP Pro. Thought I'd start a thread with my impressions as I use it and learn more. There doesn't seem to be a whole lot of real-world usage information out there on this model. Hope this will help others as they research.
Intended Use Cases
Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property. The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion. Wasn't an original use case, but a nice added bonus. Experiences So Far
Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing. The metal on metal contact has damaged the powder coating and the frame. I expect a little better QC.
I've only put a few hours on it, so not a ton to report on usage. It isn't quiet; it's silent. I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller. The motor controller is Italian and made by Dana TM4. Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent). The motor is rated at 25 hp and 71.5 lb-ft of torque. It feels very powerful. All the torque is delivered instantly, if desired.
The bed is huge and has an electric dump as standard. Great feature but would like it to go up a bit more. Probably not feasible from an engineering perspective, but I want and I need ;).
Power steering is nice, but vague. Probably common to many UTVs, but I am accustomed to more direct results from input. Plan early and plan often.
In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart. I may get fatter, but I'll also get more done. After a few days of usage, the battery meter has gone down by 1/10th.
Until next time...

Hello all. I have a 2005 Joyner sand spider 650 with the dreaded broken output shaft on the transmission. I got ahold of a 2007 joyner commando 650 for cheap that had a bad motor but a good transmission. I got it because everything i read said that the transmission would work but it seems that it will not. Due to the commando being 4x4 it has a selectable locker and a small ring gear using a "idler" gear to turn the ring gear which make the output spin the wrong direction. Is there any way that I can make this thing work? I really dont want a commando, I like the buggy but if the trans wont work then I can only put my motor in the commando. Any help would be appreciated. I have the ring gear from the original trans but the shaft is broken and the shaft from the commando wont fit the ring gear it doesn't appear.

I’ve been eyeing a Hisun 500 soft cab enclosure upper doors setup for my UTV, but I’m really not sure if it’s a smart move. The idea of doors and some protection sounds appealing, but I worry they might just be a flimsy afterthought — weak zippers, thin plastic windows, maybe leaking or fogging when wet or cold. What good is “protection” if it doesn’t seal well? Also concerned about ventilation: with soft doors, does the cab get too muggy or stuffy?
Anyone here use soft-cab doors on a Hisun 500 — did they actually hold up for real riding conditions, or did you end up ditching them for hard doors (or no doors)?
