VRD Stubby Kit Motor and Gearing

[JatoTheRipper]

I am leaning towards eventually removing the Fusion Pro in my VRD Carbon and installing a stubby kit with short Revolver motor and AM32 ESC. This is just to get the discussion started as I have not even painted my Stance body nor have I gotten the truck out on the rocks or trails at this point. I am leaning towards a small-capacity 4S LiPo battery. Which battery, gearing and outrunner motor including KV are you using with your VRD stubby kit?

I see where you are going ... sporty style inspired VRD carbon .....yes I am in!!! and currently stashing everything for my build ... so Far I have a VRD Carbon, Stubby kit, Holmes Team Spec 1900 Revolver and Crawlmaster mini V3 for it. I see a lot of folks jumping on the 4s wagon unfortunately I don't have a charger for 4s or batteries themselves. I been running Tattu's 850 and 650 small 3s 75c and 100c packs and happy with the results. The plan is to gear it down and make it as light as I can for fun.

I think the Holmes 540M is about as big as you can go. He's got them available in 1800kv right now. Holmes occasionally runs "Team Spec" motors that are a little different. I'd think the 2024 versions should be out within the next few months. Currently I'm running an 1800 Team Spec in my Trail class (C1) and a 2250kv Team Spec on my Modified (C2). Both on 4s. I prefer the 2250 with the extra wheel speed. I have several friends running Yellowjackets and they are happy with them.

The 80 amp Rhino ESC is hard to beat for the price. The only thing I do not like about it is the size. They're pretty big. The Silent Assassin/Exo Belay/DLux S2/Slite are a good bit smaller but they do not have as robust of a BEC. I dont think they advertise the Rhino as being waterproof but I dunked one of mine and it did not hurt it.

As for what size battery, that would depend on how comp courses are setup. Here, most are 6 minute time limit. I'm mostly running Tattu R-Line 550mah packs. Thats more than enough juice for two or maybe three 6 minute courses. I typically change them out between courses but like having the extra capacity because sometimes you gotta run two courses back to back and dont have time to swap batteries. I have a couple 650s for the 30 gate comps.

Low center of gravity is my thinking for the switch to stubby. Which body do you plan to run?

I forgot to mention asking about KV so I added it to my original post. That's really the big question. I like wheel speed, but I want the best low-speed control possible.

How many cells are your 550mAh batteries? I don't comp at all and never plan to do so. I will be taking my truck to play on rocks and possibly even the trail so I wouldn't want to go that low, but I'm thinking an 850mAh 4S battery.

4s on both. I don't have much room for batteries on these trucks so 650 is about as big as i want to go. Havent really timed how long they run until cutoff since i normally change them out long before then.

yes that's the intent. I have been wanting to build a F250 tamiya cab and I think this would be the perfect opportunity with some straight axles on it to bring it even more down and low. Then make it easy to inter-change the hardbody with ease for a Redcat-Kaiju lexan body for a little more adventurous and spirited crawling.

I don't comp or plan TBH ... Pretty busy with the daily stuff, family and work. I like and enjoy building trucks and wrench on 1.1 things to keep my young boys learning how to use their hands to build and fix things. But I do try to ZEN-OUT and run some battery packs throughout the whole RC collection in the evenings and weekends.

Here is a comparable build I did a couple years back. HH/TGH Sherpa chassis very similar to what VP offers in the carbon. (same axles I stole from a Phoenix kit). I want to make the carbon build lighter and better CG with the VFD and Stubby kit.

I have a roller with the VRD skid and stubby setup, Its gonna be my next buggy build.

I used a HH 2023 team spec 540M 1800KV and a 13T pinion with the standard 56T spur gear. I plan to run it on 4S. I'll be using the HH Crawlmaster V3 ESC.

I've only run it inside so far but its geared fairly low.

When I grabbed the VP stubby kit I didn't look at the description at all. I ordered a non revolver stubby only to find out that doesn't fit as laid out clearly in the product description
So don't be stupid like me read folks.
