what does the extra tall rear upper link mount gain you? I was thinking about building a sporty from rhino with some cheap china scxII axles I ordered but it would put the upper axle link mounts directly on top of the pumpkin. would that be terrible, or even possible?
Theoretically, it should help with torque twist on steep climbs (keep from rising one of the front wheels), but besides that, on flat ground at low speed, it doesn't matter much. Another advantage is that it should keep the car more planted, especially on sidehill. In any case, it is generally better to have a higher mounting point on the axle than on the chassis/body for the upper links.
Thank you! I wrote my shock setup in the description if you are interested. 25% underdrive in rear axle. I like your nick, reminds me of the time I played UT 😆
You can buy an RTR version on Aliexpress, with the RhinoRC wheels/tires and electronics, I don't remember if it includes radio system and batteries though. I bought the kit which included the body, links, gearbox, drive shafts and axles. I put my own shocks, wheels, foams, tires and electronics. About the wheelbase, yes it's a bit longer than the Bully, in my setting for both of these models, I measured about half an inch difference.
I just ordered a similar set of wheels and tyres because I like the look of yours (hope you don’t mind). But I went for the injora set, so it’ll be interesting to see what the quality is like!
I'm not sure about the link riser. Theoretically, it should help with torque twist on steep climbs (keep from rising one of the front wheels), but besides that, on flat ground at low speed, it doesn't matter much. Another advantage is that it should keep the car more planted, especially on sidehill. It is not an expensive part so I thought I would give it a try but I did not do any comparison with and without it. About the roof, I just photo-printed an image, cut it according to the shape of the roof, then glued it on top and also put a special colorful decal that shines and changes colors when light hits it 🙂
@@driverc4357 what made you go for the 90mm desert lizards?? I know that the standard shocks are 95mm, so was wondering if it’ll be best to go bigger or 90mm same as you have??
That's a good question 😄 I actually wanted to buy Dravtech shocks for it, they are 92mm hole to hole. I put them on my Bully a long time ago and they really work amazing! But nowadays, unfortunately I don't find them anywhere. Desert Lizards are very good shocks with tons of configurations out of the box (different springs and lengths, etc.), and they are available at many places so I decided to go with them. I think that for the Rhino, anything between 90mm and 100mm will be good. The chassis has many mounting holes, a shorter shock will probably be better mounted on the holes closer to the edges while longer ones can be mounted on farther holes, the flex would be more or less the same in my opinion. Remember, it's a shafty, so you are a bit limited by the shaft itself (it can just pop out or you can reach a bad angle that can cause damage to the universal). I'm currently in process of testing different shock setups, I don't like the very limited flex that I have right now, I will upload a video with my improved shock setup soon 😊
I have to disagree with you about the links, I think that they must be as close as possible to each other at the body while as far apart as possible at the axle (I mean the lower links). About the shocks, I did notice a few problems, the main of which is very low overall flex which is bad in some situations. I will change positions and springs setup, will test it soon 👍
Im looking into a comp shafty crawler, eyeballing both of these rigs for a long time, of course bully being in the shafty form not moa, for the price differences which do you see coming out on top
What is a Bully in shafty form? Bully body and links but different axles and a custom gearbox? :) I can just say from my experience, both are very capable. But if you want specifically a shafty, then the Rhino is a great choice. It's practically a kit, so you don't have to find and match parts. It has a low CG in the body which is great, it has portals which gives more clearance and gear reduction, It's a bit wider and longer so maybe a little plus there too. However, due to universals in the knuckles, the steering is a bit less than the Bully axle with the XVDs, but universals are tougher to break (although I never broke XVDs). Some challenges are easier with the Bully, but that is due to its MOA properties (I believe), some others are easier with the Rhino.
The Bully has only ~1.2cm shorter base than the Rhino in my current setting, some will say it's a world of difference, but I'm not entirely convinced. No doubt, making it longer will benefit it 😊, but not sure at all if that provides superiority to the Bully 😉. About weights, I think the Bully is overall better balanced, you may see on some descends that the Rhino barely makes it without flipping (and once it even flipped), that is because it has much more of its weight on the front than the Bully, so here for example the Bully excels. On the other hand, the Rhino doesn't drag a heavy motor on the rear, and my links and shocks setup make it more planted. So it does better on some steep climbs and side crawling. In any case, I agree that the Bully can potentially win due to its versatility, but it does have its shortcomings too 😋
Actually I noticed that I did trim a bit the turn angle of the servo, so the axle can physically give a bit more turning angle. In any case I will be changing the drag link and will make sure the steering angle is set to maximum next time. It's an overall great axle, so you shouldn't be disappointed :)
What foams are you testing with the tires stock foams or crawler innovations 👍🏻🔥😎🔥🤙🏻😂😂 I see you cut some of the knobs also on the tire nice pattern there. 🔥
Cool video! I was kind of feeling weird because I take my Bully2 to the forest and the use I give it is more "trail and climbing" than pure rock crawling. There are not so many rock formations where I live thus explaining why. I think I will make a video in the trail soon. Thanks for sharing!
