Grogg Posted March 12, 2023 Share Posted March 12, 2023 One of my mates who convinced me to buy my first and as yet still to be finished building RC car, has just given me a 1/8 scale truggy - the RC car I bought is 1/10 scale. Besides size is there any differences between 1/8 scale and 1/10 scale, does one handle better than the other, is one faster - I can't imagine it being the 1/8 if so as all the engines I've seen for them have a lower KV than the engines available for 1/10 scale, is one more durable, easier for newbies? 1 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted March 12, 2023 Share Posted March 12, 2023 the 1/8th will more than likely be faster than the 1/10th and will go over rougher ground as well what 1 did he give you ? 1 Quote Link to comment Share on other sites More sharing options...

He gave me the HoBao Hyper Cage Truggy that he bought, forgot he bought, then bought another one of. It's missing wheels that I think it originally came with - I have no wheels for it and he didn't give me any with it, and it needs an ESC, engine, servo, reciever, and more than likely different batteries than I bought for my 1/10 scale to make it ready to use, so one order away from being a usable RC with next to no assembly required. 1 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted March 12, 2023 Share Posted March 12, 2023 this should be a good combo for it https://www.modelsport.co.uk/product/hobbywing-cml-ezrun-max8-with-2200kv-motor-combo-397267 possibly with a 17 tooth pinion and it should go well on 4s the esc will take 6s but prob better sticking to 4s to start with 2 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted March 12, 2023 Share Posted March 12, 2023 Also selection of truggy wheels here https://www.modelsport.co.uk/wheels-tyres/wheels-tyre-sets/truggy-stadium/18? it should be 17mm hexes 1 Quote Link to comment Share on other sites More sharing options...

No idea, I'm still building the first RC car I've ever had. All this one needed to complete ''assembly'' was to use 2 screws and 2 spacers to attach the rear wing, I've no idea why it's rated as a 4 out of 5 for difficulty on Modelsports. Including the rear wing and wheels there's probably less than 20 screws to do up to turn this thing into a fully functional rc car once you have all the needed electrics.

Nitroholic Posted March 12, 2023 Share Posted March 12, 2023 KV is no way to judge speed. All KV tells you is unloaded motor revolutions per volt. If you run a 2000KV motor on 6s ..... and compare it to a 5700Kv on 2S ....you get about the same revs. The amount of power generated though, is hugely different. The 1/8 buggies are usually running ESC's rated to 100-150A. Wheels are easy. It's not like a 1/10 touring car, where many options are available to fit under the shell. Monster truck and truggy wheels come in 2 varieties. Half or zero offset. Your manual isn't specifying wheel dimensions, as it doesn;t really need to. You can see from the pictures of hte stock wheels that the wheel nut is recessed. Zero offset wheels have the wheel nut sitting proud. You DO NOT want zero offeset, they will come too far in, foul the steering and cause issues. Any of the others will be fine. 2200Kv is about as far as you can reliably go with a 6S setup. It's on the limits. 8S would be pretty much undriveable, and unreliable. It's not worth it. More is just not better unless you can get teh traction, and want to have the diffs usable for more than one run. Did it once...slapped the biggest motor I could fit into a Hyper St truggy, planned to run 6S. Couldn;t keep the diffs together, tyres ballooned so badly I couldn;t keep them on the rims and all it did was wheely and crash when it did run. Then it cooked the ESC. Probably from over-revving when the diffs failed. 2 Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted March 12, 2023 Share Posted March 12, 2023 Wasnt the Caged based on the Hobao SSTE? 4S-6S is best for 8th scale. 8S is too much IMO. I think youll be amazed how ridiculous the performance of an 8th Scale Buggy/Truggy on 6S. To give you an example heres a Maxx which is a big 10th Scale, a Sledge (which is a “big” 8th Scale, that runs on 6S, compared to an X Maxx which os a typical 8S vehicle.

Yrkoon Posted March 12, 2023 Share Posted March 12, 2023 (edited) 1/8 scale systems are lower kv for the extra torque and the motors are much larger than the tiny 1/10 scale ones, they are by no means slow 2200kv is pretty fast for 8 scale, infact my fastest car is a 1/8 hyper 7 on 4s but it can take 6s i converted to electric from nitro with my hyper 7 🙂 Edited March 12, 2023 by Yrkoon 1 Quote Link to comment Share on other sites More sharing options...

I think you're right about the caged being based off of the SSTE, the physical manual, not just the online one, contains the instruction for it as well as another Haboa RC and the caged truggy. 11 minutes ago, Yrkoon said: 1/8 scale systems are lower kv for the extra torque and the motors are much larger than the tiny 1/10 scale ones, they are by no means slow 2200kv is pretty fast for 8 scale, infact my fastest car is a 1/8 hyper 7 on 4s but it can take 6s i converted to electric from nitro with my hyper 7 🙂 I'm not really sure on what engine and esc I want to use yet, the only thing I'm sure of is that I want to stick with Hobbywing as I have the Bluetooth thing to connect the esc to your phone to adjust a whole bunch of parameters on it, and I'd prefer it to be sensorerd. I figured 8s was a good idea based on the size of the thing - it's more than twice the size of the Tamiya Rock Socker, it's surprisingly heavy most of it is aluminum, and it has a ''warning this is not a toy'' warning on the box and in the manual.

Yrkoon Posted March 12, 2023 Share Posted March 12, 2023 (edited) hobbywing max 8 bud, good bit of kit i have the 2200kv combo in my hyper 7, and my corally kronos has a rebranded max 8 combo. hobbywing max 10 is 10 scale and hobbywing max 8 is 8 scale etc i have a few of the ten scale ones as well and they never skip a beat, pure quality 🙂 https://www.modelsport.co.uk/product/hobbywing-ezrun-max8-g2-esc-combo-with-4278sd-2250kv-motor-1347107 something like that 🙂 yeh the heavyness of 8 scales is why the kv looks low more torque but they run on 4-6s so more voltage and gets the speed up,plus the sheer size of the motors 🙂 5 scale ones are the size of coke cans lol Edited March 12, 2023 by Yrkoon 1 Quote Link to comment Share on other sites More sharing options...
