champ222 Posted October 16, 2023 Share Posted October 16, 2023 Hi All Ive bought a new unbuilt B74 kit (not .1 or .2) from ebay for a good price. I love building kits, but its largely either Tamiya, or pricey race cars. I dont race, so cant justify the cost of those kits, just for something to build. Anyway, i'm going to need a few bits to finish it off. I'm not racing, but i wouldnt mind if it was proper quick 😊 Motor - I have a Hobbywing EZRUN 3652 SL G2 4000KV from a Max10 combo. I could use this for a while, but i'm tempted to try out a sensored motor, just because ive not tried one before. ESC - The ESC from the max 10 combo mentioned above, is the 60A one. Its currently in an LC Racing LC12B1. i could move it back out of that and put it in here, but would the 60A be too limiting? - i could go Hobbywing 10BL120, and run the motor above, and switch to something sensored later if i wanted... any better options that are similar ish in price? New Max10 G2 80A does sensored, but seems to have its own connector? Servo - I have a Hobbyking something or other which will do for now. Battery - I guess its Shortys for these? some low price options on Hobbyking, but all out of stock. Cheap ones from model shops start around £30+ a few used options around, but i'm not so keen on second hand lipos. any suggestions here? Thanks guys Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted October 16, 2023 Share Posted October 16, 2023 You could have a look on Amazon for lipos Quote Link to comment Share on other sites More sharing options...
lorrylemming Posted October 16, 2023 Share Posted October 16, 2023 My suggestions for a budget electronics set. ESC: https://www.modelsport.co.uk/product/hobbywing-quicrun-10bl120-sensored-425021 Motors: https://www.modelsport.co.uk/product/speed-passion-1-10-competition-mmm-series-45r-bl-motor-407412 https://uk.banggood.com/Surpass-Hobby-Rocket-540-Sensored-Brushless-Motor-V3-Shaft-3_175mm-RC-Car-Part-p-1188086.html?cur_warehouse=CN&ID=6314546&rmmds=search https://www.modelsport.co.uk/product/core-rc-star-fixed-timing-motor-105t-1345031 4.5t will be very quick, 8.5t or 10.5t will be more sensible. Batteries: https://chinahobbyline.com/collections/uk-warehouse/products/cnhl-racing-lihv-series-5200mah-7-6v-2s-120c-hv-shorty-hard-case-lipo-battery-with-ec3-plug?variant=43988817641686 I have three 10bl120s, all working well. I also run one of the surpass motors and a few CNHL batteries, again pleased with them. Quote Link to comment Share on other sites More sharing options...
champ222 Posted October 16, 2023 Author Share Posted October 16, 2023 Thanks for that. I was looking at the speed passion motors today, but i think the 4.5 was on the limit for the esc. As you say, the others might be more sensible. Apart from them being sensored, how would they be, performance wise from the hobbywing 4000kv motor i have now? Ive also been locking on that site for lipos, though not those ones specifically, so i was on the right track i think Thanks Quote Link to comment Share on other sites More sharing options...
lorrylemming Posted October 16, 2023 Share Posted October 16, 2023 https://www.rccaraction.com/brushless-motors-turns-vs-kv-rating/ This site has a rough conversion between turns and kv but its not exact. I'd also look at an additional fan for the motor if you're going to run an entire pack at a time rather than 5 minute races. With 4WD the car will create quite some heat and a buggy shell doesn't let air through for cooling. This is the part with a fan mount for the 74.1, not sure if it fits the previous model. https://www.dms-racing.com/spare-parts/spare-parts-for-associated/low-profile-battery-posts-fan-mount-and-esc-tray-ae-b74-1-detail Quote Link to comment Share on other sites More sharing options...
champ222 Posted October 17, 2023 Author Share Posted October 17, 2023 Great, ill check out that fan mount. Ive seen the charts with Kv vs turns before, and realise its just a guide. Although, even comparing turns to turns, or kv to kv, i dont have enough experience to know what difference 4.5t vs 7.5t would make, or what 3500kv against 5000kv would be. All my models are different scales, and since i dont race anyway, i just pick up something used/cheap. Ill do some more research on the subject.

Alex97 Posted October 17, 2023 Share Posted October 17, 2023 Your Hobbywing EZRUN 3652 motor would be fine. You don't need a sensored system of you just plan on hooting it around. I'd buy another MAX10 G2 ESC and just use that. Unless you can solder then you might struggle to solder up the motor and ESC so having everything pre soldered will help you. It won't be the best setup out there however for hooting around you'll be fine. Quote Link to comment Share on other sites More sharing options...
champ222 Posted October 18, 2023 Author Share Posted October 18, 2023 Thanks Alex Soldering is no problem for me, so i could go either way. £50 Max10 G2, 80A £72 Max10 G2 140A £45 10BL120 - sensored or non sensored £52 10BL120 G2 - non sensored only, (which seems like a strange move), waterproof and does 4S (which doesnt really help me) its bigger too. The £45 option looks like the way to go to me, but there isnt really a lot in it price wise. While any of them will likely be fine, obsessing over the details is part of the fun! 🙂 Quote Link to comment Share on other sites More sharing options...
Alex97 Posted October 18, 2023 Share Posted October 18, 2023 10BL120 is a solid ESC for the money Quote Link to comment Share on other sites More sharing options...
champ222 Posted October 19, 2023 Author Share Posted October 19, 2023 Yeah, it seems like it. I'll likely go for one of those i think Quote Link to comment Share on other sites More sharing options...
