Hi all, first time post here and I need some help.

I am about to purchase a 1/10 buggy and there are a few options.
Option 1 - 7.2v 3600 mAh battery with a 3300kV motor
Option 2 - 8.4v 4200 mAh battery with 2726kV motor
Option 3 - 11.1v 3900 mAh battery with 2726kV motor

I calculated that the option 3 would be the fastest at 30192 rpm.

One question I have is - which of these options would run for longer (longest battery life assuming running without stopping until and max recommended discharge)?
Another question I have is, could I just replace the 2726kV motor with a 4800kV or 5200kV motor without issue or is it not a straight motor swap? Also how would the extra current draw affect how long the 3900 mAh battery would last?

If I have posted in the wrong thread please accept my apologies and guide me to the right place.

Option 2 will run the longest but otherwise, more info is needed. Exactly what buggy is this? 3s (11.1v) is rarely used in a 1/10th buggy as are motors rated in kv rather than turns.

I know most folks who get into this want to go fast from the get go but I'd strongly suggest starting with a 17.5T just so you can start learning how to handle the vehicle.

I only just recently got back into this and went with a 6T but within a day switched to a 17.5 just so I could figure out how to drive my buggy properly.

Take the time and put the effort into getting some solid foundation skills and the faster turn motors will easily be more enjoyable !

If you give us some info on what vehicle you're getting maybe some of us can offer some suggestions to start with

Thanks for the help. Here are some specs from the sellers online store. As with most of these online avenues the specs are somewhat incomplete. I also seem to have transposed the motor numbers for option 1 and 2 above.

I think any of those 3 options are going to be equally as bad. It doesn't really matter which one you choose. I've seen people sell complete RTR B5's and 22 2.0's for $200-$250 you would be much better off going that route. Unless you live in a country where that stuff is hard to find.

Unfortunately, I have to agree. The HSP cars are not known for durability and their 1/10th 4w buggies will probably be the least durable of those. They are really toy-grade RC cars masquerading as hobby-grade.

What do you want to do with the car? All-terrain bashing? Track driving/racing? Speed runs in the street in front of your house? We can almost certainly get you into the ballpark with a recommendation for a better, more focused car that, even if it costs a bit more at the start, will cost a lot less and be more fun in the long run.

I see it happen all the time. People want to get an inexpensive car to get into RC. So they get something like this. Then a few days later the esc burns up. Then they replace it with a $50 hobbywing, then they break an arm so they get aluminum arms for the whole car, then other things start to break. Then the servo breaks. Then the battery puffs up, biffs blow out. And they start "upgrading" everything to a point where they have $500 in the car because buying something a little better was out of their budget. I know a guy that has over $300 in a 1/18 scale latrax short course truck.

That's a scary vehicle, I wouldn't want to have to find replacement parts for that.

Hey @bertzz99 - what's your dollar range out the door? Perhaps we can put together something solid for you that'll work for what you want.

If your looking to get a car just for bashing, take a look at the 1/14th scale LC Racing/tacon, their a little smaller, but the brushless cars are fast out of the box and reliable, have had a couple SCT truck for over a year and had to replace one front a-arm and a steering servo, parts are super cheap,the brushlees cars come stock with an aluminum chassis, big bore aluminum shocks and metal gears and full bearings, radio work, but aren't the best, we run 2200 mah lipo batteries and get 30-35 minute run times.

Petem

cost on the LC Racing/ Tacon cars are $170-200 RTR, we got ours from NitroRCX for $170 less 20% on a fathers day special!!

I tried to stay on a budget with mine but it completely went out the door and I decided to just get what I want and not worry about cost! I was driving myself crazy. But one piece of advice is I would see what your local hobby shop has. It sucks to only be able to get parts online. I got a hobao hyper ss truggy running 6s. But if I could buy again would probably get a traxxas
