Feel free to post. I just don't want this thread to turn into a p***ng contest.

Better quote? LOL

I have a question about the RX8 Gen3 functionality with the hotwire 1 via android / cell phones. I have been using my phone/hot wire 1 on all my Gen2 RX8's,RS & RSX ESC's without any issue (currently running 258 firmware on all). I tried to make adjustments to a new Gen3 RX8 and the hot wire app will only will go to demo mode. I then connected it to my desktop pc and it recognized the ESC and allowed me to make changes as expected. I then tried connecting to a few of my Gen2 ESC's to make sure I didn't have an issue with my phone or the hotwire 1 and they all still connected and functioned without issue.

Is the hotwire 1 no longer compatible with the Gen 3 ESC's via android? and any ball park timeline on the hotwire 3 release?

We've all been waiting for this answer. 😔

The Hotwire 1.0 and the RX8 Gen3 are compatible. You may have to go to the Google Play store and get the newest app. This should fix the programming issues you are describing.

Hi,

i've got myself a GEN3 on the way and was wondering what recommendations others may have for a motor to run on 6S for bashing in a TLR 8IGHT-E 4.0?

I was going to go the 1900kV / GEN3 combo but at the last minute i found out by the specs that this motor isn't 6S compatible.

Would the HobbyWing XERUN Sensored 1900KV G2 be OK with the RX8 GEN3 ESC?

I run the T8 Gen 2 1350kv on 6s.

The issue with a 6s 1900 setup is gearing. You won't find the right gearing unless you're trying to do top speed runs.

On 6s the 1400 is an ideal choice.

Thanks for the info Randy.

Could you define what you mean by "the right gearing" ?

I'm aiming to have a wide range of RPM to have at my disposal but without going to extreme in the top end. For example, a friend has a 2250kV motor on 6S and its SUPER touchy at first throttle/low throttle but hammers in the top end (naturally).

I would have preferred to get a Tekin so the motor works well with the ESC but if they aren't actually compatible with 6S then it rules out even trying them where as the HobbyWing at least is capable of 6S and its only gearing i'd have to really worry about.

I've looked on the website and its not clear if even teh 1700kV T8 GEN2 is ok ot run on 6S. If i go to low then i wont have much top speed (but i'm coming in totally blind to what is acceptable as this is my first -E 1/8th and i'm trying to not waste money with trial and error).

We generally recommend motors that can get into the gearing range the cars were designed around. It's not so much that the motor isnt' capable, rather we've seen so many people not understand gearing and kv together with the battery voltage to understand what's going on.

The 1700 can run 6s, but you must gear the car correctly.

For example you're using a 1/8 buggy which was primarily designed around a nitro .21 engine. Those engines spin between 5,000 and say 45,000 topped out. Knowing that you can see why having a 6s 2250 setup in one creates the issue where the 56,000+ RPM. See the issue? The extra 11,000 rpm doesn't seem like much but the gearing will need to drop into the 11-12T pinion range. It maybe possible but you'll be much better served long term with a lower kv motor on 6s, such as the 1400 or 1700; 35,000 and 42,000kv respectively.

1/8 cars were never meant to hit speeds of 80+ MPH. The cars aero and other features hold it back from these speeds. I know it's fun as heck. Generally we also see guys skimp on the batteries and try to run inexpensive packs with less than true 40c which can over work the ESC under these loads.

I hope this info helps.

Thanks for your response Randy.

I'm quite familiar with these aspects so this isn't an issue (years of electric heli, 3S to 14S). My issue is that i can't find full motor specifications so i can be informed about what maximum voltage i can safely operate each motor on (amongst other things like max wattage etc etc) and hence can't then decide which motor to get to suit my application/intention.

OK Thanks for that information. Perhaps i'll jump down from the 1900 to the 1700 and start there. Although the 1900kV was where i was hoping to jump in based on my current numbers.

lol yeah i'm only going for the 'fun as heck' as i'm only bashing. I'm not doing any speed runs or anything like that. Although i can see us GPS'ing them to see what they may be capable of as a relative comparison between mates only. Its just offroad bashing and my OCD engineering/technical mentality that i like to cover as many of my bases as i can prevent myself from being unhappy with in the future!

I haven't seen to many true 40C LiPo batteries from the data i've seen (given how LiPo's come out of very few factories, i'd assume this is echo'd in the car battery sales as well). And unless i'm missing something, how does a battery that can't supply large amps due to not living up to its rated marketing sticker, "over work the ESC under these laods" when it won't be able to actaully supply large loads? What am i missing, what is your meaning here?


Thanks again.

Just order my first tekin ESC rx8 gen 3 would buy the hotwire 2.0 or just wait the new hotwire 3.0?

Fun is heck is fine, just be aware of the limitations of the setup. While I agree that a lot of batteries may not perform as rated, what we're looking for is people not to rely on "burst" ratings. A 20c lipo can damage the ESC due to not handling the load and creating serious amounts of "ripple" current that the ESC must deal with. Too much of this is of course bad and creates a lot of heat.

Good batteries hold up to the loads with less ripple current creating a lot less "work" for the ESC.

Up to you. If you're an iPhone user wait for the 3.0.

Thanks for your reply. Yes I am iPhone user do you know when is coming out the 3.0?

The Hotwire 3.0 is going out to distribution shortly.
