Gear Speed - Brushless RC Speed Calculator App Comments & Reviews

Gear Speed - Brushless RC Speed Calculator Positive Reviews

Good tool, could use an updateGood tool but lacking some basic things that would take it from good to great. There’s no way to reorganize your list, which would be really nice to group models together with different gear and tire setups. I’d really love to see a master car list with a sub-list of available gear, tire, and battery options. As a quick and dirty tool, this gets it done..Version: 2.1.0

Very usefulVery useful but could be a little better. Using this for drag racing I am pulling down to 3.4 per cell and I can’t duplicate that..Version: 2.1.0

Needs workI'm only giving it 3 stars because I tricked it to work. Need a way to set differential gear ratio. I tried calculating speed of new xmaxx. Found several calculators that work great online and figured I'd try the app. The only way I managed to get the app to produce close to accurate speeds was to set cell voltage to 3.75 and cells on 2. I'm appalled that I paid for an app that isn't actually accurate when it's marketed as a calculator..Version: 2.1.0

Great Trackside Tool! 👍🏼🔧It's accurate, easy, and intuitive. Make trackside gearing decisions with confidence. No problems at all from download to everyday use, it works like a charm. For those of us old-school guys, the email and export features make keeping a hard-copy record easy to do..Version: 2.1.0

The best for speed runners in the rc worldIt’s just the best app you can possibly get to do your gearing for rc cars and you won’t find a more accurate app out there anywhere i’ve looked it’s worth the money.Version: 2.1.0

I guess it works kind ofIt doesn’t state what size can the motor is or what type of pitch the gears have and there is no way to change it. It doesn’t even say what the can size is that the entire app is based off of. If they would fix this it might be worth something but I guess.?.Version: 2.1.0

Pretty good App.Great for seeing how gear adjustments can effect overall speed. Useful as a good guide for the numerous variables that contribute to performance..Version: 2.1.0

So soWhen you put the information in it sometimes safe stay information I went to a big race put information in what I had the next day it was totally gone.Version: 2.1.0

GlitchesYou put everything in correctly but it tells you your car will only do 3 mph. The app hasn’t worked right in a day now.Version: 2.1.0

Great appDrag racing guys need lower value of battery power to calculate speed 6-7v realistically.Version: 2.1.0

Great appI love that I can save multiple setups and add notes to each setup. Worth all 99 pennies.Version: 2.1.0

Great toolExcellent tool for the RC enthusiast. Only downside to using the GEAR SPEED app is that it can be pretty addicting..Version: 2.1.0

GearsGreat apps definitely takes the guess work out of things👍🏾👍🏾👍🏾👍🏾👍🏾🦾.Version: 2.1.0

👍🏽👍🏽Great App!!!!Great app if you type the exact number your gonna have what you want.Version: 2.1.0

Why all the bad reviews?App works great for me. Arrma 6s Talion running 8s on GRP’s and castle MMX8s/ 1717-1650kv. I don’t know how the app looked before the last update but everything is there to calculate speed (theoretical). That’s the only problem. According to Raz Shiffran you should input 1 cell less that whatever you’re running. Also, drop your cell voltage to around 3.75v per cell if you want a realistic number. Also, make sure when entering in your tire size that you know which unit of measure you’re using. I’m pretty sure that’s what one reviewer did wrong. He said it calculated his rig could only achieve 3mph. Probably entered his tire size in inches when he was using the millimeter unit of measurement. Imagine a 4mm tall tire, LOL! App does what it says. Wish you could enter in air resistance and maybe the dimensions of vehicle..Version: 2.1.0

Works Great For Me!I’m new to 12th scale and this app works just fine.Version: 2.1.0

RcCool app definitely helps alot.Version: 2.1.0

32p and 48p is differentThis app should have different gear pitch types.Version: 2.1.0

PerfectWorks as intended!!.Version: 2.1.0

V/CellThe “V/Cell” won’t go higher than 4.30 “V/Cell” ? Need it to go HIGHER THAN THAT..Version: 2.1.0

Great app.Love the app.👍🏾.Version: 2.1.0

Great Gearing AppLet's start with simple interface, nice and clean. Easy to see in bright daylight in the pits. It gives you what you need to know to get your RC car to where you want to run, gearing wise. Driver skill is a different story. I'm impressed for the cost (free at this time) and will recommend it to other racers..Version: 1.0.0

Great appGreat app simple to use and pretty accurate if you compare it to doing the math yourself only complaint it doesnt go to 34 volts so i still have to write out my 8s set ups.Version: 1.0.0

Easy to use appVery nice to look at and simple to use but it doesn't let you input a KV less than 500. That is something I would like to see updated very soon, as I would like to calculate with a 190kv motor..Version: 1.0.0

Great app!This is a very easy app to use. Works great and does exactly what you want!.Version: 1.0.0

Just okWhat about pitch size?.Version: 2.1.0
