Why all the bad reviews? – Gear Speed - Brushless RC Speed Calculator Review

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.
