I have trouble connecting with the app. Must activate location on phone. Once in a while it will connect. Managed to change settings to brushed mode, calibrated throttle, but the settings dont really make a difference, maybe for brushless but not brushed. Was good for a day, then motor started stuttering. Updated to 2.6 firmware but the drag brake was inoperable. 2.3 and 2.4 drag brake works but light wont turn blue and power the receiver until i move the drive shaft. Full of bugs. Supposed to be fun with RC but stressing out instead. Furitek is no help, they just said "uninstall your current app and install the latest version. Check also your bluetooth connections, maybe loose". One time it sparked when i connected the battery, and also light never turned blue (bootloader mode) until i waited the next day and tried again. I do not recommend. All the good things about this product on youtube is a lie. Disappointed in Furitek. But, Nick P. was great customer service.
Update: Furitek communicated with Furitekusa and sent me a Iguana Pro (brushed only). I was wrong, their customer support is very good. I can trust Furitek brand, will look into other products from them. If you have problems, go to the main furitek website and create a ticket, they will respond. Thank you Adrenaline RC, Furitek, and Furitekusa. Trust Furitek, they made me satisfied 100%
