You can't judge a phone ( or computer or anything really ) by specs alone. The only way to judge them is by using them. Do a Google search on the make/model and see what other reviewers are saying about it and read more than just one or two so you can get a consensus.
Things to consider but not really something I'm concerned with since I have no experience with several things, I'm just bringing them up. There will be no way to tell if the Align app works well or not... or more importantly ( since the app relies on it ) how compatible the bluetooth connections are. This is a T-Mobile phone that is designed and only sold by them so the phone may only work with their network and may not transfer to another provider should you get tired of using their service. I suspect ( I can't emphasis that more ) that it's a budget phone with decent specs that will generally work well but you may have minor issues with some parts of it. Fingerprint readers and cameras are the typical areas that are often skimped on with budget phones. I'd also ask what version of Android they currently have installed ( the webpage didn't list it ) and how many upgrades is the phone planned to get.
A downside to every smartphone I've seen... battery life. You will likely need to charge the phone every day/night or two depending on your usage. Like your RC stuff, battery care and life is similar. Typical battery life is in the 3-5 year range. Don't keep your phone on the charger, it's hard on the battery, so charge it up and take it off when full. I do top mine off every morning to make sure I can get through a busy phone day if I have one.
Google things to note. This is an Android phone and as such, will likely require a Google Account to setup. If you already have one, make sure you know your password. If you don't have one, go ahead and set one up ahead of time ( and don't forget the password ). Once that is setup, you can make your life a little easier by logging into Google on your PC's browser and then go to the Google Contacts to setup all of the people and phone numbers you currently use. You can place friends, family and businesses into their own category ( they call them labels ) and even have them in several categories if you wish. Photo's you take with the phone can also be automatically loaded up to their Google Photo's website for you to access from your PC if you wish ( it is optional ), these are private unless you select to share them. Google Calendar can also be setup so you can access it from the phone or your PC. If you set your contacts birthdays or anniversaries up in the contacts area, they will show on the calendar also... and of course you can set appointments and to-do's up there like most calendars. Google Drive is also available to share other files between your PC and phone if wanted. Bookmarks you have in Chrome ( if you use it and are signed in with your Google account ) can also be accessed from Chrome on the phone if you wish.
Handy Google links... just the ones I mentioned, they have many others.
contacts.google.com
calendar.google.com
photos.google.com
drive.google.com
Google uses Gmail for the email account which you can access from the phone or PC as well.
