Hi guys, Isaac here. As some of you may know, I recently got a new car, an MT, the SG 1601 brushed (rebranded HBX 16889) about two months ago. I was wondering about the actual speed of this rig, before we go any further, bear in mind, this is a 1/16 scale, brushed (390 size motor) MT that weighs 1.8 pounds, so don't expect 60mph! I searched on YT, I found somewhat limited speed run results on this rig, either the person was judging it by eye, running it in gravel or grass, ect. I came across Perth West Oz RC's speed run video, he got 17.1mph. And yes, the results from the HBX 16889 will be the same as the SG 1601, as they are the same car, save for the color of the body shell.
So, the other day I went to a school parking lot, and did my first ever speed run, with any RC! Since I don't have a GPS or something like that, and didn't feel like spending the $35+ for this, I taped an older Samsung phone to the chassis, on top of the top deck, it fit in surprisingly well! Plus, it all fit under the body shell perfectly!
It was around 40f degrees I think, so the road was colder, and the tires weren't warm either, so if I were to do this again in late spring or summer, expect a speed increase of about 1mph. Also, the weight of the phone probably slowed the car down 1-2mph versus no GPS and using, say, a radar gun. So, what speed did I get, factoring all this in? I got 17mph, so in warmer conditions and without the phone, I'm thinking up to 19mph, which isn't too bad all things considered. I fully charged the stock, small 800mAh Li-Ion battery. I don't think a LiPo would increase the speed, maybe by .5mph, as this car currently isn't drawing too many amps speed running.
So, what do you guys think, do you have this rig or the HBX 16889, and what speed did you get?

Edit: Oh, and I may do this with my brushless Wltoys 144001 as well, except there's no way I'm fitting the phone under the body shell, so I guess I'll have to tape it to the rear wing or something!
