mmihelic No proportion steering. It's either straight or full lock. It's a toy grade RC.

mmihelic You get 1 battery.

mmihelic RH 1073-SJ has the 140mm tires, while the RH 1093-ST has 110mm tires. These tires are 110mm, if the description is to be believed. They are primarily meant for the 1093-ST. You can put them on the 1073-SJ, but it will just look funny.

mmihelic Yes, it will fit. RH 1635 is the same truck as 1631, just brushless. Check the chassis part number on your truck diagram. It should say P2501.

mmihelic It is brushless. See reviews.

mmihelic @Paul your video is in Russian. I don't speak Russian. Put some english subtitles in it if you want other people to understand it.

mmihelic After 3 months it started to display temperatures over 50ºC. Then after a month it gradually climbed up to show 70ºC for stone cold water. Since the warranty is out on mine, into the trash it goes. Judging by the comments the thermometer has a VERY short life span. I do not recommend it.
