[WIP] Tamiya Hot Shot RC
msk6003 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingLast year I bought Tamiya's Hot Shot RC model. I think it's design is very good since when I was very young so I wanted to buy it and did in Christmas in last year. Of course not just for build and control this model, I wanted to build it as lego model so main reason is for comparison with model I will make. I started few week ago but posted in here now. At first I started on chassis. Surprisingly original model's rear tire can fit in medium racing wheel so I bought 2 set of those tire. I use BW3 and 2 BW motor for 4WD drive. And like original model, both front and rear use mono shock. I know this shock is more accurate with original model but I use those yellow hard shock which is little more common because I want make instruction and post on rebrickable. In this version, drive gear ratio is 16-28, 16-28 3.06:1 But when I test chassis gear starting to skipping on both front and rear. So I rebuilt gear train and make gear ratio 24-24, 20-28 1.4:1 but can change gear ratio to 8-8-24, 20-28 4.2:1 or 28-20-28 1:1 too. And add one more shock in rear for better stability. After fix gear skipping, I built remain body without bumper, wing and light. But now I stopped build more. Cause BW3 keep turn off when I drive model 1m. After lot of trying to fix this, I throw BW3 away and change to PF system with Sbrick.(2 L, 1 Servo, 1 rechargeable battery) Now it can drive more but to much slow and don't have much torque.(gear ratio is same 1.4:1) I need to find other way for drive this thing. Than I will finish it's bodywork.
