Thanks, I'm a newbie and got my Grasshopper kit yesterday. I will build alongside your video instructions. Just ordered the bearing kit and it will be here in 2 days I guess.
Awesome! Welcome to the world of RC!! I'm sure you're going to enjoy the build process. Definitely a fun buggy! If questions come up along the way that for some reason I haven't addressed be sure to reach out...happy to help.
I’m a fan of futaba products so I would go for the S3004 servo if on a budget or the S3010 high torque ball bearing servo if you want a servo that can really handle chassis steering bounce. But the S3004 will do the job adequately. As to the ESC the equivalent one to the Tamiya TBLE-02 would be the HW1060 (hobby wing) This ESC now comes with most Tamiya kits in the USA. It is also pretty affordable.
@@FastFreddyRC Thank you for your help.I couldn’t find futaba s3004 or s3010 servo in Australia, however s-u300 and s u-400 sold in Australia. Can I use S-u400 servo for grasshopper?
You just need a standard servo for the grasshopper. I wouldn’t go crazy. There are high torque servos but the grasshopper doesn’t need the torque. I’m a loyal Futaba fan so I use S148 or S3003. Either will do the job well and depending on where you are in the world you’re looking at $20 or less. Also Tamiya manuals often mention futaba and sanwa servos so for ease of following along in the manual it might be a good choice for you.
@@FastFreddyRC So, I'm more interested in the movement range. I see a lot of 180° and 270°. I would have thought both of those would be too far. I would have thought 90-110° would be realistic. Maybe it's normal to get a 180° and let it stall out, but then you have to consider the stall power draw. Does that sound right? My quick search this morning resulted in many discussions about torque and speed and 40mmx20mm "cage" size and metal gears and body vs plastic, but none about the full deflection angle.
@@CollinBaillie The 180 is correct and you don’t need more than that. Some servos, including those for boats and planes, can do more for certain applications. But MOST steering applications you want 180 movement. I think they say 180 because from neutral the servo can move 90 degrees in each direction.
@@FastFreddyRC I was also thinking it's related to the PWM duty cycle? These seem to be rated for 180° from 500us-2500us. From what I've seen, the tx/rx sends 1000us-2000us, so you wouldn't get the entire 180° of motion. But no one talks about this.
I used an older battery that I had on hand for this video. However, my newer batteries are the same. It’s a 7.2V NiMH. Here is an example: www.horizonhobby.com/product/7.2v-2200mah-7.2v--nimh-tam/GEANM22006ST.html

Very good presentation Freddy, you set the importatnt points on highlight👍
Thank you. Appreciate that RC Birds! Certainly was hoping for that.
Iconic you said it. Good video Freddy. You've become a Tamiya guru, shout out to ole Frank Evans as well 😉
lol thanks Thomas!
Very cool! Perfect video for a beginner or someone thinking about getting into the hobby!
Thanks Addam! I’ll definitely be spending much more time on things than normal. The Grasshopper seemed like the perfect kit to do that with.

The grasshopper sold in Australia not including ESC and servo. Any recommendations about ESC and servo？ such as brand and serial number? Thanks

How do I choose a steering servo? What specs do I need to consider?

What size are the bearings?
You need:
9 - 5x11x4
1 - 5x8x2.5
What battery did you us can you put a link or just type it
