What are the off the shelf parts the chassis could be made from? Are you hiding something?? A 30" diameter Octapod would be quite interesting, and the 1/4 scale servos are quite powerful… I must design a 30" round hexapod and octapod chassis.
This is not required. The 1/4 scale brackets can be used with ANY current SES bracket, including the HUB-08, AHC-01 (square hub), AHC-02 (5 sided square hub), and AHC-03 (hexagonal hub).
You’ll have to wait until the product’s online, but you don’t have much longer to wait. We should have the ASB-201/B (Multi-Purpose Bracket) and ASB-202/B (Short “C” Bracket) available within a few days or so.
i remember evo making some 1/4 scale brackets which turned out awesome and had some great capabalities, i can only imagine the possibilities with these 8)
Sorry, seems I’m spreading a bit of misinformation here. I’ve corrected the product descriptions.
These brackets will fit the HS-755HB, HS-755MG, and HS-5745MG servos, which Hitec classifies as “quarter scale”. The HS-805XX servo(s) will not fit, as they are “mega quarter scale” and thus are larger.
The 805 uses a different final gear spline than the 7xx ones. So it does present more of a challenge. Honestly I can not say for sure if it will happen.
I just read the forum quickly.
I notice that the C Short bracket is coming soon.
How about the long Bracket.
Also, I did not see
Injection Molded Servo Hinge for the 1/4 scale servo.
Are they coming soon too.
I just assume when you have the C bracket, you are going to sale the Injection molded servo hinge at the same time.
I am waiting for the ASB-202 parts to be received before I design the longer version.
I have not made a commitment to make the injection molded servo hinge for the mega scale servos. They are not required for use with the ASB-201 / ASB-202. They are mostly required for custom lexan part applications (like the RH-01) which are not currently being developed for this servo.
What, if any, are the advantages of using the larger 1/4 servo over a smaller servo with the same torque rating? It looks like it would create a more stable base, but I am curious as to any other advantages.
I initially tried using two HS-5645MG in the base but wasn’t happy with the noise the two servos made when they were working against each other (this shouldn’t happen, but it did, and I couldn’t correct it). So I went with a single HSR-5990TG, which works but is not as smooth as I’d like.
So I now have ordered a HS-5745MG to replace the 5990 in the hopes that it will have a more solid base. Plus, come on, it’s undeniably cool to look at in the previous pictures Jim posted.
The larger servos have better heat dissipation than the smaller ones. They will do the work for longer before they heat up. The 5745 would be the best choice for the strongest base of an arm.
Okay, thanks Jim. We’ll see how it goes. Incidentally, here are a couple of pictures for where it’s being used. The servo on the left is not currently being used other than as an “idler.”
