hyvä perus nopari

[Marcomi]

itse kun en tiedä yhtään mitään nopareista, niin mikäs olis hyvä ja kohtuu hintanen perus nopari? moottori on integyn lathe 65t. tuskin kyllä tolla tiedolla mitään tekee? :D

[RunWild81]

Novakin Rooster vois olla kohtuu hyvä, ei ainakaan ole hinnalla pilattu. Näkyy olevan noin 70-80 dollaria tällä hetkellä

Tässä olisi eräs uutuus, joka hyväksyy niin harjalliset kuin harjattomatkin moottorit: http://holmeshobbies.com/product.php?pr ... t=0&page=1

Kyseinen moottori on varmastikin ihan hyvä vaihtoehto. Ajattelin tilailla tossa vähän keväämmällä pari black revolveria Hustleriin. Samalla vois ottaa yhden kappaleen tommosia. Varsinkin uudempi ja laajempi softa kiinnostaa. Kuinkahan paljon ampeereja toi kestää maksimissaan?

Jopas jopas. Toihan olis mun crawlereihin kuin tehty   ;D. Täytyy kyllä hankkia pari Castle Sidewinderiä.

Siinä olis holmesilta analyysiä

Pardon the magazine style intro, this was written as an article and not a forum post. Feel free to ask any questions about it, I have been testing them for a while.

As technology and manufacturing progress, hobby electronics become more affordable and complex. Castle Creations gives a taste of the future with the very affordable Sidewinder ESC. This little powerhouse is available alone, or as a motor/ESC combo. The Sidewinder has all of the features of the Mamba Max, including Lipo cutoff, brushless mode, brushed mode, and a variety of programming options. The footprint is also the same as the Mamba Max at 1.8x1.4”. Adjustable drag brake and regenerative braking are also built into the Sidewinder. This allows you to have controlled descents on steep and technical sections, or you can program zero drag for those go fast bashers. Programming can be accomplished via stick or PC interface with the Castle Link. If you are familiar with the Mamba max, you will find the programming almost identical.

The first test was to see how well the Sidewinder pushed my XX buggy around. I used a stock Castle Creations 4600 motor/ESC combo for this test. No programming changes were made from the factory settings. The power was provided by 7 matched GP 3700 cells, gearing was 20/76. I noticed right away that the startup has been significantly refined as compared to the Mamba Max. Startups were rock solid and immediate. Also, I could push the rig backwards and it would take off in forward locomotion as soon as I told it to. A third change is that the startup is in fact slower. If you want to putt around at 1mph, you can now do so. Certainly a large improvement over previous startup routines. Even with the mild 4600 motor, I could pull wheelies from a slow roll. Once the rig was moving it was very easy to keep the rig dialed into whatever speed range I wanted. I went to test the temperatures, but there wasn't enough heat to even worry about. Castle gives a spec sheet that states about 45mph with a 3 cell lipo and the 4600 motor. I trust that data enough to move on to the next stage.

The second test was in a Wheely King with a HK-2221 scorpion outrunner of 4400kv. It is a 9 slot motor, and slotted motors are notorious for giving the Castle startup trouble. This is my worst case scenario. I even made the gear mesh a bit tight and put on my super heavy MSD delrin beadlocks. The gearing was 25/90, and the battery was a 3 cell 4000mah PolyRC. With the Mamba Max, the startup was not consistent. Sometimes it would take off, and sometimes it would stutter a bit. With the Sidewinder it took off every single time with no flaw. The motor had enough power to make the rig wheelie at any speed, and was really too much for the rig to handle. With full throttle the soft Moabs turned into pizza cutters, I would guess about 30mph. The outside temp was 38f, and the ESC and motor never got over 120F. In hotter weather it might push the Sidewinder a bit hard, but lighter wheels and gearing would certainly help. The main point is that the Sidewinder has better startups. Good job Castle!

The final test was in the AX-10 Rock Crawler. I put a Crawlmaster Sport in with a 3s Vislero 2100 pack for power. The servos were powered via CC BEC, since a 3 cell lipo makes the Sidewinder's internal BEC near useless. The startup was smoother than a Mamba Max, with no surprises or hiccups. Neither the ESC or motor got warm at all during the test. The biggest improvement was startups while the rig rolls backwards or is under load. Every time I gave it throttle, the motor would start up predictably. The only problems were in very hard binds, when it would be better to pick the rig up instead of trying to throttle out. In these hard binds the motor would chirp and try, but I was too afraid to give more throttle for fear of breaking parts. All in all, it worked very well with an outrunner.

Next up was brushed mode. Unfortunately I could not get the ESC to hit the 9th step in programming, so I could not test this. I don't know if this is my problem or an oversight in the first release of firmware. Castle will be contacted.

Overall, the Sidewinder is a great controller for a great price. The positives are the startup, the cost, the overall power, and the plug and play aspect. The downside to the controller is that the Castle link has not been updated yet, so the controller cannot be USB programmed as of this writing. Also, the lack of brushed mode troubles me. I know it is supposed to have brushed mode- it is in fact in the manual. I would have liked to see Castle release the ESC and the Castle Link update at the same time. But, until that day it is still a great brushless ESC at a price point that no other company is near. My final conclusion- Castle made the right choice when they designed this ESC.

Hmm... Ikävä varjopuoli, kun puhe on kuitenkin ollut harjalliset ja harjattomat hyväksyvästä. Onhan tossa kuitenkin vielä mahdollisuus, että tulee esim. softapäivityksenä, kun kerran manuaalissakin on :).

[Osgard]

Luulis kyl tulevan ku ohjeissa lukee. Näitä saattaa tulla kaksi yhteen projektiin jos toteutuu projekti ja tulee se harjallisten tuki mukaan.

Ellen ihan väärin muista, luin että holmeshobbiesin nopareissa on uus softapäivitys jo vakiona.

Holmesin sivuilta poimittua

Programmable with the Castle Link accessory programmer, (pending the next update from Castle) Best of all, the software has been updated for even better control of brushless motors!

[RunWild81]

Mitäs eroa nyt Sidewinderilla ja Maxilla on näin käytännössä?

[Osgard]

Sidewinder kestää pikkasen vähemmän virtaa.

[RunWild81]

Sidewinder tuli tilattua, ihmetellään lisää kun saadaan se tänne asti. Holmesin mukaan CC on uudessä päivityksessään juuri korjannut tuon karvallisen tuen

[TomiK]

Sidewinderin pitäisi saapua ensi viikolla (piti jo tällä, mutta eipä ole näkynyt)... Sitten lisää testiä Crawlmasterin kera :).

[TomiK]

Eilen sain viimeinkin Sidewinderin ja Crawlmasterin tullista (PRKL!). Testit on vielä tekemättä, mutta ehkä tällä viikolla vielä jotain sisätestiä.

[RunWild81]

Hiukan ongelmia tuon säätämisessä, ei meinaa sitten millään tunnistaa kaasun neutral asentoa futaban radiossa

[RunWild81]

Ongelma mystisesti katosi, en tehnyt mitään muuta kun kävin kaupassa välillä. Löin laitteet päälle ja heti tunnisti kaiken... o_O
