Castle 1717

Wowsers, Big diesel bastards they are ! Sweet.

I'm thinking it would be easiest to have the shaft turned down. It can be done at home if you're careful but I'm worried about getting the shaft too hot, gotta stop to let it cool often.

Whoa, just read that, 6mm shaft?

Now I couldn't use it even if I did have it....which I don't. No word on mine yet.

Shouldn't take to long for a 1 mm ?

Drill press might be a bit difficult, I was thinking of rigging up something to get the motor spinning at partial throttle and then using either some really good sand paper or maybe carefully use my Dremel to take off little bits at a time.

Just checked my credit card online and I was charged for my order today, so its is on the way, just didn't get an email....

There is a prob though - they charged me full price for the 1717 even though I ordered on 11/30. Guess I'll have to get that straightened out tomorrow on the phone.

Then it gets to sit while I fugure out what to do about finding 6mm pinions...

common bondo! we can do better than that!
i'd go with removing the rotor and finding some way to tail-stop it then machine with a carbide tip in the lathe.

Hmm, thats a bugger. I have a feeling CC will be getting a piece of my mind if the 1717 shows up with a 6mm shaft. How hard is it to proof read your website? Seems like we do it fairly frequently (check this thread for examples...). I will have to contact CC about sending me a modded shaft to replace the 6mm unit... Of they can send me about 50 mod 1 6mm bore pinion gears to replace my stock...

I had a kb45 turned down once, but it was not ground for a flat area yet. I had to make up a pvc collar as the machinist did not want to magnitize his lathe with the rotor magnet. A real PITA, spent about 1 hr at lowes getting the correct sizes of pvc rounded up. Then he had to turn it to fit the rotor to clamp it properly. A grinding stone and partial throttle should work, but I really do not want to do that to a 200 dollar motor.

I'm curious why they would put a 6mm shaft on it, they are basically building it for US and other future RC-M nut jobs and we all run 5mm shafts. If it has something to do with a helicopter needing a 6mm shaft or something, put that shaft on the Heli version with the ground down fins and give us the 5mm shaft! I'm not going to pitch a huge fit over it because I bought the motor before there was anything really known about it (said 5mm shaft on the chart, but it wasn't the only error) because I had faith in CC that they wouldn't do something so stupid as to give us the shaft like this.

No worries guys, It's not hobbysh1tty were dealing with. Maybe a misprint warranty that still covers a grinded shaft and/or a easy rotor swap out?

How about 8mm mod 1 pinions? + with Mikes 8mm-6mm adpt.?

Thats just beautiful...

45k rpm max is kind of a let down

I was curious what the RPM limit on these would be, I was expecting it would be 60,000 like the 15** motors since even their 2220 (or 2225, I don't remember) has a 45,000 limit. I don't plan to push it past 35,000 but it's always nice to know you have the headroom for safety or to push it faster if you so desired.

Got mine today. Thing is massive!



Century Heli has 6mm mod 1 pinions in 9-11 teeth. Apparently pretty common for heli applications?
