Century scale mechanics J bolt
Anyone familiar with Century's scale mechanics? A have their 5bladed head which has a 4mm Jesus bolt while the main shaft has a 2.5mm hole. Just wondering if I got the wrong mainshaft or if I am supposed to drill out the hole as part of this "quality kit"

I would keep the rotorhead and sell the rest. Century customer support sucks. Buy the goblin mechanics or just use a Trex airframe. You will be more happy and you can get spare parts. I sold all of my Century helis and I will never again buy another helicopter from them. Even if it was free I would not take it.

I have just drilled the main shaft to accept the bigger bolt with no issues. after drilling the hole out to 4mm, I then go up one size with the bit and just flare the opening on each side of the main shaft hole.drive a rotary, fly a rotorcraft

Thanks guys, appreciate the info. I have a little sport hawk that I fly around. Granted they are not the best helicopters around but they are affordable and fly pretty well. Other than a Vario Notar this will be my first multiblade scaler. I have heard other complaints about century's support but have not experienced that myself.

century 4 blade head j bolt
Hello,
I called century about that and they said that that was impossible! I made bushings out of 5/32 tubing for the head and used the 3mm bolt so I didn't have redrill the shaft. My kit was also missing the 4 rods going to the head which they sent me and charged me for them again! I've been dealing with century for over 10 years and they've treated me well, until now. Don't understand it, spent a lot of money there! Love their helicopters!

I will have to check for the rods, dont remember seeing them. I do have to say their ball links are terrible, I usually throw those away and use my own.

I ran into this before, and was basically told I had to make it work myself.

Never had a heli shake so bad (didn't last long either).
E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.

I've done the 5/32 bushing method as well and that idea works well. Ken u should not have been charged for missing parts from your kit. I would call them to resolve that ( call, don't email)drive a rotary, fly a rotorcraft
