Do any of you know anything about these Titan upgrades?

It's made from G10 composite and CNC aluminium alloy parts

Good, bad, quality, etc.

Hard to tell from the pictures. Is it microheli?

I have some Microheli parts but they don't look like those. CNC maybe?

No, it's not microheli. It just say "Precision CNC Head System - Mini Titan E325" These are about a 1/3 cheaper than the mircoheli parts. With this hobby you usually get what you pay for, but then again some things are over priced.
That just made me wonder if it lacks quality.

They are made by Sonix and are available from Blinktrading and Flightbox in the UK'

The Sonix rotor head is a CNC copy of the plastic Titan rotor and is fully ballraced as well

I have this rotor head fitted to my Titan and it is a good quality unit and has very little 'slop' and greatly increases the stability of the heli.

The only issues I had from it were the size of the bolt heads on the mixing arms that would foul the flybar cradle, but a little filing down of the heads cure this.

It is a full metal rotor there is no G10, the only G10 upgrade is the body which is available from the above companies.

If it helps the unit does not look cheap even if it cost less than the Thunder Tiger upgrades.

Thanks for the info, simplyraptor. Do you know if the stock washout base is compatible with these? Neither Blinktrading nor Flightbox sell it separate.

I purchased the wash out base seperately from Blink Trading, I am surprised that they no longer list it!!!!

In which case buy the Thunder Tiger upgrade instead I have lust looked at Fusion Hobbies site and it looks identical.

Part number PV0808

I don't think the original will fit, but give it a try first before ordering the upgrade
