Ive been running the square titanium drive shafts for a bout a month and they are great .

I tried TC3 composite ones they are good and cheap but the pin still rips through quite easy and the aluminium one have been re-drilled that many times they look like a culinder because at £10 each they are tooooooooo exspensive to keep replacing.

Since I have run the square titanium ones no problems.

I have yet to run them. Won't be able to run till the beginning of the new year. The tracks around here are closed for the holidays.

Don't use them unless you hit nothing and enjoy taking your front diff case apart to replace the Delrin outdrives....It's a nice design but susceptible to damage. The HPI one is ace.

Hi Frank,

How is the wear on aluminum HPI Spool? Does anyone make a steel unit?

Frank McKinney

I've only used it for one race meeting, about 5 runs and no noticeable wear so far. The thing is so light (it's hollow btw) that you won't want to try a steel spool I'm sure! The weight difference between the actual spool and an epoxied one-way is unbelievable. No one that I know of makes a steel version.

What the hell are you doing up so late anyway? Early start to the racing?

Yes i totally agree. I got one about a month ago and I have broken 3 outdrives. The things don't just break, they crumble.

I've used the aluminium spool, and it was really nice. I noticed very little wear (I used grease in the outdrives). The aluminium spool is sooooo light. It even out accelerated the one-way, due to the less rotating mass.

Has anyone broken any gears with the spool? I'm thinking of getting one but I don't want to sacrifice reliability...

I wonder how long it'll be before HPI release a spool backing plate just like they did with the one-way?

Frank McKinney

The way the gear attaches to the spool is the reverse of the way the gear attaches to the one-way, so the spool itself acts as the backing plate. You don't need to aluminium circular bit that comes with the 1.1 gears. The gear also attaches with 4 screws instead of 3.

I've run several packs at Don Valley (not sure if you've been there Skill) for the Mirage British Indoor Winter Series with the alum. spool and haven't broken any gears.
