Dragon Technology gearbox conversion
« on: 11, February, 2010 - 16:43:31 »
For those that didn't make in to "C5-25", there was a working protoype of electricDave's metal gearbox conversion on display;







The first prototype was displayed at Brooklands and will stay in its display case for a while longer yet .

Yesterday I collected the second one and will be fitting it to Voodoo next week in preparation for some serious testing over this years meetings etc  8).

We want to make sure it is properly sorted and reliable before making it available to everyone else... but we are getting closer to making a usable "maxxed out" 24v c5 a reality. :)

me too,

Q) now i have 2 x C5's - any discount for quantity? :D

 ;D


just a 'under development' thought here, the original large dog on the axle is nylon, these will have been fatigued with age, not sure how available they are so is it worth using/offering a chain drive conversion inplace of the belt?

This may be a good point to think about,as one of my drive cogs did crack?

Some more detail on the project, although we're not going to release all the exact details of this conversion since we're the ones who have paid for the "research and development" side and don't want to give away our hard won info for free  ;).

The idea behind the conversion was always to keep the "plug and play" fitment process as simple as possible. I wanted it so that no permanent alterations to the c5 were necessary, and nothing more than a spanner or screwdriver are needed to fit the kit - which is what we have. This means it was essential to retain and use the armature in its original unaltered state.

Provided the original drive cog fitted to your armature is in a good condition to begin with, this kit will not damage it. I will even go as far as to say that the original setup is more likely to damage the cog than this conversion kit  8).

We've spent a lot of time and money on this and believe thorough testing will prove we've got it right  8)

Another plus side of this conversion is that it will also accept motors that have had their small set of twin bearings snapped off the end of the armature - giving a new lease of life to those damaged components.

As for the large white drive cog fitted to the axle, it may well prove to be a weak link. But bear in mind these cases of fractures and fatigue have only started to surface after many years.

All the failures in maxxed out 24v c5's so far have been the gearboxes - the large axle drive cogs have coped well.
A replacement from Adam might be the cheap and simple answer if you're worried, and I think is preferable to going the chain drive route..

Exciting times  ;D

there might already replacement for the cog, i.e. on my V4 2.3 cortina engine, it had kind of fiber sprocket on the cam shaft and timing gear.

the amount of washing machine and acr engine designs out there as example, just got to be something close that would fit if they do eventually 'dry up' in supply.

after seeing the demo unit, like everyone else i'd bet, i'm dead keen to see it in voodoo and working, then in behemoth   ;D

I think your going down the correct path Karl, the K.I.S.S method is always the best way.

Keep It Simple Stupid - always works !

I gotta get me one of these - let me know when I can !

We have waited 25 years for it....but we are wanting it very soon !!!!!

 Good luck with the testing and thanks for the time and effort in the development. Keep us informed on the testing front
