I recently bought a T-Rex 450 XL here on RunRyder that was supposed to be CCPM (CDE). I received it and it turns out to be the standard mixing (HDE). This is my first experience with a T-Rex. I want a CDE T-Rex. I did a bit of searching at different web-sites and came accross this "conversion kit" . Is this all I need to make my HDE 450 XL T-Rex a CDE? Do I need new frames also? Will it be exactly the same as if i had bought a CDE T-Rex to start with?

Hi Mr Green,
I think that there ist no advantage with this kit. it is better to do conversion to a ccpm 120° mixing with direct links. Only a direct link version will improve the flight feeling.

So this "conversion kit "does not make my HDE version the same as the CDE version?

Yes it does make your kit the CDE but what he is saying is that turning you rex from what you have to what you want to get isn't going to be any better than what you have now. He is saying if you want to make it fly better than you need to upgrade to the direct link setup to make it feel better when flying.

A direct link setup is where your servos connect directly to your swashplate from your links. Here is a picture

Like it has been mentioned before, converting a HDE to CDE does not necessarily make it fly better. Out of the box, they both fly well. However, if you want the full benefit of CCPM, then purchase the CF frame set instead. The direct CCPM arrangement really tightens up all the controls and make them fast and precise.

Mr Green,
The kit you are looking at will make your HDE exactly like the CDE along with all of its servo mounting/canopy rubbing problems. When you have spent your money and done the installation it will not fly differently and you will have wasted the effort. I have both a CDE and an HDE and they fly exactly the same. In fact the HDE seems to have less interaction on the cyclic controls. These small cheap servos we are forced to use are not very accurate and eCCPM demands accurate servos. I am assembling an SE and it will have all digital servos and perhaps it will fly better than my HDE.

I agree the HDE is the better choice. Alan Szabos still using mCCPM without a problem.

Digital servos, the JR's? I'm seriously considering these. I've also heard the 9650 Futaba's may fit with some help from the dremel but I wont know for sure till I get my hands on some. Futaba's backordered till January

The standed 450xl ccpm kit has bags more cyclic power than the direct linkage setup i know i fly both and the cde wins hands down against the direct linkage setup
I have not tried the hde trex so i don't know how it performs against the cde

The world is round you can run but you will always end up where you started from

are you riunning th smae servos on both? How would you explane more power from the same servo? Only way I can think is a better mechanical advantage. If that is the csae then you will be loosing speed. Do you notice any difference in the speed between the two?
