Ok so let's rule out a couple of parts that have been replaced

Ball links
Main motor
Main shaft
Rear rotor

My heli struggles to get off the ground when I have the training gear on it seems. However with it off it seems to be alot easier to get off the ground. Aside from the above parts any other things I should check? I re-aligned my blade pitch it's now at 1-2 deg positive. in idle up mode with all trims centered.

I'm running the plastic blades (which I'm suspecting are too heavy)

If anyone of you have experienced such a problem with lack of power for take off please share.

How old are the motors?

If you are using the training gear, Do not use the idle up mode. Increase your blade pitch one turn at a time until you can lift off at about 3/4 throttle.

plastic blades are probably too heavy if your not using lipo. Also are you at altitude? It is harder to get lift at altitude. I suggest going to lipo and getting rid of the plastics for now.

Motors are 2 days old (replacements were put in because I suspected bad motors).

maybe the whole setup is too heavy with plastic blades, worst case I guess I could just throw on the CF ones but I'm still hesitant being still a trainer pilot.

For training the wood flat bottom blades are better because of the weight. Keep it in normal mode, put your throttle trim to just under half way up. Pitch should be about 3-5 degrees positive with throttle in full down. Heli should lift off at about 60 percent throttle. If this doesn't happen, I might recommend upgrading your battery to a TP1320.

actually today while taking it up with a friends he was also having troubles getting power from his glider motor. Could it just be that we're in canada and NiMH batteries can't take the near zero soon to be sub zero temps?

this would explain why both my heli and his glider were unable to get any altitude dispite being different systems.

I have a Blade CP and have some input on this matter. I have found this heli to be greatly affected by the temperature outside. During an attempt to fly in 5 degree C conditions, the heli would lose head speed within 20 seconds and become unflyable. I have lots of experience flying electric planes in cold weather (all winter long) and know in this case it is not a result of the lipo battery getting cold. I think its possibly an issue with the 4 in 1 being used in a cold environment.

This is interresting quick question are NiMH affected more or less by the cold cause that's what I'm currently flying with. Don't have the cash for a decent charger yet and flight season is pretty much over (due to cold) so I'm still on the NiMH packs.
