Gemma Jane Posted August 16, 2008 Share Posted August 16, 2008 Hi guys, Have fitted the 'blue' parts to my CX-2 i.e. top bearing holder, heat sink, swashplate set, lower rotor hub.It seems the heli has lost it's 'zing' it takes more throttle to get off the ground, seems much more docile (i.e. less fun) and flight times have been reduced. It all seems to point to some sort of current drain that wasn't there before.Everything seems OK with the fitting, spindles move freely etc though if needs be I will swap out the new parts for old to find what is happening, just wondered if anyone else has experienced the same??

Simon Robinson Posted August 17, 2008 Share Posted August 17, 2008 I can only think of one thing, with adding the metal alloy parts will make the helicopter a little heavier and it will need more power to gain lift. Not sure what else it could be.? Sorry. Quote Link to comment Share on other sites More sharing options...
Kevin Davies 2 Posted August 17, 2008 Share Posted August 17, 2008 hi Gemma ive done the same as you plus extreme sport kit the heli is not as responsie i think its due to extra weight. i have one with extreme 180 motors which is quicker with the standard parts. i think this is such a good heli as standard the only worthwhile mod is the extended inner shaft to cut down on blade clashes. im going to weigh the 2 today to see the difference in the 2 weights.

Simon Robinson Posted August 17, 2008 Share Posted August 17, 2008 That will be intresting to find out the differance between the too helis. Quote Link to comment Share on other sites More sharing options...
Kevin Davies 2 Posted August 17, 2008 Share Posted August 17, 2008 hello again guys amazingly they both weigh 6 and half ounces so dont know whats going on here. although i have taken the fake tail rotor housing, and rotor and tail fin off so thats probably about 3 ounces. so the extreme one is about 9 ounces wouldnt have thought it would make such a difference.

Gemma Jane Posted August 17, 2008 Author Share Posted August 17, 2008 Thanks for the help. I've a feeling now that it might be that the alluminium swash plate has added friction to the set-up, or possibly that the servos are under some sort of greater load since I fitted the new swash plate. I've tried some oil to try and reduce friction which hasn't helped. I'll swap it out and report back. I first thought weight, but I'm fairly sure that the rotors are not spinning as fast for the same throttle movement as the stock set-up, advancing the throttle trim gets me closer to the original performance, but flight times are heavily reduced.

Kevin Davies 2 Posted August 17, 2008 Share Posted August 17, 2008 hi again Gemma ive done back to back tests on both my Cx2s now the standard one is quicker to climb than the modded one but the modded one is less prone to the wind so i think ive gained on one and lost on the other.. swings and roundabouts. the extreme 180s are giving longer flight times, getting a good 10 mins. out of my batts.

Gemma Jane Posted August 17, 2008 Author Share Posted August 17, 2008 Ta kevin, maybe I should go for a motor and battery upgrade then, must admit it does seem much more stable with the new parts, just that climb performance and flight time that is lacking. Guess it is always compromises depending on what we want to achieve. Quote Link to comment Share on other sites More sharing options...

Gemma Jane Posted August 17, 2008 Author Share Posted August 17, 2008 Could be Eric, flown it a couple of more times, now I'm accepting the climb performance loss, it is rather nice. I fly in quite a small room so I do not really need blistering climb performance, the ceiling isn't far from the ground! With the new parts I'm sure it is more stable, I seem to be able to get it in better trim and spot landings etc have improved. Be nice to get just that little bit of performance back though so I shall investigate Quote Link to comment Share on other sites More sharing options...
Gemma Jane Posted August 18, 2008 Author Share Posted August 18, 2008 Think you had it right Eric, bit of fiddling around with the linkages to the lower blades and checking everything was dead square, throttle performance is much improved. Not quite back to what it was but going by Kevins back to back test that is to be expected. Now very happy with it though, for me the blue parts upgrade was worthing it and I can really chuck the blade about the spare room now Quote Link to comment Share on other sites More sharing options...
Owen Hailey Posted August 27, 2008 Share Posted August 27, 2008 Hi Gemma.I fitted the up grades to my Robins 22 and had the same thing, It is dew to the little link on the top blades, as this has to be made longer by a turn or two to give them more pitch and the power will be back to normal.good luck Owen.

Gordon Low Posted February 13, 2009 Share Posted February 13, 2009 Hi Gemma Yes, I have experienced the same problem. If you are using the charger that came with the CX2, I would suggest buying a proper charger system. I bought the Ripmax, sigma EQ. This gives a good charge and balances the cells. Safe flying Gordon Quote Link to comment Share on other sites More sharing options...
joshua jones Posted February 14, 2009 Share Posted February 14, 2009 Hello, Gemma I think between you all youv'e pretty much sorted what the problems are i dont really have anything different to add but would just agree with what has allready been said. Sometime you know i do things expecting it to be better and sadly its not, Unfortunately i think we some time want to much and if im really honest i think the manufacturers know this which is why they sell "upgrades" after all they want to make money after you by the initial Heli. Im not been so sinicall that this is the only motive but i do suspect it is part of the "deal". And lets face it there is a argument that although you feel you have lost you have also gained so they have upgraded just not how you expected if that makes sense. My view on it is that the new alloy parts are as suspected producing more friction as metal to metal is surprisingly abrasive, this in turn is adding load to your servos making response more slugish but the whole lot is been held a lot tighter and in smaller tollerance giving less "flex" again feeling slugish on the sticks but also more stable as you have discovered. If it was me i would keep the new parts and as you rightly suggest upgrade the motor esc and gear chain but also change out the servos ffor something more manly. All the best happy hovering.
