e-E-Flite Blade CP mCX CX 400-3D > Confused about DD

Hi Everyone. I know that there are a lot of previous writings about the GWS DD enhancements, but I am still totaly lost. The Blade CP is my first attempt at R/C aircraft. Also, I have been learning to fly it now for about a month. I have can now hover for about 30 secs or so. Can you please set me straight on this DD subject? Oh by the way, I did do multiple searches on the DD subject. I only became more confused. I have also read just about every site I could find on helicopters and heli flight in an attempt to educate myself on the total picture. I will try to organize my questions and please forgive me if some of them are not as advanced as they should be.

First: Do the stock Blades have Direct Drive already?

Second: Would the only alternative to Direct Drive be something like a worm gear assembly driven by the main motor?

Third: I was forced to look into tail motor upgrades/repairs since my bushing fell out of the stock motor. I am now totally confused about the easiest/best tail motor upgrade since I need to repair it anyway. I purchased an EDP50XC motor and a GSW 2003 prop from the LHS. Some of their personnel mentioned flipping the prop backwards, wiring backwards, etc. I mounted it to the original Blade tail motor mount by grinding the flat side round (so the motor shaft points to the right like the stock motor). I know that the new GWS motor turns clockwise and I am not sure if this is correct for the design of the aircraft (I thought the original turned counter clockwise). Oh yea, the LHS said that they had better experience with the 2003 prop with the Blades that still ran stock batteries (it is a 3.25x3 prop), which is why I have installed it instead of the smaller props that the motor came with. If I reverse the leads to the motor, it does not hold the tail proper due to the design of the prop. Can someone explain the proper way to perform the GWS upgrade? I read all kinds of info on it from this forum, but there appeared to be just as many methods to perform it.

Fourth: Should I just use the original gear and prop with a green "loctite" 'ed pinion on the GWS motor (wired backwards) like I have read in another discussion?

Fifth: This new GWS motor seems to wear down my stock batteries much quicker (I have not upgraded to the li-po batteries yet). Does this sound normal? I realize it may use more electricity, but it may also be that it works harder to keep the tail stable.

Thank you so much for your assistance. This is a great forum full of great people.

>>First: Do the stock Blades have Direct Drive already?

Answer: No, there is a gear between the tail motor and the actual tail blade. Direct Drive means the motor goes straight to the blade.

>>Second: Would the only alternative to Direct Drive be something like a worm gear assembly driven by the main motor?

Answer: Well there is the stock way with a gear between the tail motor and tail blades, direct drive as explained above, gear assembly driven by the mail motor and belt drive by the main motor. I think that is all I have seen, the ones driven by the main motor would be quite difficult to upgrade to on the Blade though. You would probably be better off buying a new helicopter kit with that feature.

>>Third: Can someone explain the proper way to perform the GWS upgrade?

Answer: Not sure since I didn't go this route, I installed a ducted fan on mine.

>>Fourth: Should I just use the original gear and prop with a green "loctite" 'ed pinion on the GWS motor (wired backwards) like I have read in another discussion?

Answer: I think the point of the GWS motor was to go direct drive and eliminate the gear assembly. And also to extend the life of the motor obviously.

>>Fifth: This new GWS motor seems to wear down my stock batteries much quicker (I have not upgraded to the li-po batteries yet). Does this sound normal?

Answer: My guess is it will go through batteries a little faster since it's a stronger motor but I think you may have it hooked up wrong from your above questions.

Do not use the stock tail rotor prop with the direct drive GWS motor. It is way too large and will burn the motor out quickly. You want a 4.5 x 3 " prop or even a 4 x 2" prop. Some even use a 3 x 3 prop.

The best way to go direct drive tail is:

YOU NEED THESE THREE ITEMS - EVERYTHING YOU NEED IS HERE:

GW/HAS-002
GW/EDP-50/H
GW/H001-FD5002-030B

You can order it from: www.balsapr.com


Also read this - I already covered the pusher vs tractor options and how to wire the motor: http://runryder.com/helicopter/t201681p1/

Yes, you will put the prop on normally (edited). Yes the motor will be wired for reverse polarity. The motor will turn counter clockwise.

Here is a pic of the proper install of the GWS fin, motor, and 4530 (4.5 x 3") prop, with a cut down metal prop shaft adapter & rubber prop insert -everything that comes in those 3 items listed above:

Actually - I should say the GWS prop will go on normally - ie the writing on the prop wll be facing away from the motor...
