CopterX CX450SE V2 Helicopter Kit

Question: Does CopterX Helicopter spare parts compatible to Align 450 spare parts?
In short, my personal experience has been excellent. Plug and play and the quality is just as good as the align unit.

I fly CopterX V2 tails on both my helis and they rock.when and if I ever trash my heads they will be replaced with Copterx as well.

i also have the copter x head and tail assembly on my trex 450 it rocks. so smooth. it came with ball link arms that go to the servo arm. i popped them off (lazy) stuck in the copter x and checked the screws for tight (all were very tight) and flew. very smooth.night and day to my sa head. i was worried as well if i shouldn't have spent money not knowing if quality was the same. but i'm impressed. i've got a new se coming with metal head and i'll compare and let you know if parts will swap around. should be here in a day or so.

I have brought the copterx spare parts at swanghobby.com , they are in Hong Kong and fairly cheap, most important, free shipping :)

where to buy APC or Master Airscrew Propeller?

where to buy APC or Master Airscrew Propeller?

i have found a site where have APC and Master Airscrew propelller

Sometime, you would face the following problem
The prop's internal diameter is less than that of collector's, Can i make prop's hole big? will it make any difference to its performance?Even after tightening the spinner fully collector isn't fixed with motor properly I am new to RC world and this is my first experience with these motors and props, Can you pls suggest what can be done?

Answer
You put the collet on, then the base wedge, and then the propeller and then the nut on the end. If the propeller shaft hole is too small, you use a special propeller reamer to enlarge the hole just enough to fit over the collet shaft.

I hope that it can help :)

RC Toy Propeller Selection

Propeller selection
Differences in propellers can drastically change flight characteristics, even if nothing else on the craft changes. Changes in pitch or length can adjust thrust but will also adjust the amount of strain on the powerplant. A prop with more blades creates more thrust if the prop turns at the same speed.
Some tips for propeller selection:
If a plane's cowl is low to the ground during takeoff or landing (short or no landing gear), a shorter prop with more blades can replace a longer prop and provide equal thrust.
The more air the prop moves, the more thrust is provided. A prop with a steeper pitch and/or wider blade will displace more air at the same speed. The more air displaced in each rotation, the more responsive the craft is in regard to its relative weight. 3D flyers require more air displacement in order to support the weight of the craft. A narrow prop with high pitch that may be used for racing can displace a lot of air at high RPMs but may not create enough displacement per rotation to be used for a higher drag bi-plane of the same wingspan.
If a prop is too long and/or too heavy, it can create a gyro effect which will counteract yaw and pitch and make the craft less responsive. A little gyro effect can be beneficial for stability, so this needs to be determined on a craft by craft basis.
