I'm looking at the mods that people suggest for the CPP (DD tail, brushless main, HH gyro)

The parts for the DD tail are pretty straight forward (oer the bladecpprepair.com) even though noone has the motor in stock :roll:

My question, is which BL motor to use for the main? Is the Park 370 Brushless Motor 4100kV (http://secure.hobbyzone.com/catalog/HZ/eflite_cppro/eflite_badepro_optional/EFLM1000.html) a good one? And is the eflite 20-amp Brushless ESC (http://secure.hobbyzone.com/catalog/HZ/eflite_cppro/eflite_badepro_optional/EFLA311B.html) a good one for this?

And if I'm gonna go through this trouble, which HH gyro would you guys suggest - just a futaba 401? (seems kinda expensive for this "toy"/practice chopper) I know that someone is using the G90...

Without the HH gyro, looks like it's only ~$120 in mods... so pretty low price...[/url]

I use the E-Flite Park 400 4200kV motor with a Castle Phoenix 10 ESC. I'm also using the G90 gyro on dual motor tail. I wouldn't put a 401 on it, I just think the weight would be too much. The G90 works fine for the Blade.

I run an E-Flite Park 370, 3600KV w/9T pinion on 3S LiPo w/DD tail.. Plenty of power and head speed is right around 2100 RPM.

Hacker 3700kv, 9 tooth pinion, Castle Creations Phoenix 10 ESC. 2230 RPM here. Works well, I think the E-Flites are about the same.

Hdx 300, 3800KV outrunner, 9 tooth pinion performs well and I like: Price, cool running, size and wiring exit at the base. Works especially well for enclosed scale body situations where air flow is restricted. Also have an E-Flite Park 370 that works very well and is my choice for pod and boom set-ups that have adequate airflow. It is an expensive motor compared to the HDX 300 outrunner but I like the inrunner design where you don't have to contend with a can whirling around on the outside. Don't like: Wire exit location. Makes it a more gangly ESC hook-up and long high power wires on a micro can lead to some RFI problems. Then, ESC of your choice @ 10 to 18A. FWIW
