2. When I throttle up, everything is cutting off. If I cut the throttle and come backup it restarts again. Not sure if it's the ESC or something else. I have a good 950mah 11.1 volt battery, fully charged. Wired things up like showin the Blade manual.
I have this same problem but never figured it out. Seems to fly fine after that initial cutoff during the first throttle up. I'd be interested to hear what you find out though. Other than that, I really like my arc110.

Well,

I completed a complete head and shaft rebuild last night. Reprogrammed the CC10 Controller per the article in May RC Heli.

I will be putting the CF Blades on and fireing it up tonight. I'm sticking with the 9 tooth pinion. I'm hoping it was just the settings on the CC10 that caused the problem. I changed the timing to slow, and the voltage cutoff to soft (it was hard).

I put a GWS Direct drive tail on last night as well. Anxious to see how it performs.

FYI, those "Cold Soldering" units that run off 4 AA batteries are GREAT for working on these little helis. Radio Shack sells them for 19.99. I'm always dubious about things sold on late night TV, but this thing really works well.

The motor itself is not vibrating. Runs smooth. However, I noticed two things.

1. The basic plastic frame is very "springy" towards the front, not stiff at all. It's actually "designed" that way from looking at the way the frame is molded. This would seem to potentially cause the motor to change its mesh if there were vibrations.

2. The HDX300 motor seems to take a good blip on the throttle to get moving. It's very "notchy". It will sit there semi-stalled if you do not "spike it" to start. May be better with some mass, as this was off the heli. I would imagine this would just be an issue at startup, but it could be causing an initial spike in battery load. I would recommend what the guys do on the big REXES, and give the blades a spin, just before throttleing up.

I'll let you all know how it goes on the test flight tonight.

Thanks for your help.

Regards,
Lee

Well I flew the CCP tonight with the HDX300 motor.

The problem seems to be mostly related to a bad battery.

I installed a GWS EDP 50XC direct drive motor, but I haven't got something right. It will only turn one way, and I had to reverse the motor. I think I need to put the motor back, turn the prop around and reverse the Gyro. Smashed a brand new set of Symetrical woodies, but other then that seems to be OK.

This thing is cheesing me off. I think stock is the way it likes to be. Everything else is just an excersise in frustration! ARGHH!

I've got two HDX 300 motors, one in a CP Pro with the Freestyle hobby belt drive tail, and the other in a fiberglass frame HDX/Compy 300 hybrid (also a belt drive tail). The CP Pro is running a 9 tooth pinion and in the limited test flights I've done since the conversion seems OK as is.

The Mini-Rex hybrid is running the Sonix 18 amp ESC with a 10 tooth pinion, Heli-Direct V2 rotor head assembly, a scaled down version of a Trex head, and 255 mm carbon fibre blades. Headspeed seems about the same as my Trex 450 SE with stock Align motor and ESC, but the smaller 300 class heli is far more responsive. It's all being driven by a Thunder Power 1320 pack, plenty of power and flight time, and temps on all of the pieces is in the slightly warm range after a full flight.

I think the HDX 300 is a great motor for the price and is perfect for most 300 class helis.

I learned to fly on a Trex, I learned to crash on a Blade CP...

well I installed the motor, I need to go and get a jst connector for my esc along with some bullet connectors for the motor and then I should be set.

Can I see pics of where you guys mounted your esc and stuff. I have a tail esc and a main esc to mount.

can someone post some pics of how they routed the wires around the hdx300. I'm trying to mount them to the chassis, but when I zip tie around the chassis, the zip tie is just about touching the main gear, wonder if there is a better way.

I had run the HDX 300 with an 18A esc (virtuoso) and a 1250 mah lipo, flew very nice, lots o power

Then I came across a good deal on a Fieggao 4150kv brushless inrunner. It uses a 2mm shaft, so I ended up using a stock BCP 8t pinion (press on).

LOVED the Fieggao! Although not as powerful, this thing ran SUPER smooth and SUPER cool. I used that same set-up later on in an HDX300 heli, very nice.
