3D Weird Blade 400 / MD 500 Issue
Hi Guys
I have a Stock Blade 400 that I stuffed into a MD 500 Fuse
while I was Hover Testing it for about 4 Minutes, The Heli Lost Power and Dropped Like a stone, from 4 ft off the ground
I have been Flying this Helicopter for Two Years with no Prior issues up till now
when I was assembling the Heli into the Fuse, I Put a New Stock Motor on the Frame, so I could try to avoid an Issue with the Motor asking it to Carry a Heavier Load
I also Put a New 2200mHr. Lipo into the Project also, to Make sure it would sustain the Heavier Helicopter, for a 5 Minute Flight
I checked the Battery and it Has 3.8 / 3.8 / 3.81 Volts Left in it, and was only Slightly Warm to the touch
I also felt the Motor, which was also Slightly warm to the Touch
do you guys think I should up grade the Motor & Esc ???
do you have any suggestions ???
I remember that Horizon Had Issues with the DX6i Pot's in the Past, and recalled them
I sent mine in, and they Supposedly fixed it,I haven't used this Radio Much since then, I Had the Same thing Happen in the Past with another Heli, a Mini Titan w/ an Agusta 109 A Fuse, and this was why I sent it in for the Recall,this One Lost Power, and Dropped from 4 ft up to the Ground too
Now it's got me Wondering if it's still the Transmitter

Is it the stock ESC? These ESC's are not good. Did you check the temp of the esc? Also where is it in the fuse? If it can't get airflow it will also overheat. I blew one up doing normal flying with just a few flips to inverted. Nothing hard at all. With the increase in weight you will require more power. This might have been too much for the ESC and it shut down. Can you power the heli? When i blew mine you couldn't turn the blades with the motor even with a fresh battery.Stratus 90, Synergy E6, Trex 450 Pro

I didn't feel the ESC
Hi thanks for the Reply
I didn't Check the Temp on it WHEN IT HAPPENED(DAM)
I just went and spun it up and it's still Working
it is in the Stock Position though Below the Battery Tray
Bad thing for me is I have Put a Switch on the Bottom of the Helicopter to Activate the Power, so I don't have to Pull the Front Canopy to turn it on, so I'll Have to do some Rewiring
what do you Recommend for a New / Better Replacement ESC
I will Have to Find another Location to Mount it too I guess, so it'll get some Air Flow
the MD has all the Windows installed so it's Pretty enclosed

Well I think I found Part of the Answer
I Now Know I need an Align 35 Amp ESC But also
I found some CPU Cooling Fans I had down Stairs
they Run on 12 Volt and it's small enough and Very Light so it'll fit right on the Side of the Frame inside the Fuse blowing across the ESC's Heat sink
I will Have to Take out the Two side Windows so it Can Have as Much Air as possible
Here's the Dimensions of the Fan's

2.36" x 2.36" (60mm) Just Cooler Sleeve Bearing Case Fan w/3-Pin
Connector (Black) 6010-BULK-NP
these Fans from http://www.geeks.co are a Whole $1.50 too

# General Features:
# 2.36 x 2.36-inch (60 mm) Fan
# DC 12V
# 19 CFM
# 4800 RPM
# 37 dBA
# Sleeve bearing
# Brushless
# 3-pin power connector

i too have a blade 400 and MD500 scale fuse - i bought a castle HV-45 (probably overkill, but won't hurt) and an align 430xl motor. it'll give the extra 'umph' the heavier bird will need. (i have the new align motor up for sale, btw)
