I have seen more than a few posts regarding the heat issue in the TDR. Some choose to pay extra money for a "cooler" running motor, some choose to not fly as hard.
From my experience, ANY electric heli has to be able to get the heat from the electronics and away from them. Most companies do that with holes in the canopies but the TDR does not offer that as an option as the canopy is very sleek, tight, and closed up.
The NACA duct is a veru nice way of getting the air movement going in the right direction, and I have one, but I am sure a simple hole in the nose of the canopy will suffice and here is why.
I am a Firefighter by trade and when we fight fires in structures, we use a combination of pressurized ventilation and water to extinguish the fire. What we have found it no matter how much water you ut on the fire, if the heat and gasses are not expelled from the domicile, the problem will just get worse. Remove the heat and gases, the fire goes out faster.
Apply that to the TDR......It does not matter how cool your motor runs, if the heat generated by flight is not moved away from the motor/ESC/servos (which are in very close proximity to the motor) the build up makes for a very hot canopy area. That build up will cause ESC shutdowns, motor bearing failures, and electronics failures.
Cutting a small hole in the nose of the canopy for the TDR will serve two purposes, getting cool air in, and pressurizing the electronics area so the heat has to move away from the area and out the rear of the canopy.
I noticed a 20 degree drop in electronics and motor temps as soon as the Naca Duct was installed. Made me feel a lot better about my setup.
Because the TDR's canopy is so tight, any amount of cool air introduced in the area will "pressurize" the canopy thus expelling the heat out of the area. That is why I believe the NACA Duct is not necessary to accomplish this.
If you have the Naca Duct, install it. If you don't, cut a small hole in the canopy and enjoy a cooler, happier setup...............Ron

There is a guy local to Dallas who is working on some sort of cutting edge "heat pipe" technology which he thinks he can apply to RC helicopters. But your hole in the front is an even simpler idea which seems to have had a dramatic effect. 20 degrees cooler is significant.

Nice post Ron,
What size hole in the nose? Aerodynamically, would the hole be better or the duct?

Still waiting for delivery of TDR.

You're most probably right about the duct, it should make little difference (if any) compared to a simple hole as far as motor cooling goes.
But a simple hole will create more drag and won't look as neat

With great power comes great voltage times great current !

When it blows by at over 150mph.... I don't think you'll see the hole.

The hole is ~1" long and 1/2" wide....shaped like the duct.
I am unsure about aerodynamics but I look at it this way....the heli is STUPID fast as it is and the only real time you are worrying about speed is in a speed run. If you are that concerned with aerodynamics then, use a normal canopy so you get maximum wind slickness
Just as an aside, I just got back from fling my helis. The TDR's electronics were very cool, the ESC was 85 degrees, servos 86 degrees, motor was 125 degrees. Well within range and the Logo which has a bigger hole and more open area for cooling, everything was 86 degrees....even the "hot running" Scorpion motor. The TDR flew for 6 minutes (12s 3700), and the Logo for 5 minutes (12s 3300)

I use liquid cooling on the headlight of my FPV ship. It use miniatures pumps and glycol circuit, everything is very light. The system shown here can dissipate 150W without breaking a sweat.



I been thinking about circulating liquid inside the motor mount to a tube coiled around the boom...

Ron,
We do not have a problem in the San Francisco Bay. We have natural cooling system.
My TDR is flying beautifully. I almost crashed, because I forgot to strap the batteries

@ Hugeone, did you make that system? what did you use for a pump? What is the total weight?
Thanks, Bill

Huge, that is cool....looks like the setup we used to water cool Precision Power car amplifiers back in the day...just smaller.
Quamberro, what kind of temps are you getting on your electronics there in SF???

I got my pumps from http://www.micropumps.co.uk
The pump weight 10g, I figure adding a cooling circuit to a TDR will be around 50g at most and an extra 120mA on the BEC circuit. The total weight of the light + two pumps, driver and two cooling circuits is under 200g. It produce over 16000 lumens or over 5 time the average car's pair of hi-beam.

I made everything from the current driver (0-14A) controllable from the TX to the parabolic reflector. A full build thread can be found here:

Ron.
Here is the answer to your question.
Speed control 105 degrees
Pyro Motor 120 degrees.
Tempeture in the bay area these days are 75-78 degrees.
I do not do crazy things with this heli.

something like this to get the heat out? I'm testing the prototypes now. It looks like a regular cooling fan, but it sounds like a little ducted fan on 12V, something like 23 cfm. The custom mount clamps onto a standard jive heatsink, so if you already have one epoxied on, your good to go. If i were to sell an item like this, would anyone be interested?

Vents...
I recently had a tdr canopy cut with some vents ...and it really helped to get the heat out... Plus it looks damn cool...theres pics in my gallery if you want to see what it looks like...
