As the topic says: I had to put a new canopy on my MT after a crash. I don't like the appearance of the hole in the top of the canopy- is it necessary do you think for cooling?

Thanks.

Depends on what power system your using and how you fly. If you are 3Ding the stock motor and esc i say cut it out. Most of the upgraded systems run cooler so there really isn't any need for it. I'm not saying that one little vent will make the difference between running ok and burning up but it's always good to keep things cool if you can.

Hi RotorRage,

Thanks for the reply. I do have a stock motor with a Thunder Power esc. I have an axi cooler but haven't mounted it yet. I think you're right- probably better to err on the side of "cooler" than not.

I didnt cut mine out and when i finish a flight i can feel radiant heat around the top of the canopy. I say cut it out. Let the heat out.

CLB,

If you are running the stock motor and stock blades you HAVE TO cut the holes out. Not only those, but I'd highly recommend cutting additional air vents. The stock motor gets very hot. My stock ESC was going into thermal overload protection and pulsing the tail after only 6 minutes of hovering/basic flight indoors at a temp of only 70 degrees.

Now that I'm running Align wood blades, have MUCH MORE cut out of the canopy, cut some rubber heat shrink off the ESC and am flying more than hovering the overheating is basically gone.

Thanks everyone for the answers,

I did cut it out after all and of course the others. I fly with carbon fiber blades, stock motor and Thunder Power esc. Although I'm back to Align woodies after a blade crunching crash. In normal mode for flying circuits and working on orientation I get 7 mins and am putting less than 80% back in. I keep to 5 mins for idle up practicing and I'm still fine. Heat hasn't been an issue for me yet but it's been cool around here.

It's always good to stay cool but i have never had overheating problems with the align wood or any carbon blade. Even now i have no holes cut in the canopy. It really doesn't need them so i'v just been lazy about getting it done. I'll look for my gun tomorrow.

Rotor Rage,
What motor and esc are you running? Also what temps do you have on all 3? I just started running the align blades and my temps dropped a little 145 on the esc 125 on the battery and 150 on the motor. I noticed that i have increased my eun times by at least 2 minutes.

I'm running a JGF500th with the TT ESC and airthunder 2200mah batts. Even when i was using the stock motor it wasn't getting real hot. I would get temps for ya but i cant find my temp gun. I think with the stock motor and radix i was getting about 130* on the motor.

Toolman: I got some temps for you. Batt 116, Motor 107, ESC 140 *F in idle 1 100-85-100 This is with V-blades. The temps would be a little lower with radix or rotortechs ect. This was mesured after continuous stationary maneuvers and no holes in the conopy

Rotor rage,
Wow. Those are excellent temps. Ive been measuring mine and after many flights and testing my average was battery 120 stock esc 150 and stock motor 155. I also am starting out at 90 F though. It runs much better with the align blades. The temps are higher with the TT blades. I wish i could get mine down like yours. Oh well. I will probably upgrade the motor after a while. I think that is the key.

Although the JGF500th isn't the most powerful motor choice for the titan it runs pretty cool. You do have to run a larger pinion due to the lower KV though. I like the 14t. I have noticed recently that a more constant HS is more inportant TO ME than a high hs so i went down to 14t and started using throttle curves rather than 100% flat. I didn't like the way the cyclic feel would change when the head was loaded in some maneuvers.

RotorRage,

My tail belt has about 5mm of play. I was going to upgrade to the JGF450TH motor since it runs much cooler than the stock one but since I've started to do much more flight than hovering, it's really helped keep the temps down.

I looked at the JGF500TH and asked the developer himself and he said for basic flight at low headspeed (2100-2600) that the 450 would run cooler as it's designed to run slower and more efficient at lower headspeeds. By the time I need to buy it however, maybe I will be flying faster (faster headspeeds) and better off with the JGF500.

Since I'm holding off on changing the motor for now, I'm looking for my 2nd heli. I'm trying to decide between a Hurricane H550 XES PRO SE or Thunder Tiger E550 raptor.

Does anyone who has both care to comment on how they compare?

Thanks!

Dave
