Logo 690 speed control question

[Dennis Everett]

Will a Castle 160 with the fan fit in a Logo 690 ?

[EdinTexas]

Sorry I can't answer your question but it makes me wonder why you would want to put a 160 with a fan in a 690. Are you running a 6S setup? It's unlikely a 12S would draw anywhere close to that much amperage even under hard 3D.

[Dennis Everett]

it gets pretty warm , havnt put a temp gun on it yet , lol , main reason a guy has the 160 on a 600 and asked it I wanted to trade ...

[Fauropitotto]

Guy at my club is running an 80 on his. It's barely getting warm.

What are the logs showing in terms of amps and temperature?

I routinely draw 6500W+ on my 690. Depends how you fly, headspeed, etc.

6500W / 44.4V ~= 146A (which is about what my peak amps typically show.)

I don't have a Castle 160 to check it, but I think you could make one fit. YGE 160 HV w/ heatsink is what I'm currently running.

I am running a stock motor in my 690 with a yge160hv esc. I originally had the yge heatsink on it, but replaced that with just an .032 thick plate of aluminum that was much lighter and barely gets warm. I routinely hit peaks of 5500W/130A during my flights.(2020 rpm)

Had a Scorpion commander 120 in mine and kept getting thermal and over-amperage shut downs. One day it caught on fire. Replaced with a heatsinked YGE 160 and the problem is gone. Logged 60+ flights since then with 0 incidents.

[Ph@cops]

Oh, and I placed a small fan on top of the heatsink and it fits just fine under the stock canopy

It does fit, but it is a really tight one. My stock canopy with no modifications just touches the upper aft edge . I have thought about cutting clearance margins around the factory cutout, but have put it off. I have been trying to decide whether to exchange it out for a non fan version, but thus far haven't seen any issues with the canopy touching.

[Dennis Everett]

thanks guys , I cut a cooling "scoup" in the bottom of the canopy , seems to help ,so im gonna stick with the 120 for now , also cut a hole in the bottom tray to get more air into bec that's mounted there ...

I am going with a 690sx.

I was originally thinking yge 160. But maybe something lighter

What castle do you like ? Or. Other brand ?

The talon 120 looks pretty heavy ???

[mahbouni]

After a hard flight with my L600 with 640mm mains, I'm seeing peaks of over 160A in my Jive Pro 120HV logs. The FET temperature isn't bad, mid 60's centigrade if I remember correctly. I reckon I could easily pop 200A with 690mm blades. I'm even wondering if a Jive Pro 120HV will be sufficient when I get my 690SX.

[larryfl]

Maybe I should go with the yge 160 and put a bec in

I was trying to save some weight but maybe better off giving up 1-2 ounces extra

I tried to fit both Castle Edge 160 with and without fan

With Fan: I could not get this to fit under the canopy.

Without Fan: Fits nicely under canopy

On Ron's advice, I just swapped out my 160 with fan to a 120. I have not had a chance to fly it yet, but the max amps I pulled with the 160/5000mah packs and Edge 690/Switch 690 blades was 126. My highest temp logged with the fan was 94.

I'll post the difference in temps that I record when I get to fly it. One thing I noticed the last time I flew it was that it is noticeably lighter when I pick up my Trex 700 V3 in one hand and the 690 in the other. It ain't cause one arm is weaker than the other, either.
