Hello,

As I see EMCycle received an answer, so I dare to ask help for me too

I own 9116. I am new to any kind of RC.

I want to modify my 9116 so it could fly more than 10 minutes, but actually cannot think of anything possible. At first I thought to plug bigger battery. My friend has same kind of 9116 and he got replacement battery from somewhere I don't know with higher mAh. he gained literally 75 seconds! on the other hand, after the flight his heli is way hotter than mine.
So i thought maybe it is worth to modify more than replace a battery, so I found a web site that trades motors for helis. they trade brushless motors 2200-3000kv for around $15 and I think it is cheap. if i mount this motor to my 9116, i can plug bigger battery (as I know brushless motors do not overheat as easy as usual ones) and gain some more operating time.

how do you think, will this work?

PS. this is my first post on this forum, so if i posted wrongly - i am really sorry.
PSS If I am asking something really stupid, be kind to tell me

A larger battery or brushless conversion would expose a lot of potential problems with the DH9116. It's a toy grade product that isn't designed with much excess capacity in any area.

Here are things you need to consider:

The heli is overweight and motors are marginal. Increasing weight with heavier batteries will only damage the main motor sooner. There aren't any good upgrades, either. They only make these tin can motors in fixed sizes and the 180 is the only size that fits.

A brushless upgrade requires a motor, ESC, signal converter and some very careful soldering on the PCB. The PCB already has marginal quality soldering and undersized wires. The cost would be about $60.

The shape of the stock blades has lots of drag, meaning you would need to find blades that fit the performance curve of a brushless motor or it will draw excess amperage and toast your PCB.

Assuming you overcome these issues, you will have a main motor that's too powerful for the tail motor, which is very weak to begin with and only lasts a few hours. You will have to upgrade the tail motor, putting more load on a weak PCB.

Assuming you overcome that problem, the heli will have more power than the weak head design and servos can handle.

The best thing you can do with this heli is to upgrade the wiring. Not an easy task, but it does aid performance and provide more efficient current flow.

Bair14,

Which wiring are you referring to in your statement about upgrading? Just the main motor wiring like Steve did or are you also talking about the tail-motor and/or battery to pcb wires?

from what you wrote only conclusion of mine, is that I should leave this thing as is and look for a better option.

Can you recommend any electric helicopter that can fly at least 15 minutes with one charge?

I can spend about $150 on it, not more...

I was mainly referring to what Steve has done. The tail motor assembly really needs replacing with a direct drive unit. At that time I would look at the wiring. I didn't think the battery wires were bad, though upgrading to better C rating might mean bigger gauge wires and better connectors. I would ask Steve about that.

Other than replacing failed parts, there isn't a lot to be gained by upgrading this heli. Use it as is, learn what you can from it and move on.

Flying for 15 minutes per charge is unrealistic with any heli. You would be carrying more weight than you should. It will impact performance and make your motors run hotter. But, most of all, it's hard to maintain the level of concentration needed for that long. It's far better to fly for 7 or 8 minutes, swap batteries, wait a minute or two and go again. You can repeat that cycle for hours. I have quads that will fly for 15 minutes, but that's a different kind of flying. I can turn on several flight assist modes when I want to take break from concentrating hard.

15 minutes is a long time to fly. 10 minutes is long time to fly a heli/ quad maybe. Most 4 ch/ 6ch six minutes is decent flight time. Quads 6-8 minutes is good.
Heat is main problem as these motors have no fluid going through them or any coolant. Bigger batteries/ motors etc will affect pcb but you will find out. 9116/ f-45 are entry level cheap helis. Yes they fly. Rotating helis can give you hours of flying. Fly one let one cool off/ extra batteries/ cool down time you are good to go. Have fun
