Could you do another short video.
Unplug the main motor. Just slowly idled up to about 10% throttle. The slowly puts rudder all the way to the left and then all the way to the right.
Then do the same with the main motor running. I am curious what happens when main motor is under very little load.

Wow thank's, i am a clown, dont see this rod go out when i put a shim for blade. Now linkage are ok. Just many many time to get a right setting for ajust the servo connecting rod due to my bad manipulation on rear servo and found a good setting off % on remote control and learn to fly. Sorry to bother you

F45 Canopy mod and tab fix


Just thought I'd show a couple canopy mods you might find helpful. Until my buddy finds time to cut my too-fat heat sink down with his band saw, I cut an air scoop in the canopy. Seems to help a bit in keeping the motor cool. I'll do a nicer job of it on my replacement canopy!

The second pic shows how I used a staple to fix the tab at the bottom that started breaking from the very first 'hard landing'. Nice and snug again!

Ding Ding - We have a winner! Feathering shaft.

Good eyes.

Tuff boid testimonial


A gust of wind carried mine out of range and it dropped 100 feet onto a busy street. Luckily, it was in the parking lane! Came down skids first. Just sayin' that, as twisted and crunched as this thing was, I took it apart, hammered out the metal, and it's flying again with, seemingly, no problems!

One question for youz guys - Should the prop shaft be perfectly perpendicular to the ground? Mine is cocked a little to the left. I'm assuming the gyro is compensating because it flies OK. Or maybe that's the way it should be?

Fourth time out with the heli. First time out with C4002 cam. Ten minutes before the aforementioned crash.

It's very strange, but it never did that with my stock motor. I don't know why the tail is spinning with this motor, but it is and it's not pushing enough power to the blades to even get it off the ground.
If you are talking clockwise from above this is because the main motor is too weak. The tail is too strong and pushes the Heli in circles. If the motor is an 11v motor then this is an expected symptom. At 7.4v the motor will be under powered.

You weren't a bother at all. I'm glad I was able to help. I'm a new owner of this heli as well and have been getting help on here with mine, so I'm just glad that I was able to contribute.

I actually just figured that out myself. I had the main motor disconnected, so I plugged in that battery and gave some throttle. I noticed the tail moves clockwise to compensate for the main motor spin. The only thing I could figure is that with the main motor connected, it's too underpowered to handle the natural compensation from the tail.

I ordered a stock motor from China, but didn't want to wait that long, so I just ordered another heli from the U.S.. At least I'll be able to fly next week and I'll have a crap load of spare parts then.

Yea, trying to explain rotation is hard, especially when you're using different view points for comparison.

Not a bad thing to have 2 helis! When the spare motor comes you could put it into your first one and fly them back to back! Should be able to use the same TX for both heli's too.

That's the idea! I'll have to stick with my Align 100X until I get a flyable F45 next week. I've also got an Align 450SA, but I'm not good enough to do much with that thing. Man it's sensitive! I'm basically using the F45 to help me get ready for the 450.

I am confused.
When you spin up the main blades, the reaction should cause the heli to spin counter clockwise, which yours does. The tail rotor should trust to the right stopping this counter clockwise motion and maintain heading but pushing the tail to the left.
In your case, the heli seems to spin faster counter clockwise as the main rotor speed increases.
It would seem to me that the main motor is overpowering the tail rotor, which is not likely. I had a brushless motor that was way to powerful and fast and it would only just barely do that under full power.

I tried a HBFP V2 motor, which is 11.1V, in my F45 and it did that exact same thing, spinning ccw, and no lift.

Now if you could find a HBFP V1 motor, I believe those were 7.4V.

Do you think the 11.1 volt motors could be drawing so many amps that there is no power left for the tail. I can't see it being to powerful as it would have no where near the power the first brushless I tried.

I am totally guessing here, but maybe the gyro is setting the tail motor speed based on the main motor's power draw, which is not enough to get the 11.1V motor spinning fast enough.

I know with my little Solo Pro, as the voltage drops to near lvc, the heli starts to slowly rotate ccw - this is my cue to land.
