Thanks

OK, wasn't rocket science I know, but my very first tx mod is now successfully behind me and I can now buy servos without worrying about which way they turn .

Couldn't have done it on my own guys, thanks a lot for your advice.

After flying fixed wing for 22 years I know airfoils make a big difference in performance. A helicopter just uses a rotating wing so the principal should remain the same. I don't think you would want to fly a cp heli upside down without a symetrical blade. I'm getting better at sorting out speed versus nose down attitude, I just don't want all the excess speed. I see cp heli's fly in more wind and do it without flying balls to the wall, just looking for a happy medium and increased performance on this fixed pitch. But at the same time I know it will never fly quite like a cp heli. Have also considered modding the fly bar, either changing the weight or adding paddles. I will say that I have not suffered a fly bar strike yet and I have pulled full elevator from fff trying to get somewhat of a stall turn. Maybe the answer is just a much bigger heli with more mass, making it less wind sensitive.

The rain went off so I made the mistake of convincing myself the wind had dropped enough to let me try out the new servo... result below
CAUTION: do not watch without a sense of humour

windy flight... (3 min 49 sec)

Not the greatest vid in the world, but there are some pretty impressive 45 - 50° camera shots . If I keep it up I'll maybe get a flip out of it yet

Oh yeah, when it flew backward into the tree I had the elevator on full forward

This is really helpful. Thanks for all discussions and useful tips.
Now i have converted my F45 to BL-Mainmotor and i`m looking for a bigger Battery.
Did someone here use a 2800 MAh LiPo like this one?

I know that is another size but i think i can fit it with a little work on my F45.

I use 2200 mha batteries on my F45 and I think it is a bit too much for the brushed tail motor. If I stop flying at approx. 3.6 V the tail motor smell, not a good thing for sure.

Thanks for your answers!
I thought about the tail motor but hopefully it works.
Think i will try it and report

@ tigger

i try to fly too this day and it was a lot of wind.
With the BL it will work fine but it will be to fast for my skills
So i ended the session before i crash it.

I`m sorry for my bad English

Regards, Manfred

Yeah, was just saying to The Wife "when I get my brushless motor...". Just means I can have more spectacular crashes .

No need to apologise for your English mate, we ALL speak one language here... HELI!!!

Edit:
My wife is in a "Bastelforum" with people from all over Germany, and they organise a get together once or twice a year. We need to get something like that organised for "heli flying and beer drinking". Any takers?

I know Frank (R.C.Man) would be into it, Roland is in the Alsace so isn't too far away and would also be more than welcome. Mystman I think only flies micro helis, but maybe he could also be talked into getting something bigger.

If anybody else in the area would be interested in giving it a go, PM me and I'll get a list together. I'm only 50, so I don't have a problem with a sleeping bag on someone's floor

With BL it fells more comfortable to fly but the results of crashes are also "more comfortable"

LOL - Yeah, mine got stuck in a tree the other day and I did the same thing to "knock" it loose!

Isn't that an awful feeling when your going backwards and you have full forward! But at least no damage and your still flying!

too true, nowhere else to goooooooooo!!!

... and all I'll be flying til the weather improves is my V911s

The shape of the blade helps determine what kind of disc you are creating as does the stiffness of the blade, especially on a fixed pitch. A flat, rigid disc provides much more response the a softer diheidral disc.
Similar changes happen even in a CP heli with different blades. Use a wider blade, a heavier blade, a softer plastic blade, or a stiff carbon fiber blade all effect flight characteristics. The is especially noticeable on flybarless. On my V120, I have 5 different blades and they all product different flight characteristics. Same on a 250 I have 3 different blades.
Each blade shape products different lift patterns just a the wing on an airplane, only in forward flight, the thrust is higher on the rear of the disc than at the front, although it really happens 90 degrees sooner due to gyroscopic progression.

Blade shapes certainly effect flight characteristics, response and head speed. Quicker response and more head speed improve your ability to pitch into the wind. But they do not have any impact on the disk that's created, as far as air penetration. A wire wheel allows no more air to penetrate than a solid wheel, when both are spinning. That's simple physics, easy to verify.

Welkies to the BEST Forum about 'the best bang for your buck' copter, Manfred. I am not sure of them batteries, I suspect the gains you seek will be offset by the additional weight of them batteries ( i bet the 2800 weighs 150 grams)

What kind of camera do you use? I see you don't have to mount it upside down like I do.

BTW I use a little rolled up piece of paper - could use anything the right size I suppose - stuck between the front of the camera and the chassis to take my heli's nose out of the picture. Then again, when it's at the top it looks kinda cool. When I invert the video and the nose is at the bottom it just looks kinda like "WTFH???"

Cheers, and happy flying. We got wind & rain today so I reckon I'll be modding my tx.

Fin I use the 'built for the '45 C4002 camera'. It is VGA, so resolution is poor. I did the same thing, a bit of cable sheath to prop the camera's nose down. My new 'mod of the day' is a better camera mount using rubberbands as a 'shock-mounts' . Did You get the email?

Badd, I used a bicycle/pedrestrian safety flasher that had 5 LEDs in it. 2 were yellow and low intensity so i put red high intensitys in their place (after unsoldering them and putting them on the switch side). The flasher is built right on the 4.25" x 1/2" pcb. it worked perfectly.
The specifics of the flasher is:
Brand = Longxi
item # JZ-0029
The tail flasher is one them 'screw on tire valve' flashing LEDs, modded slightly.
Got in a couple flights last night... the red chasers DEFF improve orientation / direction of flight.

All this discussions of blades has me wondering: Is there a better main blade type to use than the OEM F45 blades? I do have the brushless mod well on the way, but will that change the "better" blade type?

I broke both the main blades on my F45 Saturday. I had just done the "shim" mod on the lead/lag pivots. Obviously, I made them a bit too tight. My factory spares are out of balance, so I will need to replace these soon as well.

looks good, i love how you 'coaxed' it outta the tree
btw was them grey whiskers on yur face
