Default servo arm Q.

Well I thought I had my pitch just right(not) after I spun her up I re-checked my pitch...Guess what...I disconnected the motor and checked the pitch in idol up mode and I had almost no neg-pitch. I checked all my connector rod with a mic. and made them all even, but as I slid the swashplate upward to see where zero pitch would be(aprox) and saw that my rod needed to come up higher than they should.
So what I did was to remove the elbow connecter from the servo and place it at a 90 dagree angle( so that the arm was paralell th the flybar) this seems to give me the right pitch in both modes but is this a correct angle for these things?(the elbos) they wern't that way from walkera.
I've not seen any-thing that states which is proper.


Thanks in Advance...

dannoh... do you still have you DF40? what you are asking is the DF40 Servo horn right?
well walkera seemed to set-up the heli in an akward way.. but there set-up works since youhave to consider also the CG of the heli.. I have posted all that i did on my DF40 on tee.homanga.com, even some tips on the adustment made on the pitch angle of the blades and mechanical adjustments on the head...

The Pitch angle i have now on my DF40 is

-1° : 0% throttle
3° : 50% throttle
9° : Full

for 3D mode I have set it to

-9° : 0% throttle
0° : 50%
9° : 100%

but you have to set the mechanicals to center.. another thing is to make sure the swashplate is at the center of
the shaft so travel will be equal.. this is were you will be adjusting the ball links to set the swash at 90° if you made it correct then you wil have a balanced heli.. but you will be needing to test it at flight so you will be adjusting the correct weight distribution..

I have made alot af adjustment on my DF40 before I got it stable to hover.. it is a good heli but the cyclic response is somewhat slow..

hope to have helped you

[8D]Oh yes I have your site on my heli info folder favorites.. However, Having been raised the self-rithious american way(not always the best) and only being able to read and write english, I find that some of your comments go in and out of english and the rest I think is eather tiwanees or maybe cambodian? It doesen't matter I'm into the global thing for sure. Any way alot of the info I'm unable to retreive, but I refer to your info as much as possible and appritate your contribution to the hobby.
And yes I still have my DF40.I built myself a hover jig and used it only two days befor I was off of it and back to the RADDs ground school.
I get gutsey and bring her up (usually by acident) but because the jig helped me learn how sensitive the tx controlls are I don't even come close to crashing, I just set her back down. Once its up though it slides around alittle but since I set the pitch as you recogmended it shfts on the trainning balls very smoth and as soon as my tail motors get here I'll be able to lift her off without spinning, even though it spins it spins in one spot now and I think my hover will be much easier now. thanks a ton and let me know if their is some thing that will help translate your info on your great site...

wow you placed a very big rear wing.. isnt that heavy.. or will it cause the tail to be heavy.... nice color all black.. what did you pit in the window? it glitters green.. cool hope to see you hover more.. I'll be trying to get my DF40 back up in the air.. he might already missed me and gets jealous of the the DF60, since it arrived I was always focused on the DF 60 for upgrades and leave teh DF40 grounded... ill try too look at it over the weekend and check its parts..

About the language on the forum sorry about that its mostly filipino cause the site is managed by filipinos so most of the langauge are the local ones.. but I'll try to post the next tips in english.. like the one that I already started for the DF60... hope that i could help you on your DF40.. its a very good CP starter heli... it helped me to learn hovering the hard way but it made me more reliable and my skills developed mechanically.

If you plan to get another heli.. if its a 36/60 or the new ones 61/62 i bet you will hover easier and the flying experience will be a treasure....

[:@]Stupid me, I spent some time in the phillipines when I was in the navy... Not hotel street but the jungle and villages. The food was great, you folks are fabulus. I was E.O.D. and spent a lot of time in the chow hall...use to go back to the phillipino area and visit the phillipino cooks for lots of really good phillipino cooking.
Well, the tail mods. I use a very light weight and strong plastic. I started with the tail scag. the stock one really doesn't keep the rear rotor out of the dirt. I'v burnt out two tail motors becaust the rotor hit the ground and stopped momenterarlly, long enough to burn the motor out so I extended the stock one. After that the horizontal fin looked to small so I modified that one. Over all I added 8 grams to the heli. Also, I added a small red styyrofome nob to the top of the rotor, this helps me consentrate on watching the rotor head while I learn.(works very well. I lost some of the sight in my left eye when I was injured in a heli crash in cambodia so the glitter green helps me see the heli at a distance better then anything else) [8D]
If I have any questions about your site and have a translation prob could I ref this page to you for a translation? Were probubly the only two left in the world with a DF#40, most people go for the upgraded version. I'm already looking into a logo 10 kit but may purshes a DF400,#35 from someone who is getting out of the hobby, it the same size as the 40 but has many upgrades.[X(]


[8D] I look forward to the next time we talk LOL Dannoh40 & his fly right boys[8D]
