I'll test out your theory Rafa tonight after work.

LIke you said it is normal for this heli. Mine does the same thing. If you give it a little more throttle on liftoff it will lift straighter. Its only when you feather the throttle too little on takeoff. I think its cus it is FBL and 3 axis gyro. I am bored with mine already so selling it if anyone is interested->

Do you have rubber dampeners on your landing gear? This is necessary when taking off from hard surfaces. Or you could try using a foam mat.

Hey the foam mat sounds like a good idea. I think i'll make up a new helipad surface. Thx

Ok, I need a hand here.

I bought the 4F200 BNF version as I already have a 2801Pro, my problem is that the stock settings have the ele and ail reversed, so I reversed the servos required until they were correct and planned to use the swashmix to change the pitch from + to - but I can only do that if I switch the swash to 3 servo. In 3 servo mode though I'm having difficulties because the ele and ail are not responding correctly. Does anyone know the correct settings for the 4F200 bound to a 2801 pro in 2801 mode?

Updated parts!

Hi Guys,

I had a nasty spill the other day that took out one of the main servos again. I can't really blame the servo, as I was surprised that more stuff didn't break. The new servo set I got from Wow includes the longer servo arms. I like how Walkera will update things mid-run.

Also, I would advise checking parts out before taking them out of the bag they come in. I received an unfinished tail rotor head the other day, and also a tail shaft that was manufactured incorrectly. Wow has told me to send the parts back for replacement. Like I told Jonathan, for as many CB100 parts as I've ordered, I don't think I ever got a bad one. Just a head up,

Rafa

Decided to drop the price of my 2 X 4F200 BNF package. Down to $250 for both if anyone is interested.

Wish I had $250 and some room for a few more helis. With my 2 year old running around, out-of-reach horizontal space is precious.

In other news, I just received a pack of washers today from www.mcmaster.com. P/N 91116A110. I got them as spacers to run the wood or plastic blades that others have been using. I haven't flown the heli yet with the wooden blades, but I bolted them up tonight and I think it's going to work just peachy.

I'll let everyone know (Anybody left in this hanger? Seems kind of quiet around here lately.),

Charger/battery questions?

Oh yeah, I've been meaning to ask a few battery questions. I'm still using the stock charger, and I've got one of those little voltmeters from wow. I've noticed that on both my batteries, the second cell always seems to be a bit lower voltage at the end of charging. The first cell will usually be 4.21V right after charging, the second might be 4.19V. Normal?

Also, one of my batteries seems to charge in about 2 hours or less, my other battery can take 3.5 to 4 hours sometimes. The battery never gets warm during charging, but the charger does get a bit warm during the middle of charging. Both batteries are right about the same age, use, etc (actually, the longer charging battery is the newer of the two). I'll fly a pack for 5 minutes of flight these days, and it's usually got 3.8V at the end of the flights. My suspicion is that the second battery, the one that takes longer to charge sometimes, is having a hard time kicking that second cell up over the cutoff voltage. Is there anything I should/can do about that?

That's normal with stock slow charger.You have to buy a fast lipo charger shorten charging time.Usually with stock lipo, average flight time is about 5' so make sure to time it on TX or you'll destroy lipo!Anyway, stock lipo is not ideal , just find some Hyperion to replace it.

Hi Guys,

I'm happy to report that with the washers listed above, my heli flies great with those wooden blades. I've got 6 packs on it since the wood blades, and I'm surprised how different it feels. It seems more stable, and the thing this noob notices is that it's easier to take off and touchdown smoothly. Seems like with the stock blades, while landing, it either wanted to hover several inches off the ground, or get sucked to the ground--not much room in the middle of all that. With the wood blades, it's easier for me to land gently and smoothly--for whatever reason.

I've ordered a few sets of the plastic blades to see what they feel like. Here are some links to the spacers, wood blades, and plastic blades. These links were copied from the parts post I did a while back: http://www.rcgroups.com/forums/showp...&postcount=214

Here's some washers that will allow one to use the wood or plastic blades listed below:
P/N 91116A110 at McMaster.com (mcmaster's website doesn't let me post the link like I'm used to)

Here's the wooden blades dkfuji referred to:

Here's the plastic blades Alwayscrash uses:

Happy flying,

Rafa

Anybody tried this with their 4F200 yet?
Close to ten meters per second wind speed flight Trex 450 Pro-class remote control helicopter.MOV (6 min 1 sec)

This is a 2612 rx on a 450. Would a 4F200 handle this well? Mine seems to bob a bit in the 5-8 mph wind I've been flying in lately. I guess the 450 does too, maybe he's doing a good job of controlling it. 9 meters per second is 20 mph! Seems like nose into the wind is the trick.

How would balance delay and other rx settings affect wind handling ability?

Here's where I am now. I learned a valuable lesson today, without spending any $ even. Don't spool down immediately, b/c if it's tipped a little bit, it's going to keep tipping. I say this because this flight had a few 'near-tips' at the end, but was able to straighten it up since I still had a bit of head speed.
