I need to update my firmware, I'm currently on ver 0.6.0.2 which has the reverse affect apparently, starts the timer at zero stick and stops the countdown above that, which is kind off funny - Obviously have to update my firmware tomorrow! Still made me giggle though

Off topic, but I did say I wanted a build, which meant I wasn't much drawn to the combo kits, so I just pushed the button on a Tarot 450PRO V2 Flybarless Basic Kit / Silver, which came with free shipping from MM which was cool. Will probably still get a 250 for xmas but I just want to build a half decent 450, something to tinker with! Not going to order any parts until I receive it, then will order what I want and start the build.

Off topic I know, sorry guys!

EDIT: Anyone know any decent, active Tarot 450 FBL threads?

You can reverse this. Go into "Stick Postion Switch" and set "ON" to High.
I just tried this now before I posted this.

Good idea. I will add it to my blog and also to my reviews that use the Devo TX.

Your welcome, glad I could help out!

I really like using the throttle stick to start and stop the timer.
I just did flight times for my Hoten X review and set my throttle stick for stopwatch.
This is much better than using my hand timer which I have to hit start and stop every minute to measure the battery voltage.

I flew EP200 with 2702V but never got any blockout problem cause I don't use such powerful servos that may eat out the current form BEC. Also I had checked out there would not be any binding issue in any situation that may raise the current flow greatly.
Your input is appreciated. I agree about the BEC. Though there are many others flying these same servos/RX with the stock Walkera ESC and other ESC like Castle ICE 50A. Maybe not the same Hobbywing platinum ESC i use. My heli flew fine with the last RX for around 30 flights. Then i install this one new one, and an immediate repeat of the same issue which cost me hundreds of dollars with the last RX i had with this very same issue.

I do have a new V500 with the new Rx and it flies fine with no lock outs even in hard 3D. The firmware is just not that great for Manny's type of aggressive flying (and I don't like flying the big helis anymore) so she sits in my hobby room collecting dust. Its unfortunate that Walkera did not keep the firmware from V1 (which flew amazing) and flashed it into V3. Hopefully there is an update coming for the 2702 soon.
I greatly appreciate you chiming in on this. Sometimes i just get worked up. It's nice to know I'm not completely crazy sometimes. I know people flying big helis for months at a time with no crashes except dumb thumbs. I've only thumbed my v450 into the ground once, and it was recently. Otherwise every single crash has been failure related and i have rebuilt the V450 with all new electronics. My 4f200 required just as much replacement of parts. But after they flew great! Except the thes 2 particular 2702V. I have no doubt right now i could take my other v450 and fly it with the "good" RX. Then if i switched out the RX for either of these other two "bad" ones. I'd get a total black out in 30 or so seconds. I'm just not going to try it I hope wow can get them exchanged though Walkera. I was sooooooooo mad!

In Florida, no static this time of year. Humidity is at 80%-100% until, well, always! But it's always a possibility, i suppose.


Thank you all for your help, comments or criticisms about my v450. I have not heard any stories like this when people use Spektrum TX with a RX and Microbeast or 7200BX on Gaui X5, X7 and other helis. Though in the manual for the AR7200BX it does mention that when using it on 500 and bigger size heli that a "satellite receiver" should be used. The idea is it adds antenna to compensate for "blind spots". So i plan on getting an X5 with BeastX. I'll definitely give my unbiased opinion after spending all the money on that German BeastX tech. Weather or not it's worth it, well, i'll let you know. I also plan on trying the 130X and nano out.

So far NO Walkera heli i have tried competes with the V120D02S right out of the box. I'd put my money on the V200D03 as being nearly as good right out of the box as well. Now with all the upgrades i put into the V120d02S i can do prolonged 3D, slow tick-tocks and all kinds of flipping and rolling all over the place. The 130X main blades really completed the performance with the heli. But those light blades do not play well with the gyros, especially in wind/gusts. One last thing, i took the 130X tail blades off. They were just horrible. They looked good but performed not so great. I am now back to the stock type blades. The heli is more stable now i think.

I had my timer set on the mix switch before this, but this is much better!

Can't comment on the rest of the stuff mate, I don't know enough, but I know you like to see your blades (don't we all!) can you not use the V120D01 tail blades, if memory serves correct (and it rarely does) they have a spot of yellow on them and I would think would be a perfect fit?

Those are the very ones I installed tonight, yup Have not flown yet. Just test hovered using them in the drive way. It was pitch black out so i just wanted to see if it would hover and hold the tail right. The extra weight on the tail rotor seemed to smooth out the flight.

You know. On my v450 i don't really care what color the blades are. The tail blades kind of look nice when they are yellow though. But you just don't need to see them as much. I don't actually ever look at the tail rotor for my orientation, so it's mostly just to make things match. Looks good on camera too. Showing off is fun if you can right?

You aint wrong mate, its got to look good, thats part of the fun is it not Figured with the yellow on them they would look good with the yellow blades, I have the yellow blades en-route, so will probably fit the D01 blades as well if they fly ok on yours (I wont be doing any 3D obviously!) - but they will match, which is always cool aint it!

I agree, I tried the kdbb 130x tail blades, they would not hold. What works for me is to take a toe nail clipper and cut about 1/8" off the stock tail blades. Then I can turn the gain up to like 78, which makes the tail hold much better. With regular stock tail blades I had to turn tail gain down to like 65, which makes the tail kind of sloppy on my setup (2s governed 4600 rpm).

The D01 blades will work fine. Same type of blades on all these v120 sizes. Just different colors.

Where did you get a Governor/Governed ESC for such a small heli? I'm fairly sure if i go 100% throttle on the 215 motor and 130X blades i'm at around 5k rpm. I'll have to tach it some time. I don't like to run at 100% i've settled around %70. Which is probably around 4600 rpm or so. Not sure, never really busted out a tach for these little ones. Just guessing. I'm not sure i would prefer a 2S setup. But a governor would be sweet if it actually kept the head speed steady and functioned properly.

You know you can get a Gaui X5 super combo with a microbeast for $899, or is that what you're taking about?
