Well for first time I just got a brown on blade 400 and got a $30.00 worth of crash.

Broke feathering shaft, blade grip, blade, boom, and finally landing gear. Didn't know that I can get a brown out but it was about 50 yards away, and it was about 25 feet up in the air as I was heading back to me and suddenly got a brown and lost control as it tilted to right and crash straight right sided. As I put it to hold mode and that saved from getting any more damage to bird, but would need to double check the RX since I knowested the couple of brown out before but didn't think too much but we'll have to see.

Will give more photo update soon. :)

Lube the belt to stop static build up that will mess with the rx

I prefer Tri-flow 'cause it has teflon but lots use silicone too.

LockMD Thanks for reply, yeah didn't think about that, I do that on my 450 but this used 400 first time use and it was flying great so didn't think too much on it, but should have been carefull with it I guess.
replacing main shaft also, didn't look too bad but just in case, since I broke the blade grip pretty bad...

I dread the day I have to replace the main shaft and the belt.

Hope Sokal's build videos will cover that or I may have to fly him out here for a cali vaca (so he thinks) so he can re-build mine. :YeaBaby:

Well LockMD, I just found out that I had to replace from rotor head since My screw broke off on main shaft so whole thing need to be replaced. :( its not going to be easy since I have replace belt and tail also.
I'm going to rebuild from ground up since I found couple of area where main body broke so I will be rebuilding from servo to all the parts.
I got this heli used and found that lot of parts were upgraded but those parts are going to be in my new 450s. I will be fun rebuilding from ground up I hope :rolling <-- yeap my head will be rolling really bad I guess. But I think it would be same as building 450s or other heli.
I will keep you guys on what I find out or make videos after couple of rebuild I guess.

Hey LockMD Just do it. half the fun is working on these things. I have replaced the main shaft about 5 or 6 times and I can do it blindfolded. I have removed the belt and replaced the tail shaft also. How does this speak of my hovering skills:arggg:

Hey dont rush me, it doesnt need done YET (knock on wood) just saying I dread when the time does come. I did have to replace the boom, but just took the tail off leaving the belt intact.

You can blame the crash on something else. You may have flipped throttle hold, but it would not have activated throttle hold if you was having what you call a brown out problem?
What is a brown out as you call it? and how do you know this was the problem?


I have replaced a main shaft in the Blade 400. Takes about 10 mins to replace. The only problem the jesus bolt sheared. So I had to take a punch and drive the part of the bolt left out of the main shaft. That took another couple of mins. LOL New 2mm bolt and model is flying again great.

Well I got this heli used and didn't check for all the range, which I should have done, but what can a 2.4 go wrong... well it seems like at about 25-35 yards if you have your heli noise in well systems locks out. I tried it with my friend and asked him if cycles are moving at distance and around 25 and on response is slow or doesn't respond. I'm thinking that it might be caused by something else but I want to find out before I go flying around, or try with my 9303 and see if I see the problem.

Yeap you are right crash is crash and it was caused by me and can't blame poor TXs :)

never had a lock out like that before and my buddy who was watch heard me say OH SHOOOOOOOT. and bam it drops on right side, not sure if I lost power as well but I don't think I lost power thats why I put it on hold since didn't want the whole heli to have headless chicken dance. left stick was all the way down at the same time :)

Can learn anything if you aren't taking chances right.....

Just picked up the last pieces and should be able to finsh tonight and see. Will be doing range test before every flight for sure now

but what can a 2.4 go wrong...

2.4 ghz is great because no frequency pin or checking for someone else being on your channel is needed.
But it is still a radio frequency and is capable of having interference where ever it might come from.
I was at an event this past weekend . There were 175 registered pilots. Out of those 175 I would say 155-160 of them were using 2.4 ghz. Yes there were some problems with the 2.4ghz systems. Don't know exactly what caused the problems for the ones that had them. But it was interference of some type. So treat 2.4 ghz just like you would any other frequency band. If something is going to happen it can happen. LOL

I had a problem with my DX6i At about 40 feet I would lose controll I didnt notice it until I was able to fly outside. I did a range test and it was about 3-4 feet. I called Horizon and while I was on hold I just thought to try an antenna of my cx2 radio. It worked My range test went up to 75 feet+. When they answered they wanted me to send in my radio. I think I will only send the antenna since my radio works good with the other antenna. I had a bad connection to the tiny connector at the end of the wire. I hope they will fix it.

Dave I didn't think too much since 2.4 works great with my other helis and I forgot that 400s belt were robbing on one side and I think it was causing interference. after taking the tail boom out I saw the part of belt were worn out showing sign of wear by robbing. I will be replacing the main frame as well and basic doing complete rebuild. Finding too many things so oh well back to drawing board I guess. :)
One good thing is that I know where all the parts are and know what will go wrong now.
Will be back up flying shortly with Blade 400.
