HIROBO Freya - Sceadu - Shuttle > Tough day with the Evo 50

Man what a weekend. I finally decided to get my evo going after it had sat ignored in the corner for the past year. I had this weekend free and worked on it feverishly to fly this last Sunday. Well I must have stayed up too late working on it Saturday night because I had forgotten to put the servo arm bolt in for the tail rotor. Well as I was test flying it in my driveway the tail gave way and started pirouetting uncontollably and I put it down on the concrete a little hard (read: damn hard) breaking the landing gear and a part of the main frame. Of course it also scraped up the BRAND NEW carbon blades and carbon tailblades!!
Needless to say I was pretty PO'd. But, I was now on a mission to get her in the air. I had made plans to fly this particular day for the past week and probably wouldn't have a free weekend for a while. I wasn't going to let this "minor mishap' get in the way. Soooo, I ran back to the 'man cave' and started putting her back together. I found some old align fiberglass blades, some very old thunder tiger black paddles, a set of plastic tail blades, I think from a raptor 60. Luckily I had a spare landing gear set. I found some Kwik JB weld and some carbon fiber strips and glued the frame back together in record time. Got everything balanced etc,etc.
I finally got out to the field and decided to get her started to do some flight testing.
Not!
I ran her up and noticed the tail rotor control was backwards!!!! checked the direction, nope, it was ok, checked the gyro, nope it was correcting fine. Well I shut it down to check what the hell was wrong now and discovered that I had put the tail belt on incorrectly and the tail rotor was actually spinning backwards!!!
I had taken the tail off to dynamically balance the tailblades during the first crash and put belt on wrong. Anyway I finally and very tenatively got her in the air after all of that. She did fly very smoothly and responsively just like I remembered, just gotta get the better blades etc back on. Just goes to show what happens when you get some "gotta fly-itis"
What a weekend!

Tough day for the Shuttle Plus Too

Not to worry, you were not alone in your blade bending this weekend. I put a few slobbering rich tanks of gas through my new OS .37 in a Shuttle Plus. Started leaning a bit for better performance and once running reliably I took her out to the runway for a few patterns around the field.

The wind came up and on one gusty landing I touched a tail rotor blade to the runway surface and pitched a nice new MS composite blade off into the wild blue yonder. The violent shaking that ensued after that shook my boom supports loose before I could get her shut down. Thankfully the main blades are fine but the rotor housing, tail shaft, blades and blade grips are a write off.

Turns out the UK heli carbon fiber vertical fin that is sold for the Shuttle is way to short to keep the tail rotor from striking the ground. Its the same with stock 77? or CF blades of 80mm. I've seen others flying in videos with the same configuration and its obvious that the tail rotor will hit if your not careful. I thought I could get away with it for my engine break-in this weekend. Not so!

Not sure why UK heli sells these fins for the Shuttle when they obviously dont work. I sent them an email about this small oversight. No reply as of yet.

You guys think you had a bad day, one with an evo 50 and one with a shuttle plus? The club is growing.

Shuttle Plus a couple of weekends before that.


Man, I miss the eighties.

Heres my story. I traded a 1500.00 computer to a friend for his sceadu last week, got it all setup for Sunday I even put a new tail boom on it, I hate to put boom on, so i am out flying around I came down the runway roll after roll went to bank out to the right and it kept going strait into the ground. it wasn't to bad but the new tail boom isn't new any more. So here we go back to the man cave for some more wrenching..
I think the reason it crashed was the radios block came loose. lost all my cyclic control..
so check those radios blocks.

You guys are just crash noobs. :P

I piled my Evo 50 in inverted at about 60 mph. the carnage was strewn over about a 15 ft long swath. I think she is totaled. I havent had the heart to do a post mortem yet. I know the frames are broken in at least 5 places, probably need gears for all the servos, and I only had three flights on the new blades. Its ok. I really didnt like the way the radix fly. Now I have a chance to go back to Vs. (Yay!)

At least the cabin is ok.

I came, I saw, I hovered
