Hi All,
Just thought I'd write a quick post as I have just rebuilt, setup and flown a Bean E4. I have flown one before but this is the first I have been able to really sit down with it and get to grips with the workings of this 450 size model. One of the guys I fly with unfortually had an arrival with the ground unexpectedly and was short of time to rebuild it. So I got the chance to work on one.
Ok, I though another 450 same old same old. Mmmmmmmmmm. How wrong I was!!!!! First of all I noticed the whole layout of the model was what I can only discribe as extremely simple.
Certainly as I got further into it is very easy to work on. I had to do a standard crash repair (main shaft, bearings, flybar, boom, tail shaft etc etc). Nornally tacklling this on say an 450 V2 I might have put it under my bench of shame in my garage for a bit, but no need with this one. Tail shaft was changed in 5 mins. See picture below. You undo the two screws that hold the bearing in and pull the tail shaft out. Quick change and back in again. Nice
Onto the boom which was a case of loosen the boom clamps at the back and front. Pull the main shaft out, slip the belt over and pull out the whole tail assemby. Once again very simple. Also the way the boom is clamped at the front of the model is effective and will not wear out. No more slippy booms.
Next was to reinstall the new main shaft, flybar which was straight forward. The feathering spindle is held in by two nyloc nuts one on each end instead of bolts. At first this idea didn't really excite me however thinking about it , I actually believe it is a good idea. The ammount of times I have put feathering spindles in and locked the outer thrust race bearing up with loctite or fitted it with no play and running free then wondering if I have put enough loctite on. With this system all this goes out the window. Slight draw back is that you will need two small nut spiners to get the nuts off the spindle. I think EvoRC will be getting these soon.
This re-build really didn't take me a long time and was quite enjoyable.
Onto the flying part. A couple of the guys from the club said you would be impressed with the acturatcy of this model. 450 size I thought, Naaaaa never. The Rave is very acurate but this is running 350 blades so surley not with only 325 blades. How wrong was. Very accurate. Goes exactly were you point it. Stops where you asked it to and is lively on the cyclics.
I am impressed. Only thing is I have to find some money to buy one now
Paul, if your busy and haven't got time to pick the model up, no worries mate i'll look after it for you a little longer 
PS: Anybody want to buy a 450 V2
