Got my X50 in the air over the weekend also. Overall good, but I need some tweaking and adjusting. I have the head dampening is a bit too stiff for the rpm range I want to run, want to bolt on some longer 620 blades and different paddles since I want to lower the revs, and need to tweak the power system a bit with some smaller packs and a different pinion. Flew it half a dozen times thought and did some old-fart smooth 3d and a gazillion autos. It's very smooth with no noticable vibration whatsoever.

You are living proof that you can get 10+ minute flight times on a 90 size electric!

That's great! Post up a photo if you've got one so we can check out your electric version.

I'll bet you'll be getting 15+ minute flight times

not flying it very long as I'm working on setup,.. only 7~8 minutes using 50~70 % of the pack. Gotta get gearing right and get the correct size packs. These are way too large and heavy but the only things I had on hand I could use. As a side note I did spin up the E720 a little higher and I can "only" get 10~10.5 minutes now if I want to leave any reserve in the pack <G>

Thanks for asnwering here in area we get the kit with 4 diff engines tt53 /56 or os 50/55 + two mufflers & not to mention the aluminum & bearing upgrades for the kits I planning to take the plunge but JR Vibe 50NEX is also looking very tempting especialy with the flybarless sytem.
Very soon the flybarless head for the X50 should be available...

I managed to get the X50 out to the field this evening, and finally got a few laps in! The motor fired right up, and I mean instantly, I barely touched the starter and it was running.

First impressions? This thing is light and is going to be fast. The servo setup is exrtemely quick, and the tail feels awesome.

Unfortunately I only got half a flight, the blades were slightly out of track and I wanted to adjust them so I cut the throttle. Once I got the heli back to the workbench I found that I had a couple of millimeters side to side play on the main blade grips. The bolts were still tight, and I didn't really want to take them apart at the field (at the risk of losing something). So I called it quits (it was getting dark anyway), and brought it home to figure out what happened. I also noticed that the engine started leaning out towards the middle of the tank, so need to tweak on that a bit too. More news on all that once I take the head apart.

In the mean time, here are some pics of the flight, and big thanks to my buddy Bob for trekking out there to take them!

I'll bet you didn't have the dampeners pressed all the way in when you built it hence you didn't put the correct amount of shims on the blade axle to adjust the end-play.

Small update, after running around all weekend at Fly for Tots, I've been able to get back to my workbench and sort the head out on the X50. All is done and ready to go again, but now I have to wait out this rainy week. I'm shooting for Saturday morning, so I'll post up how everything goes!

Saturday morning is washed out! I'm waiting for a break in the rain so I can try to get a few tanks of gas through it, I'm really eager to get it in the air!

[QUOTE=CSpaced;27735]I finally made up all the ball links, and used a few extra parts to make up a push/pull link for the throttle. I've programmed the swash and levelled it all out, and all that is left is to program the governor/gyro, pitch and throttle curves. I ended up choosing a Hobbico Life Source (PO4) 2100mah 10C battery, which fit perfectly into the receiver tray. I use a couple of these batteries in a 100cc extra 300, and they work great.

Here are a couple short videos of the X50E prototype. I'm not a smack 3D flyer but you can still see the performance level of the machine.
I've fitted the Titan SE canopy which is a touch larger and bright yellow due to my old eyes.
