Kinda odd that they sell all the individual bits....cuz once they're glued, you're "screwed". Sort of an all-or-nothing proposition isn't it?

They used to sell just the fuselage...can't find it on the new web site though.

Probably nothing a quick call to them via the old fashioned land-line wouldn't solve?

Finaly got a chance to mount the motor in the fan yesterday. Had to do a little scrubbing at low RPM but the fan is surprisingly smooth at high RPM. My numbers show 25A on 3s, and 41A on 4s.

I was pleasantly surprised the fan hatch is held in by screws! Does everyone else use this method? My kit didn't come with screws that appear long enough, but some servo screws seemed to do the trick. I'll still secure the fan with a little epoxy/hot glue, but the hatch should be fine with screws.

But then you snap off the wings and vertical and elevators??? Don't think that would be viable. I don't get what selling the pieces individually gets you...

Just finished mine; gonna head to the field and see if I can put the maiden flight on it. It's very windy today after all-day storms yesterday, but we're hoping for it to calm down atound 5:00 - 6:00 PM. We'll see what happens and I'll report back here!

Amx

Just maidened mine this weekend. Really fast! The colors scheme makes it hard to see in bright sunlight. At half throttle I would say it was running around 50. Watch your control throws also. Unfortunately I lost my orientation and tip stalled it into the ground on the third pass. No biggie I have a F5 on it's way! Great workmanship

I agree about the throws...keep 'em small and use 30-40 expo if you have it. Also, keep power into the turns or you may see yourself stall out if you're just cruising 1/2 throttle and then start to pull it around...

Love this little thing though....

In the review of the F4 here on RCG/Ezone, I thought it looked pretty comparable performance wise? It should be pretty close, as it is essentially the same power system and I think teh airframe is as similar size too?

Arron did a good job on the review and the video ... check it out if you haven't already?

Oh...I've read it plenty; I expect it would be close, but the devil is in the details...The F-4 shows ~ a half ounce lighter and has an extra 3 Sq inches of wing area, while on a smaller airframe. I'm figuring its a long shot, but I'm looking for anyone with first-hand experience with them both to offer some thoughts.

Winds never stopped blowing below 30 MPH today; the maiden will have to wait for another day.

A safe choice!!! Too bad, though; I enjoy reading others flight reports to compare to my own...

It will fly soon enough. This will give me a chance to change a few things about the airplane though... I had to do some funky bends in the elevator pushrod wires to get them to attach to the control horn straight. One side wobbles a bit so I may check my spare parts to see if I can replace it with a better-quality clevis. Also, I had to hog out a massive amount of foam inside the airplane to fit my 4s 2500 mAh battery, and even then it's still a little nose-heavy. The battery is barely attached inside the fuse so I may rework that a bit.

Maiden flight yesterday was a huge success! The AMX only needed a click or two of trim and it was flying stright and level. I'm surprised at how smooth the JPower fan is, especially since it required a fair amount of 'scrubbing' when first assembled. A fried took some Doppler readings; 86 MPH upwind and 96 MPH downwind (we were fighting some wicked crosswinds most of the day). I'll split the different and say it's a 90 MPH jet. It would probably be even faster with a higher-quality battery. Amp tests show 41A on a fresh battery.

JPower 64mm stock fan
Don's Wicked EDF 4000kV
Don's Pentium-40 ESC
Hyperion 4s 2500 'CX' 18C lipo

Even though the Hyperion battery doesn't hold it's voltage under load like my MaxAmps packs, I am impressed at how it doesn't get too blazing hot in the cockpit of the AMX... especially since I didn't cut any ventilation holes yet. The battery is warm, but not too hot to hold. I've taken the pack down to 14.3v twice and replaced around 2200 mAh into it, but it continues to perform well. I'm also saving WOT for high-speed passes and in short bursts; the rest of the time I'm at 1/2 throttle and the plane scoots along just fine. Flight times are around 6 minutes.

Oh yeah, and it will ROG (rise off grass) with no problems!
