After waiting weeks for the rain to stop.I crashed it on the maiden flight. Then the wreckage was stolen! I lost everything. (AJ Extra #1 is in the crappy avatar pic to your left) I got a new one and started all over (I hate doing things twice) Put 5 flights on the new one last weekend. I'm finally over it. What Extra 330s are you building. I love the Fliton model. Check out the thread. "andrew jesky fliton extra build" Be warned that it is very long, but has everything you need to know about the plane, and more.

I didn't want to wait till mid April for my Beaver from Horizon, so i cancelled it and bought one from Turbonut on this thread. I received it today, but I have to put some final touches on the Extra first."

I may modify the wing to a "2 piece" design, for transportabilty. I may also add some wheels and front casters to the floats (like I've seen in some photos) Then I can take off and land on pavement, but still fly with those cool floats on. and the Float/wheels add even more character.

Take note that the intake scoop is actually located 180 degrees (radially) from the model photo. It should be on the upper right side of the cowl area.

Better luck with the new Beaver, Gary
The AJ Extra is what is hanging on my wall in the basement now. All I need to do is finish up the elevator and it's done. Very nice plane.

Power Setup

I have a strong motor I am using in a 7.5 lb plane (HXT-50-52B). This motor is rated at 480Kv, 50A, and 300g. It is a big motor that I use with a 6S2P 22volt setup and draws over 800 watts with a 12 x 7 3-blade prop.

I plan to use this motor in a 6S2P setup (2 3S1Ps 2200mah in series) with a smaller prop to get about 600 watts in. Is this too much motor for this plane? Any thoughts?

Hope it aint an omen. All my flights canx today due to woxoh.

Good Luck to all the other maidens occuring today!
I live not to far from you and you know how it was yesterday. Well I went to the field when the rain broke. I set all my throws on the bench at the field. As soon as I took the plane out onto the runway it started raining again.

I just waited about 15 minutes and the rain broke again. That's when I maidened mine. The plane does like to weather vane into the wind. So be mindful of that.

Good luck on yours. Maybe next weekend you can come up to my field and we can fly together.

Yeah that sounds too heavy. I was using the power 25 and had to push my batteries back a little to get the CG.

The Power 25 weighs about 200G, so you might be able to get away with it.

In Acton ( about 20 from me) is a place called Parker Mtn (also called Vincent Hill, I think) It's a mountain ridge top, just wide enough for a dirt road. People slope soar up one side, then down the other. It's an awesome sight. VERY, VERY, FAST and exciting

Very cool. I hope you enjoy it. There are some pics of mine on the AJ build thread: AJX#1 - pg 356; AJX#2 - pg 365, 370

I am going to add a little flat black to the front of the two scoops to simulate holes. Easy touch up and makes it look better.

Once I get my servo's in from the LHS, things should move very quickly.
I'm on the way to my not so local Hobby shop 50 mile drive to get my Beaver. I had one on order at hobby Zone but canceled the order, don't want to wait till April.
Too bad the local Hobby shop here is worthless! I don't know how they stay in business!

My 4S1Ps Fit!

Finally got the fuse out of the box and trial-fitted my True RC 4-cell 4,000 MAh
battery. I have to slide it to the rear , lower the front and then slide it forward into the "cage" but there's plenty of room for it. Lots of space to move it back and forth to adjust the CG.

Assembly Sequence?

So I'm looking at the assembly manual. It wants the LG put on first then the motor and ESC, then the cowl......

I don't like the idea of adding all that weight to the fuse before I have the tail glued on. Methinks I'll do the wing servos first, join the wings and install them, then do the tail. Work on the fuse can wait.

How are you others doing it?

I went with the landing gear and motor first. I like seeing the motor in it and had very little time to work on it. Can't wait to finish it.

CR,
I started at the nose and am working my way toward the tail. I used a straight edge and the stab mount is perfectly square. I will install the servos, radio, cockpit etc. before assembling the wing.
Had to go flying with my Aspera today as the weather was so nice

Flying stuff put away and back to the building bench. I have the flap servos operating on a Dionysus Servo Rate Reducer. Seeing the flaps go up and down slowly to me seems more realistic.

Made it back from the hobby shop with my Beaver and everything needed for the 25 motor. Got a good deal on a Thunder Power 3300mAh extreme series.Total: $633.0
Also ordered a Spektrum DX6 with the AR6200 recever.
This is my first ARF so I'll get some help from my friend at the RC club.

You could do it, but those batteries aren't going to give you much flight time at 600W... The Power 32 with
the recommended 13x6.5 prop on a 4s 4200 pack will give about 5 minutes at WOT... your setup will give about 2.

Now, since you're going to be cruising at less than WOT, YMMV... but I still think it's the wrong setup for this plane.
