My new toy!

CH and Toff, thanks for the warm wishes and yes, she is fine, at her home resting comfortably.

And, as promised, here is the new baby in all her virginal whiteness! And the video of the flaps in action!

NICE!!!!

Good for her, glad all is well.
The Cub is looking great, I love those big wheels!

Toff,

Toffa it is then. Roger, over and out!

wish you the best for your daughter.

great looking wing set up. cooperative weather is touch n go these days so lets cross our fingers for good conditions for you, your plane, and your family!

Would mounting a down facing camera on the plexi-glass be an option? Would be an interesting view on the world if you ask me.

Well, maiden didn't go well. Flaps down, she jumped in the air from a grassy field in about 3 feet, flaps up and started to make a circuit around and suddenly she wouldn't turn left, reduced speed and continued to try left turn when she just spiraled down in a nearby parking lot. Lots of nose damage and messed up front bearing on new motor.

Repairs done to fuselage and found the bearing at a place near my work. Will pick up tomorrow and then see how it goes.

Still not sure of cause of loss of control, but suspect failure of one of the control horns I had used a glue other than CA.

Hope it all goes back together smoothly for you, JK. Having had a few MPX planes, I will say to use epoxy rather than CA. I think it gives a better bond on elapor, and has a little bit of flex in it, whereas CA always seems to dry brittle ( for me, anyway..)

Jk,

Sorry about the wreck. I know that feeling when the best laid plans go out the window and your pride and joy falls victim to gravity.

+1 on the epoxy from toff. I find a nice liberal application holds everything and indeed retains a little plasticity.

Get her back in action and call a mulligan on that maiden. I know I've had to call one or two in the past and am not looking forward to the next one.

Inevitable...

Think I finally figured out my control problem, and of course, it was pilot error (I feel like an NTSB reporter, they always blame the pilot, don't they?).

Just before my maiden, I re-read the manual and noticed a section talking about differential aileron travel, 22mm up and 11 mm down. Without thinking about what I was doing, I used the end-point settings on my transmitter to limit the down to the recommended 11mm, full travel already gave me approximately the 22mm up travel. BUT- I measured this on the right wing only, and since I was using a single servo (two servos connected by a t-harness and by using the end point setting I was inadvertently doing the opposite for the left aileron! Therefore, I could easily turn right but didn't have the throw to get it to turn left!

After asking about using solder wick as a binding for U/C, what should drop through my door than this months RCM&E magazine! Containing:





Hope you can read it, it is quite interesting!
