I love my umx Radian aka Baby Radian. Have learned a lot about how the AS3X works and programming challenges. Here is a series of links to forum contributions by others & myself.

after 18+ hours of flight time or 73 flights (batteries) [some crashes & hanger rash] the elevator froze. I decided it was cheaper & easier to just buy a new one. Many happy memories with umx RAD I. Now umx RAD II has some 'NO PUSH' livery to remind me not to bang it against objects. Working so far.

Ahhhhh... understand, thanks.

I just ordered one this afternoon (along with a new DX6) - looking forward to flying it!

Your "blog" was Very helpful, thank you.

Lennie,

You will enjoy both. The umx Rad is the only plane I have taken out of the box, did a quick pre-flight and flown with a smile. I do have to note two comments:

Make sure you read the blog item "~ Activating The Gyro - Read This First, click here ~" before you go fly & remember, it is a very delicate aero frame, so be gentle, patient & soft with it.

Wish you a high Fun Factor. I'll await your maiden flight review. Any questions, just let me know.

Thanks, George, appreciated.

Actually, I went through all items in your list earlier this afternoon - very informative, helpful.

Though it's of little import, but I've had a couple planes with AS3X... and know, first to manually trim Before activating the stabilization, and that to activate, pulse the throttle and leave it sit still for about 10 seconds or so.

Reading through this Thread still, but I know you are correct regards handling the little aircraft carefully.

I hope you're enjoying your Radian II... keep us updated on your flights.

Again, thanks.

Lennie,

One last thing not mentioned too often, if the umx Rad starts to porpoise while gliding, give it a touch of down elevator (& release) to gain a little speed, if it continues to porpoise, relax, land it & move the battery back a little. Usually will fix it. If this fails after two attempts, call me. You may experience this some days & others not. All I know is it works, usually.

I saw one flying today and I'm thinking of picking up a Radian, however, I'd really prefer ailerons. Has anyone tried to modify one with ailerons? I didn't get a chance to see inside of the fuselage by the wing. Do you think there might be enough room for a sub micro servo to run ailerons? I'm thinking of inboard ailerons (where the flaps would normally go). Does anyone have a picture they can post of the wing and fuselage wing bay?

I always like to put a little personal modifications on me RC Planes....

Thoughts yea or nea.

Go to the forum => https://www.rcgroups.com/forums/show....php?t=2089760 & select Thread Tools Show Attachments in this Thread (upper right hand area) to see the pictures that have been posted.

Personally, this is a glider that turns very well with the rudder. Have not seem anyone put in ailerons, even on the larger Radian, flaps yes. I would prefer to add the weight of a larger 220 battery than extra servos. I suspect due to the dihedral, not sure where you would put ailerons as the wing tips are curved up.
