With 40 + HXT500 and HXT900 servos installed and in use over a period of at least 5 years I have only had two failures. One was a damaged gearbox caused by a crash and the other was a burnt out electronics caused by a BEC failing and dumping the full 2 cell 7.4 Volts onto the servo. Neither of these failures was the fault of the servo.

The HXT900 are even waterproof. This was as proven by my 5 minute total immersion test in an earlier post on this thread. http://www.rcgroups.com/forums/showp...&postcount=327

Hmm. An interesting test, but don't forget depth of water makes a big difference.

I would be surprised if the servo was at the bottom of just an ordinary bucket of water it would still be waterproof. I have done this with so-called waterproof containers but they didn't pass the bucket test and of course if a 415 sinks it could be at an even greater depth.

The sure answer is to CorrosionX ALL electronics.

A good point...except that this is a foam plane. Even if the hull was completely filled with water you could not sink it

Realistically, all you need is for your electronics to be water resistant. As long as the servos are protected from spray, they should work fine. If you have completely submerged it, then you probably have other damage that will make the loss of a $5 servo not really such a big deal.

Yes, but maybe not the 415, but I have had an EZ glider Pro crash into a swamp & the motor had enough weight to keep the nose down low enough so by the time I found it the water had ruined all the electronics.
With CorrosionX it will save your electronics even though the plane didn't wash up on shore until 2 weeks later

Has anyone tried the Hitec waterproof servos on the tail? Also, is the spray really bad on the tail servos? I concerned about putting a good quality servo on the elevator but there really is no way to put it in the fuse with a ling push-rod...

Any ingenious way of attaching the canopy/cockpit, magnets, hatch clips, build wood frame, etc?

I saw someone used 2 pilots , it looked great. Remember what scale they were?

Thanks

The canopy already has a tab at the front and a magnet at the rear.

I added two more magnets at the rear on either side to give a more positive lock. As well I placed a layer of petroleum jelly on each side of the mating faces to improve the sealing. A bit messy but it works.

I applied some soft rubber window sealer in self adhesive strips (from hardware stores) around the cockpit Fuselage side) & the fuse wing saddle.

Looks OK & it should povide reasonable protection & was easy & cheap to do

I enjoyed your video. Very nice and smooth scale type flying.

I particularly watched the take off and landing to observe how much spray came off the hull. I was very surprised to see how little spray was generated and the fact that none of the spray came anywhere near the exposed elevator servo.

Did anyone use the glue the kit comes with to assemble it? I'm about to put it together but wondering maybe if I should get some 30 min epoxy instead.

Finally was able to get this bird airborne! It took several tries. She still seems a little nose heavy in the water, however in flight seems to be well balanced.

Even on the maiden I had several attempts trying to get a decent takeoff run. The water rudder only seemed to work half the time. I'm not sure if there was some underlying current that was negating the rudder?

Here is the maiden flight:

Motor Mount

Howdy,

Hoping one of you guys can get me pointed in the right direction. I'm fairly new to planes in general, and this is the first one that's had a stick mount for the motors. I have these motors, as suggested by HK when I placed the order:

http://www.hobbyking.com/hobbyking/s...dProduct=18544

I ordered these mounts, but the offset betweent he stick centerline and the motor centerline appears to be too large, so I'm not sure what I need:

http://www.millenniumrc.com/MotorMount.html

Can one of you fine gents point me to the correct mount to use with my motors on this plane (preferably from somewhere in the U.S.)?

Thanks in advance.

The mount I used is this one. http://www.hobbyking.com/hobbyking/s...idproduct=3613

The round mount is removed from your motor and the new mount is slipped over the tube projecting from the rear.Then the pinch bolt is tightened. Two screws are put into the side of the square part of the mount lock the mount onto the stick.This mount has the correct offset.
