Just didn't have the time/reaction/realization (whatever) to notice the attitude getting worse despite the input... So sad.

In what part of town are you? I'm in the Montavilla neighborhood... if that's meaningful!

Hi Dag...

You really hate to see something like that....but the thing that gets me are all the guys standing in the "line of fire" for those four props at the beginning of the video....
And the same thing in the video for the Sea Fury.. when it is first run, it is pointing towards the spectators. I just don't understand why other people don't understand what can happen when a prop comes off.

One good thing about your B-36, is that even if a prop came loose, since the thrust would be towards the front of the plane, it "shouldn't" come off....

I still vote for a failed range test. Or TX Antenna down...

I've seen it happen before. Usually looks almost exactly like that.

Maybe even RX Battery failure as soon as a real load is put on it?

I'm going for no on the stall. It just doesn't look like it.

Maybe it's my young but very bad eyes, but to me it looks like he's trying to roll RIGHT. The left aileron looks down, while the right one looks up. I'm wondering if he was having engine problems, combined with an overweight/underpowered model.

Mt Scott Area. Yeah I know in general the Montavilla area. Fly in Washougal with the Fern Prairie Modelers, and out in McMinnville with the McMinnville Aero Modelers out off Mason Rd. Fun fly there tomorrow.

And now Back to Dag

Not trying to beat a dead horse, but the lighting shows the left aileron in the up position. As the aft, upper portion of the wing is in shadow, a down aileron would be in at least as much shadow. The left aileron is definitely lit up by the sunlight, showing the upper face above the shadow.

I'm through, now!

This might look familiar... People standing in front of the plane during the power-up test and stalling just after takeoff. IMHO, both attempted turning before getting enough airspeed with an underpowered plane and the lower wing stalled. Although the reflection off the wing of the B-24 does make it look like the left aileron was up. Nuttin like a good pre-flight check.

Now back to your regularly scheduled, Dag's B-36 show...

Hi Guys.....

No crash on this one, but it sure seems to me, that the gentleman flying the plane really needs to learn how to co-ordinate aileron and rudder, as the left hand turns all seem to really skew, with the tail dropping to the left....

As you can't just buy a RTF plane that size, you would hope the pilot had some experience beforehand and was competent, so I'd like to think it was another reason. BTW, why were there two guys with transmitters?


Sorry to clutter up the thread with another non- build related post. Hiya Tony S, good to see a few other Aussies watching too! This biuld sure has created some attention, the mind just boggles...

Re B.24 my two pennorth says the left aileron was UP and was held up, I think ailerons reversed. I've done it myself and you just keep bending the stick that way because you can't accept it's reversed!!

Hi mate! There are two guys on transmitters because once you get these mammoth models, there are more than enough controls for one pilot, so non-major functions get assigned to the co-pilot (like with full-size. Dag is planning this too.

That B-29 video was kewl but IMHO this video has more to show. Pilot and co-pilot WITH you can see in the video some one monitoring Tx's and RPM checks and good safety practices. Some pre-flight planning.... and a little bling to boot.

R/C B-29 with X-1 rocket (7 min 23 sec)


With all the finess Dag has shown so far and his attention to detail, I'm sure this B-36D maiden will be top of its class and be a prime example of "what to do" to be successful and throw in some fun too. I may not be able to attend the maiden cause its on the other side of the US from me but I am definatly looking forward to the video.
