RE: Seagull Harmon Rocket
It’s been a bad week for flying. Firstly I put my OMP katana profile in, (pilot error). Then two days later my trusty workhorse Seagull Harmon Rocket suffered terminal tail plane flutter after performing some split S`s and went it very fast with complete lack of elevator control.
The tail plane has snapped in half on either side of the stab. The only thing holding it together is the elevators. Worst of all the battery broke free on contact, striped the wire and shorted out, frying all the electrics. The lesson here being don’t cable tie the battery lead to tidy it up.
The plane only had an Irvine 46 so was not exactly over powered, in fact I was considering a bigger engine for it. I had joined the two elevators together with 3mm rod, running from one s3001. I had used the supplied pushrods which at the time seemed sturdy enough. I had even filmed the hinge gaps as I do with all my models.
This was a fantastic model. It is brilliant value for money at around £90 and easily the best quality of finish and least amount of construction from any ARTF I have ever built. But I know someone else in this thread had exactly the same failure so be warned.
With hind sight I would have strengthened the tail plane, maybe braced it. I would have also used better pushrods and maybe a better servo.
The plane is in remarkably good shape considering the speed at which it hit the ground. I won’t bother repairing it; I might as well just buy another at £90.
I would still recommend this plane to all from novice to experienced pilots. It makes a great windy day bash plane.
BTW the Cof G is spot on with the Irvine 46 up front and only two standard servos in the tail. Battery was on the servo tray.
