ORIGINAL: v8mini
just totaled my second Showtime 90[
], I'm thinking this model isn't for me so will probably look for something else to put the MVVS 26 into.
only got 6 flights on this one, same as the first. not totally sure what went wrong this time, but i did notice a couple of times when i banked to the left and pulled some up elevator the model seemed to decide to bank to the right. when it actually crashed it was going in a bit of a dive(not fast) and i couldn't level it out not just from elevator but also rocking from left to right on the ailerons. before i knew it it was in the ground.
initially i check the radio gear and all servos were working ok, and surface hinges and linkages in place and move freely, but looking at the bits when i got home one aileron servo seems to have limited movement on one direction and the rod is slightly bent, will have a proper look at it later.
not too sure where to go next, think i need more of a sports pattern plane instead of a 3D type model, one things for sure i don't get on with Showtime 90's
edit.... just stripped the servo down, a hitec HS-925MG. it works ok under power, but to move by hand it has a bind spot. on the final gear there was a slither of metal from one of the teeth and it now has a step in it and still binds in that spot so will need a new gear. this is a result of the crash rather that cause.
Dude, this is something that a Showtime usually do.
Maybe you just figured out it to late, but it is not your problem, it's an aircraft design problem, so don't keep thinking bad about your skills. There's nothing wrong with you.
In fact, the Showtime has a huge (I mean HUGE) snap tendence. And this behavior can be worst if you decide to use a heavy engine. And Your MVVS 26 is truly a heavy one.
Mine is with an OS 160 FX. When it was in the beginning, I got the same problem as you, like a suprise. I was flying in a very high altitude making a rolling harrier and, than, when I stoped to roll, the plane just turned inside and stalled baaaadddd!!! I have the video. Probably happened the same with you.

But I was lucky and the plane did not crash, and than I just got what I should do to keep it flying and avoid those snaps. So I learned that my Showtime works this way: High speeds all the time. Slow speeds and full rates just in high alpha position.
Mine is alive yet, but I don't have any pleasure flying a plane that can crash for nothing. The truth is the Showtime is not a plane to heavy engines. Maybe you can get a Funtana and install a bigger engine. You can harm some flights features, but nothing like happens with the Showtime.
Maybe a good plane for your engine is a Nitro Planes Katana. I am crazy for one, but they are not selling here in Brazil. [&o]
