First I'll answer the flap issue.
The flaps were not on.
The jamming is due to being past 20 degrees of flap the gap seal separates from the trailing edge of the wing. With the lift of air to the underside of the flap it causes the flap to lift up so if you remove from full flaps it can bind one or both. I had this happen the maiden flight and you could tell it tedered to one side but not enough that you could'nt correct it some what easily. I had 15 partial and 45 full as the instructions recommended.
Unless the flap servo went haywire......I find this unlikely. I also ironed the gap sealers down a 1/8 inch with an iron so I would not have this happen again.

As for the aleron getting stuck....I happened to me on the bench. I so worked it out to try and fail it there again and again. After the light sanding it took to get it cleared.
Through the first loop as I said at the top you will see........I had my finger off the stick when it rolled over.
But yes....it is possible it got stuck as a lot of other things are too but I just could not get any feedback to feel it was going to recover.
I have seen the other Viper that crashed and its very similar to mine. Although I did not have my gear down and flaps were not on and I backed off the power coming on the backside of the loop.
Hopefully that puts a little more insight.
Video I believe is done almost............
Ali Helped me a lot with questions on my build and responded quite quickly as I barely even know him. I appreciated that a lot. As this was my first jet.
I bit expensive......but if you watch my maiden you'll see I had little to worry about after hitting the landing the first try. They got even better everytime after that.
