Before purchasing a bypass from BVM, check to see if their system will fit/work in a Viper. I have a P-160 in my Viper and in one of my conversations with a tech at BVM, he gave me the impression that the BVM bypass would be somewhat difficult, if not impossable to install in the Viper without major modification. This is simply a heads up and not fact and I am not quoting anyone as saying it wont work. However, you may want to research before spending the money.

On a seperate note.... I have about 20 flights on my Viper now. Each one gets better and more fun. I have had no gear door issues as some have. I am not running a bypass. I still need to increase aileron travel to get better vertical roll rate.

Just my 2 cents!

Enjoy and happy holidays to all Viper flyers, builders and soon to be builders!
