I'm building a new BVM Ultra-Viper and have decided to do away with the flaperons. The plans do not show an option for separate ailerons/flaps unfortunately. Could any of you guys with an electra measure the root and tip chords and the span of the ailerons and flaps for me?

thanks,
Thomas

Flap root cord 4 and 5/16 inches,
Flap tip and aileron root cord 3 inches,
Aileron tip cord 1 and 5/8th inches
Flap span 13 inches
Aileron span 11 and 3/8 inches.
Had to go and get my wings out of my van hope this helps.

Ron,
that is Exactly what i was looking for! Looks as if the Ultra Viper wing is about 4" shorter per panel, and my guesstimate on flap/aileron chords was about right. Thanks for the help!

Hi Thomas,

could you pls post pics of your build as you go along?

thanks V.

I have an original BVM Viper kit in the shop somewhere in the room of kits to build. I am going to put flaps on it as well since flaperons washes in the wing when you put them down. Having flaps and ailerons for setting a little crow in the mix for landing is what really is nice for speed and decent control for landing. I use it on all my jets.
