i am on my second viperjet loved the first one so much had to get a second (losted first one to pcm lockout)
both are first generation the first had reg size hitec dig in ele-rud-flaps-aler i used todds bobcat covers on the tail
servos they stuck out a little it had sping air gear/ robart struts/ bvm brakes futaba radio ram 750p auto start
for power 21 lbs is just right for this plane was radar gunned at 187 full power get as much flap as you can

second one has jr 3421s in the tail /hitec digs in the wings/robart gear and struts bvm brakes
ram 750 p auto this one i am going to setup crow per tams photos

use the cg per book and get the most flaps you can

also both i filled the tail with 2 part foam to stiffen it a little
george from va told me about that mod

plane flys like a fast pattern plane
good luck with it
