Bandit builders....

I have a servo question for the flaps. BV calls out 8411's for the flaps, I don't have any on hand. I do however have 8611's, they fit in the pocket (just setting them in) but I ma not sure everything is going to line up properly.....

Can any of you comment on this, am I good to go with the 8611's? They are phyiscally bigger so I want to make sure I am not hosing myself.....

Please Advise!


TIA
