I am scratch building a Livewire Jr Champ, cutting all the pieces by hand. Everything basically built as per plans (wingspan 35" and length 24") except I widened the fuselage by 3/4" wider at the nose, 1/2" wider at the saddle area, and 3/8" wider aft fuselage. And I made it into a tricycle gear instead of taildragger.

It has a AMA10 .061 that I am wondering if it would be too small to power it adequately. The plans call for a .049 engine. With the widened fuselage I am wondering if a .09 or .10 would be best.

Please advise.

I think you have a nice model that will fly quite well on the .061 Norvel.. The Champ isn't an Acrobatic Championship Contender, looks odd doing Harriers.

Just wondering where u got the plans?

Here's the big brother --- should be able to scale to what size you need.
