You are not the only one stopping up now and then John. I want to get the lower wing done before boat and garden will take most spare time next month. However, if the point is to enjoy building (in contrast to get a plane ready to fly) one should only build if the desire is there, so there is an internal contradiction there.

Hi John, mine is the same, a very slight curve upwards around F6F7, I cut my formers from the plan. Two explanations, 1. I'm lousy at cutting formers accurately, probably truesmiley or 2. Lindsay did it deliberately to avoid the possible 'starved horse' appearance if it was dead straight. However not enough to worry about.

Same on mine. It would change the character if is would be a straight line. The sides curve in too.

Good choice. I will use its smaller brother. The 3542 800kv. That runns at 6000'rpm with a 4cell lipo and an11x7 prop. Just under 500W and is very quiet. Have used that on the Ballerina and a 60' Avistar. It combines very well with a turnigy AE regulator. I use the AE-45. Runs cool wil gentle acroflying

Hi John

Have you been able to get any idea what the dihedral on the lower wing is. I cannot find reference to it at all on the plan.

Cheers

Peter

It shows dihedral brace on the lower wing plan Pete, you could plot it off that or make a template, not read Lindsays blog but i think he fitted to one panel and built on to it ?

I extended the bottom edge of the dihedral brace out to the span length and found the dihedral was about 1/2" in total. I think more aesthetic than adding anything to the planes stability.
