Well, I finally completed the trim flight of the converted and would like to report what I have done.

What I feel important things for a successful conversion are as follows.

1. Trim weight from the glow engine setup as much as possible. Since an electric motor vibrates much less, lighter weight material can be used instead for frames, firewall, etc. On top of that, two 5000 mah battery packs can weigh as much as 2lb 11oz and the outer runner motor 21 oz. One has to trim the weight everywhere to meet the 11lb weight rule.

2. The current design of popular f3a motors suitable for 2m pattern planes calls for big E-props (e.g. 20.5" or 21"). The old landing gear good for 18" prop does not provide enough prop clearance. A tall landing gear is needed instead. In the Sequel, I decided to install a fixed 9" CF gear. The total weight is 4 oz. The landing gear servo will go.

3. Two 5000 mah packs take space and for Sequel I decided to access them from the bottom of the fuse. Originally I thought about opening up the canopy area for the purpose. To save some labor and maintain the integrity of the CF fuse, I decided to let the two packs hang vertically from a deck with Velcro strips. It seems the idea worked well.
