Actually, I tried many of the electrics. The problem with the one Super08 is showing is that the mounting pattern doesn't fit. The plane has to have the gear drop from the mounting side down. The motor and mechs have to be on the opposite side of the one shown in order to work. There are none like that, and believe me, I've tried a lot of them. If the fuselage wasn't fiberglass you could build a mount, but to make all three electric -- with the work involved -- wasn't worth it to me. And I already had the nose gear which dropped right in.
I had some used Multicons. The new ones are FAR superior in my opinion, and do not require the box inside the airplane. And they were 5/32s, not very strong. Just my opinion of course. Ask my wife, my opinion is not worth a lot.....
