Knowing which plane it is, I did a little research . I think its actually the "Powerline Edge 540". That plane is designed for a 46, so be careful with the ASP 61 on the nose. It will be more powerful, but its going to be a lot heavier (probably 225 g or 8-10 oz) than it would be with a 46. From the pictures it lootk to be pretty lightly built, so be careful of the engine mount/firewall. Making it heavier on the nose will also mean you'll probably end up adding some tail weight to balance it. That additional weight will make it closer to the dreaded tip stall on approach.

Was my thoughts exactly. With the 46 it was way too tailheavy - had to add A LOT of weight inside the cowl on the firewall to get it too balance. With the 61 it's a bit too much nose heavy for my liking, but I guess one will only know once I've flown it myself. The guy who maidened it landed it pretty fast but it didn't seem too be stalling on low speeds in the air - once again this I will only find out later.
But you saying it being heavier with the 61 certainly isn't a understatement. I actually want too go balance it myself again tonight and just see how much it is nose heavy and I'll post it just for interest sake too any people who wants too know. Like I said with the 46 engine is was extremely tail heavy with the battery also mounted right infront of the plane.
