RE: Apprentice 15e
Good luck with tht, as great a trainer as the apprentice is... I think they reverse engineered its parts to NOT match up with anything else they make. The motor is less kv than the "power .15" its also 22mm longer than park 480/450 therefore it wont fit most cowl . The 3200mah battery needs alot of space, and the 20 or 25 amp esc (depending on which site you look at) is not enough for a plane the size tht the .15 will go in. an dont forget the 8mm hole you have to drill in any prop but the factory one... I am still scratching my head on tht one.??
I am thinking about making a mount and strapping it to the front of my alpha450 and see if the rudder can handle warp-drive !
