Lanier Explorer 40 Trainer conversion?
Hi everyone: Moving from glow/diesel to electric so please bear with me.
I'm in need of help to select a motor , ESC, battery to power a Lanier Explorer Trainer.
Plane specs :wingspan 64.25
wing area 695.5 sq in.
WEIGHT 4.5 - 5.0 lb
I was thinking about an AXI 4120/14 but I'm not sure.
Esc?
Battery , likely NIMH for a while and then id like to try LiPo.
I would like a 10min. flight time if possible.
Thank you Wade James

RE: Lanier Explorer 40 Trainer conversion?
An excellent choice of motors for a generic .40-size conversion. There are several threads on 4120/14 applications in this forum. Greg Covey and I are big fans of these motors, and recommend them frequently for .40-.50 size conversions.
Check out the tables at www.modelmotors.cz for cell count and prop size recommendations. An 11x8 or 12x8 on 16 GP3300 NiMH cells ought to give you the 10-minute flights you seek. If you want to extend the landing gear, go with the largest prop you can get, and reduce the cell count to get better efficiency and lighter weight. Greg's got a couple of 4120/14 applications running 12 or 14 cells with friggin' huge props. Your trainer might look a little goofy with the long legs and huge prop, but you'll like how it flies
I've also powered a .40-size trainer with a Kyosho Endoplasma, 4.6:1 gear ratio, 12x8 prop, and 10 cells. I get 8 minutes if I stretch it on CP2400s, so with GP3300s, it should do a full 10. The 4120/14 solution will give you quite a bit more power, but it will be heavier.
