Want a new motor for my Formosa but I can't decide which one to get.

HIMAX HA2015-4166 BRUSHLESS MOTOR W/ GEARBOX

Or

HC2808-0980 HIMAX OUTRUNNER BRUSHLESS MOTOR

Keep in mind I already have a 15A ESC and have no desire to buy another one at the moment.:D

My vote is for the 4166. I have both outrunners and inrunners.
Both styles of motors serve me well.
The reason for the vote for the 4166 is that it will be more
adaptable to different aircraft with the three choices of
gear ratios that are provided. That said, I think you will
be happy with either set-up.:)
Good luck,
Bear

If you believe in KISS, then outrunners are the ones to use.

The Hacker outrunner motors are much better than the Himax motors IMO.

What hoppy said - I do not like the Himaxx gearbox. The GWS does fine, but you would be better to go with a Hacker outrunner the a 20-22l on 3s LiPoly and a 9x6 prop would be a great starting place.

I use a motor similar to the Himax (Tornado). It flew great, but after about 20 flights the gears started getting noisy and eventually were stripped. Company send me a new one though.

I used an AXI 2808-24 in my formosa..and holy moley, It would move. Outrunners are not near as efficient as geared inrunners, but they are less troublesome (cant count how many gears I have stripped), quieter and great for planes using a semi-constant throttle.

Don't get the Himax offset gearbox. The gears are not strong enough for the Himax motors and you'll spend half you time trying to find the prop and prop adapter that won't stay on the shaft.

If you must have an inrunner, get a Himax 2025-4200 and a Cobri gearbox. Better still forget the inrunner, build the Formosa light (don't glass it and don't use three coasts of paint!!!) and get an AXI 2212-26 and a Cobri stick mount.

Another option with the Himax 2015 route is to go to www.e-flightline.com (http://www.e-flightline.com) and get one of the motors set-up with a Cobri gearbox. These gearboxes have larger output shafts and are very durable. I finally killed the bearings in one after putting my ACE Corsair in on the fourth "hard" nosed in landing after a receiver failure. The bearings were about $2.50 and easily replaced. With the setup I had, the 8x3.8 APC SF was spinning at ~10,500 rpm static.

Just another $0.02

Almost all my motors are outrunners; I only run one gear-drive brushless. However, the Formosa is one of those planes that I think will profit from the flexibility and efficiency of a gear drive.

Matching plane and motor is science up to a point, then art. So we're all just guessing (how _you_ build the plane is an important part of it all).
