RE: HARMON ROCKET
 

Just got mine yesterday and am glad to see so many guys enjoying the plane. Got a JBA Engines .56 with it. Have not seen anybody use this motor is it fine or should I look for something else?

I've never heard of JBA but assuming it's a fairly normal .56 2 stroke you should be fine. Enjoy. :)

The weight is lighter than the evo .46 but puts out a bit more power. Hope it's going to be a good one.

That should be fine. Mine zooms about the place with a supertigre .60. Make sure you brace the horizontal stabs and do something about the soft landing gear (wire braces between the les works fine).

well i have flown mine now with the TT Pro .61 on a macs header and pipe. Sounds awesome and really zings across the sky. I maidened it before switching out the gear and i think until i have problems i'm going to leave it alone. Sure it springs out some but it sure makes the landings soft!!!

Hui all,

I am interested in this HR3, and does anybody know the thickness of the wing ?

Tnx

RE: HARMON ROCKET
 

Although I don't have mine nearby to measure wing thickness (for sale at local hobby shop), I can tell you the HR3 has a very thick wing. Despite the thickness, it is quite fast and handles real world maneuvers of all sorts well, but is not a 3-D machine. It is quite easy to fly and easy to land.

If mine doesn't sell soon, I might keep the plane and install a 4-stroke engine.
