Default 4*40 ARF

Hi,
I can't find any posts on this plane.
Anybody got one?
What changes were necessary during assembly?
Thanks,
KW_Counter

ps: Posting in Beginners also

I just saw a brand new 4*40 fly this weekend with an OS52FS in it. No mods were made to it, flying on a grass runway. Very nice plane, the pilot says it is one of the easier ARF planes to assemble and fly. You will really enjoy this bird. Just watch the control throws. My friend is says it is jumpy on high rates, and therefore has turned down to 55% on low rates. Now that is very jumpy!

P.S. It flies much like the sportster, only I think the 4* has a little more maneuverability to it due to the different airfoil. Good stability even in moderately windy conditions.

Good bang for buck. I bought it after seeing many posts for it being the best second plane
you can get. I am not sure about that, but it does fly well. I did encounter issues during
the build. Some control points I did not like and bought stronger stuff at the local shop.
I also did not like how they wanted the control rods to wrap around the fuel tank. It really
put a stress on the servo. Still don't have it right were it is free flowing.
Coming from the beginner side of things I did not think it was as easy to put together as
some say, but it went together in the end. In the air it is VERY STABLE and you have to
force it to stall. Landing is a piece of cake as it slows down slower then a trainer. I have
landed it at a crawl with only a foot or two roll. In some ways my landings greatly improved
with this plane instantly. I am running mine with a .46AX and it is
MORE then enough power and as lite as the wing is it seems to handle the power well
with no sign of stress. Good luck.

I haven't seen the ARF, but the kit built version was one of my favorite planes. Great flier, noble and predictable. Aerobatic capabilities were great except for knife-edge. The BIY design was notorious for being weak in the tail area: the stab-fin joint NEEDED triangle stock reinforcement (without them, any snap or spin could tear them off), and the area where the fuse meets the fin needed fiberglass reinforcements, as it was quite prone to breaking on, hmm, un-gentle landings.

The kit always built nose-heavy, requiring the servos to be installed as far back as possible and the battery to be installed behind the radio compartment. It would be easy enough to add a hatch back there to facilitate installation and access.

Good luck,

Here are a few pics of the finished model I mentioned earlier. Both static and in flight.
