I'm planning to buy the Morris "The Knife" soon.
I'd like to build it stock.

Are there any upgrades (pull-pull) that I should consider or that folks may feel I can't live without?

It comes with the pull pull on the rudder and elevator. Make sure they work smoothly before hooking them up. Put a decient engine on it. I have a Webra .50 and it is AWESOME. Mine has no bad habits and flew right off the board. I did mount my tank on the outside of the fuse, opposite the engine. Great plane, you can't go wrong! Pete

Great plane, flies great "Stock". I would mount the tank outside the wing for conveinence but thats the only mod I would do. I have an os 46 fx and have plenty of motor left for pull out of hovers! A ys 63 will fly these nice too, as thats what I have on my su-do-khoi! Great Plane you'll love it! Probably the best hovering 40 size plane I have flown, and I have flown many! Happy flying

How does it compare to the sudo do koi or top cap in flight performance. Also, what is their best giant scale fun fly?

I have one of these and i have a about 25 to30 flights on it and the pull pull set up on mine works fine.

I just put one together (the arf) stock with no mods. The pull-pull looks wierd but works fine so far (about 8 flights). GREAT fun fly plane but not the most graceful thing in the air. I set up an elevator/flap mix as well as an elevator/ throttle mix. Lots of fun landing into a slight headwind with both mixes on, the plane just settles down gently like a helicopter.

My tail wheel bent first time out (landing vertically) you may want to upgrade it.

Lots of fun.

The giant su-do-khoi is an easy flying plane. It really likes to hover! The knife hovers a little better than the su-do-khoi in my opinion. But the su do will do the neatest climbing flat spin I have ever seen. Both are excellent planes. Of you are new to hovering I would go with the knife. If you are already hovering the sudo or the top cap might make a better choice. They are just a little wilder. I really don't know why the knife hovers so well but it does. I learned to do rudder touches with mine. The plane almost makes me look good doing it too.

Geoharry and all...
Thanks for your input...it's exactly the info I'm looking for.
I've seen other posts suggesting an upgrade to the tail-wheel.

Now that we have helped you, how 'bout sending us something from Honolulu! Pete
