As something to compare with - a Super Cub wing loading is roughly 13 Oz/ft²

Yes, I'm not overly impressed with this plane other than its unique looks. Stock motor is too wimpy and adding a stronger/heavier motor (also needed to get the CG where it needs to be) only makes it heavier.

Yes, the stock motor is too wimpy. It will provide just enough power to fly, and not much more.

I am putting C3536 1100, it is heavier motor, but my home made motor mount is lighter. The stock motor/mount is 155g, my replacement is 150g. What will effectively (without adding extra weight) correct the CG is the battery relocation. When I finish all improvements I will post some pics.

Overall advise - if you are not comfortable with modifications/alterations of your new plane and looking for a well designed airplane straight out of the package - this one is not it.

I do love the way it looks, I must admit

Yea, that motor would probably work, but it's still on the light side as far as moving the CG. If you're moving the lipo way forward you'll be ok.

I was NOT impressed at all by the stock prop. I would suggest a MasterAirScrew (MAS) 11x7x3 instead. You can still use the stock spinner with it too...

Good luck!

I'd sure use a 40a esc as well with that motor & prop. The stock 30a is going to be iffy at best...


Get one of these:

The BEC inside is of the "switch mode" type which means it can safely power more servos when under a load.

Stick your stock motor & esc in the classifieds here on RCGroups and recoup some money


Have fun!

This motor is a good choice. 40A controller (up to 6 cells LiPo and 4A BEC... - nice!) is also a good one to use for this motor. It looks like a good combo

My first brushless motor I began learning to fly with my good old Super Cub later went through several planes (with some very serious mishaps in between ) and is still working - using it now in my ParkZone Spitfire.

well little more progress done. i stopped by the lhs and they had some master airscrew 11x7x3's, so i picked up one, along with some du-bro 2.25 r's. did a little rolling in the grass in the back yard and much better now (than foam wheels)

just waiting on a buddy and ill be ordering new motor/esc!

i did ditch the wheel scirts for now, to balance the weight change on the new wheels. plus they restrict it in grass i find

i only fly grass feilds around here so rog is big for me

My plane is almost ready. Just a few minor things left to do. Here is what it looks like...

The CG is about 70mm. The main wing grew a liitle bit wider... oops! (I hope Scale Police will let me get away with that ) I did not like the trailing edge, so it is much sharper now.

Cessna 400 Corvalis (1 min 3 sec)

It is a good idea to have those wheel pants off...
I will keep mine for now, may take them off later... We'll see
