Yeah he has it all. My fan and motor are the ones you have been using to test fit. That's a 890Kv motor that I will change out cause that one will go to CN to test in the Turbax after I mod the front flange to fit the Turbax.

Is the Dynamax and the Dyn-e-max the same thing?

No, The Dyn-e-max is the electric conversion of the glow Dynamax fan made by Jet Model Products in Belton, MO

The Dyn-E-max uses either a Neu motor or a Scorpion motor. The XPS system uses the same fan but a Littlescreamer motor. The Dyn-E-max is rated to 4500 watts and ours is rated to 10,000 watts. They both work about the same on 12S with us being about 1800 more rpm's on those 12 cells, but you can run ours up to 16 cells and 10,000 watts with over 25lbs of thrust. Both set ups will deliver around 15lbs of thrust on 12 cells and 4500 watts. Hope that helps

Falcon 120 wing stress


Hi fella's, are you beefing the wings/Fuse to handle the stress on 15 lb thrust or is it OK as is, thanks.

Are you gonna 3D it If you fly it like a Jet it will be fine. This wing is really thick so it won't be fast anyway. Just don't yank and bank it real hard it will be good to go.

To strengthen the Falcon. I suggest reinforcing the landing gear blocks, front and rear. Everthing thing else seems to be fine.

I have discovered the rear deck can be weak, It may not be on all of them.

See this link.

I have a orange and black Falcon that does not have this modification with plenty of flights, but I will perform this modification on all of my new ones.

It is smooth as glass in the air. You fly it like a jet, it is all about energy management. Flaps are a must when landing. I drop them then fly with power to the ground.

I now belong to the Falcon club - needed one to determine how to make mounting tabs for the nacelle.

Welcome Jim to the Falcon club.............let us know when the mount is ready for sale....I need one as well as your motor/fan to fit the nacelle I purchased from XPS.
This is a really fun plane to fly and I am using twin Arc 36-75-1 on my plane. Little too heavy in my opinion so I am switching over to a single fan. You will surely need flaps on landing unless you have a very long runway.

I am thinking of doing my Falcon in some Russian dress since I am changing up the fan. Think I will do something like this....just for fun. The falcon is one of those planes which will fly for a long time as they are easy to fly so a little dressup would be nice......plus I can better take a look at the glued areas in the wings once the present covering is off.

I don't know if we will make the mounting plates, I was just after making a template available to our customers so they could make their own.

I have no idea what color the Falcon I am getting is!!
