I'm curious...why are the tips of all control surfaces shaped the way they are (slightly swept)? Why not square/taper them off?

I flew it tonight, what a floater!! Even with the stock prop it has great power.

Power off on downlines it doesn't need brakes, so I'll be trimming the supports off the rudder soon.


Knife edge is going to take some getting used to, I've programmed my hands to feed in too much rudder to keep it up, and this seems to hold knife edge with almost no input at all!

Definitely a nice design, if I can find somewhere to fly it I may just build a full size one as well!

Congrats on the Mayden!!! I am thrilled that someone else is enjoying it. Now you have me wanting to build a 50mm version.

As for the full size I was flying mine in TO a couple of weeks ago. Here is a picture and I'm a shame to say it but I dont remember the name of the person flying it .... I let everybody fly my plane. I try to show poeple there is more to indoor flying then Embers and UMX planes.

Next time I'm in TO we will have to fly together

On these slow flying indoors the only real effect it has is good looks.. It take a little more then that little surface to make a noticeable change in flight behavior. I did ad the surface to the root of the aileron to ad surface in the prop wash and increase control in slow climbs and hovers... I think those actualy work.

I was going to post the plans, but it's 3 times the file size allowed for pdfs, if anyone has any suggestions for how to reduce the size I'll try it and post them.

I was just wondering how much weight milling usualy saves? It looks like it would take a lot of effort.

A heavily milled F3P model of modern size 850mm span average can see weight savings of between 6 and 10g typically dependent on the Depron used.

Thats up to 10% of the rtf weight of the model

The Alien


I fly F3p because they give me the greatest satisfaction of any indoor planes. I give alot of seminars and workshops to try and get more people flying this type of plane. My workshop include all building technics that we usualy use when building F3P depron planes. I also encourage people to try there hand at designing there own. My son Alexandre has been following me and asisting my for two years and now at the ''mature'' age of ten he asked me if he could design his own plane, I said yes and this is what he came up with. We call it The Alien. It is more of a freestyle plane and I cant wait to give it a try next weekend. All of you wondering if you can do it, this is the work of a ten years old!!!

OOOOOOOOOOOOOOOOOOOOOOOOH...

For some reason I read "Gene Bond" as "Gene Blond". No wonder I couldn't find it!

Well she flies great, to fast for F3p but I think she would make a great freestyle plane, Alexandre says he has never been as comfortable flying a plane and I believe that, there something special in flying your own design. The pics show the plane in hovers and torque rolls but that is only because it makes it easier the capture both the plane and the pilot in the shot. the plane does fly nice and true.
