Nice work Matt, another great little design. Should scale up well for a larger fan also.

Hi Eric, yeah I am thinking about a 200% pusher version for the Park Jet motor I picked up on sale at Hobby Lobby a while ago. Come to think of it I also have a couple of XF fan/motor combos lying around. Those will probably find their way into something sooner or later.

Thats really cool, I want one. Esprit man its too cold for me to fly right now but I'm glad you did. Excellent plane. I second Eric's vote to go 56mm yep.

I've cut out the parts but am confused on step 2 (pretty early to get stumped, eh?)
You say that I sand a half circular channel in each piece of foam... I see the wings (pgs 6,7,8) as one piece of flat 3mm foam. I don't get the "two pieces of wing should come back together..." unless the wing consists of 3 parts - the one I mentioned that's connected to the fuse, and two other ones that are sandwiched on top... (which I don't see in the plans...)
Sorry to be a dolt! Don't see it...

Thanks again!

Hey Joe,

Yup the wing panel is one piece, what you need to do is cut it from wingtip to wingtip (I think this is mentioned in there somewhere) and sand a groove in each of the cut edges so the carbon rod fits inside when you glue them back together. The trim line is marked on the plans with a dashed line.

This method is a little bit more work than gluing the spar to the surface of the foam, which works great but doesn't look as clean.

Oh..... so I cut right through the wing all the way across (cut it in half)!

Oh, BTW - do you think I can get by with 9g servos?

Depends on the size of the 9g servos. I know the Hitec HS-55s I use sometimes would be pretty bulky for this jet, and they're around 8g.

I think it could be done since there is plenty of room in the fuselage for larger servos if you mount them further forward. The extra weight is an issue but it should definitely fly.

F-22 thrust vectoring COOL


found the build very impressive F-22 with the thrust vectoring and the manual is also done very well

Great job on both the kit and the manual also to share what you have done with everyone...

What you came up with is a great design that flies wonderful.

You should be very PROUD and also to share this with us...that's what it's all about this RC hobbie that we can't get it out of our system...

It's a sickness....good thing they don't have a pill for it.

Thanks Chuck - I've learned pretty much everything I know about RC from this site so it's nice to give something back.

Hi Matt,
I was so impressed by simplicity and elegance of your design that I started to make one for myself. I build the body just to discover that the DF I have is GWS50 and my Feigao is 1208436... much lower kV that it should be used. Besides I have Losi 8750 and bateries 2cell 730 and 3 cell 520. I was thinking of creating a workable propulsion system from those components... any advice? I do not need jet performance, just a nice stable flight. My thoughts are that I build light enough the Losi motor combined with DF50 on 2 or 3 cells should do the trick.....
Best regards,

Hi Janusz, thanks for the kind words.

The EDF-50 should fit although you will need to enlarge the existing fan cutouts and move the servos forward to clear the larger opening.

I haven't tried the 4100kV Feigao in any EDF setups but I understand it isn't so great. For a pusher setup with a 3x3 DD prop on 3S it is quite impressive though.

Don't know much about the Losi motor, it may be too hot for an EDF-50 even on 2S. I would try some bench testing to see what works.

Good luck!
