I saw this fly at FFO'19 and I enjoyed watching it. I hope to build it at one point.
I was great meeting you and talking shop about this and other flite test / hobby things.
well from experience I can tell you I have my EDF about an inch or so aft of the CG with a thrust tube all the way to the tail. If I mounted it aft like you have there ( which I did). It comes in very tail heavy. With a canopy to protect the battery and a 1000mha battery, I had to add 4.5 oz to the nose to get barely neutral balance.
Just finished the maiden flight. Used a 9 x 4.5MR APC so when I get a chance I am going to explore with different props. Took off at 1/2 power. I can build, but I can't paint or get the dye off the FFFoam. So that is my downfall.
Will it adapt to a 64-- JGplanes?, you bet it will!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Going to set it up building with the TV off and then on.
You built an excellant model JG, ever think of molding a nose for the plane? The design is so simple to cut and build.
Pic above was to show I'm going to do both prop and 64 EDF.
I am first enlargen the size so I can find where CG and where to position the EDF in the future.

Since I am going to use a 1300 3s for both, going to do things slighly different so I can adapt to the EDF once I get a feel it.
For my setup with Thrust Vectoring, the added weight of the TV at the exhaust will require me to move the EDF forward. Don't want to add additional weight for balance. Will build another model for the EDF.
Are you reducing the exhaust nozzle diameter?
Awesome! Sounds like you had a great maiden.
What do you mean by “molding a nose?”
Yes I am reducing exhaust, can’t remember what my exact ratio was but I think it was 80 or 90% if fan area. And length was about 3.5 to 4 times diameter. Thrust vector might be fun but it is twitchy and easy to lose yaw stability already, other side of that is TV may help spin recovery.
If you look at mine I built up a small “canopy” on the nose for the battery. On a larger one I may make it a bit more sculpted and bring it further forward for a different look ( more space fighter or cruiser).
Oh yeah JG all three of mine got home mostly intact👍🏻
Did you know that if you reduce the exit area you increase the exhaust speed, but you reduce the thrust output of the EDF?
