I've been flying a 20lb + model with a TJ120. On 12s you looking at between 4.3 and 4.6kw. I think you'd want at least 5000 cells, if not bigger. I was using 8000mah but it was a bigger plane that could carry the weight.
Could be interesting.....

It's done.

Just ordered the TJ120 edf unit + Neu 1915-1Y motor.

I already have a CC 120amp HV and that should work.

What do you think the AUW will be using the TJ120?

My guess is something between 8 - 10 lbs, but we shell see.

I intend to use 10cell 5000mAh for day to day flying with an option of a light 12cell, first I would like to bench run and see some numbers before I finalize on a setup.

Looks like I'm going to put the fuse aside till I get the fan (Dont want to install the newly cut motor bulkhead or the ducts till I get the fan unit).

Anyways, I decided to start woring on the vertical fin.

As you can tell by the pics, modification of a functional rudder is on the way, tomorrow I have to stop at the hobby shop to get some wood and some robart pin hinges.

I've seen the Stu 100 mm in an 18lb F86 and it flew awesome.

How would a modern 90mm 8-10s setup perform in this bird, wouldn't that be a lighter setup? Yes this bird was designed for 120mm, but wasn't that back when everyone was running NiMh's? The size of the plane also points to 90mm.

A 90mm fan on 8-10cell setup would fly this thing easy, personally I don't feel like going through all the extra work to convert it to 90mm.

But would be interesting to see how she would fly on a modern 120mm.
