I have flown them with both a120 and a 140. The 120 is more than adequate if you keep the over all weight down to around 27lbs, which is not hard to do with this jet. I prefer the 140 because I like a little more thrust authority. Landing is about the same with either.
if you are operating from thick grass the 140 might be preferable.

I should have mentioned that I will be flying it on paved runways in the Phoenix area where elevation is not an issue.

UK’s favourite Rebel scheme ready for a flight. JetCat P-130Rx-B
JP gear, stock pipe and tank…nearly all U.K. Rebels are like this, none add the aftermarket heavy tank.

The CM Jets tank is a better design than the stock tank. It is shorter and wider and places more fuel over the CG. Therefore there is less of a shift of the CG during flight. If that sorta of thing is important to you then the CM Jets tank is a worthwhile investment. However, the Rebel isn't that sensitive about CG and folks running the stock tank don't complain about it.
My small Wizard had a horrible tank layout with all the fuel in front of the CG. The CG would shift 1" during flight. For that small aircraft it was too much. Early in the flight much up trim was required and it changed as the fuel was consumed. I re-engineered the model and now the fuel is centered on the CG. Much better now.

So just building been as well; the flap arm is .75" . For The ailerons, I'm using a durable plastic arm for the clevis pins, .80" as the arm just exists the slit opening.
The Elevator will be .75" on a carbon arm from MKS, $7 an arm . Rudder will use a .80 arm for the clevis but if it doesn't fit will go to 1" with a ball link to clear the opening slit.
Hope this helps Vegasking.

The classic is my first build of this type other than a foam turbine PNP. The one thing I haven't decided on is the servos. I see the MKS HBL599 servos on sale this weekend for a good price. Would this be a good choice for this plane all around except for steering? Also, any suggestions for a steering servo?

I have two sets of 599's two Imac planes and they worked very well over the years. The 9930 is very good and I prefer the coreless in servo in the jets, if it fails it won't stay locked over like the brushless servos can.
On the pro or Max size Rebel the 599 for flaps but I've used 9930 on flaps with no issue on my Rebel Pro.
I just ordered six 9930 from Aeropanda yesterday and our Canadian dist would only allow me four servos, kinda sad they limit stock on black Friday sales.

I wanted to do the 599s for my Classic but due to huge price difference i went the 9930 all-round and Savox 1270+TG for flaps. My lhs (d-m-t in Austria) made me a fantastic deal on the 9930.

The 599 and 9930 are very close in torque, the big difference is a brushless motor costs more and is initially quicker from the start, whereas the coreless is smoother from the center as it moves better for fast flying planes. I have flown coreless decades ago and prefer them to the bigger 599 brushless in jets they are more twitchy, and need a lot more expo to smooth it out. That's just my preference.

My classic Rebel is almost ready for its maiden. Maybe this the KT 142 but I had to move all 3 batteries in the nose and might even have to add a little bit of weight to balance at the beginning of the wing joiner...
CG at the beginning of the wing joiner appears to be pretty conservative. What is the consensus on the classic Rebel CG? Came out to 10.3kg dry.

Yes.
just how we balance ours here. I’ve set up around 15 now, all the same and all fly great.
Hook fingers under lip each side, just above rear of tube and lift…

I’m also running K142 with Jeti setup very close to yours. I have a 3S2100 LiFe turbine battery in the nose just in front of the nose gear, the other two batteries 2S1800 LiPo are in the tray adjacent the nose gear. I started with all three batteries up in the nose. It took several flights of moving batteries aft to finally settle on this for Cg.
