Right now I have 3 ahead of that.

On my table right now is a:

P-38 30"ws
A-5 vigilante 31" ws
Mig-21 57"ws

Emailed Cedarhobbies.net to have them put me on the list for the B-52 80+ inch w.s. with 8 ducted fans, that they are coming out with. Will have to save a lot of coins for that one. Uses 8 ducted fans!!!!

Just like them.
Use to build the F-15D&E model for McDonnell-Douglas
and the T-45Goshawk.
Also worked on the Navy's T-40 trainer which were used to train F-14 pilots and wizzo's. Use to be a Model 40 Sabreliner personal jet.

Default Flew and was under powered.

Flew F-15 today with good weather and fresh pack.

Fly's but under powered. Need to go 4S or put bigger prop. If I build this again it will be pusher. To much stuff in the way to get good airflow with mid mounted prop. Am severly limited in sizeof prop by the side structure. Trying to figure out how to cut sides out and still retain it structural strength. When I get it up on speed it will be a great flyer. Just posted for reference if someone try's to build one.

What's the weight on that one? I fly a SU27 profile with a 24" wingspan on a CSRC 2s 800 and a J250 on a 4x2.5. It only weighs 10oz... don't get me wrong, it could use a little more power, but it's decent for just flying around. Rolls like a drill, loops like, well, what's something that can just barely loop if you do it right?

If you can go 5.5x4.5 or a 6x4 you'll get a bit more thrust out of it, that might be just enough. Also check that your CG and thrust angle is correct. I can't imagine you would need 4s! Adds weight too!

(Sorry for all the suggestions, I just maidened a 28" full fuse F-15 and it was overweight, nose heavy, too much downthrust, and too much elevator throw... it was an adventure, I'll say that...) but I was using a 1550kv motor and a 6x5.5, you should get pretty decent thrust out of that 2000kv motor right?

Mine is close to 16 oz with changes. My biggest problem is that the battery and equipment is blocking good airflow to the prop and can't go up in prop size do to the location of motor. If I build this again I will make it a pusher with motor on the tail.
