That's where mine is mounted. Under the battery tray, you could say I'm running a hotter setup.

Just don't yank on the elevator at high speeds, there is a high speed stall possibility but its pretty rare and its due to the pilot, its a fairly heavy for its size jet and needs to be flown with respect, not yanking controls like you could with a foamie.

Good post. As all jet pilots know, the wings can stall at any airspeed since a stall occurs when the wings are rotated beyond a critical angle of attack (or something like that, please correct if you know better). A lot of us also fly aerobats and nearly all of the aerobatic ARFs sold today are 3D capable and so designed to fly "on the prop," beyond the critical angle of attack. Our EDF jets (not talking thrust vectoring here) are not really designed for flight beyond the critical AOA where stalls occur and mainly fly "on the wing," correct? Anyway, good flying! Dana

Don't be worried at all about the Habu. Seriously it is an absolute sweetheart with zero bad tendencies

I'm no pro at EDF and if I can fly this jet without incident,anyone can..I love this thing!!


Thanks Guys! I was just wondering if I was over-reacting. It seems that I was. I flown many many jets, it just caught me off guard. There must be a lot of idiots out there. LOL.

And this is one problem when nice jets like this become affordable to all. Anyone that wants a je gets one. Then you see all the weird videos popping up that could be anything from builder error, wrong CG, or just plain pilot error. Just because you can hover a piece of foam is by no means a license to fly a 150 mph jet. Different set of skills needed to build and fly one of these. Not that its hard, its just different than a foam park flyer or Heli.

The fastest I've flown was my 90mm FlyFly Hawker Hunter @ 125mph. For a large 90mm foamie, thats not bad.

Habu32 ESC Cooling Trick

OK, well I had this old Jeti77Opto+ ESC and wanted to run it since I am pulling 66AMPS at full wide open on 6S. For my maiden and 2nd flight the ESC cut out during flight, wouldn't restart and forced a few quick landings.

I took the plane home and used a Dremel to cut out a rectangle in the fiberglass intake, just the same size as the heatsink for the ESC and used (micro balloons) epoxy to create an airtight thick seal. I took the plane to the field on a very hot day and made 3 flights with no cut outs at all. This worked pretty well, thank you Ron (Apollo Field) for the advice.

Here's a quick picture of where I glued the vented ESC in the fuselage. This puts it right in the air path for the intake and did the trick!

That's all I flew before the Habu DF, Foam Habus and Helis. If you have a good simulator and have a good uderstanding of flight behaviour,this jet is no problem to fly,just take it easy and learn..NOW to land it, is where the men get seperated from the boys.You just dont cut the power and float this thing in..The thing about speed is once you get use to going 140-150Mph its just seems like it's normal after a while and does'nt seem that fast anymore!!?? Does that make sense?? Next Level Please!!

hey guys
I'm only halfway done reading this thread so forgive me if I repeat someone. I noticed that it is easier to get these wheel bushings in if you remove the blade from an xacto knife in use it as an " installation tool". this way you can tap it in with a hammer.

Good idea on the controller install Lebdog.....thanks.

My Habu has been sitting in the corner finished and waiting for a replacement CC 100 HV. Decided to use one of the new CC 120HV controllers which I just received from Castle. I figured the little bit of weight difference between the 100 and the 120 would not be a big deal in the HAbu and I surely would not need to worry about over taxing the controller. I will be installing the controller under the battery tray. So my Habu maiden will be this coming week.

These bushings have come-up lots of times before..I sanded the inside of the wheel-hub until the bushing just presses in with no effort.if you notice,the plastic bushing spins great on the spindle,when the bushing gets pressed into the wheel,the wheel don't turn and modeller's like to drill out the center of the plastic bushing.Try sanding the wheel hub...no drilling required.

I flew mine today for the first time with Tams struts installed and what a difference they make The airplane handles so much better in the grass its not even funny. I drilled my bushings out with a 5/32 bit(drill press) and then pressed in a piece of brass tubing that fit the axles perfect. Now I have a half decent bushing that run really smooth. Im probably going to buy Tams wheels eventually but will see how these hold up. Batteries seem to be breaking in as well cause it seems to be hauling the mail now Overall I couldnt be happier with this jet! It really is so much fun to fly
