Upgrading the gear later would be easy. The stock fixed gear are the eflite retracts without the jackscrew and electronics. As to the second bec I had to use the outboard bec. I have a v1 eflite 80 amp esc which has a bad bec in it. The cc bec is rated at 10 amps v 5 on the on board bec. The voltage is also adjustable. Finally if the esc burns up there is a chance that the external bec will give me control power. It only costs $20 and it is some peace of mind.

A note on the v1 Eflite Pro 80. On my six flight the throttle "snuffed out" like a thermal lockout. But I have checked the ESC, and it does not run hotter than 150-170 deg F. So I sent back and got a v2. Since then I have had no issues.

So they say the v1 was just a BEC issue, but I am not so sure. I would not recommend using a v1 Eflite Pro ESC, and the replacement is free if you ship it to Horizon.

PS I am not using the BEC on the ESC, so that is not what caused the throttle cut out.

Tony it is a free replacement if you have a receipt. I bought the Habu as a package from someone off of RCU. No receipts. My throttle never waivered just the servos. See you at the BOX tonight? Ross

Hi all Habu 32 people. I am considering getting this jet, using the flaps and eflite retracts. I have a Futaba 7cap radio with a 7ch fasst receiver. I would basically have to Y everything together except for the rudder/steering (I could use the 7th ch).

Would I run into any issues using a Y harness on basically all the control surfaces, flaps, and retracts? May seem like a silly question to some, but I've alway simply used 4ch's for all my previous planes...

Thanks

No Problem! I would split the ailerons so you can program in a little crow with full flaps. It makes a big difference on landing speed.

Never fly an A model anything!

If you build the 32 absolutely standard, your TX and RX will be fine. It will even land ok in the stock lightweight configuration. Add any weight though for a faster set up and you will need to consider the crow settings. It is cleverly designed to not need reversed servos or high level programming as a stock build.

That's probably how I'd build it, stock fan and motor with eflite retracts. Looks like stock it'll still do 120+, which is plenty for where I fly at.

No way. Split rudder and steering servo. It's a much easier setup. Crow is nice but def not needed.

I think that with the very affordable price of this jet, there are going to be quite a few of us (myself included), who have never had such a fast, high quality, and high performance jet. There are bound to be a LOT of questions that most of these guys would normally take for granted. They may be shaking their heads with how basic some of our questions are. I hope they remain patient with us!

Not that our skills of piloting are insufficient, but building for these speeds becomes much more critical; and these nuances of construction are very new to us. For example, when the manual suggests using epoxy, with a jet like this I start to question whether the hardware store epoxy that I've used on so many aircraft will be completely sufficient, or if I should be going for something put out by modelling companies, such as BVM. And I hear the mention of Hysol, well, I've never heard of such a product before, and I understand that some are using it on the control horns, but is it greatly superior to epoxy, or is epoxy just as good? Is Hysol suitable for spars, etc, and other high-stress, critical structural components, etc.

I have Z-Poxy PT-39 30 minute epoxy. Is that good for all of the epoxy requests in the manual, or should I look into these other adhesives? Should I go for thixotropic or not (a la BVM). So may questions!

I have used Hysol on one of my Habu's and regular 5 minute on the other 2.

I think regular epoxy is fine for the control horns, just make sure you sand the horn down a little. I cleaned mine with alcohol before I sand the horn, just to remove any mold release. I stuffed my first Habu and high speed into a metal fence, it probably hit at close to 100mph. The control horns on the stab ripped out taking a bunch of the wood with it. The rest of the horns stayed in place.

Don't over think this little jet, yes we must take care during construction but it's pretty straight forward in it's build.

Don't know if it's been posted but Wemotec are going to release a 80mm Midi fan.

Fellas - working on the wing spar installation right now....I just took the fuse our of the packaging, my jaw dropped on the quality of the paint and glasswork! Regardless, I can't believe that only the pinch of the two Allen bolts is all that holds the wing spar into position! Crazy!
