Model Forum / Radio Controlled / Air Models / November 2006Behotec turbines
Hello all, I have a Behotec J66 turbine, which has suffered a crash that has destroyed all of the electronics, i.e. the ecu, both gas & fuel valves, the IO expansion boards etc, everything that makes it function. Apart from a few superficial dents, the turbine seems to have survived, with no ingestation, & turns smoothly. My question to this NG is; where can i buy all the elecronics from ? Or get it checked out & /or does someone service these turbines. Yes i have checked out the Behotec website, English & German versions, but it's less than helpfull. So, I'm looking for someone in the UK that can help. Could the electronics from, say, a Jetcat P80, be programmed to make it work ? I know someone here can help. Cheers for now. Ray It is quite hard to totally destroy a piece of electronics by impact damage. Even if the circuit board is broken into several pieces it can often be repaired. Similarly, components can often be replaced as long as they can be identified. The biggest problem could be that the microcontroller is physically broken and though that can be replaced, the firmware on it can't. Depends how much effort or cost you are prepared to put into it Allan > Hello all, I have a Behotec J66 turbine, which has suffered a crash that > has destroyed all of the electronics, i.e. the ecu, both gas & fuel [quoted text clipped - 7 lines] > say, a Jetcat P80, be programmed to make it work ?

I would never trust a cracked board in something with such potential for third party damage. I think if we go down the road of potential damage again we will end up back where we were before; for example, that the drive to and from the flying field makes everything else pale into insignificance. Not that that can be any justification for not getting a proper repair made. Or a proper build of the plane, training of the pilot, proof of no interference etc etc Anyway, just what is the state of damage to the ECU?

I wouldn't trust a cracked PCB in my ABS either, and I would sue any garage who fixed it by bodging. >> It is quite hard to totally destroy a piece of electronics by impact >> damage.

Any repair can be either a bodge or a proper repair. As I said, depends on the effort or cost you are prepared to put into it... Allan Ray Do not even attempt to repair these circuit boards.

Yeah I e-mailed Mike, he just put me onto the Behotec website, German version. I'll see him at LM tomorrow. Cheers Ray > Ray Do not even attempt to repair these circuit boards.

The ECU is not actually phisically broken, nor is the I/O expansion board, but they dont work, when i plug it all together, the GSUscreen lights up momenteraly then goes out again. So I have spoken to a guy in Sweden who is right up there with Behotec in Germany & he is ordering me the electronics, ECU & IO board + the two valves. It's gonna cost a few quid, no a lot of quids , But it will be ok. Cheers. Ray > Yeah I e-mailed Mike, he just put me onto the Behotec website, German > version. I'll see him at LM tomorrow.

I just bought a new jetcat P120 as a first turbine for me to put in a Boomerang XL. > The ECU is not actually phisically broken, nor is the I/O expansion board, > but they dont work, when i plug it all together, the GSUscreen lights up [quoted text clipped - 43 lines] >>> Paying users do not have this message in their emails. >>> Try SPAMfighter for free now! Hiya Timelord, the P120 & the Boomer XL are as far as i can tell, a perfect match. But I suppose SOMEONE will have other ideas of course. The Behotec I have, is equivelant to a Jet Cat P80, with around 20lbs of thrust. The difference being that if you have problems with your P120, help is at hand almost immediately, from several, well informed sources both UK & all over the rest of the world. Whereas, with Behotec, a reply from the factory may take several days, at least, & then it will usually be "send it to us". There is, at present no UK representative for Behotec, but i am in touch with the Swedish rep, who is very helpful & speaks perfect English. I am ordering my electronics through him. If I were in the market for another Jet engine i would not hesitate in buying another Jet Cat, as the P70 i am currently operating in my Baby Boomerang, is faultless. Cheers for now.
