IQ-Hammer Turbines

I recently had the opportunity to visit with Stefan Schmitz in Germany regarding the IQ-Hammer line of turbines. I was surprised to learn some of the history of these engines.

Hammer engines was started by Dietmar Kramer (Turbo Diddi) over 15 years ago. His engines were originally sold by Graupner under an exclusive agreement under the brand “G-Booster�. Later the engines were sold as Evo-Jet and supplied with the Jet-tronic ECU.

Today, IQ-Hammer are available direct to the European and US markets with the following features:

-Pro-Jet ECU with all engine parameters stored on the turbine

-12V SFL12V automotive style kero igniter internally mounted

-Internal mounting for the temperature probe, starter wiring

-Only 3 connections to the turbine, 1 Kero, 1 Power and 1 communication

-High quality internal components such as Inconel combustion chamber provide and industry leading 50 hr service interval

-The turbine kit is supplied with everything you need including Li-Mg 11.1v battery FOD screen, installation materials such as tubing and filter, plus all the standard required items for operation.

-Local full US service center at http://www.vogelsang-aeroscale.com/iqhammer.html all turbines, parts and service items are stocked in the US. Virtually ALL servicing for North American customers are handled in the US and covered by a 2 year warranty.

My personal experience with the 160+ engine is it is simply the best starting, fastest accelerating, highest power/weight ratio engine I have seen. The factory thrust ratings are conservative and the 180+ turbine sets a new standard for thrust in a small package.

Interesting info... But, I have a friends G-Booster here that has been back to the factory three times and still has serious running issues. Will vogelsang take care of the problems???
He gave up and sent the engine to me to try and resolve the problem... Havent had a chance to look at it yet....

Interesting. You would think after 3 attempts there would be some resolution. Maybe there's something else happening.

Hopefully you will be able to find something when you take it apart.

We've also had a lot of problems with the Gbooster line in Dubai ( high pressure altitude and high temperature ).
Apparently the NGV is too aggressive and there is no fix for these problems on the GBoosters as per Didi's comments.
However I'd love to be able to review the latest line of engines to see if the combustion cycle has been improved.

Oli,
What problems have you had? We were flying this summer at a density altitude of roughly 6000' and the G Boosters would flame out if we accelerated to fast. As long as we were slow on the throttle stick they were fine and once up at 75% power felt the same as always. If you pushed the throttle stick hard, it would hit about 70,000rpm and just hang there until it finally flamed out. Interestingly enough, my USA AMT Pegasus was doing the same thing but wouldnt' flame out. If I accelerated hard it would hang mid throttle. Quite a few other brand engines were having problems that day as well. It was annoying with the G Booster, but as I say, as long as we were smooth and slow with the throttle they worked fine.

Its a known problem for sure. Anything over about 2000' DA here and my 130+ does the exact same thing. We also have a very high humidity here during the summer and its just a dog (thru accel) once past 75k its just as strong and fast as anything esle in its cat.., run it this time of year and its a BEAST...

Ours have been fine at that kind of altitude, we fly at 2300' altitude, when it gets hot, we'll call it maybe 3500' density altitude I suppose and no issues at all there. When we were in Cayley they were fine up until probably around 5000' density altitude, once it went over that is when the problems started, mind you, it was dry as dry can be there too, typically very dry where we fly in Princeton as well.

olnico

Yes, that's exactly the problem. At 6000' pressure altitude and/or high temperature, the combustion cycle became unstable.
Engine stall during acceleration and also at low RPM.

I'd be really interested to evaluate the new EvoJets and Hammers on that respect.

I have had the same problem here in South florida through the summer months, but have gotten around it by switching to soft throttle and slowing down my spool time. I have never had any problems at all when we have our winter months.

I guess there must be a trade-off when you stuff all that performance into a small can.

Had the same problems as Jeremy in Cayley but mine went away after a few run-ups. Maybe the ECU needed to re-calibrate to the new conditions.

you Guys talking about old stuff .....
anyone tested it with the new IQ-Line, i think not yet .....

BTW: the brandnew IQ-H170+ was released today

PaulD

Nice, wonder if mine can get upgraded while it's in for service....

great now send all new engines to oliver , have them tested and write a great revieuw for rc jets international.
i cant believe you just said all else is old stuff...?
mmm

Eagle Driver

Sandor,

as i understood pauls thread was regarded to the new IQ-Hammer Line of Turbines.

All i read in the answers was: My Booster did this and my Evo did that ...................

BTW: I visit a nice nightclub yesterday evening but i cant believe that all the girls

have DIGITECH engraved on their back side ......

Nice to just blow off customers with the "Old" stuff having issues.
Why would anyone trust the new stuff is any better if the factory cant even get the "Old" stuff working right for their current customer base? And "Old"!?!?... the G-Booster 160 my friend sent me is what.... 2 years old!? [sm=stupid.gif]
Perhaps some of you are good with flying your turbines in the winter only....[&:]

I received yesterday my new IQ-HAMMER 90+ , after some small problem in summer i send it to Turbo for inspect it , he send me one full new engine , i think have the best service , without trying to confuse things , take full responsibility if the machine's fault , or the electronics . and certainly not ours to any responsibility of damage.

Todd,

send me that Engine and i will take care of it .....
one question, where bought your friend that engine ?

jeanfi

Hello

And...what is new in this new engine ? could you tell us a little more please ?

Thank you

You covering freight? Engine has already been back to Germany 3 times and still does not work!
Engine was purchased in an airframe acquired at Florida Jets from Andreas Geitz.

Eagle Driver

Todd,

pls can you make a direct contact to the turbine owner ?

Confusing, after checking all our papers i cant find any
engine from the US that attempt the factory 3 times [&o]

But we will do our best to help your friend straight

Eagle Driver

Jean-Philippe,

the 170+ has a all new Rotor & Stator setup.

same weight and dimensions as the 160+
but better fuel efficiency.

Here is the history on the engine my friend sent me:

History:

The engine had faulty wiring on the board under the cover (a known
problem back then), XPS sent a replacement engine and my engine went
back. The replacement engine had a problem shortly after receiving it,
but I can't remember exactly what it was now. I sent the engine back
to XPS and Germany sent my original engine back to me after I was told
I was getting a "brand new" engine. The engine worked except for the
occasional high humidity "hanging" until the thermal couple went bad.
I sent the engine directly to Germany only to wait awhile for repair.
When I finally got the engine back, I had 2-3 flights before it
unexpectedly flamed-out at First in Flight Jet Rally, (first time it
ever had done that). I could not find a reason for the flame out and
had another flight the next day without a problem. I think there was
another 1-2 flights on the plane before it caught fire in flight on my
last outing before leaving for Iraq.

Will provide a serial number in the morning when I get to the office.

cant seem to find a serial number on this engine? Where should I be looking?
BTW.... this motor locked up in flight causing in-flight fire but was landed successfully.

I'll send you mine and pay the freight if you can fix it, its only 2 years old too...
