I had a Webra 52 and I can't say I recommend it, even more so for a newbie.

Webras are supposed to be no-nitro engines. They also require 20% oil. I used Coolpower 15% and although everything was setup fine (temperature wise) the engine cooked itself... BTW: the engine would NOT work on Morgan FAI no-nitro fuel. It was impossible to set the needles: that's why I went for 15% nitro at CHRC recommendations.

Hard to break-in and hard to set needles! Be prepared to walk around with a screw driver in your pocket so you can adjust the idle before every flight.

25 years of engine fiddling weren't enough to cope with this %^$#@@! As it stands, although I never let the engine run lean, there were all signs of abuse because of excess nitro and lack of oil.

The main needle even flew off in flight and the replacement needle CHRC sent me was wrong, which completely busted the spray bar (which I also had to replace at my expense).

But really disgusting was the amount of fuel that leaked from the front bearing. Be prepared to do a lot of cleaning on your heli!

A Webra con-rod-broken-while-inverted later, I'm happy to say I'm an owner of a Hyper, which completely overpowers my late and defunct only-good-for-6-gallons Webra.

To me Webras are for fiddlers, not pilots.
It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

I have a friend who is using Webra 55GT-H with a Weston onepiece pipe( the minipipe designed for the West 50 engine)in a Raptor 50V2. That engine has loooots of power with that minpipe.
But it is a bit tricky to tune.
And the exhaust bolt distance is 39 mm and not 37 mm as in most other 50 size engines (OS standard), but it is same exhaust bolt distance as the West 50 engine.
This makes it difficult to find direct fitting mufflers or pipes.
I think it is only the Webra mufflers and Weston (west 50) minipipe that is a direct fit.

""with a Weston onepiece pipe( the minipipe designed for the West 50 engine""

I had 2 Weston 1 piece tuned pipes for my older OS 50, 1 pipe was smaller, at the time I had the 60B carb on my motor (still do but it's a Hyper now), the smaller pipe did not give much power, but with the smaller pipe the motor would come-on the pipe as I was spooling up and the motor would lock-in the RPM and stay on it, tuning or adjusting the curves did little to change the RPM,,,

now the larger pipe ,,,,,,,,,,,,,, I love, it gives much more power !!

my 52 was exactly the same!!!,
it only ran "pretty good" with 15% or+ nitro.

may be the 55AAR will be better and easier to operate,
i'd get one if i could get it cheaper then a Hyper.
