Default Webra or Rossi

I'm into the speed thingy..Wondering which way to go.Either Webra Speed 50 or Rossi 45 with the pipe that comes with it. Which engine should I go with that's user friendly and priced rite. Rossi is $139.Don't even know what the Webra cost but shouldn't be that much more.

Probably put it in a Shrike or F/20.

Any Help???
Thanx Walt

Default Webra or Rossi

Since you don't already have and engine, I wouldn't limit my search for just those two. All of the following would be stronger than either of the ones you mentioned.

Rossi 53, YS 45, Jett 50, YS 60, Rossi 61,

I realize they list for more money but you can sometimes get a killer deal. I also realize the YS 60 is a little heavier and the Rossi 61 is significantly heavier, but that can sometimes be overcome.

I have use rossi for duct fan jets and just last week bought a west 50(they say it's a webra) with prop jet.In my opinion if you want a engine with lots of power,easy to break-in,easy to tune then get the west.I didn't realize they made engines that easy to break-in and run.The rossi was a pain in the ***** to break-in and setup.

With all due respect, I also think the Webra is a fine engine. But I read your other post where you mentioned not being able to tune the West (Webra) either. I have never had any trouble breaking in or tuning a Rossi, and if I couldn't tune a Webra I would not be in a position to say that Rossis were a pain.

Seems like you have a bit of trouble tuning both engines, so you might reconsider labling the Rossi as a pain until you get that painful West (Webra) tuned. Thanks.

The west after two break in runs was able to reach and run at high rpm's and idle's just great.(now just go out and fly)The rossi would not ,they took a very long time to break-in and tune.In my opinion that's a pain when you pay that much money and still have to worry about if the engine is broke in yet or if it's going to over heat or just quit.Both are good engine's when tuned and running right but the rossi is just to much trouble to get running right.The west is just more user friendly.

What about MVVS?
They are cheap, and really powerful, many tuning pipes in accessories.

Default I can tell you from experience....

....the long pipe Rossi .45 from Chief Aircraft at $150.
will spank the heck out of the Webra Speed .50 .

The Rossi is real easy to tune....but does require some
careful breakin to reap the full benefits....they are
rated at 16,000....mine turns 18,100 on the ground,
over 20K on the pipe....a real "runner" for a hundred
and fifty bucks....

Default Rossi 45

Flyboy Dave,
You won't get any argument from me that a Rossi 45 is a great engine but it certainly won't "spank" a Webra Speed 50 that has been tuned ala West 50.

For a Rossi 45 to turn the kind of numbers you quoted it needs to be modded considerably or be turning a small pylon toothpick prop. It would be helpful if you could provide the prop & fuel that goes with those numbers. If known the Exhaust and Intake timing duration really makes the data valuable.

Oh Yea, The everyday price on a Rossi 45 at Morris Hobbies is
[B]$129

Plus the Webras are light... very light... They must produce about the lightest engines around...

This is not always a good thing of course... if an engine is too light it breaks or gets distorted more easily...
But still, Webras are a remarkable piece of mettalurgy...

As for power: both engines can be made to turn 20K. They are both sport engines, so their timings will be more or less the same. Neither of them will be very efficient at 20K without modifications...

Default The Webra is a nice motor....

....no doubt....but with the stock sport muffler, it will
never turn up like the tuned pipe Rossi....no way.

At $150., it's a solid motor.

The .45 Rossi's are still $139.95 at Morris, with the
mini-tuned pipe....same price as always. At one time,
Chief sold the tuned pipe Rossi .45's for $149.00....

....Morris wanted $179.95 for the same set-up. I didn't
ask questions....I grabbed two of the long-pipers from
Chief.

Maybe mine is a Freak....I dunno....I haven't touched
the ports (honest)....notice the pipe is slid all the way
forward....it has a black zip-tie keeping the pipe from
rubbing on the pressure nipple.

I'm running a 9 1/6-6 MAS on it....I have other props to
try....but haven't bothered with them, because of the
Super performance of the MAS. (yeah, I know....APC's
are better....right ) 5% powermaster fuel,
and still has the plug in it that it came with....a #5 or
a #6....I'd have to look.

Buy the way....my Bud just bought a new tach....we
tested his and mine on his Jett .90....

....exsactly the same reading....14.5K static, with an 11-8
APC....what Dubb recommended.

My prop is shaved and sanded...only to remove the sharp
flashing....the tips are stock....

....the prop, spinner, and back-plate recieved a Flyboy-
Dave...." three beer balance job".... ....I can only
relate my own personal experience....your mileage may
vary....

....all the Webras Speed .50's around here have sore butts.

Default uhhhh

I need a Webra-50 to try out >> "Demo"....

I dunno the fancy lingo, I fuel and fly- The Rossi-45 has tons of power (scientific I know.. )

I have a YS-45 with MACS tuned pipe that is also frightening...

And the Jett-50 (9x8, 15%) is insane in my Patriot

As usual, no real data or useful info. but the Rossi-45 (and .60 for that matter) are NOT FINICKY OR HARD TO TUNE....

My H9 tach. won't even read a ceiling fan-

Default Webra or Rossi

I've got both a Webra 50 and Rossi 45. Neither one of them is in an speed plane (the Webra is in a fun fly and the Rossi is in a sport-scale warbird, I also have a Rossi 53 which I plan on putting in a speed plane). Both are very easy to tune and break-in, and powerwise they are more or less the same with a similar sized prop. The Webra does look a bit more delicate than the Rossi though. Of all my 40 sized engine, none look as bulletproof as the Rossis (at least from the outside).

You want cheap rossi engines u can find them www.hobbyhome.net

Plus Rossi are easy to tune you just need low nitro which is less than 5% !

Cheapest that I've found for the 45 is still through Morris Hobbies. And they currently have them in stock according to their promotional e-mail.

Hi,

I've got a Rossi 40 and I've got a question about which fuel to use.

I live on the Isle of Man and it's hard to get fuel on the island (only one model shop, so many modelers) I've got 2 Cans of 10% which I'm running with my OS engines.

Can I use this 10% fuel with a Rossi, or should I wait until I can get 5% or 0%?

Any ideas?

That was going to be my next question also. I run 10% in all my engines (two and four strokes) so wil have to have a separate can for the Rossi if it won't work with the 10%. Slight problem but I can handle it.Not familiar with the Rossi but I'll learn I guess.

Happy flying

All current Rossis should be run with fuel with 5% or less nitro. You'll need to add a head shim to reduce compression if you intend to use more. They all (40-53) run perfectly on FAI (0% nitro) fuel.

Thanks for the info F2racer. I guess I'll have to wait and hunt down a can of 5% or 0%.
