Hi!

Is Rossi 53 w/ Genesis throttle pipe good for Drazzle 3D (plane is 60 size and my engine is 53, I know it...)? Will there be lack of power? Should I select a smaller plane like Capiche 50 for Rossi 53?

Regards, Peter

Sorry, I ment RAZZLE 3D Not Drazzle.....

I don't believe the Rossi would have enough oomph for this airplane.

Stick it in a .40 size and make it happy.

prop it right and it will run good, razzle is light enough, we have tested our razzle with a 60sc and its good.

wessman,

I think the Rossi 53 is a definatly not the correct choice for this sort of model. I used to own one and whilst its a cracking motor with a lot of power for its size, its designed to be used with small high reving props around 10 inch size. If you try and put a prop on that'll be good for 3d you'll find that it doesn't develop the power of throttling you want. If you've already got the engine tho I'd say fit a mini pipe and see how you get on. Best of luck...

Wess, while I do agree with you that the 53 is the wrong engine for the Razzle, I've got to disagree that the engine was design for use with small high revving props. I've got both a Rossi 45 and Rossi 53. The Rossi 45 swing an APC 12.25x3.75 prop as well as my MVVS 49 and Webra 50 and the 53 swings the same prop over 800 rpm faster than the 45.

I believe that misconceptions around the Rossis stem back to an era when they were known for their racing engines. Today's Rossis (my 45 is a year old and my 53 is less than 2 months old)are excellent sport engines that are easy to tune, make great power, and have a very smooth powerband. I've used a wide range or props and they do well with both smaller diameter/higher pitch speed props as well as larger diameter/lower pitch fun-fly props.

Specifically for the Razzle though, I'd look into a 91 engine (either 2 or 4C) to get the most from the plane.

Maybe it was the engine that I had but the difference between 11x6 and a 12x6 prop was immense! The throttling was not as good on the bigger prop and on the take off roll and in vertical maneuvers with the bigger prop it just didn't feel as powerful. I even tried the motor with a 12x4 (all APC) and it was a dog! Just for a laugh, after I was told about the motor liking smaller props I put a 10x6 on and it love it! Don't recall the rpm but throttling was supurb and tick over great. Just what I found with mine thats all.

My 53 spins an APC 12x4 over 15,500 rpm. A 13x4 a little over 14,000 rpm... What kinds of rpms did you see with a 12x4?

guys - we love the rossi but and the but is only related to the razzle and again the rossi will fly the razzle well even hover but we fly our razzle now only with a saito100 or 91fx and the plane loves over power - we had to strengthen the tail but thats it -
