Default Whiplash with a YS .45 FR ABC RC Rear Exhaust

Any thoughts??? I'm not sure if I can swing a Jett or not.. Would this be somewhat close to it's performance?? Am I right that it would beat the OS 46??

Here are the specs from tower....

Bore: 21.8mm (.864")
Stroke: 20.0mm (.79")
Displacement: 7.45cc (.457 cu in)
Weight: 400g
Practical RPM: 2,000-18,000 rpm


Any other suggestions short of the Jett FIRE 50 that I really wanted to get instead??? Would this YS be comparable?? How much slower do you think it'd be??

Thanks!!
Deck

Oh.. I'm looking at Hitec's digital metal gear servos for this, 107in/oz torque.. Would that be sufficient for the speeds this puppy would endure??

Default Jett..

jettengineering.com

In my opinion, these are the most powerful sport engines available...Very expensive, but worth it from what I hear..

I love the YS's

What do you think a YS 45 would pull though?? 150,180, etc..??? If all conditions were perfect??? Just a ballpark figure. I'm just curious

Thanks!!

Hey guys? You there...?

OK I looked at the Jett site, is there a big difference between the 50 side exhaust with their muffler thats included for $260 and the rear exhaust thats the same price without the muffler, or a pipe?

Anybody have any experience with this beauty?

Whip Power!!!

Default YS .45 on Whiplash

If the YS can swing a 10" pitch prop, maybe an 8-10 it would give you a approx top speed of around 170mph. This is only an estimate, but using a simple prop pitch/rpm formula you can figure a speed estimate for any prop at any rpm.

(prop pitch in ft.)xrpmx60/ 5280

10" prop pitch= .833ftx18000x60/5280= 170mph

The Whiplash is extremely fast with rear exhaust motor/pipe combo's that turn in excess of 18,000 rpm's. DF or Nelson pylon motors are turning in excess of 24,000 rpm's on the ground. In the air 26,000+ rpm's. Think about it, a 35" wingspan airframe going 170+ at 18,000 and well over 200 mph at 26,000...

If you want to go fast while keeping the airframe in one piece then the Whiplash is definitely for you...

Default jett

As Dan said the whiplash is designed to take the extreme speeds without hardly any structural stress ... if the Jett is not within your budget, you can always find a nice RAM for sale very cheap these days..

seriously, even with an OS46FX you can do 150 mph easily, and thats a lot of real estate covered in a short amount of time..

Is that 150 mph in level flight or a dive?

Default 150

The 149.7 we got was coming out of a dive and flattening out for level flight. with the right prop, the 150 can be done in level flight.

Ok, thanks for the reply! I may have to get a Whiplash. If I said I wanted one tomorrow how long do you think I would have to wait for it?
