Default Whiplash needs more speed

I cant say enough about this airframe. Its just AWSOME. My OS 46FX with Macs Tuned Pipe is a very good combo. But I am feeling the need to go even faster. HEHE. Was wondering if anyone is using the new OS .46VX-DF on a Whiplash?? Rick, Dan, ur thoughts?? I know alot are using the Jett 50, but I wanted to do something a little different.

Default whipped-lash

Try a K&B 7.5, or the OS50DF should give you some Rs too..

if that dont do it for you, try a JetCat P120, it may take some serious modifications however..

seriously, my next attempt will be the K&B 7.5 good engine..

Yes, the RPM's are up there, but that number is claimed using a 180mm x 180 mm prop - which is about a 7 x 7. I'm wondering if it will turn a 9 x 9 or 9 x 10, and at what RPM.

I have 5 Cyclon PC4's, which is about a .15 engine. I've only been flying one, the others are either new or have just a few runs on them. Mine turn a 7 x 4 at 28,600 using 5% Nitro. Alexander Kalymkov says she'll turn 33K with a 6.5 x 3.5. I haven't loaded it up with a high pitch prop yet - I've been researching single blade props, though, and think I'll be ordering a Bolly soon.

I'd really like to build a speedster with two of these PC4's, but might try the Cyclon 40Big in a Whiplash for kicks.

Default Cyclon 40

What's the HP rating on that motor? Maybe that would give us a clue as to the use of any high pitch props...Any info available on the motor? It sound's like the motor turns up like a Nelson QM40 motor. little tiny prop, not much useable thrust with that little prop. Let us know what you find out.

All the specs on all of the Cyclons (no "e" at the end of the name) can be found at www.cyclonengines.narod.ru

The F3D specs can be viewed at: www.cyclonengines.narod.ru/F3D.html

You have to contact Alexander to order these, and you have to arrange an International Money Transfer with his bank in Russia. Sounds scary, but it worked when I got my Cyclon PC4's. He even cut a deal because we ordered 6 engines.

Not very cheap, probably. This guy is a former World Champion in control line speed, I think. The PC4's that I have cost around $200 before the volume discount, and they're just .15's. But they are really wonderfully made.

His English is understandable in the emails that I got.

Anything from overseas takes a lot longer to get than we Americans are used to.

I do think he's very interested in making a bigger name in the US market, so that will help. He probably needs a distributor ( hint, hint).

Just looking at the K&B 7.5 DF engine and I dont think it is going to fit in the Whiplash. I think the engine is going to be too long. Rick if you have one laying around, test fit it and let me know what you think.

Thanks

Did he say anything about this being a control line engine?? does it have a throttle?? $300 bucks is a pretty good deal, since a Jett and Nelson are above that. This starts to make me wonder what the failure speed of an APC prop is!!!!

Default props

the prop listed is $30.00.
From the apc home page 26000 is all the 7.2 should do.
Didnt ask about carb but there is venturi listed in replacement part so i figure no carb.
I bet no pipe at this price either but i don t know for sure.

I'ts an F3D pylon racing engine.
Don't try to run it on anything but carbon props with continious fibers, no APC or what ever plastic props with chopped fibers.

There's a reason that he writes "Cyclon-40BiG for world expert ". These engines are not easy to handle...

That .40 engine is an F3D engine....

No throttle... just a big hole...

These engines aren't fit for every day use... they are racing engines... they need a lot of tuning and maintenance to achieve these power levels.

They break very easily (that's really not difficult at 32000 rpm!!!), parts are expensive, and when something breaks, chances are there will be a lot of damage...

They will not lug bigger props. The engines are designed to operated at around 30K rpm... lugging them down to 20K rpm will give you nothing but headaches...

Rob Metkemeijer in the Netherlands builds the top F3D engines at this moment... they cost about 500$ a pop...
Take a look at the engine breaking-in section of their web site... then you will understand what it takes to get these engines to give top performance...
The fourth time you run a new engine (first time with a pipe) it should be "4-stroking" at 26000 rpm.... , and occasionally leaned out to 31000-33000 rpm... hehe...
If fact, read through the entire web site, that way you can appreciate better what these guys have achieved "in the basement".... Because this is basically where they build them engines.

This is what you get from extracting over 2.5 kW out of a .40 engine...
