os 46 vx-df
A friend is selling his 0S 46 vx-df for a good price. Is anyone using these on a Phenom or really anything. I would probably buy a plane for it. I just did not know how they did on a prop and not a df. Just a thought.

RE: os 46 vx-df
I just got one also. I needed some help with mine and got a lot of info from freakingfast. You should read post #6 [link]http://www.rcuniverse.com/forum/m_5336135/anchors_5336135/mpage_1/key_/anchor/tm.htm#5336135[/link] Hope this will help
To get the prop to mount on the crank I reamed out the prop and used a [link]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXB958&P=7[/link] I had to cut off a 1/4" from the shank and it worked perfect.

Hello nitro junky...
According to the Tower site that "adaptor" has a 10-32 thread for securing a spinner... [sm=confused.gif]
How exactly did you use it then? Was the 1/4" you cut off the 10-32 threaded part?

RE: os 46 vx-df
yes you cut off the 10-32 end of the shank. This is why I said to get the long one! If you get the short one there is not enough of the shank left after you make your cut. If you do not have access to a lathe just put the adapter in your 3/8 dill pull the trigger back with a rubber band and use your cutting wheel on your dremel to make the cut. this will insure that your cut is straight acrossed the shank. Sorry it took so long to get back to you I just got a new laptop and have been spending alot of time getting use to Vista.

RE: os 46 vx-df
purpose made product from Tru-Turn to achieve this installation ....
for 1/4-28 shafts TT-0141-A, TT-0144-A [link=http://www.truturn.com/cgi-bin/store/agora.cgi?p_id=tt0141a&ppinc=adapt&exact_match=on]click here [/link]
6mm TT-0616-A
for 5/16 shafts TT-0519-A
3/8 TT-0374-A
10mm TT-0105-A
all shaft sizes are basically covered, and the adapters come in different lengths (more than I showed here...)
also worth considering the Fox adapter nut

RE: os 46 vx-df
Here is perhaps a dumba** question - Given the price, weight and prop conversion issues with this engine, what advantages does it have over something like a Jett 60LX FIRE engine for a speed plane?
Not dumping on the OS, just wondering why go to the trouble?
Thanks,
Mark

RE: os 46 vx-df
Someone correct me if I am wrong but the df engine will turn more rpm at the expense of a small diameter prop. The 60 LX will turn more prop but less rpm. The df engine would require a very clean airframe like a qm40 and the LX would work better on a Dust or Q500.

RE: os 46 vx-df
Id look at it that way too.
Kinda comes down to how you set up the pipe on the fan engine - and what prop is chosen. Those two variables must be matched.
The fan engine does not "have" to turn 25,000 rpm - it can, its designed to - but with the pipe set longer, maybe for 21,000 rpm - and using a 8.5x7.25 (as a start) it should match up pretty close and run nicely... while providing some useful prop
Id not try to set it up for 16,000 rpm - its just not going to work down that low due to the carb - its a real big bore. Comes down to a balance setup, as with any other engine/prop/airframe combination
Seems to me, the best people to really ask for this application is the folks that make the Phenom. Clearly, the front end of that plane is molded for using an OS 46/48 fan engine. So they know it works, and know what prop and pipe configuration works on their aircraft with the engine. (yes, and assumption, but I figure I will them the modeling professional benifit of the doubt here)

I was thinking the same thing, I e-mailed them a few day ago asking if this engine would fit. I even gave them the specs on the engine. I never did get a response back[&o] I did not know Fox fox made a 1/4-28x1/2" Long Shaft Extension. That would have been allot easer the hobbie shop I go to had the other one I used setting there so I made it work.
