I'm in the Market for a ARF ducted fan model. The design I really like is the F22 Hornet, but an F18c is also on the list. I have looked at the Yellow Aircraft F22, but haven't found a price. Don't know if it's ARF either.

Does anyone have ARF kit recommendations on something for a .91 2c DF? I was thinking this may even be slightly underpowered for that specific model. Anyone have ideas on attained speeds on a setup like this? Can't go the turbine route yet, just too much money for me, so trying to find a speed performing DF arf.

Yellow Aircraft has a few Hand built ARF's for 91 DF (very nice Highly detailed). You cant go wrong with the Starfire, The F-16 or the F-18. The YF22 is not out yet. Call Shaun Evans to find out what is in stock. 619-944-7574

ARF's for DF power are quite limited. Yellow has some that are top notch but they are pricey.
I'm afraid those are the only kits I know of that are ARF, plus the Hawks off Ebay.

There are still some good DF kits out there though, if you don' mind building a bit.

BTW, the Yellow F-18 Hornet single is a great model, however the F-22 does not exist, yet?Perhaps in the future for jet power.

There was a Yellow Starfire for sale here on RCU for $2K. That's a gret way to start and it is a FAST SOB.

Good luck!

If you are really "mad" on the F-22 and want it ARF and ducted fan powered, the only one I know to exist is the Christen Diffusion F-22. It may be purchased as a kit or fully built and it was specifically designed for Ramtec/O.S. 91 DF engine power combo. Today also exist a turbine version and I remember reading a few threads on it here on RCU.

I add links to its USA distributor as well to the original French manufacturer web site:

Anyway be ready for important prices, nothing to do with propeller driven ARFs. Regarding the F-18, and as stated previously, the only one available is that from Yellow Aircraft (available on order only, as far as I know). Then, you have a full composite one from Germany originally designed for twin EDF propulsion and it should be your task to modify it to glow DF, something not recomended if totally new to ducted fans:

Hope to have been of some help.

Thanks fellas for the info. Did not know about that French company listed above carrying the F22.

I have been flying pusher aerobatic jets (.76-.91 2c) and am making the transition to a DF now. I would like to go all out for performance on the next kit being this one. No one at the local field flys DF's that I know of this size, and we mostly fly privately. Curious as to the capable performance of the .91 DF combos in these birds...I imagine they are relatively close in speeds against their pusher jet cousins, but I was really looking for a step up in speed. Am I going to think something like an F-22 w/ .91 DF is sluggish against the lightweight aero pushers I'm used to? Or are these quite capable of 160mph+? Like I said turbines are where it's at and I know, just can't afford those dang things.

Somebody needs to make a cheap turbine and quite selling these things on the "ooh ahh" factor. (I just can't see the parts design layed out on a table being of any worth near what they bring in)

Hmm, sorry to ask again, but can anyone answer this?

Dude if you are looking for speed an F-22 wwill not cut it, wayy to draggy.

If you want speedm go for a Yellow Starfire, Dynamax Fan, OS .91 and a JMP II pipe. That's about as fast as you will find nowadays, unless you are lucky enough to find a BVM Agressor or a BVM Viper.

Some pusher models are pretty fast. A Ducted Fan F-15, F-16, F-18 will probably be just a little bit faster if at all., however they are wayy cool to fly.

Go get a Starfire.

Your best bet is to buy an already built DF jet second hand. There are several in the classified section.

As FalconWings has correctly explained, scale ducted fans are not really speedy models due designers looked for presence and scale look more than speed performance and they tended to be quite draggy for high speeds. Furthermore, the speed range you are looking for is even out of scale for many models: this is, if you consider the linear scale speed efect (and there are various theories regarding this), 160 mph+ for a 1:10 scale ducted fan model (that was the most popular scale), that gives a real plane flying at 1600 mph+, and for sure few combat jet aircraft are able of that speed at low level.

If you are looking for top speed, then sport planes are your target; and even then, be ready for dissapoitment as as far as I remember, the top speed measured to ducted fans were between 180 and 200 mph, and those, of course, were top notch sport competion models.

The Yellow Starfire has been clocked at 219+ MPH. Is that what you are looking for? It will get the job done and it slows down nice.
