Too Much?
 

Will a Ram 750F be too much engine for an AV8R kit?

I'm thinking bigger turbine because we have a shorter grass strip.
Plus Im negotiating to buy a second hand Ram now.

1200 kit or the 2300???

RE: Too Much?
 

Is there an 2300 AV8R-kit?

RE: Too Much?
 

Are you thinking Facet?

I didnt know the AV8R came in 2 sizes?

RE: Too Much?
 

Sorry, was thinking Facet, duh [X(].... Dont think you can use 750 on the AV8R, not designed for that much weight or thrust back there.... The DV8R was designed for just this very reason...

RE: Too Much?
 

Yeah Im thinking the weight will be an issue as well

RE: Too Much?
 

so who wants to sell me a good running 12# thrust turbine for $1100?
anyone?

RE: Too Much?
 

Shok,

The 750 is too large and too heavy for the AV8R. We do NOT have a larger AV8R but we are nearing the release of the DV8R (see Below). This model is much larger than the AV8R and designed specifically for the 18 to 28 pound class turbines. Wingspan - 88 inches length - 94 inches with an all up weight of about 22 pounds. Full retracts all around designed specifically for this model. There will be full details on our site (www.flypcm.com) in just a few weeks.
The models (AV8R and DV8R) are shown in the diagram at scale relative size to give you an idea as to the DV8Rs mass.

Hi Pat

Is the DV8R expected to have the slow flight / short field performance of say a Boomerang or even the KingCat?
I have a Simjet 2300 (25 pound) on the way, but only have a short field near.
Thanks,
Edgar

RE: Too Much?
 

Yeah looks good, short field grass is a must for me, so Im pretty limited on options.

Shok,
With the AV8R and a 12 pounder, you can get on and off 250 feet of grass, Trust me! :D

Yeah I defiantly want an AV8R, just short on funds for a new 12# turbine :(

RE: Too Much?
 

Hmmmmmm,
The Dv8r sure looks a lot like a CJM TALON

I also talked to Bruce Tharp at the SW AMA show about his Reaction 54.

I liked it alot but I'm not thrilled with the engine position. Plus man that is a huge plane. The wing cord is huge.

He had a Ram 500 on his, I asked about a 17# engine and he really didn't want to hear that. He said a 12# engine was more then enough.

I think a 17# engine would be right at home in that thing.

Edgar,

Depending on the power you choose the DV8R will have a very short grass field take off capability, after all it really boils down to weight v thrust and lift. I hope to be done with my prototype within two weeks and I will let you know it flight envelope then. I expect to have parity with those other models in slow flight and take off distances.

As far as the DV8R looking like that other model, I guess that is true in as much as an F - 18 looks like an F - 14 to the uneducated due to the twin tail design. It is a little like suggesting that the Airbus looks mysteriously like a Boeing. Of course it does because there intended purposes are the same. But the DV8R was drawn by me as an extension and refinement of my AV8R almost a year and a half ago - I had not seen that other model. Also if you look at a three view of both you would have a much better chance to see how different they are. My AV8R was drawn as a twin tail over 3 years ago now and has proven a good way to put the engine where it is . If you think about it for more that a few seconds there are only so many ways to put a jet blast of 650 degrees or so down the centerline of a model. There is a reason most sport jets follow just a few current examples. Also should you ever see the two together you will see quite a bit of difference in many aspects.

RE: Too Much?
 

Pat I would be interested in knowing if the DV8R with an 18 pound turbine (KJ66) would handle approximately like my AV8R with the Wren 12 pounder?

Please let me know when the flight testing is done and you are ready to sell kits.

I like the looks of the DV 8R but I don't care for having the stabs hang below the fuselage. It looksreat but one gear up landing the the tail or stabs will rip right off. Do you need the anheadral?
