Check out the new F-84F Thunderstreak at K & A Models, its designed for a 480 or 609 fan. See it at www.kamodels.com.

Just more shameless promotion of K & A Models and the Albuquerque area.

If I may quote Eric Cartman from Southpark,....."Sweeet". Man I love the swept wing version. Dangit, wish it was larger for 90mm but I guess I could finagle some retracts into it...assuming I ever get time to build one. My little K&A Sabre is still in the box after 2 years!

Very nice!

Oh and you might want to change the title to include the company name K&A, that'll help when people use the search function.

Thanks for the posting of the F-84 Kyle.

Just to let some of you know we have not yet installed a set of retreacts however we did design the plane so that you can.
We ran the wing thicker at the tip so that at the point where the retracts will go you have about a 1" profile. This is good for most small retracts such as the spring air and robart's to be installed. We will try our best to get around to installing a set so that we can pass on the photo's and info to those that are interested. Most likely one of our customers will get to it before we do but we will try.

Best regards,
Ken Williams

Very nice F-84, I used to pass one everyday going from work to night classes many years back. It is still where it was before on a pedestal outside of a VFW in South Houston near the Ellington Field. Congrats on the new offering.

Ed,

I tried to change the heading but it only changed within the post. If you know the secret please let me know.

Well won't say for sure but when it comes to EDF's you have to stick within certain percentages to arrive with a plane that performs well. Unless your flying turbines keeping the inlet or exhaust scale is out of the question. That is if you want your plane to perform well. Just the nature of EDF's.

Hi Ken

so you don't give straight answers?
"Unless your flying turbines keeping the inlet or exhaust scale is out of the question" ?
Could you explain.

Have fun with fans

Very nice model!

True statement Ken and it has always been my way of doing things.

Klaus with a 'K'. Turbine model engines actually have a very small FSA compared to what we try to do with EDF and ICDFs (thrust wise). So what Ken is saying, that some sacrifies will need to be made in most scale models to achieve the desired performance level with EDFs.

Hi Klaus,

Most EDF's require an inlet swept area of around 115 to sometimes 140 percent to perform well. In most cases you can not keep your inlet scale on most EDF jets an achieve these numbers. Most of this applies to smaller EDF's in the mini 480 size. As your plane gets larger you will have less of a problem arriving at these numbers.
The upside of a tubine is that you can compress the air much easier then with an electric motor thus being able to keep the inlets scale.
