Delta for a jett 90?
I have jett 90 with a tuned pipe and was looking for the fastest craft to put this on. I would think a delta would be the fastest, but I can't seem to find a delta in this size. Any suggestions?
Thanks,
Alex.

A delta is not the fastest planform but if you really want one why not enlarge plans for a smaller one? The Outlaw lends itself well as does the Diamond Dust.

Regular fuse, hor and vert stabs, and a high aspect ratio wing. Look at F5D or the dynamic gliders...
Not that there are not fast deltas, but the above is more efficient.
I have Deltas too.

Look more toward some of the late 1970's pattern aircraft.
Always a great home for FIRE-90 power.
Ask around in the Classic Pattern forum - quite a few kits remain available through various sources.

Worth taking a look here too....

I think Chuck was going to make this available as a kit of some form...... eventually.

I don't really need a delta just something fast to put the engine to its proper use. Would a Dirty birdy, chaos, or an epsilon be pretty quick?

I took for granted you had a 90 and a pipe - I equated that to a FIRE configuration engine. Is that correct?
Kaos and derivatives are at bit draggy. Not too bad on speed with retracts on them though.
Epsilon is nice, but was designed for slower more modern pattern work.
DirtyBirdy is a good step up from the Kaos - but is not designed for a RE engine if that is what you have.
Bridi UFO would be a bit better.
For a side exhaust (some with potential for RE setups)
Tipo, Patricia, Curare, Brushfire, Intruder (glass version), Deception, T2A-1, Blue Angel lots around like that.
And if you are focusing on speed and looking for super-crisp pattern with it, take 6 or 8" off of the wing span.
If you have a FIRE setup, anything with an enclosed pipe setup, preferably an enclosed engine too would be fastest.
Something like an Aurora, LA-1, Arrow, Magic, Atlanta, Citation, eclipse, T2A-mkII. And the EU-1A can really move with a FIRE-90 in it.
If nothing else, there are more than a few Patriot XL aircraft out there moving quite nicely with a Jett 90 up front

What does the "FIRE" stand for? It is rear exhaust with a tuned pipe. Its the exact same engine and pipe in that slipstream plane that you posted the link to if that helps. I will look into the planes you mentioned. Which one has the cleanest look?
Thanks Bob for the help.

All of the designs are different, and each has its own appeal
The Arrow would tend to be the fastest given the right setup (just a guess based on what I remember). For side exhaust... it might be a toss up.
Most of the designs I mentioned were from the ballistic pattern era .... speed = energy = big manuvers. There was no such thing a 1:1 power or 3D like you see today. So speed was used to carry the big vertical manuvers, and make the rolling manuvers long and smooth.
