A couple of ARF ideas......
 

As opposed to just a few short years ago we have a wide variety of ARFs available to buy. But.........giveme an inch and i'll take a mile!

Ireally think a P60 sized F15 would sell like hot cakes. Wasn't someone working on one? I would also think therecould bea market for a small F18c ARF.

What does everyone think about a P60 sized F-15 / F-18?

RE: A couple of ARF ideas......
 

I think it would be really tiny to fly correctly on a P 60. The one your talking off was a prototype from Skymaster /Airpower, it was really nice saw it at jetpower maybe 2 years ago, it is a shame that they did'nt push the design further but I hear that it was too heavy. I think that small planes should stick with single exhaust, bifurcated pipes eats too much power but there is for sure a market for small ARfs. I would love a small eurosport

RE: A couple of ARF ideas......
 

Good point on the bi-furcated exhaust. The yellow F-18 single has flown successfly many times on P-60.
Unfortunately, Yellow doesn't make an ARFof it anymore, but if that 18 can work, surely an F-15 of the same size could work. I think the wingspan was like 46" or something length of 60 ish. Not really tiny. My tam 1/12th is tiny!

I had a nitro ducted fan F-15 (top gun) for my first jet. Ithink that size would be perfect but I'm pretty sure they went out of business.

Why the P-60?

Why not the MW44 Gold?

Smitty,

Which Tam model would that be? Span? Weight? Wing area?

I've heard of several folks planning single-turbine models of twin-centerline thrust airplanes (e.g. F-15, F-18) by aligning the turbine with one outlet and using a traditional single pipe.

Apparently the asymmetry in yaw is small and almost not noticable. An Air Force test pilot friend who has done a lot of engine-out work in similarly configured full-scale AF planes says you don't even need to step on the rudder.

You'd just plan the equipment install to laterally balance and it should work. Would make smaller planes like the ones discussed here more viable.

I would love one. I think it could prob. be built light and come in around 15-16lbs dry. Also, I know it would mess up the scale app. a bit, but if you made the outside of the F-15 rear thrust tube to look like twin nozzles, but in fact both are open up to look like a figure 8 layed on it's side, but have the x cut out, you could mount the turbine in the rear, skip the tube and plan to install equipment forward. This would save weight as well.
If you ever seen the small HET f-18 electric jets, you know what I am talking about on the rear exhaust outlets.

RE: A couple of ARF ideas......
 

That would definately work. But, if you wanted to maintain a semi-scale I'm sure the pipe is not a big deal. Like Isaid, there are many Yellow F-18's flying on P-60/70 with a bi-pipe. The F-15 nozzles wouldn't be anymore difficult. I wonder if anyone has an old un-built Top Gun F-15 that was made for tractor fan? (OS 91/Dynamax?)

Just found this from Sid Gates:

My conversion is single dual wall tail pipe.
