Reaction 54 Jet Kit

I'm with you on that one, having the right thrust, I also have a faster jet and soon another one, I prefer the R54 to be slow, I build the R54 with idea of body boxing prop guys, I think the P60 is right for it and I want it to be slow, the P60SE has a fast spool up time, that makes it right for this jet, prop guys will have nearly instant thrust like the prop airplanes we fly, I wouldn't trust a trainee with my Boomerang XL, the engine was build about 20 years ago and it has a very slow spool up time, in order to fly it one has to be 5 to 7 seconds ahead of the engine 's rpms.

Just some advice...take it as you will.
In my experience ( have had 3 so far with various engines and hundreds of flights ), the aircraft flys best as engineered and designed ( around a smaller 54mm turbine ).
It is also a real floater. I would NOT recommend the Kingtech 80. It is heavy, too powerful and has a high residual thrust which will make landing the Reaction a challenge.

As far as max thrust and idle thrust goes, I don't think that's a big problem. I just checked the weight on the 80 and it is heavy so getting it to balance the biggest issue. I guess you got a good deal on it or you would have got an 85?

You are right on that one, I got a great deal, but the K80 is for the Turbinator.
I'm not too worry about the idle thrust, with full flaps deployed I have to bring the P60 to half throttle all the way to the runway, a bit more of residual thrust will help to bring it to the touchdown zone.

I have a Jetsmunt 100 XBL in mine and I just love it. With an 80 Oz. Dubro tank I fly for 6-1/2 minutes with enough reserve for 2 go around. Most of the time I fly at about 60% throttle, unless I want to show off - than I come low and slow over the thresh-hold and than gun the throttle, accelerate like a horny, homesick angel and pull into a vertical almost out of site
The advantage of 100N turbine is that it will work well in a scale, twin turbine bomber that I plan to build next.

Agreed, I was going to use the supplied hinges and was going to add Crow but, a friend that build one not only suggested these hinges, he send them to me all the way from South Africa, you can find these hinges at DreamWorks.
I'm using the recommend travel distance also, the flaps are super very effective, the added residual thrust from the K80 will help bring the R54 to the runway a + in this case, I think.

Actually no I'm not truthfully. I'm shocked that Dean (Helijet) chimed in and didn't make some comment about my comment saying I thought 14lbs was just right hahaha, in our jet club I'm usually the guy getting razzed for forgetting that the throttle stick does move from the full on position lol.
I love how my reaction flies on 14lbs. The last half dozen flights I had on it before the season ended I actually found myself having more fun lobbing it arond the sky at 1/2 power and doing almost floppy looking aerobatics. In fact a good portion of it I would drop my flaps to see just how slow it would fly. My JMP firebird will do over 300mph, my CAI Raptor will push over 250mph, my bobcat will rocket around at 200mph all day long etc. Unfortunately what those jets also do extremely well is devour kerosene. The Firebird is an exceptional jet to fly but boiling through nearly 2 gallons of fuel every flight gets pricey.
The reaction is something I have a bit of a hard time even considering a jet when I'm flying it. It is jet powered, but it doesn't fly like a jet, it flies like a great big ultra sport or something. The only reason really that I would consider the K70 when the PST's time comes is really that it's more than enough power in a very small and light package. I'm always sort of considering future projects for engines.
Maybe there will be a time when I get bored with the R54 and 14lbs of thrust, but reality is, it won't be the power I get bored with, it will be the airplane, so I'll put it away for a while until I feel the urge to fly it again. I have gotten bored with lots of jets over the years and sold them only to regret it a couple years later and often buy them back hahaha.

The K80 is on, next is to remove the JetCat electronics and swap them with the Xicoy ECU which is about a third the size of the JetCat one.
Gaspar said there no reset like that on the Xicoy ECUs, JetCat has a soft reset, to be used when the engine is moved from one airplane to another.

Alan, the engine mount is secured to the fuse with 4 wood screws, there is a 1/4" plywood dobler glued under the fuse during construction to secure the engine mount to, the kit is supplied with a maple wedge to provide the proper thrust angle ( 6.5° ) for level flights.

Hi Carlos,
I would not recommend wood screws as an anchor. You should use a bolt (4/40 is fine) with a nut that has a Nyloc feature. The wood screws will last a lot of flights but they are not a permanent solution.
Very best,
Alan
