Anyone have plans for bulilt up jet for p-60
I am looking for plans for a built up sport or scale jet for my p-60. Let me know if you know of any, there seems to be a shortage of jets for this size engine

The Jetmach Sport 60 will be easier to build and a P-60 is a good fit for it, you will be able to have at least 8 min flights and becauae of its size the wing loading will be light.
With the 44, both LDS or Nick's, by installing a P-60 you will have fuel for 4 min and the wing loading will go up.
My Boomerang is 32 lbs dry, it gets off the ground at 42 Lbs and it lands at around 36 lbs, I have 28 lbs of trust, more than enough to have fun flying.
A P-60 is going to fly my Reaction, more than enough .

Just got the Turbinator 2 from Boomerang jets. I've only had time to unpack the box to make sure everything is there and OK, but this is a *really* impressive kit!
It looks great, the covering is nice, the landing gear is electric and all trailing link, nose wheel steering is direct drive - and its got cool fiberglass tip tanks.
You could not build a plane like this for $999 plus shipping...

This thread is pretty old, so I'm not sure if anyone is still monitoring it. I recently picked up the Boomerang ARF Turbinator 2, and after gluing on the fin and hinging the rudder I noticed that the fin had a pretty significant twist to it. After an email exchange with Larry Roper, he sent out a replacement fin and rudder, but amazingly it has exactly the same twist. I'm curious now if they are all that way, and perhaps they fly fine with the twist, or if this is a defect that I need to figure out how to fix. Does anyone else have the Boomerang ARF Turbinator 2, and can maybe report how true their fin/rudder alignment is? This is my first jet, and I'm really trying to minimize the number of potential surprises on the maiden.

There is a way how to fix flying surfaces that are twisted.
I'm planimg to build a 85% Reaction for my P60 this summer, it should have enough thrust for almost unlimited vertical climbs.
I've been looking for a jet small enough but, I don't like what I've seen.

Hi Bob,
Here's a couple of pictures. In the upper image I have the rudder loosely attached with the hinges, and I am holding it such that the top of the rudder is aligned with the top of the fin. In the second, I have the fin sitting on a cutting board with the root of the fin aligned with the vertical lines on the board, but the top of the fin is clearly misaligned. Doing some rough trig calculations based on the photo, it seems to be about 4 degrees of twist. I can trim the rudder so that it is aligned with the fuselage centerline, but then the top of the rudder and the top of the fin are pretty far off - about 3mm at the trailing edge. Since the fin is adding some left yaw, most likely the rudder will need to be trimmed right pretty far, and I guess the concern is that the appropriate trim might be speed sensitive.
In my experience most ARF aircraft are built with jigs, and since I have two fins (the one that shipped with the kit and the spare that Larry sent me) and they are both identically twisted, I'm thinking perhaps that the jig has the twist built in. If that's the case, then perhaps there are other T2s out there already flying that have the same twist, and if they fly fine then I'll just go with it. Otherwise I'll start thinking about how to remove the twist.Since the full fin is sheeted, it seems that this will involve removing the covering and sheeting, straightening out the skeleton, then re-sheeting and recovering it. Not looking forward to that.

EDIT: sorry - just joined RCUniverse, and I apparently don't have enough posts yet to include photos!? I' guess I'll post a few more here until it lets me.
