GP Reactor 46
 

Hi,

I know it's discontinued but the GP Reactor 46 has been my favorite cheap hack for the longest time. I know the plane quite well so when the opportunity came to flying at a demo meet in February, I decided to resurrect my landing gear-less old model with a new fuse & tailset. I was flying the old one with an OS Fs91. So couple of questions-

Though the Fs91 has plenty of pullout, the Fs110a I have has much more power. In the last season I was hovering a 3.7kg airplane with the 110 with good pullout.Crucially, it's lighter than the 91. The Reactor is lighter too. Should I use the 110 on it?

Secondly, I wanted more positive connections on the new reactor, so I used ball links both sides on Sullivan full-thread 2-56 SS pushrods. But someone told me those are prone to snapping. Is that correct?

I would use the lighter, more powerful engine.

I would not use ball links on anything but a throttle and sometimes not on that either. Unless you are meaning the swivel type ball link.

I have a Reactor also. I am using the Saito 82 and it lacks power for hovering. But even worst than that - I find the plane really difficult to hover. I am probably missing some key point, but this plane also does not want to take off of the runway! So I wonder if you have to make some adjustment to the thrust angle or to the wing incidence? I moved my thrust angle up a little and it seemed to help.

That's quite surprising. My much repaired reactor would still hover. When it had the LG & I could do ground takeoffs, I never used full power even with the 55. I had no modifications at all.

My new airplane is nose heavy. Rather than add dead weight, I will put in 4.40 pushrods for the tail. Will test with the 91 pm Saturday. If not happy, putting in the 110 is easy because dimensions ate the same

I too have a Reactor that is all beat up, I guess I built it light since it climbed like a rocket with a Magnum .52 2 stroke. I have since converted it to electric, glow fuel soaked the hatch to a point where I was not able to recover the ever peeling off covering. I ended up buying a new hatch and now I fly it with a Tacon 46 motor, that is plenty of power on vertical lines although flights are limited to 6 1/2 minutes. I have to agree this plane does not hover too well.
