Default Great Planes Reactor GP/EP!!

Here's some quick shots. The out of box component weight was about:
1335 grams = 47.67oz. Going with the recommended 42-60-480,CC80, 6s2p setup. Kind of like the bottom scheme. It'll be easy to tell which side is which instead of the monotone scheme on the "Mini" Reactor. Super job Tower! Keep em comin'! Back to the saltmines....

More shots of the firewall and battery compartment. They even coated the firewall with epoxy for the glow guys.

Plenty of room to swing an 18" prop it looks like. About 10-1/2" to center of motor mount.

Default Reactor

Will be following this on closely. Picked up my reactor today. I have a eflite 60 and a jeti 77 opto for this one. Seems like a well built plane.

If it flies as nice as the mini, you will love it.

I'm thinking about the Axi 4120 for this one. Goodluck on the maiden. I'm not sold on the Rimfires yet so I'm curious to see how it works out for you.

Axi will be a lot heavier than the Rimfire, so hopefully you'll have more HP and swing a larger prop. I have my doubts as to whether a 15 x 8 will be enough for 3D work and hovering on the 42-60-480. The watts are there, just need a larger prop probably. We shall see...good luck with your install and we'll look for your results too.

Some quick shots. Nice work GP! Love the color scheme. Now for the fun part-flight testing!

Flybri and Varble4U, I'm using DS821's all round and a HS5625MG for the rudder. Not messing around anymore. All carbon pushrods, Robart hinges, ball beaing horns and titaniun pushrod tips. Plan on some serious G-loads! Don't know how she flies yet but if it flies like my Reactor Jr. I'm already in luv. With the fronts moving thru it will probably be next week before I can maiden. Plan on some video though....

Did the full size servos for the elevators fit back to back ? The fuse at the mounting area does not seem thick enough for two full size servos.
Thanks , Ken
I think the idea about the carbon rods are a good one.

The servos fit with a little blade work to the servo holes and there is just enough clearance for larger servos width wise. Doesn't look like it but they do fit. The carbon rods are a must on my latest 3D birds. And I haven't heard of anyone crashing a plane lately by overdoing it in the servo torque department. The recommended servos probably will work fine, but I don't like blowback due to marginal torque and in this case-more is better! My AUW came out to 6.2lbs, thats about 1lb lighter than my Showtime 50. More squares on the wing too, so it should slow down well. Damn weather, quit raining! There are people trying to maiden planes here, how bout a nice bluebird day? Looks like Tues or so will be the day according to the weather quessers.

I picked up some carbon rods from the kite store, and still have some titaniumn ends from my heli builds. Measuring to see if i can get my full size servos in. I went with the Klett tail gear, comes in yellow plastic. I still am waiting for my motor mount spacers, to mount my eflite 60. Hope to hear some maiden flight reviews. I had bought the Hitec 225's to fit in the cut outs but may put in the 821's also

I'll probably get flack for overbuilding, but I went with stock hardware on one of my last birds and regretted it. Nearly cost me the airframe, I got lucky and only had minor damage. Sorry but I like to keep em flyin' as long as possible and that's one area I wont have to worry about. Hey, if you fly helis, then I don't have to talk to you about proper linkages! Saw one go in a few weeks back with some control/linkage problem. Hope you have a great holiday season!

Hey EDFrules. Wich of the 2 planes do you like the best. This Reactor or the Showtime 50. I am going to be getting somthing in the .46 size for my evolution .52 engine. Going to stay with glow to save money cause I may get the new Spektrum 7 also. I just realized that my other radio has all the models used. I need more model memory lol.

Still haven't maidened the Reactor yet. Had to work today, and it was perfect flying weather, I could just scream . But got home too late to get to the field and set up, so I flew my E-foamies Yak next to my house. Not as thrilling, but hucking nonetheless! Will give a detailed flight report when I do. Having said that the Showtime appears to be a great precision aerobatic flyer, it will hold a line with not much coupling. Landings are real straightforward. I've got a nasty schedule coming up so I'll try my darndest to get the Reactor airborne. Typical story, planes ready, weather /work schedule don't coincide! Get the DX-7 for sure, no glitching,no frequency issues and faster response ta' boot. Can't go wrong.

OK you talked me into..... I picked up the Dx7 last nigth and went ahead and got the Showtime 50. I wish I could go electric in this plane but I have the evolution 52 to put in it. besides I can fly all my other electics and fly this one while charging the batts to fly my electics somemore

Now you need to get the Reactor too! Got 7 flights in today and what a plane! This plane will blow you away with the tumbling antics. Does an all axis tumble like the little one(Reactor Furball?). Landings and takeoffs are a no brainer. Very precision on low rates, click to high rates and let the 3D begin! Harriers are a thing of beauty, upright and inverted. Will snap big time. Walls are box square! Ka-pow, straight up! Everything about this plane is smooth. No structural or mechanical issues to report. Cowl screws worked loose a little, that's about it. If you're planning a .70 sized electric 3D ship, this one's for you.

Default Reactor goes to the Dark Side...

Thought about upgrading the Reactor power plant and decided to try a Neu 1509/2.5D with 6.7 to 1 gearbox. Dropped down to 5s2p and went up to a 17 x 10 prop. Pulls about 66 amps @ 1050 watts static. About 204oz. of thrust. Gives the Reactor a 2:1 thrust to weight now. Big time difference. Serious power, almost too much...nah! No throttle lag compared to outrunner. Takes off about 1/4 throttle. Got motor mount from Espritmodel.com. And thanks to Steve at Diversity Model Aircraft for running some numbers on P-calc for me to confirm motor choice. Sometimes it's good to have a professional opinion before dumping some more money into our models! Noticed covering a little loose in spots after last flights, looks like some torquing of the airframe may have been going on. Now that's what I call fun!
