There are many choices. I sell a 500T that will enable you to fly light with huge thrust on 7x5 prop. You'll be able to fly slow and pull back increase throttle and increase speed as you fly on 3S2P with only a 40 amp ESC and dual 2200 LiPos.

thanks for the super fast reply i added your store to my favorites , looks i found my xmas gift

I liked the 500T on my TJ... It did well on 4s with a 6x6.5e props.

TwinJet JustGoFly 500T 4s (5 min 41 sec)

Hey Tas, You're well over 100 mph and heavier than can be configured for 80-90 flat, and faster in a dive. My first TJ ran a 500T on 3S, dual 2200. I imagine with better batteries now you could run dual 1500's. This keeps it light and light can be flown slower, with immediate jump to high speed and 7" props give huge thrust. This is the setup I think lasts the longest since you can pull the nose up and pound the throttle to get out of trouble. We have TJ's flying for four years on this configuration. 6.5x6.5 is enough to get over 100 mph. Here is an old video of me and a buddy flying:

Tas - you are a speed demon. I love speed, but sometimes you just want a great flying setup with ability to increase speed when you're ready. I think the 7x5 is ideal to start Then 6.5x6.5 Pylon prop on 3S, before going to 4S. 4S changes the low end ability since it will be heavier.

Happy Thanksgiving all !

what would a set of motor cost me for my tj ? sound like a good set up. i fly with tas he is a speed freak. i like to go fast too.

@JustGoFly

i see on your website : 500T Tractor Motor and 500T Pusher Motor
and they have a different axle diameter.
Sorry i dont understand the difference between a tractor or pusher motor,
can i find the difference explanation on your website?

i am only aware of brushless outrunner, not that there is a tractor or pusher version
thanks

'splained here.

You want a pusher.
You got my email address right?

I know... LOL I do have slow planes too when I am feeling old and my eyes can't see the fast @#$% planes.
I have the 500 size motors waiting my esc's. And yes as you may guess I had to swap the bells out for a Kv jump...
1950Kv to 3380Kv I will still run 4s making this TJ , 500TH on 4.5x4.1....
I have 2 CC 80amp esc's so I can play with the timing and custom cut off voltage.
Should have it ready by next weekend to try.

BTW what do you think would be a good timing to set these at to start with?

Tas,
I'd start with NORMAL and move towards HIGH.
High provides more performance and lower efficiency. Use High only if you have start problems. The 4S should kick it into very high performance - no need to squeek out more, since it will also drive amps up.

this is exacty what i want . this model is hard to come by and i want this twinjet to be my 'show n go' delta wing . (more for show) lol .i have a stryker c and a hobbyking radjet 800 that serves the need for speed. so 80-90mph is good for me on the twinjet.

if i get my hands on another twin jet. i will make this one my my fast flyer and glass and custom paint the other jet .

Anyone still alive over here in TJ Land ?
No progress on my end with my TJ's. I finished an indoor plane and it has made my winter flying extremely enjoyable. Guys are asking how it's possible I can fly under 5 mph It takes the right plane to move into the next stage of flying and I'll be looking at Precision Aerobatics, 3D Hobby Shop and Extreme Flight and some others for a big bad boy for summer hovering on the flightline. I finished a pattern plane and have a couple other planes slated ahead of the TwinJet. I hope I finish them all. My plane pez dispensor needs to be full by April, since all my free time will be spent flying at that point.

I can't wait for better weather, but in the interim - it's build time !

What are you guys working on ?

Vinnie

I'm starting to think about doing up mine with two of those Turnigy 2730-3000s that you guys keep prattling on about. I have a few copies of that motor and so far I've had good luck getting power out of them. This business of six or eight watts per gram doesn't sit too well with me, though. Maybe I'll just settle for 4W/g and see what kind of speed the plane delivers, then move on to bigger power when I can't settle my thrill needs at that power level. Eh?

Well I just got a new in box Twin Jet in a trade. I'm a beginner pilot so I have not started the build yet, have an AXN floater on the way along with a brushed ESC and lipo for the TwinJet. I have been meaning to post as I have lots of questions before I start my build. I have been flying helis mostly.

Shahram - if you've never flown a plane before you might want to start with a trainer, then an aileron trainer before stepping into a TwinJet. Everything moves very fast on a TJ, but as you fly more and more you'll find the plane seems to slow down. You react faster, you plan better and it gets easier. This is why it's a progressively learned hobby. Guys who when they first start think everything is moving so fast, decide within a month that their trainer is too slow. If you start with a TwinJet, then everything will be moving REALLY fast, and landing requires a good approach - which is learned from many times flying.

Good Luck,
Vinnie

I second Vinnie's recommendation.
Also if you can find a friend to help teach you, you will crash less, learn faster, and have more fun.
(That is all you need to read. The rest is just fluff.)

WARNING-trip down crash memory lane!

Years ago I trained by flying a Multiplex SkyScooter (It is that old-no one remembers it.) I even upgraded to a brushless motor (noone had lipos yet except from cell phones), modified it to include ailerons. I thought that I was pretty good, so I decided that the TJ was for me. I got Kontronic Brushless motors and 10 cell zapped & matched NiMH batteries. It was heavy (can't remember how much), but it had tons of thrust. On its maiden flight, I threw it like a fast ball, hard and straight, jumped on the throttle, and then I just kept adjusting my sticks to keep it flying while trying to trim it.

By the time I got it trimmed and could turn it, it was way small. I turned it around and reflexively corrected the wrong way. Something that now would have been second nature to me (left is right, right is left, prop up the lower wing with the TX stick, etc) but at that point I had decreased the throttle and lost enough altitude that I couldn't recover. Now, I can fly a 24" MicroJet at about 80 MPH 5 feet off of the deck.

I pulled out my old TJ and now 7ish years later, I know how to repair foam so I fixed the broken off wing, replaced the spar, repaired the fuselage... now I just need to finish my other planes before I'll have time for the TJ to put in motors and (lightweight by comparison) lipo batteries and test fly it. I do have a back up "White Eagle" TJ fuselage that I will build up to be a "hanger queen", "show boat" plane.

I hope I get to it done by June. I'll post when I do, but you by then will be an acomplished fixed-wing pilot, and probably have your TJ built.

Oh I don't plan on flying the TwinJet right away, it was a trade for something I didn't need, that's why I have a plane that is past my skill level. I have a powered glider with ailerons on the way and will learn on that. I really don't want to fly something without ailerons as roll is already natural to me. I have been flying planes in the simulator for quite a while now. The only thing that is hard is landing, but half of that is because I can't see the runway in my peripheral vision as I make my approach, so I don't know where I am.
