Nope, just the outrunner. It does very well in my FMS Super Scorpion though!

Its time for a new sport jet from motion. This jet while good, has been around for what 10 years ?
Time for a large 90mm rebel.

I have been saying this for 70mm as well for a while. They had a huge hit with the Stinger 90. Then the Avanti 80 came out and was an even bigger success. Right now, 6s 70mm sport jets are really popular as well and I am surprised MRC/FW hasn't brought something out.

I do have a 70mm Rebel on a XRP setup on 6s and it is a blast! I'd take a V2 6s 70mm Rebel for sure. I'd take a 90mm Rebel as well. It would favor something like the Taft 90mm Cobra which looked great in my opinion.

What I'd REALLY LOVE to see as the next sport jet would be a foam BVM Bandit!

NO NO NO

Will need a High voltage esc, and new fan rated for 8s. The voltage of 8s need to be paired to the specs of motor or something wrong will happen:
1. Amp hug if lucky not to burn motor or esc.
2. Reduced time.

Recommend if want more speed

1. Put a more efficient fan: wemotec or Jetfan. Jetfan is better.
2. I nrunner motor 2200 kv
3. Make exhaust tube to correct diamater 76mm
4. Good real 45c lipo.

Cheers

OK, next question, I have a 90mm, 6Blade Fan With a 1850 KV motor, also have a 160amp hobby wing esc laying around, if I up grade the ubec, and ran a 8s battery set up, would this work, and would it be a noticeable difference in performance?

I purchased the tail cone from motion for the f-16 that I want to put on my stinger 90, can anyone give me some guidance on installing it? I assume I need to cut the foam off straight on outlet of the stinger first, then how or what is used to glue the cone on, not much surface on the cone for glue. Anyone that has done this, I would appreciate some input on it, Thanks

OK, So I'm in the process of gathering up the stuff I need to convert my stinger over to a 8s system. Have the ESC, 150amp hobby wing with no bec. Looking at UBEC's, they come in different voltage, 3,5,7,15 what should I be using voltage wise in the ubec for the stinger?

5. The highest as long as its under 6. Retracts don’t like 6 or over.

Looks like it's string or a zip tie...something flexible. Anything flexible should work fine as long as it can't get tangled or snagged on something.

The stock gear doors are operated thru 2 cleaves on metal wire to a servo.

Yes your right it does look like thread.
Capt Soap I was Having difficulty with setting up the two clevices and came across this method as a good alternative.
