That will fit, but it might be a tight squeeze unless you remove the tray. Try it and see. I am more concerned that you may not get it to balance..

Hey guys! New to Rc-groups, loving it! I went and ot myself a Siren and probaably got for this setup:
Feigao 380XL 8T Kv: 2900ish
4:4:1 Planet Gearbox
Polyquest 3S 4500mah 30-50C
OEMRC Pentium 80A
Hitec HS 81´s
14X10 Cam naybee?
Weight of setup will land aroud 800grams/29 oz. To much?
Anybody have problems with the Carbon fuse disturbing the reicever/transmitter signals?

I use a AXI clone from UH with a Aeronaut 13x7, its very strange to mount the axi that the wires are not "rubbed" from the motor. I use two HS81MG in the wings, and a smaller one in the tail, the HS 81 is too big (also too heavy) in the tail, if you want to use it in the tail, you must cut off a lot of the carbon around the mounting hole.
The problem is for every more weight in the tail, you need a lot of more in the nose to compensate. I use a 3s lipo with 2250mah, the weight is about 170gramm, to reach the CG I've insert about 170gramm lead plus a external 5 cell receiver battery with 105 gramm.
The vertical performance ends about 30meters, so I want to try some different props next time. The speed is ok for me at the moment.
Perhaps I try 3 or 4 A123 cells in the future.

Finally flew my Siren and it did well with the 7-cell NiMH 2200's you gave me at the CCRC swap meet. Not vertical of course, but flew nicely and for a good while. You guys are all right about the Siren floating indefinitely in ground effect. Got to enable the flaperons next time--or course, the exercise is healthy, walking a half-mile to retrieve the plane...

Spoilerons and elevator mixing amount?
Flew the "Siren" this afternoon (beautiful day) and flipped in spoilerons at 200' and wow! did it pitch down!
Do you have a baseline recommendation about how much up elevator to mix in when you activate spoilerons? Thanks!

No, but you can start with a couple of mm and then test it up high with your Tx in programming mode so you can adjust it in-flight (it's best to have a helper.)
It sounds, however, that you're using a switch for spoilerons, which implies you've still got throttle on the left stick. If this is the case, I strongly recommend that you move the throttle to a switch - preferably a spring-loaded toggle or button - and use glider programming to have spoilerons on the left stick, so they can be dialed in gradually..

Can anyone tell me if this would be a good combo?
Great Planes Silver Series 45A Brushless ESC 5V/2A BEC
Great Planes Rimfire 35-48-1000 Out-Runner Brushless
FlightPower LiPo 11.1V 1500mAh 25C EVO25 3S Balance
( X2 Parallel ) (so I can use them in my other planes )
Hitec HS-65HB Micro Servos
Also has anyone tried using a 2.4 radio in one of these yet ?
And I forgot. If this is a good combo what would be a good prop size for it. Thanks
