Exact flight time is hard to compare because with the stock motor, I was using a 1300mah bat and with the new motor, it needed the weight of a 2200mah up front. It flew for what seemed like forever on the 2200, including doing the WOT climbs. lol. Will have to see exactly where the battery finishes on its next flight.
Yeah.. I read somewhere that some EMP/Turnigy motors are just rebranded.

It's definitely 60mm, 75mm is a long way back.
To be extra precise, I like 61-62mm
Main difference I find between good and bad cg, is throttle changing planes attitude, whether it will stay level at all throttle settings, or dive/climb at different throttle.

Help with FPV airplane selection

I would like to buy an new FPV airplane. Could you help me with decision?

I was thinking about.

or
Bixler EPO 1400 Kit

Thanks in advance for your opinions.

I couldn't get to the website for the Sirius to compare the two planes.

The Bixler is certainly a great plane for FPV or if you are just starting out in the RC hobby. I own a V2 SkySurfer which is easy to fly and mod out for FPV.

If you are looking for a true FPV platform with a bigger cargo hold, Hobby King has a model called the FPV UAV composite. It is fiberglass instead of the foam and in the pictures they show the number 168. I don't know a lot about this model but it or something like it might be what you want.

Here is also Skywalker Sirius 1500 to look at:
http://www.foxtechfpv.com/sirius-150...der-p-497.html

I am not already or completely new to RC flying yet. I already have Art-Tech Diamond 2500 2.6 meter glider. And had HobbyKing one meter Flying Wing. And I used that Flying Wing also for my start to FPV. I had only 10 FPV flights with it and I lost it. It was great flying wing since it was easy to transfer. A lot of fun. Nearly not destructible. But for FPV start it was not ideal since it was not so much stable airplane.

So now I am looking into something more stable for my FPV start. Which also could be easy to fix and possibly crash resistant.

I always had either EPO or EPP airplane. Which was not so difficult to fix. Would not be HobyKing FPV UAV composite fiberglass very difficult to fix if needed? Is composite fiberglass crash resistant?

I agree foam is better than fiberglass and sticks.

Here is another foam FPV plane called the Skywalker.

It was made for FPV flying.

Yes, looks great. Thanks.
However I would like something cheaper for my FPV starts maybe. I had only 10 FPV flights with my flying wing. And would like to avoid big investment to what I do not know much yet. That it is why maybe Bixler or Sirius could be ideal choice for now.

Yes, but I want just cheaper airplane for now. And then when I will have some reliable FPV system, then I can upgrade/buy another airplane if needed.

Help with Bixler motor trouble.

I received my Bixler and finished assembling the fuselage. One thing I noticed was that the stock prop adapter had marring on it, like someone had used a pair of pliers on it. I spun the motor and could see that the shaft has a slight bend I'm wondering if I got a return.

I tried to remove the motor, but the motor wires are stuck with the hotglue on the motor mount. So I gave up on that. I went ahead and cut off the stock prop adapter right where it ends on the shaft.

Now that I spin the motor with the rest of the shaft cut off, I can still see that the shaft is bent very slightly. I'm thinking about trying to straighten it with a pair of pliers by hand, but I'm worried I might break off the motor mount. Should I even bother?

Here's another problem I'm running into. I tried to mount a 2.3mm prop adapter onto the shaft, but it doesn't fit. I tried another one and same thing. I took the plane today to a hobby store to buy another 2.3mm prop adapter (thinking that the ones I had weren't machined properly. The guy measured the shaft and it turns out its 2.36mm. He couldn't get the prop adapters to fit onto the shaft even by trying to pry the prop adapter apart.

Should I drill out the hole on the prop adapter to fit the shaft?

This is really annoying. 1st, the shaft is slightly bent, 2nd, the shaft is larger than 2.3mm.

What are my options?

Just a reminder before "thread boss" AJ Baker appears. This thread is NOT a FPV thread.

We digress. Thanks for the sanity check Prof100

To keep on the thread I will say the best choice for a low cost foam plane is either the Sky Surfer or Bixler. They can be flown almost right out of the box or modified to whatever you desire (like FPV)
