I purchased an EZstar MK1. It was in sale and come up for a nice price, so it's time to join the group of EZ flyers.
I want to equip it for FPV so I have a couple of questions before starting building it. I've read a lot of posts, very helpful but at least a couple of answers were unanswered.

1- First the motor. There is a little clearance for the prop and I have understood that the max usable (without cutting a slot) is a 6". I have several motors to use, including a Suppo like 2212-06 2200Kv, an EMAX 2212 1600Kv and others with lower Kv. My doubt is that the Suppo is by far too powerful and mabe the 2212 fits better. The real doubt is that with a so little propo the efficiency will be low. What would be the max flying time with a 3s 2200mAh? Is it there a better solution?

2- I've read that many people use to cut the two sections below the wing to have more sace to fit things. Do this weakens the fuselage? I think yes and will be less crash resistant. Your experience?

I'm thinking of not gluing the fuselage for the first flights until I'll have a better idea of the best config and weight distribution. At first I'd like to mount it using some fibre tape. It should be strong enough to keep the fuse on even it will add some weight. Correct?

Thanks for your support.

I'm using my EasyStar for FPV as well. There's a great thread about the FPV EasyStar at here. If you're going to use an outrunner, I highly recommend buying this motor mount. It's extremely well-made and very affordable. It allows you to use lower kV motors to run bigger props, which helps achieve longer flight times due to the lower amps. I have a 7x5 prop on my motor (the kV is escaping me at the moment) with room for an 8" should the need arise. I'm getting 15 minutes out of a 2600 mAh battery and that's also powering the camera too.

Very nice mount. I thought to build something similar, but apart aerodynamics it moves further up yhe thrust point and would pitch down the model when thrust is applied. You should increase the incidence and this would use power just to keep the model straight reducing efficiency.
Did you notice a change in pitch or the height difference is so little that is not noticeable?

Nope, no issue with the motor mounted at that height. It didn't (and shouldn't) make a difference.

I picked up the same mount Mike mentioned, very well made. Attempting to use a 1400 KV motor with an 8 inch prop. I was ready for a maden flight yesterday and as I was getting ready to leave the house it started to rain... drat drat and double drats. Hopefully Saturday I will get a chance to test the new plane out.

Another place for motor mounts. M/D also makes some Killer motors.

It must be sad when you get old and start to notice your eye sight going bad.

....and he blames the crash on the sun. Sure.

Gene I don't think he noticed it yet or is in denial.

How very dare you all!! Show a little respeck' to your...your...I would say elders, but having seen the state of some of you I'm not so sure.

Anyway, I'll have you disbelievers know that on Sunday I made a one hour flight to revalidiate my pilot's licence - and the CAA say I'm fit and competent to fly real airyoplanes for another two years, so there. As long as it's only the models that I crash I'll be OK.

That hour cost more than an RTF EZ2 but one will simply tax the serfs a little more to cover it.

Congrats on your pilot license re-validation. To me being ably to fly a real plane is well worth the cost of 2 RTF EZ's.

I wouldn't let the back seat drivers bother ya none about you not seeing the tiny camera in the tall grass. Missing something that small is not a condition of age.

Heck. I can't find things bigger than that sometimes and I am way younger than you.
