If you have a Dremel kit that comes with the stone cutoff wheels they will probably work okay, but you have to be really careful because they're brittle. Something like this (link below) is best--a fiber-reinforced cutoff wheel. House of Balsa, DuBro and Dremel make them too.

That's the one I ended up using today. It cut it like butter.

Thanks guys. I can't wait to try out this motor with the Hyperions.

We are a few guys that will try the Rifle with Mega 16/15EDF 16/15/2 and Pletti Moskito 3, i guess there is no problem fitting these motors in the Rifle !? would HS-55 or Futaba 3110 be ok for this, anyone with experience using these servos ?

I got my 8$ hyperion inrunner it took a week to get here from Japan. The motor its self is a finned can and on my scale it weighs 78 grams. I hope to start the build soon, only thing is I need to decide if I want to work on this before I finish my 30%. I am kinda feeling the need for speed.

That motor will get too hot if you put a prop on it.

This motor will work with a 4.1x4.1 prop, I have used it

http://www.aircraft-world.com/shopexd.asp?id=2814 this is the motor I am gonna use in the 3400 kv version it was 2.50 to ship from japan and took only a week. Only thing is that ring around the motor shaft on the can is too large to fit through the hole on the motor mount so I got a some nylon bushing to stand it off so it fits.

well I just fell victim of the bad tail screws. Twisted the head right off, lucky i could get the stud out with out damage. Build is on hold till I can get to the LHS and get more screws. It seems like a good kit but I would be nice to have better hardware.

Happend to me, but no way I could get the broken screw out without damaging the fuselage. I contacted the compagny and Electrifly will send me a new fuselage when they'll get back in stock. I had to send the broken screw and a letter explaining the problem.

At least it's good to know that they are taking care of it. Also, good to know that Esprit sells spare fuses/wings and stabs.

Update build is almost done, I went to check motor function spun it up and the motor mount twisted loose. I am now attempting to glue it back but I am worried about it holding. It seems as though I got a Friday kit, well if I get get her all tied up hopefully I can maiden by this weekend.

I'm perplexed about these motor mounts coming loose. I'm sorry for the trouble some of you have had with this. I can understand how the firewall could come loose after a rough landing or something, but just spinning up the motor?

Well, it should be easy to repair. Pop it back into positoin--it should key in right back to where it was. Then just wick thin CA all the way around from the inside and outside-it should take only a drop or three on each side. Let the plane sit on its nose for a minute, then spray a LIGHT mist of CA accelerator down through the inside from the opening under the wing.

I've repaired a couple of these this way (from firewalls dislodged from a crash) and they have held for dozens (a hundred?) of flights after.
