It is always hard to say which plane is best. I think the two planes are very comparable in flight stability and efficiency.

I think you need one of each or maybe two of each. Both planes fly great. they have a little different personality but once in the air most flyers couldn't tell the difference.

I really like the new Grim Reaper XL. It is easier to balance and a little thicker airfoil making it a little easier for battery installation. It doesn't have quite as much working area because it is a smaller plane than the Gladiator but if you keep it light you will have plenty of room.

The Gladiator XL is a great plane too. It has a dedicated following and some of the best videos have been shot with it. We actually sold out of them this month and had to get the production line going to keep up with orders. It is bigger and very low drag and higher penetration and possibly a little faster but like I said once in the air both planes are designed to be very stable at low speed and have a good range of speed depending on the motor.

One of my design priorities is something you may not have really considered. We have designed these planes to be stable at low speed with a load which is important when you launch. You don't hear people discussing how to build a bungee launcher so they can get their planes up to speed when discussing our planes. Having a plane that also can fly slow helps when you are landing. You can land in a smaller area without as much risk to the plane or equipment if you can land slower. Top speed depends on the motor setup but if you are going for long flights you will need to be conservative on the throttle for the best miles per amp. Our designs are efficient flyers when compared with similar sized planes of the same weight.

Sounds good to me. I have only tried it once because someone here told me to but I have never lost any bearings. Except for one on my 3d plane these are all $17 motors so I don't care and I have done hundreds and hundreds of flights with no problems. I would use 3in1 lube just because i have it.

I left the open back on the motor mount to give access to the bearings for lubrication.

I used to lubricate everything but started to get a greasy build up and dirt in the bearings. I had a couple of motors that I wonder if had premature demise because of the dirt and possible affect of the oil on the wire insulation and windings in the motor.

Moral of the story. Don't get too much oil in the motor. Repeated oiling starts to add up with a sticky residue.

Airframe is still fine minus all the cutouts where my gear use to be. Thinking of a straight flying wing then maybe add some FPV stuff. Long range for me, living where I do currently, isn't safe any longer given the airtraffic.
