Well, after just one day in the field with this demo, here is my 'so far' review of RedMax's Robin 2050 look-alike. The trimmer is a super-light class trimmer. It's about 9 lbs as opposed to the 8 lb Robin they appear to have copied somewhat. It's nice and light compared to the Stihl FS85's I've been running. But no doubt at all that extra pound is ALL down at the head. Light but head heavy. The gear box I figure... However, seeing the 104+ bump head is the only thing that interested me about the RedMax. It's NICE! Press the sides of the head to release the spool... The bottom, tap button and string eyelets all drop down in one piece. Personally, I really like the way this trimmer starts. It starts at idle and WILL start and run with the choke on. So you can crank it and get to the choke before it dies. However, on average it takes 3 pulls or so to crank it. Sound... it reminds me of the Honda 4 stroke trimmers, deep and throaty, and not real loud. At first I really hated the guard. I appreciated the cut-off knife after running for years with no guards. It was in the way for those things you reach over and trim with the back side of the string head. It also kept the trim swath cut down to like 16".... which for me is like playing with a kids toy. I also couldn't see what the heck I was doing when I tried edging with it. So I started loosening the screws on the guard to remove it until I returned it. As I was doing this it occurred to me just to twist it around give how RedMax attaches theirs. So I spun it around on the shaft to the left side of the head sideways far enough so the string couldn't touch it. I instantly loved this guard... Now out of the line of sight and an honest to goodness guard that really guards something while edging and trimming. IN FACT I URGE ALL REDMAX OWNERS DO THE EXACT SAME. However, this is where I had to stop and face some ugly facts about this trimmer that I did not want to. See, I found out right quick that this thing is not up to slinging more than a 16" swath... about 6" of string out each side of a 4" head. This made me stop to face the fact that the trimmer was already very lackluster in the power department. This thing is weird. It honestly really reminds me of a true 4 cycle trimmer. It has really surprising torque in my opinion. But it just cannot achieve the high powered screaming top-end RPMs. Plus I also caught myself running it about 3/4 throttle most of the time, which I would gripe at myself for because head speed really suffered. But I came to realize I was doing this for 2 reasons. The first is that was where the engine really seemed to run the best before just going flat so to speak. The other is that this trimmer is not all that smooth. It gives off the high speed vibes. The more you rev it, the more it vibrates and the faster the vibration. I also realized that under normal operation it gets HOT. The plug/plug wire is really exposed. If you are not careful you can get burnt in a hurry... and I figure years down the road it will turn into a shock point as well. I came very close to getting burned several times. Although I didn't get any burn marks, my forearm is 'heat sore'. This is not good at all considering Friday was a cool day and I spent most of it working in the rain. Overall.... I like the way it starts... I like the handles... I like the throttle lock... (would be better if you could set it where you want it) Love the bump head... Love the guard... (after rotating it) But compared to the FS85R Stihls... this thing is a total complete toy... I felt like I was using a homeowner 4 cycle all day and I was way slow on my trim times. It's a TURF grass only trimmer, and not a mean one at that. Weeds and grassy weeds just laugh at it. However, to be fair, Stihl doesn't offer anything in this weight class. I think I will run it a while longer and take time to get more familiar with the fine points of the RedMax design... air filter, carb adjustments if any, general crap like that. Fill the spool with Mega Twist (flys easier) ect... If it doesn't grow on me, I may return this demo and take out the StratoCharged BCZ2600.
