    Aeroplus 60cc / 92" Edge 540 V3 from Limitless Aero

    With the AeroPlus 92" Edge as light or lighter than the 3DHS's, I am going with the 24x9. Based on my time with a 24x10 I can imagine that this V3 airframe, a 24x10, and GP61, one only needs to have the engine a bit off idle RPMs to hang it on the prop!!...Too much of a rocket ship for me, I...

    Aeroplus 60cc / 92" Edge 540 V3 from Limitless Aero

    Based on my experience with the 3dhs cowl opening and gp61 temps I saw, I had to have a straight line of air across all jug fins. This cowls inlet will defiantly straiten out the air flow but only looks like the top fins see the direct air. On the exit side this cowl has geometry that...

    Mini How-To How I built a 200W LiPo Discharger

    The best in my opinion is the newer version of mine with more amps per channel ( 40 vs 30 amps). It is the 408 duo I get my chargers from progressive RC. Discharging without is dangerous and leave cells un balanced. The Duo chargers provide the most info in an easy read way with arguably the...

    AeroPlus 60cc Edge 540 V3

    It's official (well at least the payment). Initially the VW scheme got my attention, but the red white and blue in flight looks sweet, especially with the guy behind the sticks in the mountains flying it. What is the story of the full size V3. Is it the latest from Zivko? I am removing the...

    Mini How-To How I built a 200W LiPo Discharger

    I built this today and the first test was better than expected without the use of Thermal epoxy. I have the two part epoxy but wanted to see how the temps were going to get before committing. It uses 4 each 4ohm 50 watt resistors mounted to two large extruded aluminum heat fins I found on...

    Mini How-To Build your own portable charging case

    Mine is the same case but got it from Progressive RC and it is in Gators colors.....This is a dated image. I use a 308Duo now. Also I got some of those 90 degree power cords to make a single power cord on out side.

    My burble concerns prior were most likely due to a loose throttle servo. My theory was at high amplitude vibration throttle levels (10-15%) the carb was opening and closing that was causing wired rich burbling sounds. That may be a stretch....All I can definitively say is since securing my...

    3dhs 92" edge 540 !!!

    You beat me on wake up. I had to be up at 0415 for week of travel. Cutting a ring around a headless bolt is simple enough for my dremil skill set. I will skip the fancy knots.

    3dhs 92" edge 540 !!!

    I had to read your process a few times but think I have it. The part that took me a second to get was, you are putting the modified 4-40 threaded rod into the wing tip hole where the blind nut should be. With the string from wing tip hole to root of wing, you can simply place the blind nut...

    3dhs 92" edge 540 !!!

    I know a few have lost the blind nuts in the wing tips. Yesterday was my turn. How did you guys install a new blind nut with minimal covering cuts?

    I was amazed how the GP61 performed yesterday. Below is the movie of the first start of the day with a 1 flop start!!! I simply rocked the prop 5 times to prime because I had not flown in a week. Falcon 24x9, 90 degree ambient, 6600 on ground and 8020 in air after 5 gallons. Thanks to Gary...

    In my opinion ...just the throttle. With the Choke arm short it allows for a nice short throw for push pull setup...A little extra force...but better at hiding the setup. Regardless of arm length if the servo is not locked down it is likely to dead stick in back to back flights....Don't...

    My recent lesson is to open up the cowl to let plenty of air get to the fins and not just the ones at the head but every single one. In my case I can assume the exits were not as big as they should have been. Do you have telemetry to get temps? My recent lesson comes to mind when you say...

    100% sure you have a fully closed choke? I see some crunched wood on your linkage. I had a time with starting until I discovered that my fire wall was ever so slightly keeping the coke plate open. The way I found out was pushing the choke plate by hand and it was springing back open a few...

    Yep thanks for your help along the way. How can I get an extra prop washer plate? Cost? Mine is chewed up a bit from using split washers in the beginning. Now I don't use lock washers and just torque the prop bolts to 90 in -oz.

    Cooling was confirmed to be my issue and I have the data to prove I did not cut my cowl enough for entry and exiting air. I opened up around the cylinder about a finger width and 3/4 in more on the top of the cylinder opening. I also opened up a new hole behind the two muffler pipes. Not sure...

    Thanks for the inputs. 1. I am convinced I need to open up cowl for exiting hot air and will open around the head. It can't hurt. I just reviewed some of my flight videos over the past few weeks. My conclusion is this rocket engine is sounding better and better every weekend. I just...

    I know I am asking for it all, but when this engine is on song i enjoy flying more. I fly slower and lower. A certain temp dose not help the fun factor. A good enough RPM somewhat. But a constant sound is real feedback you get every second. It may be an attribute of my exhaust that...

    Ok...I got some more data, after setting timing with timing kit..now no joke 29* I have two data sets. The first (good sound) was with needles leaned out that eliminated 90% of the gurgling at mid. The second was (bad sound) with both H and L needles richened 1/16 each which produces...

    Ok...after setting the timing to 29 deg ...It would not start easy...I am now about 32 deg and leaned out both for the results in the graph with a Falcon 24x9 prop.
