Today was finally the maiden flight of my Fly Model Extra 330SC 91" 50cc electric powered.
This is my first experience with a 50cc size plane and I felt a huge difference from my 30cc birds. Plane flies wonderfully, almost no coupling during KE flight (just a little aileron mixing required but minimal).
Power system is working good but the Rotomax 50cc is getting too hot for my liking (even after rewind), ESC remains cold. Propping down is not an option as the thrust: weight ratio is already at the bottom of my preferred range so I may try to do some baffling to force airflow specifically over the motor.
We are approaching the hot season here so we can reach close 40C (104F) at noon.

I had to stop on the 3rd flight as the foam tail wheel ripped during a normal landing. I have just replaced it with a rubber wheel from a spare tail gear I had at home.

Spent some time today cleaning the shop and putting the decals on my new favorite bird.

Started a build log on the 3D forum for this plane. This will be a very relaxed build since I already have a 50cc Extra 330SC waiting for the maiden.
The Yak will be my backup plane in case something happens with the Extra.

First flight of last Sunday, this plane is pure fun
I wish my camera didn't have such a wide FOV.

I corrected a wing incidence issue which was causing snap turns to the right when applying up elevator in my brand new Skyline Raven 30cc.
Hope this may help other flyers passing through similar performance issues with their planes.

12th flight of my new bird, still mixing and playing with CG but I'm already loving it. I may write a build log for it since I took lots of pictures during assembly.
Sorry for the background noise but a club member was breaking his new nitro engine in.
Sorry also for the sharp cut at the end but my camera battery died right before landing.

I bought the Turnigy RC Alloy stand a couple of months ago and liked it so much that I decided to keep it at my shop and create my own version to use at the field.
I ended up modifying it in a way that it is now more simple and compact than the original one. It is a bit more flexible than I would like due to the choice of wood so I may replace the wood sticks by thicker ones. With the current 2x2cm sticks the structure flex a bit but is extremely lightweight.
I used only cheap materials and I believe the total cost was around $20.
Here are the steps:

Well, my Edge had its last flight today...
After a parachute maneuver the wings ripped the fuselage structure off and plane plunged to its death
I need to buy better planes or start flying a bit less aggressively the 6S lipo survived with minor scratches but the 5S was totally destroyed.
Here is a quick video edit of what was certainly my funniest and most awesome crash

Today I had my first in-flight fire accident
On the third flight I was giving some 3D tips to a friend using a wireless setup I just made. I took back the controls to land when I noticed some smoke and a stopped prop. When the plane passed in front of me I could see the flames on the right side.
ESC is a complete toast but the plane can be easily repaired. I was not happy using this 70A ESC as it was right on the limit (I get over 70A with a fully charged pack) so it was most likely an overheating issue.
I still need to test the motor but the BEC is working fine. Luckily I always solder the BEC directly to the ESC connector which means that as long as the battery is functioning I still have power to the receiver and servos.
I have a 100A and 120A ESC on the way so I should have the plane ready for next weekend.

Fire starts at 3:50
GOPR0497 (5 min 35 sec)


Just updating
Now I don't believe the ESC was the culprit but in fact, the victim.
When I started repairing the plane I checked the motor and it was not rotating freely (had a hard spot). After disassembling it I confirmed one loose magnet. I believe the magnet moved forward during the climb at full throttle (when the magnetic forces are at its maximum). When it moved it created a lot of mechanical resistance which caused the ESC to overheat when I applied power.

I checked motor and ESC after the first flights with this plane and both were getting just warm. It would be very strange for the ESC to burn

I have a new favorite toy: my Skyline Edge 540 30cc.
I've always wanted to have an Edge due to its famous 3D characteristics and I had an eye on this one for a while as I loved its looks so when it came back to stock for $207 I grabbed one.
Less than 10 flights so far but already loving it. I made custom SFGs for it since I'm addicted to flying with them.

Practicing hovers above the water. This is a maneuver I rarely do as I find it quite boring and very demanding on the power system but practicing over water added a bit of fun factor.

Woke up early on 31st/Dec and went to my new RC club (15min from home). I was able to make six great flights alone and I was back home around 10:30am. What a great way to close 2016
Happy new year!

Due to the wide angle lenses it is better to watch in full screen mode.

If you know someone who has basic sewing skills here is a step by step guide to make a customized wing bag. Nothing fancy but very practical. If the person likes to sew it will be definitely a fun project
Wing bags are quite cheap so not really worth the hassle for most people. Since I have all the tools and materials in hand it takes me around 30min to make one so it is really convenient. Having the ability to customize size, add pockets, etc is really nice too. I have one like this for each of my planes.

What you'll need:
  • Sewing machine: I'm using my Singer 20U which I used a lot when I was doing parachute repairs. It is an industrial machine but any domestic sewing machine will do the job.
  • Fabric: I bought a synthetic leather type which has a soft cloth backing (suede). This fabric does not fray so you don't need to bother adding trim tape or sewing zig zag stitches at the edge of the seams which speeds up the job tremendously.
  • Thread: I use nylon thread size E which I have plenty (parachute repairs);
  • Velcro: as required, see the pictures
  • Nylon tape: For the handle, I use parachute webbing but that level of strength is obviously not necessary.

One flight from today. Very windy, I flew only 3 batteries as the winds just got worse. Temperatures are passing 40C/ 104F here which create very windy/ turbulent days.
I'm practicing a new cool transition from 2 of my favorite maneuvers. It starts with an inverted pop top transitioning to the KE spin. It is the first maneuver you see in the video.
I'm also trying to improve my loncevaks (crankshafts), I want to exit the maneuver in level flight (upright or inverted) not diving.

After the crash of my Corvus 540 I picked my other favorite plane to have some fun. It's been a while since I flew this bird but I really love it.
I'll try to practice only on the Sbach from now on until I'm really in tune with it.
