I just completed the build of a PAU Sukhoi. Part of that build was the installation of MKS 777A+ servos on all the control surfaces. Upon completion of the installation I noticed a slight flutter in the elevator servos particularly when I switched from high rates to low rates or if I moved the trx sticks rapidly. After consultation with the techie at MKS he advised that the problem was caused by poor quality servo extensions even though the extensions used were heavy gauge. The issue is not the gauge of the wire, rather the alloy of the steel contained therein. This becomes increasingly important as the extensions get longer such as elevator servos in the tail of the plane. Today’s high frame rate high speed servos require a very clean signal, especially when Spektrum Power Safe receivers are in use. Additionally, Spektrum recommends that signal boosters not be used. MKS recommend the use of a superior quality servo extensions such as the ones offered by Power Box systems. I ordered them from Horizon (available also from Chief Aircraft), installed them on the elevator servos and the servo flutter problem went away. I am now in the process of replacing the wing servo extensions with Power Box (German made) extensions.

I found a new use today for that real cool sticky tape I was selling. For twenty year I never had a problem with mice. A nasty neighbor moved two doors down from me and now I have mice. You would have to see to believe. I stapled down a 12 by 16 piece of that stuff . and sure enough caught a mouse the first night. It sticks to there feet first and then the fur has no chance. After selling all that I had I was able to find it at Home Depot in a different size. Its called Bondera. I first used it for Batteries and gas tanks along with remote receivers. Thanks just had to share that

AGFrc A80BHMW super torque waterproof steel gear digital servo will be the great option which support to use with high voltage and damp situation. A80BHMW servo make almost 500oz-in torque with speed 0.11sec at 7.4V. While using voltage up to 8.4V, it can deliver 555oz-in super torque and 0.085sec high speed at 8.4V.

This A80BHMW is waterproof IP67 level up to 1 meter which allow driving in the rain, puddles, snow and mud. High reliable and durable patent gear design which can be longer service life. Full aluminun CNC case for fast heat disppation. High precision digital control circuitry.

Perfect for scale crawlers, 1/8 1/10 monster truck, 1/8 1/10 2WD and 4WD buggies, as well as 1/8 scale buggies and trucks. In addition, this A80BHMW is great choice for boats and other application which require high power, high voltage and waterproof servo.

AGFrc recently released two purple family members for the full CNC case servo. The" coreless guy" A35CHM and "brushless guy" A35BHM. Both of these two brothers are twins, so they have same looking, but actually there are two different "guys".

A35CHM with more power 9.5-12.5kg.cm, and work in wide voltage from 4.8-8.4V, which can meet your high torque but smaller size device. The “brushless guy” A35BHM is a little gentle with power 5.0-8.5kg, but still can work from 4.8-8.4V, if you do not need much power, this one will suitable for you.

Both of them are in medium sized, but they can run very fast, if you have the high request for the running speed, they may be your choice. Both of them are in high quality which is made from import Japanese potentiometer, Taiwan gear, high precision CNC material.

Below some more spec for your review first, more details, pls go throuhg here: https://www.agfrc.com/

2016 I build a house in a gated community, my neighbors all around me have RC airplanes, I am working but think when I retire I want to get into model airplanes.

2017 I buy the Real Flight system to learn on and I practice.

2018 Well let's start retirement in July 2018.

I joined the AMA late December 2018 and have a member number, this is a pre-requisite to joining the RC- Club where I live.

2019 January: The first meeting of the club me and my friend go to I sign up. Someone comes into the meeting with 3 planes in kit form to give away with and one glow engine OS032.
The president grabs the top ARF trainer kit puts the engine on it and sets it aside. He then grabs the next kit something like the Wright brothers flew and says who wants it, it is taken. Same with the 3rd kit... gone. He looks at me and says here is your first plane.

I scrounge from my friends a Spektrum 5xe radio, parts, and I buy everything else I need to go flying.

I build the Happy Fly trainer and have not been authorized to fly it yet so it sits in the garage.

My friend sets me up on a buddy box and I practice with him, I have logged 6 flights no takeoffs, no landings for a total of 60 mins airtime.

Feb 11 I get an email from a member of the club, I have asked some of you if you want any of the planes in my garage to show up on Thursday at 9 am.

That Thursday I go to his house at 8:55 am, and he had 7 planes in the various status of competition and he only had 2 left. One was an electric plane needing a lot of work and one was this monster of a plane a Great Flight 300L 100" wingspan just the finished airframe, I took it. So far I have dual servo elevators and ailerons installed.

So it looks like right from a trainer to a giant I go.
I joined this site hoping to learn more and I have.

I will soon have a 3w85cc twin for my plane that I hope to fly next year after I am really good with the trainer.

What I need:
I am an in need of a good radio something with telemetry. DX9 or 14 Futaba
A matching receiver for the radio
Prop suggestions the engine is broken in so maybe a 26 x10?
A spinner for the prop.
Some heavy duty servos
3 battery packs
Kill switches and off and on

Thanks for reading my first post follow along on my build!
Joe

2/27/19: Today I met someone from another local flying club and picked up my 85cc 3W engine. It has good compression and is complete, another needed addition to my project.

Does anybody know how much one of these transmitters is worth? I have one and I have been thinking about selling it so I wanted to know what you guys think.

Hobbico Twinstar:
I bought this off the club president for 300.00 back in 2015. He had only flown it twice, back then it had 2 blade 8 x 6 props and stock spinners. I found it really squirrely in the air. Knowing enough about propulsion, I changed out the props for 3 blades 9 x 5. this did two things for me. It smoothed out the flight characteristics a bunch. the props were larger so the motor acceleration curve smoothed out and produced less torque roll. the only real change in overall characteristic was I had to let the plane gather another 20 feet in ground speed to accomodate the thrust difference. Here is a list of all that is in the plane.
ENGINE_______________________
OS .25 nitro engines (x2)
OS no.7 glow plugs (x2)-medium range heat
Master Airscrew 9 X 5 3 blade (x2)
Dubro 3 blade no marks spinner (x2)

SERVOS______________________
*more to come

MODIFICATIONS______________
*more to come
- ignition glow driver module (possibly)
