Hey guys.
Are you aware of any platform that allows to rent your RC models and parts for temporary use?

I believe I found an Ugly side effect of how the Spektrum AR636 initially powers UP and how it moves the control surfaces. I am certain that this is why my Elevator is acting UP in-flight and WHY the servo ( I am certain it's the Elevator) servo at times makes this loud jamming noise right after AR636 initial Power-UP !

The following Video is my E-Flite AT-6 Texan with the stock Spektrum AR636 and I have been hearing and observing a loud jamming sound from my servos due to the manner in which the AR636 initially powers UP. This is very hard on the servos! That day I flew my AT-6 Texan twice with the new GEN ACES 3-Cell, 2600mAH, 45C Discharge Lithium Batteries and it flew great but, I am still anticipating UP Elevator during turns and other maneuvers, otherwise the model tends to nose down.

Just to be complete, I followed the instructions carefully and TURNED-OFF the help of the AS3X features but, after my AT-6 Texan lands and I hold it, I can hear the Ailerons still moving very slightly! I don't need any help!

The Jamming (at times) is very ALARMING at best because it sounds like the servo is Jamming up on initial Power-UP and Initiation of the Spektrum AR636.

My beloved AT-6 will now be a hanger queen until I will install that spare AR8000 with Satellite receiver.

I have posted the section of manual for the AT-6 Texan so, you all can see that it states:

Once the AS3X system is active, control surfaces may move rapidly. This is normal. AS3X remains active until the battery is disconnected

Okay, here's my Video where you may or may NOT hear the very violent movement of servos during initial Power-UP of the AR636!

My flying buddy has a stock CA and a Walrus that he uses for thermal soaring and for full throttle aerobatic practice and experimentation. He was using a Timber X for aerobatic practice but its in need of major foam repairs. The CA is holding up to this type of stress with minor foam cracks and tears glued back with regular CA. He uses the CA SAFE System for orientation recovery .

The Walrus is about half the price and does not come with a RX so he is using an orange 5 CH RX for motor, rudder, elevator, ailerons, and flaps. The Walrus does not look like it would be a good sailplane because the fuselage is much fatter than the CA. However the Walrus is stiffer and there is less wing flexing. Walrus has a thinner wing section and with upswept wing tips has better rudder only roll coupling. The glide is faster and has better lift even without changing wing camber. The power to weight and aerobatics are better than the stock CA. The flaps offer full trailing edge camber with ailerons and can slow Walrus down unlike the CA. The Walrus prop shows stress marks and if it fails/seperates could cause a serious body injury during a power on hand launch. The Walrus would be a nice inexpensive aerobatic trainer/motor glider with the Timber X receiver in her. I'll be on the lookout for the similar looking but discontinued ELuna from Tower Hobbies.

Review Part 1 - RacerStar SIC2207 2688kv Motor - Thrust Test ;-)

Here is a link to the Video:

This item is courtesy of Banggood!

I'm always looking for motors with great thrust and efficiency.
I'm not looking for a motor that has the greatest amount of raw power at the expensive of efficiency, many motors can give you that.
The best motors, in my opinion, are those that provide excellent thrust but also excellent efficiency.
I thrive on speed but I also like to have more than 3 minute flights per LIPO pack ;-)
RacerStar has been the best budget motors I have purchased thus far.
When I was asked if I would like to test the RacerStar SIC2207 2688kv Motor I didn't even have to think about it ;-)
The answer was a definite YES! hehehehehe

So, in this video we're going to see what we get in the package, weight, length of the wires, and most importantly, thrust and efficiency numbers ;-)
In part 2 of the Review we'll install it in a Parkjet and see it performs in the field.

After getting some time off on a weekend (FINALLY!!!), I was able to get two of my beloved warbirds back up in the air: the P-47D and the E-Flite P-51D.

I got two flights in on each in some beautiful weather here in Texas, and it really did my soul some good. I will be going back out again tomorrow morning to fly before a dentist's appointment that will have me laid up for about three days. I'm expecting the flying will help to calm my nerves before the two-plus hour appointment and subsequent recovery.

I plan on flying more often. I talked with my wife about making flying a priority on Sunday mornings for me. She agreed, and has given me the green light. I am looking forward to getting fully back into the hobby. Like I said in my last post, it's been too long.

I was never really good at math, and after reading a bit about LiPo batteries on Google I realized my current electrical knowledge won't be enough to get me through the second airplane project (which would be building a ラジコンフォーム滑空機). These batts seem to have a lot of little "usage rules" and lots of math formulas, soldering, and electrical circuitry involved. That's why I decided to direct my research at that completely, but even so, I'm so dumb in regards to mathematics that I'm having some serious trouble understanding the basics of that. Next week I'm starting a crash course on electricity so that I can learn the basics to get on with and fix some stuff around the house without having to pay for it.

When airplane rests in still air, the weight of drop tank is the only force upon drop tank. In flight, the force of air on drop tank will become important, which is the friction between air and moving drop tank. The combined force will exceed the gravity force.

How much force on the drop tank in flight? I propose a simple test, use leaf blower to blow on the drop tank.

Most leaf blower works at around 150 mph, and diameter of nozzle is pretty close to the diameter of drop tank in most 90mm EDFs. So if the blower blows the air to the front end of drop tank at close distance, we can assume the air speed on the drop tank is somewhat smaller but close to 150 mph. Those has pitot tube can actually very easily measure the air speed from blower to the drop tank. The farther away nozzle from drop tank, the lower speed of airflow.
  • Secure a bamboo stick or 3mm piano wire on upright position. Secure the drop tank horizontally on the tip of bamboo stick/piano wire. This may actually be challenging to achieve but I will just leave it like that for future whoever interested to explore in experiment.
  • Turn on blower and point the airflow toward the drop tank in a headon manner (simulate the airflow toward drop tank in flight), keeping the drop tank in the center of airflow. If drop tank has stabilizer, it is easier to maintain drop tank at the center of airflow. The drop tank will be blown away from the upright position, causing the piano wire to bend. Measure the average
