I have long been a fan of RC Timer and have had great success with a couple of their motors, specifically the 2212/6 2200 Kv motor and for very lightweight applications, their 2208/8 2600 Kv motor. I have also been a big fan of their metal and nylon gear servos and have used them almost exclusively on all my planes for almost two years now. The servos especially are less expensive than many other alternatives and have proven to have excellent performance and durability. RC Timer also has the best deal I have found on 6x3 EMP props, so needless to say I am making orders from there on a fairly regular basis.
So since I am always on the lookout for products that work well that don't cost a whole lot of money, I decided it was time to try out one of their RC Timer 40A ESCs since I have lots of applications for this size ESC in my planes using either a "mild" or "medium" setup from our recommended parts list. So I picked one up and will be doing some performance and durability testing on it over the coming months.
I did notice one thing that I will have to remember about setting the throttle limits. Normally when I set the throttle limits on a Turnigy Plush ESC with the throttle all the way open, then plug the battery in, I get two beeps, telling me the high point has been programmed, then I go to zero throttle and get three beeps followed by one beep telling me it has programmed the low end. After reading the instructions and testing it, the RC Timer ESC when doing the same, gives three beeps to indicate it recognizes 3 cells on the battery, then after a couple seconds gives the two beeps, indicating the high throttle point has been set. Then when I go to zero, it gives a funny little series of beeps. So good that I actually took the time to double check the manual... :/
This RC Timer ESC is definitely less expensive than the Turnigy Plush 40A ESC at $13.99 plus $2 shipping, it is still $4 cheaper than the Turnigy ESC before shipping.
However, perhaps you get what you pay for, the RC Timer ESC is rated to a burst of 45A, while the Turnigy is rated to 55A. However, the highest I would be pushing this ESC is probably to about 37A with the 2212/6 2700 Kv motor.
I am also interested in how the built in BEC in the RC Timer ESC holds up to running the motor and 6 servos simultaneously. I will start off running it in a plane with one of the "mild" motors from our parts list and then work my way up to the "medium" motors. Along the way I will of course be evaluating performance to ensure it gives the motor and servos the power they need, heat build up when pushed hard with both motors and of course durability.
I will provide updates at the 50 and 100 flight marks. If there are no issues with it after 100 flights, then I might consider it a safe alternative to add to our parts list.
One final note I have noticed with RC Timer and their shipping to Canada. It used to be free and they still advertise free shipping in several spots on their website as you can see in the picture of the programming card above. When shipping was free, it would normally take 4-6 weeks (normally closer to 6) for my goodies to get from China to me on the west coast of Canada. Now that the only shipping choices are $2 flat rate or using DHL courier, I of course chose the $2 option. What I was pleasantly surprised to find was that my package arrived in just under 3 weeks, so if the shipping is going to be a bit faster, I am glad to pay $2. Ah, the perils of progress... :)
More to follow in the coming weeks.
