SRT BH8015 Low Profile HV Brushless Servo Review

I was offered a team drive to use SRT servos for the 2016/17 season. This was a perfect opportunity to for a change as I had been using another brand for some time and was keen to see what other options were available. A deal was made I was made a team driver and I awaited a servo to appear in the post.

SRT servos are distributed by RPRC distribution. They have a few servos available covering the 1/10 market. As I only race touring car, I will be using/reviewing the BH8015 low profile servo

Once the servo arrived I couldn't wait to fit it into my Destiny RX-10S

Installation

No issues with fitment. The dimensions are the same as most 1/10^th low profile servos on the market. When you first take hold of it, the servo feels like a quality product.

The unit looks and feels high quality

The metal case makes it feel sturdy, but not heavy and cosmetically the anodising looks great.

Installed and ready

As I am racing indoors, I use a Tamiya servo saver. Although the servo has titanium & aluminium gears, no servo will withstand a heavy knock from the barriers!

Testing

I set the maximum end points on the transmitter & hit the track to see how it feels.

Check out the wheels!

I chose to race at the Hinckley radio control car club on one of their Saturday club races. This was my first visit to the club, but as it’s a familiar surface (Prima felt), it shouldn’t be too hard to get up to speed

As I had my 13.5 blinky setup still in place, they placed me in the 13.5 boosted class as there were only 2 13.5 blinky drivers here

Ready to race!

I had a little pressure on as I was in the same heat as 2 modified drivers, and a former world champion!

The car felt great on the new servo, plenty of steering and was very responsive. The car would change direction as quick as I requested & would centre very well, preventing me over-correcting the car to try to centralise it down the straight

That's a competitive group of drivers!

I qualified 9^th overall. Normally this would be considered not a great result, but as mentioned earlier, I was running 13.5 blinky where everyone else was boosted! I even out qualified a few boosted cars & was only 0.06 slower than the next car

Hinckley is a large friendly club

The finals were split that the A final was 7 cars. In my final, lined up 2nd on the grid. The start tone went & I immediately put pressure on car 1. The car was great, I was able to flick the steering where I needed to & the servo kept up with everything I asked of it. The leader clipped a barrier after 2 laps & I passed him for the lead.

Pleased with the result

Although I lost a little time with a backmarker, I kept a very steady & fast pace to win the final. Although there are 2 leg finals, I had to leave early due to other commitments

Summary

Most people won’t say you would feel a difference between servos, however your radio equipment is one of the most important things to get right if you want to  I felt that this servo responded a little bit faster, whilst still feeling smooth and having a finessed response. 

This servo is well worth the money, it’s a great quality & will fill you with confidence on the track. Try it, you will surprised how great it is!

Thanks to RPRC distribution for the opportunity to allow me to represent them as a team
