This review was first published in 2005, the S3152 servo remains on sale. The advances in servo technology haven’t really caused much excitement among modellers, have they? We’ve just taken for granted the servos’ steadily increasing rotational speeds and torque, and accepted that their increasing cost is the price of progress and reliability. Once we’ve paid our money, you might almost say, it’s been a case of fit, forget, and fly. And, because conventional analogue servos are so reliable, when most modellers think of digital servos - if they think about digital servos at all, that is - they only do so in terms of their relative expense rather than their advantages.

Having witnessed the performance of my young lad’s rubber powered BMFA Dart, and being highly impressed, I decided to scale up the design. In fact, it was not just his that caught my eye; it seemed as though (no matter how ham-fisted the builder) they ALL flew well - much to the delight of numerous children.

If you’re getting fed up with reviews of those ‘oh-so twiddly-twee’ electric models fitted with dinky little motors and are yearning for something a bit more hairy-chested (in fact very hairy chested, bearing in mind that we’re talking about a 50 cc petrol engine turning a 23” carbon prop), then read on. Rest assured, there’s no mention of Li-Pos in this report, and we definitely don’t secure the propeller in place with a tiny rubber band. This is big boys’ stuff! In a world where some ARTF manufacturers have difficulty producing even a humble trainer that doesn’t fall to bits before it leaves the ground (don’t ask. .
