SC30FS A CRACKING ENGINE

Strengths: Easy start seems to hold tune

Weaknesses: does need to be wet to start also don't forget to add oil to the crankcase for every start

Overall: so far only run in, its waiting the finishing of my DF but after 4 or so tanks to run it in I cant fault it and it certainly seems lusty enough, you just can't go wrong for the price, just don't use an electric start on it.

STRONG ONCE RUN IN

Strengths: Power to price ratio is good for the SC 120FS. I have one in a Seagull Yak 54 and now I have my plumbing sorted out it is running well. 10% nitro, fully synthetic lube.

Weaknesses: At this stage none. However my engine is only just run in.

Overall: I would say the 120 four stroke is a fair approximation of the type, versatile, powerful and suits a large number of larger 'club' sized sport and scale planes.

IF ITS GOOD ITS EXCELLENT

Strengths: Price, ease of starting, sound.

Weaknesses: Quality control could be better

Overall: i have two SC70's. One is excellent and the other is a bit of a pig. hard to start and poor tickover.

SC 52 FS - FANTASTIC VALUE FOR MONEY

Strengths: Easy starter, lots of torque, very cheap!

Weaknesses: may not last as long as 'quality' brand engines (there again it may well do)

Overall: Exceptional value for money, a 52 fs at less than £100, and it is happy turning a 13*6 prop in my Acrowot

QUITE A LOTTERY

Strengths: Cheap to buy, lots of retailers, good supply of second hand ones.

Weaknesses: If you get a bad one it's a BAD one. My local shop doesn't take tham back and refuses to believe they can be poor.

Overall: I've had several and now discovered something very useful. If your new SC is down on compression after a couple of tanks of fuel, check that the pushrod tubes are not holding the head off the body. Mine was, and I managed to resolve this an dnow its a lovely engine (sc 30fs). Sadley I now buy ASP instead.

GOOD VALUE FOR MONEY

Strengths: Easy to start and has good reliable tick over

Weaknesses: Like a number of 4 strokes the exhaust needs to be tightened properly in order to avoid stripping the head threads.

Overall: My experience of the SC91FS has been generally good. Throttles well and has a really good tickover and so far had no dead sticks.

GOOD VALUE BUDGET F/STROKE

Strengths: SC 120 f/s Good usable engines that dont break the bank

Weaknesses: Inconsistency in build quality.I have had two 120 f/s one excellent and still have it, the other was rubbish and down on power. Some engines have poor compression and are down on power while others match higher priced makes.

Overall: Gernerally good value for money. But a few examples I have owned have had poor compression from new and should be returned as faulty, no amount of running will sort the problem which seems to be distorted cyl head

SC52FS 6 YEARS OF FLYING, ADJUSTED FUEL MIXTURE A HANDFUL OF TIMES & ROCKERS ONCE. BRILLIANT!

Strengths: Easy to start, provided it's primed properly. Reliability is outstanding. Quiet and even running. very good value for money.

Weaknesses: Not a huge amount of torque.

Overall: Well I'd buy another if this one broke. Hours and hours of flying over the years and I hardly ever have to adjust anything or even change the plug. (I always use after run oil). Reliability that exceeds it's price tag.
