There was a problem filtering reviews right now. Please try again later.
The kit went together smoothly with nothing but the screwdriver included in the kit, a pair of hobby tin snips, ant a hobby file. It took about four hours to put together (much was which was spent discussing the details with the boy; if you're building by yourself, it should go faster). Once completed, it operated quite smoothly.
Pros:
- Decent price (most model engines seem to cost quite a bit more).
- Ease of assembly (part fit)
- Type of assembly (all press fit or screws)
- Cycle animation is first rate (I particularly like that it uses an encoder as a distributor and "fires" its "spark plugs" at each power stroke)
Cons:
- There are a few locations where the sprue flashing on the plastic parts must be carefully removed of it will interfere with the motion of the model. (It's nothing you won't do anyway if you've built a few models like this before.)
- There's a bit of slop in the camshaft assembly. It's not really enough to be a significant problem with timing, but it's there.
- The idler pulley for the timing belt is not on the part sprue shown in the assembly manual (at least for the generation of kit I received). It is still in the kit, just on a different sprue. I suspect they changed two of the injection tools they use to make the parts, moved which parts tree it's on, and missed updating the instruction book. It's not a big issue, just be aware.
Overall, it's a fantastic kit. I really love that it uses grain of wheat light bulbs as "spark plugs" to show when the spark plugs would fire in the cycle. Normally, I'd knock it down to four stars for the instruction booklet error, but it simply runs so well it rates all five.
