Cant say about that engine, but the radioe is great. I have a JR XS3 Pro and I love it. I would suggest this radio to anyone who plans on doing any racing and doesn't have a huge budget. It has been discontinued, but can found on ebay in hoards. With 30 FM channels to choose from and nearly everyone going to 2.4 ghz, you'll find yourself in a "roomy" situation as far as frequencies go. And other good things are a 50 lap timer trigger so you can get the most out of your practice and the smaller(cant remember the number) reciever that caomes with radio. Its so small it'll fit in anything, you could probablly fit a 6 pack in my radio boxes after it's all said and done. lol
