Default RADICAL and OPS Engines

Guess what, they are back! Many thought these motors would never come stateside again but now they are back in two forms.

First the Radical motors are now in stock through www.gotnitroonline.com. Those who have tried the 621P or 621T, they will tell your that they were the most amazing motors that they ever had, like modded engines right out of the box. Just looking at the sleeve, you could see just how aggressive the porting was.

Additionally, the OPS line of engines can be found at http://tkocompetitiondev.com/shop/in...p?cPath=38_113. These were originally sold through Nternational Nitro and many swore by there performance. Pick these up and you will be more than pleased. I will be bying more than one this time as they were impossible to find as of a couple months ago.

Ya, seriously, these motors are amazing. Many people stayed away because they did not know anything about the brand as it was not as established as OS, RB and Nova. What they did not know was that OPS had been making motors for the european market for around 25 years and many believe that they made the best plane and marine engines. They came to the US a number of years ago and made a big splash around the club racing crowd. They were fast, reliable, easy to tune, sounded like no other engine and in my opinion, they looked really cool. Now they are back and hopefully just as good if not better than before. No one knows why they went away for sure. Some say that the factory relocated and had to halt production for a time. You never know, they may show up on Amain again! I am really looking forward to this new batch! If anyone has experience with the 2008 versions, please give your opinions.

I have heard stories that these motors can last around 10 to 13 gallons without a rebuild! Yes they are 21's but I believe that there is a .28 as well.

There was a Fantom labeled version of these too (FR21 06 I think?), it sold for something like $219 too. As well regarded as these were among those who used them (I have heard of a few lemmons though) you would think the Fantom would be hugely popular at that price.

Thats right. Fantom did have an OPS based motor, but no one could ever find it for sale and the Radicals were for sale cheap on Amain.

Ya, the price has gone up, but I believe that they include the venturi carb, which was an option on the previous engine. The carb alone was like $60 so the prices has not really gone up that much.

Looking more into the price. Gonitroonline has the Radical version that comes with the venturi carb that used to be an option on the old motor, for $350. TKO Comp. Develop. has the OPS version (identical to the Radical with different badging). This does not include the venturi carb so the price is $290. The carb was a $60 option (I would know i bought it). So the prices are exactly the same as they were before
