New 21 Engine

[Buckshot]

Tore the K-21 sample down last night to inspect after over two gallons of 60%nitro with 18%Klotz. Piston and sleeve fit and wear pattern are fantastic!

Buck, do you think the timing #'s will be beneficial for Mono's?
Certainly work well in an outrigger.

Yes, it will be a great motor for Mono, Rigger and Sport hydros. I plan on putting one in a mono as soon as Al gets the production motors in.

Great news !!

Depending on demand for the K21 and the K45, I hope to follow up with a .90 size engine. So much of the initial investment, spent before any engines are available, has to be spread out over the sales of many engines.

The material and manufacturing quality available to me is excellent.

I am confident that we can provide great engines. I just can not be as confident on a more expensive investment.

Great work guys! I'm excited to see these!

Great news AL, hope you get well soon

Well AL how's your leg doing? Hope it healing well for you and not too much pain. Take care.

Doctor says another 6 to 8 weeks before I can get around well.

67??

The world wide demand for 67 and 80 size engines really does not justify the investment. There is so much initial ivestment that has to be recovered in the engine's sale price. The most popular engines sizes worldwide are the 21 and the 45. Then comes the 90. To pay for the 21, I need to sell at least 500 engines. Same for the 45.

At this time the K45 is being run in the USA, Canada, Japan, Germany and Hungary, so I believe it will cover the upfront costs after a few more years. This justifies coming out with the K21, and possibly a 90.

If these engines become popular worldwide and it looks like the demand for a 67/80 will grow, there would be a slight chance to justify the investment. But, the costs, would make each engine more expense. And, that could kill demand for a K67 or K 80.

Personally, I prefer running 67 and 80 size engines. The power to weight ratio is really good and the boats are big enough to handle rough water. But, return on investment is hard to justify.

I have to agree Al. 67's are not nearly as popular as they used to be. Besides nationals or the handful of big nitro races, 60 class rarely makes it. Compare that to 40's and 90's where there are usually enough to 2 heats. The 21's and 45's performed great in Huntsville so bringing on a high performance 90 would be nice.

 

[Greg Wannamaker]

What your doing for all we nitro heads is nothing short of amazing Al, 21,45 and possibly a 90, well color me ecstatic! Can’t wait to rev these to the moon!

A short clip of Chris Grim testing a K21 during the Namba Nats in Huntsville. Driveline came apart at the end.

Thank you for posting this video. I have been told that this boat, with a stock piston/sleeve went 93.8 mph in Cincy.

 

[dlhwoody]

That looks great and I can not wait until they go on the market. Any idea what your going to charge per motor?

 

[Al Hobbs]

The price will be $350.00 plus shipping. I expect to have the K21 engines available to sell sometime around the Holidays. As they are made in Ukraine there are some delays and problems different than the rest of he world.

That is correct Al. There was even a small side bet placed between son and dad on the speed the 20 hydro was running versus the 40 hydro.
I know it's hard to believe when a Grim says it's a "stock engine", but this was out of the box with a CMB carb and an aggressive TT pipe.

That was the slow pass. Earlier run was crazy.
