Default New 09 Diesel

The long awaited Parra 09 Diesel/glow is about to be released. Alberto is circulating these pics. It's available in AAC and ABC and upward or downward facing exhaust versions.
It will come with a glow head button even though it's designed as a diesel. It's a screamer not a lugger.

Performance:

This is from Alberto's email:

Today I tested Two wasp and I´m very glad with results.

I take only 2 runs of 5 minute each, sufficient time to set the head, and there is the result:

- Sea level
- 75% humidity
- 21 ºC
- Fuel; 20 Castor, 35 diethyl Ether, 43 Kerosene, 1,6 DII-3

Every time oil as honey, unburned, head clean with not deposit of burn.

PROP Ventury 3,30mm Ventury 2,70 mm
Graupner 6x6 17.700 rpm 16.400 rpm
Graupner 6x5 19.700 17650
Graupner 6x4 20.910 18.900
APC 6x4 20.600 18.800
NN 6,4x3,76 21.150 19.100
Kavan 6x4 yelow 18.100
Kavan 7x4 black 17.600 16.300

Engine stops and compression never loose. Very easy restart.

I test with Parra 2,5 silencer with teflon insert to adapt to exhaust tube and lost only 1.000 rpm and 20db.

Also I tested R/C carburetor and Parra muffler version with very impressive idle run.

Also I flown a Carbon Trifonov 1/2A combat model and gets time 2.7-2,8 sec/lap with 6x4 graupner and APC. Engines never was forced.

The manufacturer (in the Ukraine) also makes F2C and F2D engines. Believe me this one will hold together!

As anticipated the push/pull Diesel head button is similar to that of the Parra 15, so lends itself to modification for fitting to other engines.

My orders in, and it should be delivered with weeks.

Greg,

No final price yet but around Euro 110-125 I'd guess.

At Euro80 cents to the Aussie Dollar it'll be a steal!

Nice looking engine.

I never could understand why an .09 or 1.5cc class never got off the ground in the USA.

This size engine is still my favorite since getting an OK Cub .099 and McCoy .098 in 1951.

Some half-A models came out heavy and an .09 makes life a lot easier.

I think it is pretty neat for a engine. I hope they get it to production soon. It looks great.

The A class competition events are still being run a lot. But at first guys were running Cox Tee Dee .051's in this class as they could use the same plane for 1/2a or A then. But you see the A class event mostly for free flight competition not control line though. It may have been a lack of high performance .09 engines that limited it here in the USA. Many of those high performance .09 engines never made it to the USA. For RC flying, it was the lack of suitable airframes for the .09 engines that limited it a lot.

These engines are specifically aimed at the popular European and Anglo-sphere 1/2A Combat and Team Racing c/l market.

More pictures and details this morning.

The engine is nicely finished and figures are impressive. The crankshaft looks the goods.

Unfortunately only "combat" exhaust ABC models are currently available. I am waiting on news of "racing" spec exhaust (usual side) engines coming into stock.

The photograph above shows an ENYA R/C carb which will be fitted where the R/C spec unit is ordered.

Interesting, the "MK-17" style tommy bar compression adjuster shown in the blueprint schematic drawing was dropped for the more sophisticated "push~pull" vernier.

AMA Class "A" never favored the .09 engine displacement. For maximum power such as control line speed the .19 was top dog, first the McCoy redheads and then the K&B greenhead blew everyone away.

When the USA joined the .15 FAI competitions the K&B greenhead went right to the top of the list.

Bill Atwood saw the advantage of using an .051 engine in a half-A FF model he made his .049 and .051 engines which Holland Hornet copied and they also went the .049 - .051 route.

Bill Atwood developed the TD engines for Cox so they offered both the .049 and .051 sizes too.

While the K&B Greenhead .15 and .19 engines were proven winners the Greenhead .09 actually put out more power per displacement than either of it's larger brothers but the .09 had no place to go.

K&B announced their Greenhead .09 around 1954 and I ordered one from my local dealer but as far as I know they never made them until around 1957. When they did come out they were a real winner.

Early .09 greenheads had a long, open exhaust port and would sometimes become warped. K&B quickly modified the design by adding a web in the center of the exhaust port to strengthen it.

For racing I'd be inclined to cut the exhaust stack off altogether. It'd make it much easier to put into a cowl.

The small Enya 09 r/c throttle seems about the only game in town for a 1.5cc diesel. I have an original Oliver Tiger Cub 1.5cc diesel fitted with one from the factory.

I am on the reserve list, but will have to wait for more to come in to get a 'racing' version.

My lovely girlfriend got me a Parra 2.5 R/C Limited Edition for Christmas this year, and he's lonely.

After some 55 years the TD 09, a 1.5cc engine, is still the standard of comparison. As said the 09 size engines were orphans in the USA, not really paid attention to. I think the TD 09 would have been a good free flight engine, but I've only seen one or two at contests. There was some thought at one time that the FAI was going to go from 2.5cc to 1.5cc for free flight. The Johnson Bulldog 09 was designed to offer another American 1.5cc engine, but the change did not occur.

The Australian Sesqui 1.5 was also developed-in diesel and glow versions about a decade after the Johnson Bulldog, (Dan Vincent probably has one!....)-also in the expectation that the FAI was going to approve an imminent change from .15 to .09 for International competition. As we know this didn't happen second time around either-which is why not a lot of Sesquis got made.......and why they command big prices. The FAI did go as far as loosening the F1C class rules to allow the use of smaller engines in smaller sized models-called F1C(Mod)-but this never caught on (I was one of the few to try it)-this would have been around 1985/86. Then they jumped in boots and all with the F1J class and a 1cc limit-but this is now dropping in popularity.........(the need for US $200+ engines might have something to do with the decline in F1J)

I do have the Std and RC versions of the Johnson Bulldog. I wanted a Sesqui for a long time but the closest I got was seeing one that Stu Richmond had when he lived near me in Apopka, FL.

The Sesqui was gorgeous but I never did understand why the Intake was right in the exhast port blast.

I toyed with the idea of putting down a deposit on a Sesqui, (it was like the original Doonside Mills project you had to put up an initial deposit and become 'subscribed' to get one-then pay the balance when they were completed) but I was at university at the time and they were expensive even then-and with the amount of flying I was doing at the time I couldn't justify the expenditure. Wish now I had............... Quite a number of them subsequently formed the basis for various 1/2A T/R specials in the hands of a few skilled people. I don't know how many were actually produced. Peter Burford probably does. IIRC the intent was to offer a Mk1 a Mk2 and a glow version

Hi Jim, The Cox TD .09 was an awsome FF class A engine for me. I scaled up Lee Hines' Ramrod 250 design

to 450 sq"s. The entire model minus fuel weighed 12 ozs. I won a lot of class A FF contests with that model;

I even briefly set the Class A national record during a Flyoff with Ron Young and his 600 Texan. Then Ron

beat my time on his last flight, 10 minutes after I posted my time. Lee Hines' Ramrod 250 was a correction

to Ron St Jeans Ramrod 250 version, because St Jean made a mistake in scaling down to 250s" size. This

mistake was never corrected in the magazine or kit version. I'm guessing this was around 1966. So, like

the MVVS, the Cox TD had similar qualities, both are light and both put out excellent power(for the time).

There's something about the TD .09 that is just .... honest. Hard to put a finger on it.

But Dayyamn are they loud.

I would hope the Fora is better.  The numbers posted earlier were about the same as my AP .09 and LA .10 on glow with no muffler using the 7"-4p.  I am still looking for an excuse to try a diesel again.
