I remember the Metkemeier brothers in old Aeromodeller magazines as a kid, and their team racers, and think they were in England at the World Champs in 1978 in FAI Speed and the US one a few years back. They are the M in MB.Pretty serious players. Kind of heroes, or pioneers at least, for me. Emil Rumpel too. Long time ago. That is a fast plane there.

Default MB pylon engine

Hallo apseed,

to answer your question older or newer type MB engine. What is differnet.

The first MB 40 pylon engines where extremer, more powerfull but no easy to handle, often to difficult for the pylon racers.. So some userfriendly modifications came up.

The outlet port shape is complete different. On the older type much extremer.
The inlet porting ist also different, sometimes you have to use JB welt to modified type 1 to retuned in the size and shape as the new type, to became better handling.

Please see the pictures and compare what you see. Outside and inside a lot of different things you will see.

On all pistons you see the latest rod. This is the best. In the beginning you had a lot of problems with the rodbreaking, now this problem is solved.

I still use the old type for speed with better results but you need a lot of know how for consitend behavier on the engine.

Regards Michael

Todays FAI F3D plane run 230mph on the race course where the one in the above video did in a dive. Newer engines are out there with more power.

The problem, for me at least, is keeping the pistons in shape.
Rob is testing new piston materials, but the current ones have a tendency to elongate/enlarge the hole for the piston pin at the rear end, closest to the exhaust.
I've developped a habit of checking the slop in the engine after every run, because obviously this situation deteriorates very quickly and very "destructively" .
This is of course when you run the engine hard, "easier" setups are also much easier on the piston.
I finished the world championship in Sweden on one piston, but I noticed from the behaviour of the engine at the starting line that it was on it's way out after about 7 flights. So total airtime on that piston was about 20 minutes, before it started to let go...and that was a good one.

Any video?
As far as props Rudeboy, F3d Aspeed or airraptor would be the ones to ask about that.
