I order my engines directly from Cyclon engines.
You can also order the engine in Germany
The quality of the engines is of a high level



All engines runs very well, very easy starting.
need some modifications for better performance.
I use this engine for Mini Team Race and 09 Diesel combat.

with aditional head shim + venturi of 2.8 mm it runs much better than the default 2.5mm venturi
prop 6x5 or F2D
In the Netherlands we have a rule in MTR that limits the prop size, minimal 7" props and normal available in the modelshop must be used.
For the JAK a 7x3 or 7x4 can be used, the standard graupner props are doing a good job.
It runs more happy with the 6" props

Marco
