Quantity:

Silencer Select

Control Line Version (+£8.00 inc VAT)

Running In Service (+£15.00 inc VAT)

Our follow up project to the successful .56 is the .37 (almost .40 performance from a small .25 sized case). Yes, I know its been done before!.. But we were keen to see how much power was available from a .25 case, before you needed to change the case size (and therefore weight ) to a .40 (or mid .38 ~ .40 sized case)

Our answer was the J'EN .37....

"It starts easily, goes well, has great transition and it’s very smooth. It’s a quart of power in a pint pot and if it came in a tin then I am sure Just Engines would say “it does exactly what it says on the can!"

Quantity:

Silencer Select

Control Line Version (+£8.00 inc VAT)

As we've been asked for a .40 size engine for trainers and sport models that do not need the awesome grunt of the .56. 40 sized almost 50 performance

Customer Comments;
* I recently purchased a .47 from you and am just emailing to say how impressed I am at the quality and performance - much better than another manufacturer's .46 it replaced!!. D. Everest

* Paul, I just thought I'd email to say this JEN47 is a work of art - your photos do not do the quality and colour any justice - seems a shame to actually mount it up and run it!! S. Kidd

JEN .57

Price: £62.99 (Including VAT at 17.5%)

Quantity:

Silencer Select

Control Line Version (+£8.00 inc VAT)

Running In Service (+£15.00 inc VAT)

We’ve been working for more than 2 years on this project - to see how far you can bore and stroke a .40 case before it either doesn’t work, or becomes too fragile. We tried every piston and liner combination from .52 to .57 and after success with the .56 we have now arrived at a very nice .57!

"The JEN56 is indeed a .40 size package that thinks it's a 60."

Stunning purple and black
Wide range of silencers and Pipes available as O.S. compatible exhaust port used.
Retimed liner for more power

"This engine is happy whether revving hard or lugging a big propeller on the knee of its torque curve and when you add into the mix its excellent throttling and starting behaviour, there really isn’t anything lacking."
