Hi There
Happy new year, anybody who knows these Spanish made engines, I will build a Christen Eagle 50% from www.emhw.de and will use an four cylinder 300ccm(18.3 ci).
Some comments please.

Hi Joen:

All I can say is that EVO engines are the best maiden engines in the world (top materials quality) and the look is fantastic. The 300 is a great engine with lots of power and a very low weight.

Here in Spain we´ve seen several testing engines and they are awesome.

hi Joen,

some pics of my new pitts from EMWH 3.04m wingspan. final weight 28 kg (with 2 receiver , 2 power box and 4x 5cell 2400nicd)
i use PEFA canister and a 36x12 Fuchs carbone (5100-5200 rpm). full throtle just for the vertical line :-)

Hi Radar.

I notice that you have a huge lead weight at the dome? Which type of batteries do you use AA or SC? I'm asking because I do have a weight limit at MAX 25kg inc. fuel, is this possible?

Great shots of a very nice plane.

hi Joen,

i removed this lead weight, because at the first flight the tail is to heavy and i have just this load for the test.
i use standard nicd 2400 SANYO (56gr per cell). the exactly weihgt is 27,460kg with no fuel and no smoke.
the rpm after breakin is 5300 to 5400 rpm.

under 25 kg it's impossible with the EVO 300 (7.4kg without muffler) and you need weight in the tail , all the battery are in the end of the tail !

i have a christen eagle and i use a 3w 200cc but it's better with a 212 4 cylinder...

Hi Radar.

That's bad news for me, do you have smoke pump and tank onboard or nothing at all?

I plan to use full pipes that will go behind CG , 1 receiver in back for the servoes with lipo supply, cables for servos fiberoptic.

Have you used the fiberglass plate in the front on the plane, you can save 1 kg by using balsa wood instead, which material has been use for covering?

I must have it down under 25 kg's inc fuel, by the way fueltank size? 1 or 1,5 l?

hi joen,

i don't use the fiber plate because it's only for the Christen eagle and the Challenger. i use 3mm balsa for this, but on my Christen Eagle i don't use the fiber plate , just covered with oracaver ( for the pitts to)

i don't have the smoke pump for the moment but i have the tank (1liter) Fanta bottle ! and 1.5l for the tank fuel (PET bottle) approx 18 min

but you can win some weight with the motor dome ...

BUT i use jumbo servo in my plane JR14021 approx. 130gr and ihave 2 per aileron, 3 for the rudder and 1 per elevator, with standar size servo you can save 800gr

with 1 receiver 1 powerbox and 2 battery you save 700gr (if you use standar 10 cell)

i have the competion version , with the magnesium version you save 430 gr and you decrease the weight of the tail.

i'm just worry with the cg...
