mvvs 26 petrol and tuned pipe
Hi there.
Can you give me a bit of info with regard to the throttling and mid range performance of the 26cc IFS petrol motor.
It's a toss up of either the MTW TD40 canister or the 3266 tuned pipe.
The motor will replace my problematic YS 140-sport and will be fitted to my X-TECH YAK - 54.
The model is 73" span and weighs almost 11lbs.
Would a 12oz tank be sufficient for a 10 to 12min flight, which is a mix of imac and a little 3d.
Prop wise either a Mejzlic 18 x 8 two blade or 16 x 11 three blade.
Oil wise, can I use 3W's own fully synthetic oil which is currently mixed at 50:1 for use in my 3W-55i powered WH Extra 300S.
Any info would be much appreciated in helping me to make a well informed purchase.
Regards
Aeroboy.

*- the engine uses 3/4 oz/minute, using an 18x8 prop. The 16x11 is not such a good choice.
*- oilwise, use what MVVS prescribes, and use that in all your engines, not the other way around.

RE: mvvs 26 petrol and tuned pipe
Hi Pe.
Is 3W's own oil not as good as made out then!!. I've only just purchased a litre and at £15 it's not cheap. I may have some difficulty in obtaining Mobil 1 2T locally it may well have to be mail order.
Is the 26 IFS going to be a good match for the YS 140 Motor that I have removed from the YAK due to problematic running and very expensive fuel.
Have you any good information regarding baffling the motor in a Yak cowling ?

For a baffling example, look at the " Evolution 58GX2 ign. LED flashing" thread at http://www.rcuniverse.com/forum/m_62...tm.htm#6255021
I will post a complete report soon in my own forum www.prme.nl/forum (working on it, but time is not on my side)

Aeroboy,
I also can't comment on the 3W oil, but I have to say that having seen the insides of MVVS engines running exclusively on the recommended oil, and parts from engines that haven't, I have no doubt that MVVS have got it absolutely right!
The oil is readily available from MVVS - I just need to check the UK postal regs before buying it.
BTW, the running in oil supplied with the 45, 58, and 116 is the same Mobil oil.
