I'm reading with intrest roy as my spe should be here this week.sounds like this engine will need a good run in and tune,keep us posted on your progress mate.Also how does she fly mate?

There is absolutely no mystery attached to getting your SPE 40 to run well, or does it need any longer than usual break in time. Just be patient with it and follow all the advice and suggestions that you have been given, and it's more than likely you will end up with an engine that is easy to start, relaible and a good performer. So many before you have found it to be so, it should be no different for you.

well i decided to get one after reading all about it on here.so far i am stoked with it.it was installed into a 72"cmpro yak and after some minor adjustments it fired up without any trouble

It is reported to be a user friendly and powerful engine which I am sure you will be pleased with.

What size prop are you using?

Thanks for the vote of confidence

I ordered a Dynatron starter so maybe starting will be a lot easier!

Not sure about the comment to fly it without a cowl. It is a pain taking it off as don't want to crack it trying to move it over the velocity stack, but theres a large opening into the fuse on the Extra 260 and...
Maybe if I can block it off some how and deflect the air turbulence?

its a 20x8 and it spins it with ease
went to get a 18x8 from the local hs but they had none.its the one i would use to fly with anyway[8D]

Yeah I might try a 20x8 soon as DA get the Xoar props in stock.

The 20x10 I have have has been quoted by a few US distributors of the engine as the ideal size prop.

i reckon it a trial and error with the prop.what did you end up doing about your run in fuel?

Used Motul 800T synth with BP Ultimate fuel with a 32:1 (150ml to 5lt)

I was lucky enough to get advise from the guy who designed the SPE40 and he recommended synth oil for the break in.

I sure hope it becomes easy to start as it hasn't been that yet. Again I am hoping the Dynatron will solve my starting probs as I do have a weak wrist/arm from a bike accident.

if it makes it easyer to start its worth it , hope it does the job.i did feel it in the arm the next day lol.took a while to get it goin as i had the ignition battery plugged in the wrong way(oops)but once that was sorted it fired up prety easly.used the recomended settings on the carby and away she went.i didnt have any fule and got a tank of a mate who was usin it on his 3w (synthetic also)and no probs

What oil did you use and what mix?

i will find out as it was a mates fuel mix he uses for hi 3w.
im thinkin just in case i will run some mineral oil for a few tanks(active2t)has been sudgested at 32:1

It gets confusing doesn't it. [&:]

The internet forums are great but you get too many opinions and info and you get pulled one way and the other.

Times like these I love my electric planes, pop a lipo in and fly! but I love the bigger planes and anything above 30 size in lecky plane is not cost effective.

I was just told ( from the FG site) that Motul 800T should be run on 50:1 and anything less creates deposits! See what I mean more *&%$ info!!

youre right there,confusing as hell for newbys but its great so many people are willing to help.we have some at our club that have heaps of knowlage but wont share it for anything.
ive ordere one of those flexy foam u can do 3dlookin forward to practiceing on that first[8D]

I am thinking of drilling 2 small holes in the firewall so I can get access to the high and low needles without removing the cowl.

I gather 2 x 2-5mm holes shouldn't weaken the firewall.

ive seen some planes with a few diferent mounting holes from previouse motors and old servo holes so two small holes isnt goin to bother it at all

The CDI for my SPE 40 engine is malfunction now. The rpm at idling is ok, but rpm could not rev up. May I know from where can I buy one better CDI for this engine? I know where to get the stock CDI but I would prefer a better brand.

Before you run out and buy a new unit just make sure that the internal carb screen is not blocked as when that happens it gives the very same problem.

CH Electronics manufacturers excellent ignition systems and makes a model that is a replacement for your original unit.

Karol

well its in and ready to go,done the final stuff today and will let her rip on sunday after a bit more runnin on the ground after work during the week

That'a very nice looking model you have there. Best of luck on your maiden flight, as we hope all goes well.

Karol

Comon crabbstar,,we know you can do it ,,best of luck with the maiden mate

thanxs guys
will keep ya posted

Go Crabby!

I maidened the Extra last week. Just 2 flights, but need to get the tuning of the carb right. Not sure if I should fly it with the cowl off or not to tune up.

Checked and re-checked. Confirmed it was the cdi problem.

Any comment on this RCEXL ignition CDI Model A-01 from China?
