Status: offline 		got my Showtime 90 yesterday, LHS was closing for good, and they've had a showtime in there for quite a while that i kept looking at.

retail price was £215, a few weeks ago they said i could have it for £180, last week it was their cost price £171, but just as they was closing the doors for the last time they said i could have it for £160

just need to decide how i'm going to power it now. i've been enjoying going to my local electric club latly, but i think i should have got somthing this size made for electric rather than convert an IC plane.

quite tempted to go the petrol (gas) route, after using electric i'm not keen on using my messy glow planes, so i'm thinking Zenoah 20 or 26.

anyone used the Zenoah 20, is it enougth or is the 26 really needed?

first time i've looked at servos ect for this size plane, didn't realize how much more they cost.

Status: offline 		If you have your heart set on petrol, then I'd go for the G26. Weight is a big concern, so pick the lightest, most powerful engine you can find. The Showtime is really a borderline plane. It will work with gas, glow, or electric, but gas is a little iffy. I'm running a 26cc on mine with great success.

I hear ya on the servos. Those high torques ain't cheap.

Status: offline 		been reading most of this thread to get as much info as possible, i think i still want to go the petrol(gas) route.
HS5645MG servos for all surfaces, i think seems to good,

any one actually used the Evolution 26GT?
i know price is more, but to me it looks like it might be a better fitting, and also more powerful maybe a bit lighter.
this wont be getting built up for a couple of months, i have the model which is technically a birthday present, thats not until end of June.
for the engine & radio gear it might have to wait until i get a redundancy payout that might not be until August - October.

give me plenty of time for research for the right choices.

having said that the saito 125a looks quite tempting, but i want to get away from the glow mess

Status: offline 		The Evolution 26 with a tuned pipe would be the perfect combo. I think there's a guy around here named Dick H...(something) that used this combo. Maybe someone will chime in. I was thinking of using the Evo., but it is too expensive for me.

Status: offline 		I liked mine with the BCMA 26cc. It had plenty of power for hovering and pulling out of a hover. I did not add any tail weight, but I put the rudder servo in the back and I put the Rx battery on a tray I made about 1/3 back from the trailing edge of the wing in the tail, (I think it ended up being about 8" or so aft of the trailing edge of the wing).

I'll try and embed a couple short videos of me during some first attempts at hovering a long time ago. The links are below just in case RCU doesn't allow for the embedding of videos.

How'd you get your engine to do that!! I have the same setup, but it takes almost full power to hover with little pullout. Did you reduce weight or something?!

Status: offline 		That was the APC 16X4W, I believe. The other one I ran was the Xoar 18X6. I really prefered the APC. It brought the engine up to just about 9k RPM's, so I had a really nice throttle range.

The oil is Klotz SuperTechniplate from Tower Hobbies at about a 40:1 ratio.

This was after a few gallons through the engine, so it was nice and broken-in. The biggest mistake I'm finding that people that move to gasoline engines are making is running the engine rich during break-in or expecting the engine to be broken-in after a few tanks like in most glow engines.

The gassers really pick up a lot of power after they're thoroughly broken-in.

I didn't do anything to keep weight down except move the battery pack aft instead of adding weight to the tail.

Status: offline 		You'll find that these engines break in much more quickly on non-synthetic oils and from running higher RPM's. As long as it doesn't get too lean, there's nothing wrong with letting it wring out a bit. Adam at BCMA told me that as long as I kept it at around 9k RPM's max it wouldn't hurt it.
