Showtime 90 with 35cc gas
 

I just bought one of the new MT35cc gass engines and I am about to put a plane together for it. I was looking into the 72" Sbach featured in the new products section. It's very nice looking plane, but I already have way too many NIB arfs in my shed already. The closest thing I had to fit this engine is a Showtime 90. The reason I am starting this thread is to show how far the small gas engines have advanced. I have considered a few differant engines for my showtime in the past. I already own a YS110 and a YS140sport and I was undecieded on on these two engines but I never seriously considered gas because at the time I felt this option was just too heavy for this plane. But the gas engines are getting very close now at this size. Here is how these engines compare for ready to fly weight. I am adding 7oz to the YS engines as this is how much bigger the fuel tank needs to be for them.
YS110 27.4oz engine&muffler, 3.2oz mount, 7oz fuel. Total 37.6oz
YS140 33.3oz enginine&muffler, 4oz mount, 7oz fuel. Total 44.3oz
MT35 30.4oz engine only, with mount, exhaust, and ign. Total 39.5oz Note: Claimed weight the YS weights are my own.
The MT35 should put out power more in line with a DZ160, so this Showtime will be a pretty wild ride! I will post some pics when I recieve the engine and show it mounted.

i am watching this treads as i have a showtime that is hanging in the hanger without a motor

I might be able to make you a deal on a YS140;)

RE: Showtime 90 with 35cc gas
 

its going to be gas as i pulled off the YS-120 that moved it around quite well as i have been looking at the DL 30 thread on F. giants

RE: Showtime 90 with 35cc gas
 

Thats ok Krayzc, I think I'll be keeping the 140 around for another project. I would hold off on the DL30 though, The MT35 looks like a better bet. The DL30 carb would be completely outside the cowl on the showtime. I am going to make a custom manifold and exhaust for the MT35 and the whole thing will fit inside the cowl of the showtime. The only thing sticking out of the cowl will be the exhaust outlet. The MT35's have just come out and I haven't recieved mine yet but they look very on paper, 5cc more than the DL and a little lighter plus the carb is at the rear of the engine like the DL50.

I have a thread in the gas engine fourm on the MT35. There are a couple of links to sellers on it. I bought mine from southwest rc.

Just updating my Showtime project. Long story short the MT-35 never happened as there were major quality controll problems with the MT-35. This was a real shame as I believe it would have been a great engine if it were manufactured properly. I have just recieved one of the new DL 20cc engines and I will be mounting it in my Showtime. While it will not have the power of the 35cc engine it may be a better fit for the showtime as the 20cc engine package comes in about 8oz lighter than the 35cc would have. In fact, if I go with a 10oz fuel tank my take off weight will be slighty less than my YS110 option.

Very interested in your DLE 20 project. My Showtime has a YS 110 with tank at CG and the empty weight is 8.5 lbs. I love the way it flys for pattern but not happy with the 3D performance. Just have never put the time into a good 3D setup. The biggest problem I have is keeping the YS engine out of the shop. I have been getting about 3 to 5 gallons through the YS 110 then something always happens. I have 2 YS 110s just for this one plane and Each season one goes back for service because of loss of power. It would be great if I could switch to the DLE 20 and save me on fuel and $70 to $130 in repairs each year. Please post pictures of your setup

Does anyone have a link to an assembly manual for the showtime 90 4D. I have a NIB showtime and I'm thinking about putting the Syssa gasser on the plane. I'd like to know the distance from the firewall to the prop nut to determine if I need to make the stand-offs longer?
