I'd like to know what would be the best gas engine to install on a stinger 120?

Gas or Glow

A gas engine. One that will have good vertical performance.

Troy

Any top in gas engine in the 45-50 cc range will work well, but you need to keep the engine weight under 5lb total.

I like the Fuji BT50. What do you think of that one. I think its on the high side of my price range, but i want a guality engine.

Thanks

Troy

Check what the total weight is, Have not seen one run but from post here are good engines. What is the cost of one.
Milton

From my local hobby shop 399.00

Have you considered the ZDZ40?

I had a Brison 2.4 on my Stinger 120. Good vertical at 15 pounds total, but no way was unlimited.

Dont want to get into a best engine bang here but here are some thoughts

Ralph at www.rcignition sells a 46cc engine complete with electronic ignition, muffler and engine mount shipped for about $400.00
www.RCshowcase sells a ZDZ 60 for I think $459.00 pluss shipping, You have to get a muffler for it and with a little work a $30.00 muffler from B&B will work.
I have found that if you can get a engine with electronic ignition for around the same range as a magnito engine go for the elctronic.
Just my thoughts
Thanks
Milton

I thought about the ZDZ 40, but i don't know much about them.

Whats the cost, HP, and weight and where can i find out about them?

Thanks

In doing a little experimenting a friend and I converted a 33cc Homelight chainsaw engine and installed it on his 120 Stinger. Here is what we came up with.

Weight: 4lbs (almost dead even)
Came with a BIG carb so no worries about fuel!
Turned a 16/8 APC over 10000 (let off before we damaged the engine!) No load on the engine at all!
Ended up doing the first flight (& the 2nd 3rd so forth) with a wood 18/8 and it turned the prop at 8100. We didnt have an APC this size at the time but we are going to get one. Would probably add a few hundred more.
But anyway the plane performed GREAT! After a few flights to give the engine a little run time we actually experienced hovering & unlimited vertical out of a converted engine.
If you would like to hear it from the owner him self or info contact me.
Best of all - Cheap to buy, Cheap to fly!

Has anyone got a photo of one of the 33cc Homelites after conversion? Thanks Captinjohn

I've got one Cap. I took during the conversion. The flywheel is not on it but was machined to remove the fins & the carb is not shown but it came with the equilivent to a wa 167. The mounts were changed before the first flight from the Dave Brown 120 to T-style mounts of the same size. A B&B muffler for a regular Homelight 25cc was used but we had to mill the exhaust hole in it a little bigger to match to opening in the jug. Very little work compared to most conversions was needed. Notice the size of the crank case. Very little volume so you get a good "fuel transfer" into the cylinder.

Pic was to larg to post. Email me w/ your address if you would like one.

I have a ZDZ 40 on my Stinger 120 and it flies awesome.These motors are great and the support is great from rcshowcase. Dave

Have you seen the deal RC Showcase has on a ZDZ 40

Don't want to get into 'this engine's better than that engine' but I will give you my preference. If gas, I would put a First Place 2.4 on it. If glow, I'd put a Jet 1.20 2-cycle or a YS 1.40 for 4-cycle. But since you asked for gas the FP 2.4 is my choice.

I have a Brisson 3.2 on my highly modified Stinger 120. Yes, it is a vertical animal, but not a good 3-d plane so far, with the extra wing loading. I'm still tweaking though.

I have a friend who flies a ZDZ40 on an Ultra Stick. That is the motor I would use if I did it over. Almosst as much power, smaller, lighter engine.
