Can I use a gas engine in this plane?
Hi Guys,
I need some help from flyers familiar with gas engines. I've been flying glow power since I started the hobby (8 years ago) and know nothing about gas engines. However, I'm interested and would like to use gas power in this plane if possible. To begin, I'm not sure what model this is. It's a biplane that was crashed and abandoned. I almost finished with repairs and need to start looking for an engine. This is what I know about the plane..Wingspan 60" (sounds small...but it's a bipe), length is approx. 53" from rudder to front of cowl. clearance is 5" from the engine mount box to the front of cowl. In terms of size, I would say that it looks like a 1.20 size. I have some pictures of the plane next to a .40 size somethin' extra for comparison. If I was to use a 2 stroke glow engine, I would probably go with a 1.20. I like to have some vertical. With that being said, can I use a gas engine in this plane? Any recommendations? I am going to try to find a used one on this site. Thanks in advance for your help, Dave |

Looks like one of these.
http://www.midwestproducts.com/super_stinker.htm If it is, and is properly built, you could use up to about a 35cc on it. Mine flew great on o Moki 1.8.

OK, can't resist! MVVS 1.60 gasser!
Great engine for dropping into 120 sized airplanes. Great performance, great economy, an because of the layout a dead easy installation. http://www.mvvs-canada.com/moreinfo.php?pid=3 |

Jake...
Yup...looks like a Super Stinker. If I were you i'd seriously look at the MVVS 1.6 gas engine. I don't own one but i've heard great things about it and apparently it's a real stump puller. I would say that a quad 35 would be too big and heavy for that plane. I had an 80' Midwest Cap 232 with a quad 42 and it was a pig.

I agree a zenoah is not the right way to go, too heavy,
but a ZDZ40 would work. The MVVS sounds right too!

Weight was an issue for me guys...and if you go on the different hobby websites, it seems like everyone is selling with Zenoah, Fuji, First Place Engines, Etc. To me, with my lack of experience with gas engines, the power to weight ratio would not suit the plane or my way of flying.
The gas engines that you guys have recommended appear to be more suitable!! Thanks, Dave |

35cc is too much of a good thing for this model,both power and weight,especially the conversions like Quadra and Zenoah.Prop clearance may be a problem too and the combination might smell too much like pork and fly like it too.
Check out the RC Showcase site and take a look at the little Roto 25cc and the RCS 1.4 and 1.8 engines which are naturals for 1.20 sized planes. Whatever choice you make dont ballast the tail if the model turns out nose heavy,but rather move as much of the radio to the rear as necessary to achieve the correct balance.I have on occasion carved a hatch in the bottom of the rear fuse to place RXs and batterys there rather than add dead weight.

Along the line of Kevins thinking I would recommend that you assemble the whole airplane with some servos (any will do just for weight) then take an old motor mount and put it on the front. Then start hanging weight until you get it to balance. Use that weight as a guide when you look at engines. If you find one close enough then like Kevin says moving the radio equipment and battery pack around should balance the whole thing without having to add extra weight.
