Gas Engine Recommendation
I am currently planning to build the Dynaflite Chipmunk kit which has been patiently waiting in my "to be built" collection (which seems to grow larger and larger, but I digress). The plane has an 89" wing span and per the plans will weigh between 14 lbs. to 18 lbs. For the first time, I am seriously considering a gas engine, but having no experience with gassers, I would be appreciative to learn of the experience of others with this "Chippy" or similarly sized planes. I am thinking a 26cc would be about right for scale performance, which is my style, but at this time I need to learn more before buying an engine. Any suggestions as to size, brand, ignition type, etc. would be helpful.
Thanks for any and all comments. DaveB |
RE: Gas Engine Recommendation
i hear that da is coming out with a 30cc,give dave a call at desert aircraft

RE: Gas Engine Recommendation
Yea, a 26 might be slightly on the small side. I'd think 30 - 38

RE: Gas Engine Recommendation
I use a scale of my own, anything in the stunt plane type I use a 40cc if it has an 80 inch wing and a 50cc up to about 90 inches depending on type and weight. These are newer gas engines like DA or I use my Brison for the 40cc. In my 85 inch Extra I run a Zenoah G-62 with a mag ignition but I really like the G-62, very user friendly.
Take a trip into the gas engine forum and see what the guys there are running. A 26cc gasser in a plane that size just mite get it off the ground? If it did I wouldn't do anything real sudden with it!! |
RE: Gas Engine Recommendation
It would be better to use a bigger engine, and cruise around at half throttle, then to have a small engine screaming the whole time. I personally think its annoying. Plus, the 40cc gassers dont weigh all that much more.

DL55 is probably the cheapest "best route" or DA50 if u can afford it. I ran a spe43 in my 27% extra 260 and it has a span of 78" the power was ok, sporty but not enough to 3d it. It is 14lbs. I'm now using a dl50 and the power is really nice. Not crazy but very good. So at 14-18 lbs 50cc or larger is the way to go. The difference between a 40 and a 50 is not like people say, "crazy" or "insane" there is definately a differance but not a scary one. For example a spe43 will turn a zoar 20-8 at 7200 rpm and a dl50 will turn a zoar 22-8 at 6900 rpm. there will be a minor speed increase but the thrust will be though the roof. Thats what you want. Allows you to maintain energy in your flight easier. |
RE: Gas Engine Recommendation
I believe the Dynaflight Chipmunk was designed for a 26cc. It is a light weight plane built per kit. I have not flown one but have seen 3 different ones fly and they seem nice. It is more of a scale floater than a high performance aerobat.

This one would probably work well and won't break the bank.
