Hi

if anyone could help, I have a Svensson Pinto mid winger trainer, andI am trying to find informationwhat engine Ican use on it, anyone can help please?

Not familiar with that plane, wingspan would give an indication of what size engine to use.

The wingspan is1550 mm, thanks

About 60 inches W/S

Since it appears to be a three channel trainer (no ailerons) I would guess ~.19-.25.

The Pinto by Svenson has a 60" wingspan, an AUW of approx 4-4.75 lbs. and the recommended engine is .30-.40. An OS 40 LA would be ideal for this aircraft, light with more than enough power for this aircraft.
My Pinto had strip ailerons and probably yours have too.

Hi and thanks for your reply, I have an OS 46 AX, is it to powerful for it?

The Pinto was designed quite a long time ago when engines were a lot less powerful than today. However, as long as you refrain from full power dives etcetera I think you will have no problem with the 46AX.

So what do suggest the OS 46 LA or OS 40LA?

Thanks

I understand it that you already own a 46 AX. If so go ahead and use it. It will work fine, ut don't do violent maneuvers at full throttle.

Given the choice between the 40LA and 46LA I would choose the 46LA. It has a little extra power compared to the 40LA while still weighing the same. The 46LA is one sweet running engine that has become very popular in C/L stunt.

Hi and thanks, I have both engines the OS 46 LA and AX, so the 46 LAwill work well on it so no need to get the 40 LA

Thanks again mate
