The engine doesn't mount "straight". It mounts at a slight angle. Just use the existing scores from when the engine was perviously mounted.

Some broken vanes are not going to affect the engine's performance very much if at all.

Try putting it back in and running it after you clean it up THROUGHLY... At worst spray fuel through it to clean out any debris, but be sure any dirt of foreign particles are completely removed.

Once you get to the point that the training gear are all off, the included engine does a good job.


Re: Replacement.

After crashing a PTS, I found that I could order a new ARF version for just over the cost of the parts.

Consider ordering one of these. It will be much easier to deal with as the instructions will guide you through what you need to do.

Once you have it together, take it to someone ( preferably an instructor ) who can review your work and check trims, linkages, incidence, etc.

villa i checked the ailrons they were ok and not reveresed i got all the replacement parts today and im gonna try to get it together before the weekend i ended up ordering another trainer engine like the original the idle adjustment broke off and nobody has any replacement parts for these engines till december so when they do become available i will get them and have another motor if needed was wondering can you do any kind of welding on this material as far as getting the adjustment screw assembly back together i just want to get it back and learn how to fly it i just hate going to my basement and seeing it tore down!!!!

You're probably talking about an aluminum or magnesium casting. This would take a MIG or TIG (can't remember which) welder with a fine touch to repair. Cheaper and better to replace the part in the long run.
If you can provide the actual part numbers of the broken parts it would be easier to respond accurately.

Nothing really repairable there, just replace damaged pieces. There is a reason why these are out of stock. LOTS of them are getting broken.
