Hi guys, does anyone know how Mr Jim Armour's Tutor, remake, flays. Jim is a very talented builder, I have a couple of the old tutor kits and I think what Jim did with his is really cool. Mr. Ted Fancher wrote an article on the plane many years ago but I don't have any info on the results. Is there any changes recommended? If anyone has any information I would appreciate your input. (I have a couple of Mr. Bowman K&B 40 remakes and they are great and I believe this plane would work out great for them.) Gary

Dunno about the mods, but the little 44" TF Tutor kit is typically pretty heavy already. Adding a 10 oz K&B .40 to the nose and the lead to the tail required to balance it would be a very serious handicap. A B.40 would be a better choice, or a light scratch Tutor with a good .25 seems like a better combo to me. H^^ Steve

Hi guys, this is one of the pages showing Jim's Tutor, its not the same as a tutor. Jim increased the wing size, fuse is longer, its not the same as a kit tutor. Jim took a kit tutor and made it his own. I hope the picture comes through, its a great looking ship. Gary

Hi Gary,
My question is which K&B 40 was redone. I have an older style K&B 40 with dykes ring and the smaller front end with "Stan Powell type mods" done to it and it only weighs 9.1 oz which puts in in the OS LA 40 weight range but with a lot more power. If you have the new bigger front end I believe MECOA has the parts to change over to the lighter smaller front end and save you some weight if that is your goal.
. By the way, I believe K&B changed over to the beefier front end primarily to hold up to the strains of R/C sport Pylon racing.
One advantage that the K&B does have is that it is longer than some other engines so you can move move most of the engines weight back without having to mess with an extension.
So Gary, this was just a little more K&B information for your benefit and I hope it helps and best of luck with your project.

Hi Pat, thanks for information, I have the older type which weigh around the os max. Sorry, forgot exactly what they weigh, but you're right they are close to the os with a lot more power. Mr. Frank Bowman re timed and tamed them down and they run and sound just like my old tigre's. Have a great day, Gary
