qm-15
 

hello bob, i got a qm-15 that i'm going to build and i was wondering if any of the jett's 25 size quind of motor would fit in this plane, i now they used to fly them with nelson 15 but i want to put a jett and i know it's not for racing. but want to take it to the limits with a user friendly motor as the jett.
i currently fly qm-40 so i'm not worry about venturis or full throttle take offs.
thanks ray coletto

hey there..

YES definately. Lots of folks have built the older QM15 aircraft with everythnig from OS25 power on up. The Jett 30 size engines will fit fine, and the performance will be outstanding!

You will have to accomodate the muffler slightly - should not be a big deal - should fit like a typical QM40 aircraft. Most folks never used the engine side cheek cowl anyway on the QM15 planes.

Firewall may have to move aft and grow in size slightly.

Most of the QM15 planes had a 1.5" spinner - Jett spinner will be a perfect fit.

Its a great combination - definately worth trying.

OK THANKS,
now, i think i will go with the 35. does dub can makes a 35 LX? and probably a venturi for it?
thanks ray coletto

Yes,

He can make an LX out of the small engines - including the shorter muffler I believe.
If you want a venturi, he can provide that as well.
