I FINISHED THIS KIT AND WEIGHT 20 LIB, THIS KIT WAS PREPARED TO INSTALL RAMTEC DUCTED FAN WITH 91 OS, IS IT TOO HEAVY?
WHATS IS YOUR OPINION ABOUT MIG-15 OF CJM..
IF I WANT TO INSTALL TURBINE CONVERSION WHAT I HAVE TO TAKE CARE ON MIG-15.

Aldo, at 20 lbs. the ducted fan would fly but would have marginal performance. I have built several Migs for Bruce Sanders and other customers as turbine aircraft. The switch to a trbine is easy with this model and Bruce at Century Jet can supply the parts and details of the conversion.The turbine Mig 15 will weigh about 26 lbs. and flys well with a 17 lbs. thrust turbine.

THANK YOU MIKE, FOR YOUR INFORMATION, BUT IN VERY OPORTUNITY I TRIED TO TALK WITH CJM AN WAS NOT EASY,
WHAT DO YOU THINK ABOUT THE DUBRO TANK, ARE SECURITY ?
HOW MANY TANKS DID YOU USE?
AN THE C.G. OF MIG-15 IS THE SAME OF THE INSTRUCTIOS?
THANK AGAIN , SORRY FOR ME ENGLISH I LIVE IN VENEZUELA...
I'M LERNING.

Aldo, the Dubro tanks work good. We used 3 24oz. tanks in series on the bottom of the fuselage with the option of using a 4th tank. The thing to remember is to use the gasoline rubber stoppers and also to use 3/16 brass tubing with Tygon gas fuel line.I don't have a copy of the instructions but I think the CG is about 1 inch in front of the hatch. Mike

thank Mike, for yours help..

ALDO I have a CJM mig -15 built it two years ago and it is a nice flying airplane I first flew it with a Jet CAt P-80 that we found out later was not running properly had about 12 lbs. of thrust it used the whole runway here in Denver to take off about 500 ft. but in the air it flew fine with about 3/4 throttle
Since I have installed a P-120 and it flies great and lands easy.
It weighs 28 lbs dry and 33 lbs. with 108 oz. of fuel.
Yours at 20 lbs will fly great especially at lower altitude with a good fan unit
To conver it to a turbine is pretty easy if you need more info let me know.
