that size model will be way overpowered with 60's the don smith model has 4 60 size 2 strokes or 91 4 strokes and it is about 135 in span.at your 105 inch span that is in the .25 size range.I built one from kyosho plans enlarged to 100 inches to match the scale of my stafford b-24 at 90 inch span and used 4 fox .25's it weighed 18 pounds.used spring air hd retracts and robart struts,flew fine had plenty of power.had to mount the tanks like it is done in the b-24 to allow for the retracts.used the astafford method from the b-24 for fowler flaps also but used two servos instead of just one and only 2 bellcranks instead of four.used seperate mini servo on each engine made setup alot easier.rudders were easy.just connect the outers to the middle via rod for a horn and a linkage running thru the stab to the center rudder.
Hi Aerwoof,
Mine is enlarged from Kysoho plans, originally its for U control 73" WS model but i have scaled it up to 1/14 scale = 105" WS. Yes you are right about the originally selected engine size!, when i calculated the wing loading with approx weight of 22lbs-24lbs tops it came to 50.45oz sq/in !!, just too much for this size of the model, now i have reselected and downsizeed to 4 x OS46FXs, but wing loading is still high at 45.35oz sq/in !!, i have never seen Staffords B-24 myself, but i have seen pictures of it..
Now it seems to me that i will have to down size again to 25s as you mentioned to bring my wing loading down, just wondering if it would be enough with these on abort landing situations!, would .25s have enough power to pull me out of trouble??
How are the mechanisums for the rudders and flowler flaps on Staffords B24?, is there any way i can get copies of plans which just show drawings of rudder and flowler flap set ups....i dont need full plans just that area to help me out with linkages set on my flaps and rudders.
Jojnnyo,
Sending you a PM...
