i,m just about ready to start scratch building an avonds 1/10 scale f-14 & have been checking on those two fan units as to which pair to install! Jet Model products state that the dynamx can give u up to 15Ibs static between 21 to 23,000rpms, true?

the ramtach fan is stated to have a high blade pitch & o.s. recomends the ramtech for its 91 VR-DF engine, as it loads the engine better. you are suppose to get a higher jet efflux velocity than the dynamx at flight speeds, thus higher top end speeds.

i myself will most likely choose the ramtech as they will be paired in the f14 & the combination should give good climbing power & all out speed!

does anybody know where is the best & most secure online site to purchase the ramtech unit? best prices etc..
plus the os 91 VR-DF!
