from what i have been told, a 21 engine uses less fuel than a 28 or higher engines plus it has higher rpm so it will be faster also

 

so yes 21 engine would be the better option mate

I think those comparisons were between the Hyper .21 and Macstar .28, both of which are available as standard in the Hypers, rather than .28s in general. A Picco P3.28, for example will absolutely hammer a Hyper or Force .21, but there are other .28s available.

 

I don't think a Force .21 would really constitute an upgrade on the Hyper .21, but there are more powerful .21s around.

lrp 21 is a good screamer ....force 32 /36 are a direct fit .i run lrp 32 in mine .....i get massive run times with lrp 32 last 10 mins when i cane it lol .lad i no has lrp 21 in his lovely engine easy to tune .....i do 3 tanks of fuel to his one (gives him chance to catch up)
