should also help. The 2p configuration and 15C continuous rating, gives 36A<br />

maximum. Interestingly they also quote a 2C charge rate, which makes field<br />

charging the cells more practical than LiPo.<br />

These packs are almost twice the weight but better that than lead. A small battery<br />

box mod and they fitted snugly. So that I could use the individual packs in smaller<br />

models 2mm gold connectors were fitted, and 4mm parallelling adaptors made.<br />

The CG came out dead on without the lead, and the Tiggy will now leap into the<br />

air and do consecutive loops with ease. This means scale speed is now half throttle,<br />

and ten minute <strong>flight</strong>s with power left to taxi back. I could still experiment with<br />

different propellers but it all works fine so what’s the point if the model flies well?<br />

It is now a pussy cat to fly and has the presence of the full size as long as you do not<br />

open the taps.<br />

My model weighs 3lb. 10oz. (1.64kg) without batteries, about the same as the IC<br />

version without fuel. Batteries-<br />

R/C Smart LiPo 2600 3s1p 6.2 oz. (174g)<br />

<strong>Flight</strong>Power LiPo 2200 3s1p 5.0 oz. (141g)<br />

Saphion LiPh 1200 4s2p 12.3 oz. (348g)<br />

So Saphions are heavier than LiPo, but safer, lighter than NiMH - time will tell.<br />
