G'day again Chris 44
P.S. I say that about the cut off coz I fried the 2000mha pack . Middle cell cooked.
The new set of 1500's (using a "Y" lead. I also replaced the std LiPo wire and plug with more robust wire and deans type plugs) I separated, and placed two paddle pop sticks between each cell to allow just a little air flow.
I have them sitting side by side on the end of the plate in the fuz ,with a gap between each pack motor wires hold them apart.
Make sure you cut the ends off the four screws holding the nose wheel on (replaced with a bit of lexan, a fast landing tore the standard plate off). These may pierce the LiPo pack (not good).
The slow speed performance is not too bad either with the wing not prone to violently tip stalling.
Use a dremel to cut through the cowl at the dummy exhaust stacks to allow air in/out.
If I have any more heat problems I expect to put in a couple of vent in the fuz. Enjoy ..... I am having a ball.
