The LA engine would be marginal for this plane to do what you are attempting. Trying the 11X4 would help. If you can get a FX 46 which would be a better choice. You may have access to Irvine engines. I have had very good luck with the 0.46 and the 0.53 which is in the same case and produces 1.7HP instead of the 1.4HP
A CG a little aft of the recommended might also help. Just do it a little at a time. Check the lateral balance and make sure you have enough right thrust in the engine for good vertical uplines.
